Pavel <[email protected]> added the comment: The reason it crashes is because the bitreader reads way past the end of GetBitContext buffer. As a workaround for my case I made a temporary patch like this: GET_VLC(code, re, &s->gb, s->vlcs[1][ac_index].table, 9, 2) if(s->gb.buffer + (re_index>>3) > s->gb.buffer_end) return -1;
The problem is that this test isn't appropriate for this place for performance reason I think. I put a static variable to see how many time that code gets executed and it runs like 3.5M times for the attached image. There must be some proper test before that to see if there is enough data can be read, or the bitreader somehow should allocate bigger buffer with zeros so that at least the reader won't read past the end. I tried to debug, and I don't know where to put proper test to se ________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/issue2117> ________________________________________________
