What did you do?

1. Run playback
2. Select another audiotrack

What did you expect to happen?
Audio track changed, playback goes well

What actually happened?

After changing audio track or enabling text track the playback goes frame by frame (very slow), buffering is enabled and after each ~5seconds frame changes and audio doesn't play. No any errors in a console.

My code which select audio track:
this.player.selectAudioLanguage(audioTrack.language); this.player.selectVariantTrack(audioTrack);

Checked with Playready and Widevine, for all playback goes slowly

This sounds like it is probably a bug in the device firmware. It will be difficult for us to figure out, though, because we don't have a WebOS device set up yet.

In the mean time, can you please try our demo app and some of the content in it? We have both Widevine and PlayReady content available. Please click the "search" tab at the top of the app and filter from there.

If this is a content-specific bug, this will help us figure that out and decide what the next steps could be. If it is a firmware bug, it might be something you could work around with a change to your encoding & packaging.

@joeyparrish Please help me how to use your demo in TV and which one? What shall I load/build and run on TV?

[joeyparrish]

You could load https://shaka-player-demo.appspot.com/ on the TV's browser.

@joeyparrish I ran demo on WebOS and this problem is reproduced. On Tizen works well. But on WebOS video goes frame by frame. But it reproduced only on Live, on VOD all was correct. So the problem reproduces only on webos for live

[joeyparrish]

I wanted to update this issue and say that we still do not have a WebOS TV, and that WebOS is still in a "community supported" status. There is nothing we can do debug this issue at the moment. I would suggest checking for firmware upgrades to see if this might have been fixed already by LG.

@SunDr17, very similar to this problem #2327. Try this solution #1610 (comment).

[avelad]

Can you test with v4.3.4? Thanks!
