Seemingly Valid File Returns Transcode Error in FFmpeg #6027

Open joncameron opened 2 months ago

joncameron commented 2 months ago

Description

When submitting this file to Avalon, FFmpeg is returning a "contradictionary STSC and STCO" bad header error. The file, however, plays as expected in Quicktime and other common media playback applications.

Is there an FFmpeg option that would force the transcode without stopping at this error?

Maybe try -err_detect ignore_err?

No luck with -err_detect on this file.

I'd try asking Brian W. since he's an ffmpeg whiz.
