Comment (by xanadonf):
''>>Is the crash also reproducible with ffmpeg -i sample.mp4 -an
output.webm ?''
--> yes
''>>Is the problem only reproducible with one specific sample? If yes,
please provide it.''
--> no. it happens with any sample.
''>>If you want support with this problem you will have to provide
backtrace etc. as explained on http://ffmpeg.org/bugreports.html which
means you have to install a shared libvpx with debug symbols.''
--> let's continue :
