#7647 new defect

Cannot Copy TrueHD/Atmos Audio

Reported by: eyecon Owned by:

Version: git-master Keywords: mpegts
Cc: Blocked By:
Blocking: Reproduced by developer: no
Analyzed by developer: no

Description

Summary of the bug: Splitting a large .m2ts results in an unknown format error. The large file plays perfectly as Atmos from an external HD to my BluRay? player. I need to cut it in half to burn it to 2 discs. I copied the extract to the same USB drive.

Fedora 29

Not certain how verbose this should be (and I want to eliminate a build issue). My apologies if I paste too much content:

Sample is needed.

comment:2 Changed 5 months ago by eyecon

Happy to do so but "be careful what you wish for." The original is a 90gb blu ray media file.

comment:3 Changed 5 months ago by jamrial

See https://ffmpeg.org/bugreports.html#SubmittingSampleMedia

Try cutting a small portion of the sample, enough to include a bunch of video and audio frames, then upload it somewhere.

  • Component changed from undetermined to avformat
  • Keywords mpegts added
  • Version changed from unspecified to git-master

Mostly a duplicate of #2622 / I am not convinced this ticket will still be reproducible once #2622 is fixed.

(Not just an enhancement request as FFmpeg writes an invalid output file without warning.)
