This article will show how to use the Free Backup License, which comes with every PLAYDECK License. The Backup License functions as follows:

• Can be used with ANY PLAYDECK License (Dongle, Shop, Offline)
• Can be used on ANY PLAYDECK-PC in the same network
• Multiple Clients are supported
• 24/7 operation is NOT supported (max 24h per session)

1. Setup

On your MAIN System (the one WITH the License), you don’t have to do anything: The BACKUP LICENSE SYSTEM is enabled by default. It will use the WebSocket Port 11411, so make sure this Port is not blocked:

On the CLIENT System (the one WITHOUT the License), you perform a regular PLAYDECK installation, nothing special here: PLAYDECK will not start in TRIAL MODE with the watermark:

Now we need to tell CLIENT PLAYDECK, where to find the MAIN PLAYDECK, by providing the IP address of MAIN. To receive the IP address of your MAIN, you can simply open the ABOUT BOX in PLAYDECK (Main Menu > License > About):

On your CLIENT, go to Application Settings, enter the IP address of MAIN PLAYDECK and click TEST IP NOW. The CLIENT now tests the Network connection and searches for a valid License on MAIN. If you don’t see the following INFO POPUP, please check your MAIN License and your Network connection between MAIN and CLIENT:

You can now enable the feature by clicking BACKUP-SYSTEM. PLAYDECK will restart now with the exact same License of MAIN. You can verify, the CLIENT is using the Backup License correctly in several Displays:

Note: If the CLIENT has a valid License itself, the License of MAIN will NOT be used.

2. Rules of Backup-License

The Backup-License is not meant for 24/7 operation, but to provide a fail-safe for immediate operation, e.g. in a live production, and without the need to buy a secondary license, just to have a backup system for some use cases.

For unattended 24/7 operation, you would need to purchase a secondary license. Please contact use at [email protected], if your next License is for Backup only, and we will provide you with a appropriate discount.

The MAXIMUM RUNTIME of your BACKUP LICENSE will be:
– 2 hours, if the MAIN gets disconnected or closed
– 24 hours, if then MAIN stays online

PALYDECK will terminate the CLIENT without prior warning. So please make sure, to bring the MAIN back online within the 2 hour window, or to restart both MAIN and CLIENT within the 24 hour window.

You can control the remaining RUNTIME in the Settings of the CLIENT:

This article will show how to create a Slideshow with Transitions and output on the same Monitor.

1. Creating the Show

Open the integrated File Explorer by clicking the right-arrow between the Playlists. The search for your images folder, select all images and add the to the Playlist by Drag Drop:

Select any Clip in the Playlist and press CTRL+A to select all Clips, then select the Icon for DURATION and enter a suitable duration for each image, e.g. 15 seconds:

While al Clips are still selected, click the Icon TRANSITION next and add any transition. In this case we use a smooth long Fade Transition:

At the bottom of the Playlist you can see the total duration of your Slideshow:

2. Playing the Slideshow

You simply double-click the first Clip (or use Buttons CUE+PLAY), then double-click the Preview Area (or right-click and select FULLSCREEN). Your Playout will now be maximized to your Monitor Size, at maximum Quality. And the Mouse Cursor will be hidden. Use ESC to exit Fullscreen.

Note: During Fullscreen, you can use the SPACE Key to pause/u-pause Playback.

You can also output the video signal on a second monitor, or send it to your TV. You could also send it via NDI to another PC and open the signal with PLAYDECK (use the free Backup License), or VCL Mediaplayer or any other 3rd party app:

This article will show how to use Commands to control your Playout.

In this article:
→ Example: CUE+PLAY multiple Channel
→ List of all Commands and where to add them
→ Send Commands from other Apps

Example: CUE+PLAY multiple Channel

We want to create an Action Button, which will CUE several Output Channel and PLAY them simultaneously (almost synced).

Create a new Action Button by clicking on it and select COMMANDS, then EDIT COMMANDS:

Add this Line under “COMMANDS – Internal”:
<cue|1|1><cue|2|1><wait|1000><play|1|1><play|2|1>

This will CUE Channel 1 and 2 (1st Clip 1st Block), then wait 1000ms (for caching), then PLAY both Channel.

List of all Commands and where to add them

The List of all Commands can be quickly opened over PLAYDECK’s Main Menu:

Commands can be added to:

• Action Buttons (Start, End)
• Overlay Button (Start, End)
• Clips (Any Time)
• Blocks (Start, End)

Mostly via this Icon:

Send Commands from other Apps

We have a separate article on how to control PLAYDECK with Companion.

