HLS fails to play due to JavaScript error in quality selection routine

Hello Sandor,

unfortunately I was not able to reproduce the bug. I opened https://foliovision.com/player/demos/hls-stream and played the last video. In that video I choose the 1080p quality. I could see the FVPlayerHLSQuality in browser localStorage was set to 3, as the qualities are internaly numbered as 0, 1, 2 and 3.

Then I played the first video, which only has 3 qualities. So there are internally numbered as 0, 1 and 2. But it would play just fine. Although with the auto quality selected as 1080p or the 3rd quality was not available.

I see that this is not perfect, but the issue we were facing is that during the video load the HLS.js doesn’t know which quality is using what bitrate. So our attempt to remember the choosen bitrate instead of a stream “number” has failed.

Maybe there is something special about your streams. For example I haven’t tested what happens if each video has different amount of audio tracks for different languages. But from what I’ve seen so far it should just work as these do not affect the internal numbering and in the worst case it would fall back to picking the quality automatically.

Thanks,
Martin

Hello Sandor,

thank you for posting these details. I was able to reproduce the issue using that. I’m not sure why the steps which I did worked fine though.

We have prepared this fix for the next FV Player release. To get the fix right now you can reinstall FV Player from this link: https://github.com/foliovision/fv-wordpress-flowplayer/archive/master.zip To do that you will have to first deactivate and delete the current FV Player plugin you are using. WordPress will warn you that you might loose settings and data, but it’s not the case with our plugin, no settings now videos will be lost. Or you can just replace the plugin files via FTP.

Thanks,
Martin
