Have you read the FAQ and checked for duplicate open issues?

Yes.

If the problem is related to FairPlay, have you read the tutorial?

Not related, the video doesn't protection.

What version of Shaka Player are you using?

4.11.0

Can you reproduce the issue with our latest release version?

I'm not in the lab with Tizen 5.5 TV, will try it when I can.

Can you reproduce the issue with the latest code from main?

Same as above.

Are you using the demo app or your own custom app?

Custom app

If custom app, can you reproduce the issue using our demo app?

Will try it when I can.

What browser and OS are you using?

Tizen 5.5

It work as expected on another Tizen 6 TV.

For embedded devices (smart TVs, etc.), what model and firmware version are you using?

Model: TU6900 Crystal UHD 4K Smart TV 2020

What are the manifest and license server URIs?

manifest URL license server is not needed.

This happens only with DASH, when playing HLS, it works as expected.

What configuration are you using? What is the output of player.getNonDefaultConfiguration()?

{
  "manifest": {
    "retryParameters": {
      "maxAttempts": 6
    },
    "dash": {
      "ignoreSuggestedPresentationDelay": true
    }
  },
  "streaming": {
    "safeSeekOffset": 0,
    "autoLowLatencyMode": true,
    "preferNativeHls": true
  }
}

What did you do?

It sets playback rate with videoElement.playbackRate = 1.5.

What did you expect to happen?

The video should play with 1.5x playback rate.

What actually happened?

Video stuck, play / pause also doesn't work

Are you planning send a PR to fix it?

I have no idea for the cause, but I an willing to send a PR if we can confirm this is a Shaka player bug.

Hi @joeyparrish and Shaka Player Team,

The issue preconditions are:

Some of our video content provides DASH only, so we can't go with HLS only solution.

Normally changing the playback rate on TVs doesn't work well, in fact it's not even supported on WebOS. To change the playbackRate try using player.trickPlay(1.5) for example, tell us if this helps, otherwise it's a bug that you'll have to report to Samsung.
