Summary of the bug: When I create a MP4 file with AAC Audio or MKV with
AC3 Audio the final file, the audio slowly over time drifts out of sync
with the video when playing back on a Samsung TV.
This is wierd for 2 reasons:
1. This ONLY happens with ffmpeg created MP4 and MKV files. I create the
same file with Handbrake it plays back fine with the Samsung TV
2. The file plays fine on other players (WMP, MCE, KMPlayer etc).
Not sure what it is about ffmpeg created MP4 and MKV files that cause the
audio to drift out. Is there some tag or setting I need to enable to make
it more compliant universally? What is Handbrake doing to make it play
fine. Not sure how to report this.
This it the command I'm using to create the file.