But what, if it is not Companion, but a different 3rd party App? First, you would need to enable TCP Commands. This will open PLAYDECK up to receive and execute Commands from external sources:

In your 3rd party app, connect to PLAYDECK via TCP and send one or multiple Commands. In this Sample we use Hercules to send a Command, which will start Streams 1 and 2:

This article will show how to use bitfocus Companion together with PLAYDECK. Companion has a ready-to-use module for PLAYDECK. This is the most comfortable way to connect PLAYDECK to your ATEM Mixer or STREAMDECK.

The Companion Module has been developed and is maintained by Nick Semonov. He is a Community Developer and also a great guy to work with.

In this article:
→ Installation
→ Button Page with Presets
→ Custom Commands instead of Actions
→ Custom Button Feedbacks

Installation

1. Start PLAYDECK, so Companion can find it

2. Download and install the latest stable Version of Companion

3. Start Companion and add the PLAYDECK Module

4. You are done, if Companion shows a GREEN Checkmark for this Connection. If you cant get a Connection, please disable your Firewall or allow TCP Port 11411.

Button Page with Presets

We will use Companion Presets to quickly create a fresh Page of Buttons for a casual Playout Situation.

1. Create a new Page, then go to PRESETS and select PLAYDECK

2. For our Sample we specifically want to target Channel 1. You could also use LISTS, which are dynamic and use the visible Channel in PLAYDECK (Left and Right). You could also control your ASSETS (Streams, Recordings). Select CHANNEL 1 to continue

3. With Drag & Drop we create a simple Playout Solution: Play Control with some Overlays. The Buttons are added with FEEDBACKS, meaning: You will get a RED Button according to the PLAY STATE (CUE, Playing, Paused, Stopped).

4. The PLAY Button also shows the remaining Clip Time during Playout:

5. Some Buttons need more Information for you, like the START OVERLAY Button. It needs to know, which Overlay(s) should be started:

Custom Commands instead of Actions

We will add any PLAYDECK Command to a Companion Button. This is useful, if you are more of a “code” type of person or if there a new Commands in PLAYDECK, which are (not yet) available in Companion. Its also possible to add multiple Commands at the same time.

1. We create a new Button and add a new Action. We now select CUSTOM COMMAND and click DONE

2. In PLAYDECK we open the COMMANDS LIST to review, which Command we want to use

3. We decide that we want to start multiple Overlays on several Channel and after that start 2 Streams:

<startoverlay|1|1+3>
<startoverlay|2|1+5>
<startstream|1>
<startstream|2>

4. We wrap up all Commands into one Line and copy it into the COMMANDS Field. If we then press our Button, we start our Overlays and our Streams, as all Commands are executed in the written order.

5. Another good example is starting 2 Channel synchronized:

<cue|1><cue|2><wait|1000><play|1><play|2>

This will CUE both Channel, then wait 1 Second for CUE being ready (Clip Caching), then PLAY both Channel.

Custom Button Feedbacks

Instead of using the pre-defined Feedbacks (e.g. PLAY STATE), you can use Companion VARIABLES to use many more Feedbacks. In this example we will start a specific Block and show its remaining Time on the Button.

1. We add a new Block to Channel #1 in PLAYDECK and rename it “MAIN PROGRAM”

2. Now we add a new Button to Companion and assign the CONTROL PLAY FLEX Action to the Button.

3. The PLAY FLEX Action allows us to play a Block by Name (instead of ID). We use the PATTERN “b:main c#1” to start our Block, as described in the COMMANDS LIST (PLAYDECK > Main Menu > Documentation):

4. We now have a Block Play Button, but we also want the remaining Block Time to display, once the Block is playing. For this we need to add a custom Feedback to the Button, which will check “some” variable and do “something”:

5. We check against the current playing Block by searching for “block name” in the VARIABLE field and add our Block “Main Program” as VALUE:

6. We then add TEXT as new STYLE PROPERTY, since our intention is to show the remaining Block Time:

7. Add “$(Playdeck:channel_1_block_remain)” as BUTTON TEXT STRING, and our Button is finished:

8. But how did we receive our BUTTON TEXT STRING? Companion will show you all available VARIABLES you can use in PLAYDECK. You can then click the small COPY ICON to transport the Variable to your Buttons:

This article will show how to load and edit YouTube Videos.

