Audio out of sync in composed video created using the concatenation pipeline #2854

Closed AmraniOmar closed 3 months ago

What happened and what did you expect to happen?

The composed video generated using the media concatenation pipeline has an out of sync audio. The composed video chunks look good and the issue seems to only occur during concatenation.

I tried to concatenate the chunks manually using ffmpeg and it worked as expected.

Have you reviewed our existing documentation?

All mentioned pipelines stopped successfully. I did a test with exact same capture and concatenation pipeline configurations, the audio and video were sync. Is the issue still happening? if yes, could you request AWS support case and we can exchange more information from support case.
