Sound completely garbled in Big Buck Bunny Live #104

Closed jgongo closed 4 years ago

jgongo commented 4 years ago

While testing the sample application I found that the sound in the Big Buck Bunny video is completely garbled. The problem may be related with an incorrect bitrate, as the sound is played in high frequency and with gaps in between.

Tested on an iPhone 7 Plus and iPhone X.

You can find attached the log of the first 10 seconds of playback:

Can you try again with the latest master? I cannot reproduce any error with an iPhone 6.

TheModMaker commented 4 years ago

Closing due to inactivity. If this is still an issue on the latest master, say something and we can reopen and investigate.

So now, I can reproduce with the Live version, but the VOD version plays fine for me.

@TheModMaker Sorry for not answering, I was fired and I'm no longer working on this project. Thanks a lot for your support! Good luck.