1. Load YouTube into PLAYDECK

You can directly Drag Drop any YouTube URL from your Browser to PLAYDECK:

Or you can use the Stream Drag Drop Icon to paste/edit the URL:

Your YouTube Videos is ready to play out-of-the-box. The quality will be pre-selected dependent on your Playlist Video Format and the Formats provided from YouTube.

Note: Avoid using long YouTube Links with Playlists like “…?v=0oIIRc0zc_U&list=RD0oIIRc0zc_U”, as they might not work or cause Lag/Stutter. We recommend using short links like “…?v=0oIIRc0zc_U”.

2. Update YouTube Driver

Should the added YouTube Clip be shown as UNPLAYABLE/RED in PLAYDECK, please update the integrated YouTube Driver. Chances are, YouTube made changes to its platform and you need a newer driver from us:

3. Change Quality, Video and Audio

YouTube Videos are always available in different qualities. You can switch Video Tracks by right-clicking the YouTube Video:

Note: YouTube provides combined Video+Audio Tracks, which are much faster. If you switch to non-combined Video Track, caching can take much longer and seeking can desync video/audio.

Please use these guidelines to choose or build the right hardware for your PLAYDECK system. While PLAYDECK can play virtually any codec on any Windows machine, professional video playout requires robust hardware to guarantee zero frame drops.

System Configuration Archetypes

Choose the production archetype below that aligns with your upcoming project requirements.

1. The “Set-and-Forget” Fixed Installation

Designed for: Stationary installations, corporate showrooms, medical facilities, schools, and digital signage.

If you need a compact, dedicated unit to seamlessly manage 1 or 2 channels of standard H.264 playback, look for small form-factor builds that do not compromise on hardware decoding.

• Our Recommendation: A performance-tier mini PC like the ASUS NUC 14 Performance or ASUS ROG NUC. Avoid the standard baseline office NUC models. Ensure your chosen mini PC configuration specifically includes a discrete NVIDIA RTX GPU (such as an RTX 4060 or 4070 laptop chip) to guarantee stutter-free H.264 timeline performance.

2. The Mobile Video Director

Designed for: Event tech providers, traveling AV crews, festivals, and remote live streaming.

If you deploy temporary live setups, push video to regional LED walls, or broadcast from mobile command stations, a thermal-efficient mobile rig is mandatory.

• Our Recommendation: High-performance, current-generation workstation or gaming laptops engineered for continuous maximum thermal load (such as the XMG ULTRA or Lenovo Legion Pro series). For broadcast environments, scale the laptop’s connectivity by pairing it with a Blackmagic UltraStudio capture and playback device via a high-bandwidth Thunderbolt interface.

3. The Broadcast & Studio Professional

Designed for: TV stations, multi-screen matrix setups, and 24/7 master control environments.

When your infrastructure handles simultaneous UHD/4K master outputs, heavily utilizes network protocols like NDI®, or handles deep layers of graphic lower-thirds, you require raw hardware overhead.

• Our Recommendation: A custom-built rackmount or tower workstation pairing a multi-core processor with a desktop NVIDIA RTX 4070 / 4080 GPU or higher, paired with hardware-locked internal SDI I/O cards (such as the Blackmagic DeckLink series).
  
  

Legacy Systems & The CPU-Only Safety Net

If your team is working with an existing office computer or an older laptop running basic integrated graphics (like Intel UHD Graphics), you do not necessarily have a hopeless case. PLAYDECK can adapt to older architectures if you configure the processing pipeline correctly.

If you encounter stuttering, timeline lag, or stability problems on older office hardware, apply this configuration fallback inside the application settings:

• Open your PLAYDECK settings.
• Locate the Application configuration settings.
• Switch the GPU Pipeline parameter to <CPU only>.
• Switch the Decoding GPU parameter to <CPU only>.

Important Deployment Caveats for Legacy Hardware:
When fallback mode is active, your system CPU takes over the entire workload. To ensure successful execution without frame drops, you must limit your project scope: restrict your playout to a single channel, downscale your timeline target to standard 1080p Full HD, and ensure your playback clips match a highly optimized, lightweight playback format.

Technical Performance Metrics (For Professionals)

If your engineering department is evaluating existing inventory or sourcing custom parts, use these performance baselines.

1. The GPU Decoding Hierarchy

While alternative graphics options exist, they are not architecturally identical for live broadcast workloads:

NVIDIA RTX Architecture (Industry Standard): Highly recommended. NVIDIA’s dedicated NVDEC/NVENC blocks provide optimal hardware decoding throughput for standard broadcast clip formats, specifically H.264 and HEVC video streams.

