#7733 closed defect (fixed)

Segmentation faults and double-free using spdif muxer

Reported by: barsnick Owned by:
Priority: important Component: avformat
Version: git-master Keywords: spdif crash
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

Summary of the bug:
Segmentation faults or double-free or similar encountered while muxing to spdif (not reproducible with other muxers).

This happens only on this x86 machine. I can't reproduce on x86_64, and don't have the compile environment in place for building x86 (32 bit) there.

Originally, I was trying to reproduce trac #7731, using

$ ./ffmpeg_g -i truehd_11mbit_bug.mkv -c copy -f spdif /dev/null -y

which consistently crashed, but no longer does with this given build:

How to reproduce:

Replying to cehoyos:

Please test this patch:

Good work!

This patch fixes both described crashes (the one with "-t 1" and with termination using 'q') using anoisesrc and the truehd encoder to spdif muxer.

It also fixes the crash with remuxing the TrueHD (in MKV) input file from #7731 to spdif.
