Environment
Steps to reproduce

1.Install Chrome version 53.0.2785 (you can use this link https://www.slimjet.com/chrome/google-chrome-old-version.php to install it) and launch it in unsecured mode to avoid cross-origin issues.
2. I created this sample test app that you can use to reproduce the issue :

`

<title>DASH.js 4.7.4 Stream Test</title> <style> body { font-family: Arial, sans-serif; text-align: center; margin: 20px; } 
    video {
        width: 100%;
        max-width: 800px;
        height: auto;
    }
</style>

DASH.js 4.7.4 Stream Test

<script src="dash.all.debug.js"></script> 
<script>

    const manifestUrl = 'https://live11-dash-preprod-he2.v-o.staging.cdn.orange.com/MnM3Syr0m1M-33yU8dNNYg/1733011200/428467/506237/54/cmaf/r11_pre10_ott/dash_high.mpd';
    const videoPlayer = document.getElementById('videoPlayer');
    const dashPlayer = dashjs.MediaPlayer().create();

    dashPlayer.initialize(videoPlayer, manifestUrl, true);
</script>
` 3. Play the stream
Observed behavior

After some time, there is no playback (sometimes, at the beginning, there is no playback)

@testeur-990 Thanks for providing the details. As a heads up, I won't be able to look into this for the next weeks as I am working on the remaining issues and todos for version 5: https://github.com/orgs/Dash-Industry-Forum/projects/8.

Some suggestions based on the logs:

  • Check the behavior in the nightly build of dash.js (v5) as we are not applying any changes to v4 anymore
  • Your logs show a very large clock offset between client and server, e.g Completed UTC sync. Setting client - server offset to -13669. A 13 second difference indicates timing issues. Make sure that your client clock is correct. You can also try to deactivate utcSynchronization in the settings and check if that helps. Also check the timing information in your MPD, e.g. <UTCTiming schemeIdUri="urn:mpeg:dash:utc:direct:2014" value="2024-11-07T17:16:24.889Z"></UTCTiming>
  • Check if you can reproduce this issue with other livestreams like the one coming from LiveSim2: https://livesim2.dashif.org/livesim2/segtimeline_1/testpic_2s/Manifest.mpd
  • Check other players like Shaka Player to see if the same behavior occurs.

Hello @dsilhavy ,
Ok, thank you. We will test your suggestions. However, we cannot test with dash.js 5 because we are blocked by the issue that I mentioned in this ticket #4619

#4619 is solved for now, the build is ES5 compliant

Hello @dsilhavy ,
The issue has been resolved by applying a workaround that limits the bitrate on the affected devices.
I will close this ticket now, and if we encounter the issue again, I will reach out to you
Thank you