Intel ARC Systems: Suitable for secondary deployments. They handle modern AV1 streams effectively and offer competent DVB 4:2:2 encoding, but do not match the overall parallel decoding capacity of an NVIDIA workstation chip under multi-channel production loads.

Intel UHD Onboard Graphics: Strictly intended for lightweight, single-channel legacy fallback usage using the CPU-only adjustments outlined above.

AMD Radeon Platforms: Hardware-accelerated video decoding via AMD is not officially supported inside PLAYDECK.

2. Target PassMark Benchmarks

If you are unsure of your current hardware performance levels, you can check your system components directly on the official PassMark Software Benchmark Database.

Playout Scale	Target CPU PassMark Score	Target GPU PassMark Score
Single-Channel	25,000+	9,000+ (e.g., Dedicated NVIDIA RTX)
Dual-Channel	35,000+	12,000+ (e.g., Station-class Workstation)
4 to 8 Channels	50,000+	15,000+ (High-Tier Desktop RTX)

3. When to Provision an Advanced CPU

Your system’s central processor handles severe system strain if your workflow requires any of the following processing types:

• High-bitrate master formats that bypass GPU decoding pipelines entirely (e.g., Apple ProRes, HAP, or Avid DNxHD).
• Multi-destination network routing using NDI® outputs, as these matrix encoders rely purely on your host processor.
• Intense deployment of live-rendered HTML graphics, data-driven lower-thirds, or real-time alpha-channel video overlays.

Hardware Output Cards

To bypass operating system desktop layer interference, maximize color accuracy, and maintain a strict hardware-locked framerate control signal, offload your primary feeds to a dedicated PCIe or Thunderbolt video interface.

PLAYDECK maintains native compatibility with major broadcast hardware lines, including:

• Blackmagic Design (DeckLink / UltraStudio)
• AJA Video Systems
• Deltacast & Bluefish444
• Magewell, Osprey, and Stream Labs
• ASIO & Dante Virtual Soundcard audio endpoints

Pre-Flight Troubleshooting Checklist

If you experience playback stutter, audio sync issues, or unexpected lag during configuration, run through this quick self-diagnostic checklist before contacting support.

• Check the <CPU only> toggle: If running on an office laptop with integrated Intel graphics, ensure both GPU Pipeline and Decoding GPU are set to <CPU only> in the settings menu.
• Verify Windows Power Plans: Laptops often throttle performance on battery. Connect your device to a power outlet and change your Windows power plan to High Performance or Best Performance.
• Monitor the Playback Clock: Look at the integrated performance monitor in PLAYDECK during playback. If the frame counter drops or turns red, your hardware is hitting a performance bottleneck.
• Match Output Refresh Rates: Ensure the refresh rate of your Windows display settings (e.g., 50Hz or 60Hz) exactly matches the output frame rate of your project settings in PLAYDECK.
• Inspect the Clip Codec: If a specific video causes issues, verify its properties. High-bitrate 4K files or uncompressed formats will overwhelm basic system processors. Use an H.264 MP4 file for the safest baseline test.
• Update the I/O Drivers: If using Blackmagic DeckLink or UltraStudio hardware, ensure you have the latest version of Desktop Video installed via the Blackmagic Design support page.

Sometimes, in Live Productions, you have to send the Audio delayed compared to the Video, to compensate for the processing Lag of huge LCD Screens (Lipsync). Or add a Limiter/Gate to the Microphone Input Audio.

In this article:
→ Simple Audio Delay
→ Copy Audio and Delay
→ More Audio Filter

Simple Audio Delay

This is actually pretty fast to implement in PLAYDECK. You add the ADELAY Audio Filter to the Channel like this. In this example we set 600ms Delay for Audio Channel 1 and 2:

This can also be set to INPUTS to compensate for any incoming Lipsync Issue.

Copy Audio and Delay

You can also COPY the Audio Channel 1 and 2 to Audio Channel 3 and 4 and delay those. The use case here is, that the Audio Mixer Person has Live Preview Audio.

This needs to be done on the Playlist Level, so clear any Audio Filter in the Settings.

