Segfault with fuzzed file (mkv demuxer) #1448

Jan 9, 2015
The VP9 codec parser has a bug: it doesn't set the data/size pointers passed to it. As I understand, it must always do this, and in fact, if it doesn't some libavcodec generic code would be in trouble too. This helps with #1448, but is not the full fix for it. The codec parser must be fixed in libavcodec itself.
This is not mpv's fault. Patch to ffmpeg sent. I painted it over anyway with the commit above. |
Oh well may as well close this. |
