Replying to cehoyos:

Please also provide valgrind output.

I am Windows User,so I can't. sorry.

comment:4 Changed 5 years ago by cehoyos

Sorry about my suggestion, please recompile with --disable-optimizations --enable-debug=3 and try to improve the gdb output.

comment:5 Changed 5 years ago by Einguste

From a quick look, the backtrace indicates a problem that cannot be fixed within FFmpeg.

comment:8 Changed 5 years ago by michael

  • Resolution set to invalid
  • Status changed from new to closed

could be wrong of course but this looks like a bug in libvpx to me too
that is it seems to crash if flushed before encoding anything
we still might want to add a workaround for this though, not sure