First, make sure to increase the Audio Channel for your Output Channel, otherwise all Audio Channel above 2 will not be processed:

The Right-Click any Playlist Item and select AUDIO CHANNEL MAPPING:

This will copy Audio Channel 1 and 2 to Audio Channel 3 and 4:

Now right-click the Playlist Item again, select AUDIO FILTER and add the ADELAY Filter, but only for Audio Channel 3 and 4:

More Audio Filter

For a complete List of all Audio Filter, click SHOW SAMPLES. This will open a TEXT FILE with Examples.

This article will show how to setup Video Engine Logging.

1. Setup Logging

Start PLAYDECK, open Settings, and select the APPLICATION tab. At the bottom of the page, you will find the configuration options.

Output Folder: Choose your destination directory. This can also be a shared network folder.

Storage Warning: Logs can easily consume up to 1 GB per minute (at Verbosity 0 with all modules enabled). Ensure you have sufficient free disk space based on how long it might take for the issue to occur.

Verbosity: Always start logging with 0 – trace. This ensures the Video Engine developers receive all necessary information.

Modules: Select all to begin with. If the log files become too large, you can reduce their size by focusing on specific modules:

The first thing to setup is your Output Folder for the Log Files. This can be a shared Folder on your Network. Logs can easily consume up to 1 GB per Minute (on Verbosity 0 and all Modules). Plan enough free disc space, depending on the estimated time until Bug occurrence.

The next setup is Verbosity: Please always start Logging with 0 – trace, so the Video Engine Devs have ALL information.

With the Modules setting we pick all to begin with. If Log Files get to big, we can reduce the size by focussing on specific modules:

• all: Logs everything.
• playlist,file,codecs: Covers playout, file decoding, and clip loading/playing errors.
• writer: Covers streams, recordings, and encoding.
• network: Covers streaming protocols.
• renderer: Covers device output and NDI.
• live: Covers live inputs.
• device: Everything related to hardware devices.
• blackmagic: Everything related to Blackmagic Design hardware.

Split Option: This depends on how many channels you are running, as every channel operates on its own process. If you use more than 2 channels, we highly recommend enabling the Split option.

2. Start / Stop Logging

To catch a bug on the fly, you will need to start logging, reproduce the issue, stop logging, and then send the files to the development team.

Timing: You can START and STOP logging at any time. This allows you to prepare your playlist or devices beforehand. Minimize the time between starting and stopping to keep the overall file size manageable.

Session Folder: Once you click START, a new subfolder named after the current timestamp (e.g., 2026-05-16__01-20-00) will be created in your designated logging path.

Stopping: Once the bug occurs, click STOP. Wait at least 10 seconds to ensure all active log processes finish writing to the disk.

Compression: Open your logging path and locate the session folder. Right-click the folder, select Compress to…, and choose 7z (preferred) or ZIP. Compression may take some time depending on the file size.

Now we need to ZIP the contents of the session folder. Identify your session folder by START time. Then right-click your session folder, select Compress to and pick 7z File (if available) or ZIP File. Now lean back, compression could take some time.

3. Uploading Logs

Please upload your compressed log files using our official download portal:

https://download.joy-event-media.de

1. Drag and drop your ZIP/7z file into the browser window or use the file browser.
2. Click UPLOAD.
3. Once complete, click COPY to copy the generated download link to your clipboard.
4. Send an email to [email protected] and paste the download link into the message.

Note: Without this specific download link, our team cannot access your files due to data protection policies.

4. Cleanup

Make sure to delete the original log files and session folders after successful compression and upload to free up disk space. PLAYDECK does not automatically delete or clean up old log files.

SCTE-35 markers travel in MPEG transport streams. In PLAYDECK that means UDP, SRT, DVB-compatible streaming, MPEG-TS recordings, and HLS segments — not SDI and not MKV/RTMP.

On SDI, use SCTE-104 instead: Using SCTE-104 on SDI.

Full from→to matrix: Closed Captions & SCTE — Overview.

PLAYDECK lets you author your own SCTE-35 XML (flexible for any receiver). Placeholders fill in clip/block timing and IDs.

Enable SCTE-35

SCTE-35 is not on by default for streams/recordings. Open Parameter and set:

embed_scte35='true'

Works with	Does not apply
UDP, SRT, DVB-compatible (format mpegts/dvb), MPEG-TS file record, HLS segments	SDI, NDI, MKV, RTMP/FLV

The video codec does not matter for SCTE-35 (unlike Closed Captions / embed_cc).

UDP URL tip: use your LAN IP (e.g. udp://192.168.x.x:5000?pkt_size=1316). Prefer not 127.0.0.1.

