Summary of the bug: audio out of sync when playing ts file
How to reproduce:
$ ffplay http://pcuf.fi/~rasjani/koditest/yletv1_1080p.m3u8
I've been developing kodi addon for for a service that streams ts files via hls and it seems that their streams can't be played without audio lang with Kodi. I've spent yesterday communicationg and debugging the issue with following findings:
- streams can be played with web players GrindPlayer, FlowPlayer without audio sync issues
- streams can be played with VLC & QuickTime (osx 10.8.5) without audio sync issues.
- Kodi isengard beta1 & beta2 and master nightly build has audio sync issue. Master build is using ffmpeg 2.6.3. Verified that same is happening on OSX and Linux.
- Standalone ffplay has audio sync issue (tested only with ancient version of 2.3.2, on osx)
I've provided a small clip of example data here so that you can reproduce the issue here: http://www.pcuf.fi/~rasjani/koditest/
Folder contains few .ts files, playlists, my kodi.log and maybe some relevant chatter from #kodi which could point out where the issue actually is.
I was asked to open this bug report against ffmpeg based on irc conversation and discussion on my original bug report here: http://trac.kodi.tv/ticket/16122
This could be a content issue from transcoding the service does but then again, all other players i tried, did not have the issue of audio falling out of sync.
