Crash when extracting the audio from a video created by mkvmerge

Reported by: Calmarius Owned by:
Priority: important Component: swresample
Version: git-master Keywords: crash SIGSEGV regression
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

Just cloned and built ffmpeg using the git command line I found in the download area. And compiled on 64 bit Linux.

I merged together some MKV-s into a single one using mkvmerge and tried to extract the sound for further processing. This caused ffmpeg to crash.

The full sample is available on my google drive:

https://drive.google.com/file/d/0B8rc3cKwPxmsS2xBcUlwNC1qcFU/edit?usp=sharing

Although it can be reproduced using a small sample too.

I'm not familiar with the codebase so I haven't tried to fix it my own, and I have a workaround: using the concat demuxer instead of concatenating with mkvmerge.

How to reproduce

$ ffmpeg -i "intermediate_cc.mkv" -af aresample=async=1000 -f wav "intermediate_fx.wav"

Detailed log

$ ffmpeg -v 9 -loglevel 99 -i intermediate_cc.mkv
