This error happens if cutlists are used and also if not.

Anything else you need? Thanks for your help.

Resetting defaults. It looks like the audio is being misidentified as MP3.

can you try calling mythtranscode with -O FFMPEGTS=1 and report if it fixes your problem?

[tobias.powalowski@…]

This does not fix the issue. Still the same. Already tried this with dekarl.

[JYA]

Same resolution as #12153

-O FFMPEGTS=1 wasn't actually used by mythtranscode.. now it is