You can combine with captions when needed:

embed_scte35='true' embed_cc='true'

No conflict was found between SCTE-35 and embed_cc on MPEG-TS streams (unlike SCTE-104 + active CC/ASS track on SDI — see overview limits).

Where to attach markers

Attach SCTE commands to:

• Clips (any play position)
• Blocks (start / end)
• Overlays (show / hide)
• Action buttons

Set the command type to SCTE-35 (not SCTE-104) when the target is a stream or TS file.

XML examples & placeholders

Formats vary by receiver. The samples below work well with many splice workflows (including Nimble). Ask your provider if unsure.

Splice with duration (auto-return)

<SpliceInfoSection>
  <SpliceInsert
    spliceEventId="4157"
    outOfNetworkIndicator="1"
    spliceImmediateFlag="1">
    <Program />
    <BreakDuration
      autoReturn="1"
      duration="{clipduration}" />
  </SpliceInsert>
</SpliceInfoSection>

{clipduration} is filled by PLAYDECK (same idea as {blockduration}).
Manual duration: clip length in seconds × 90000, rounded (90 kHz timescale).

CUE-OUT / CUE-IN pair

<SpliceInfoSection>
  <SpliceInsert
    spliceEventId="4157"
    outOfNetworkIndicator="1"
    spliceImmediateFlag="1">
    <Program />
  </SpliceInsert>
</SpliceInfoSection>

<SpliceInfoSection>
  <SpliceInsert
    spliceEventId="4157"
    outOfNetworkIndicator="0"
    spliceImmediateFlag="1">
    <Program />
  </SpliceInsert>
</SpliceInfoSection>

outOfNetworkIndicator 1 = leave program (CUE-OUT), 0 = return (CUE-IN). Pair by spliceEventId.

Placeholders

{timestamp} {timestampunix} {airtimenext} {airtimenextunix} {plannednext} {plannednextunix} {clipid} {blockid} {blockduration} {clipduration}

Local stream loop test

1. Channel 1: start UDP or SRT with embed_scte35='true'.
2. Channel 2: play the same URL as a stream clip.
3. Action on Ch1 with SCTE-35 XML → Event Log: >> on Ch1, << SCTE-35 on Ch2.

Optional: record to a .ts file with embed_scte35='true', fire markers while recording, then confirm in DVB Inspector and by playing the file in PLAYDECK (<<). See Recording CC & SCTE.

Forwarding between streams

PLAYDECK can forward SCTE-35 across stream inputs/outputs (e.g. SRT → UDP or Ch1 → Ch2 → Ch3 over UDP).
Receivers show << on each hop when embed_scte35 is enabled on each outgoing MPEG-TS stream.

Not supported: automatic SCTE-104 → SCTE-35 when an SDI source is streamed to IP. Send SCTE-35 on the streaming channel instead.

HLS output

If you select Apple HLS, PLAYDECK writes a local .m3u8 (+ segments), not a live CDN publish by itself.

• PLAYDECK does not write SCTE/CUE tags into the .m3u8 manifest.
• SCTE-35 / CC can still be present in segments. Playing the m3u8 in PLAYDECK can show CC and << SCTE-35.
• For manifest-based ad markers (e.g. #EXT-X-CUE-OUT), use a server such as Nimble (below) or another packager that converts SCTE-35 → HLS cues.

Test with Nimble Streamer

Typical path: PLAYDECK UDP + embed_scte35 → Nimble → HLS with cue tags.

1. Install Nimble; enable SCTE in nimble.conf (example):

Restart the Nimble service after editing.

scte35_processing_enabled = true
scte35_forwarding_enabled = true
hls_ad_scte35_forwarding_enabled = true
hls_ad_marker_format = cue
hls_ad_splice_out_cont_marker_enabled = true

2. In WMSPanel: MPEG-TS In (UDP) matching PLAYDECK’s target; MPEG-TS Out / HLS as needed.
3. PLAYDECK stream URL → that UDP port; video codec free (e.g. H.264); embed_scte35='true'.
4. Attach SCTE-35 to clip start (or Action); start stream; verify cues in Nimble logs and in HLS chunk playlists (browser Network tab).

Logging & tools

• PLAYDECK SCTE Event Log: >> sent, << received.
• DVB Inspector / TSDuck: inspect SCTE-35 inside .ts files or captures.
• MediaInfo: great for CC tracks; often does not list SCTE-35 clearly.
