==== Summary of the bug:
While trying to apply a two-pass video encoding to a small mp4 video, we
encountered a heap-buffer-overflow bug in file: libavcodec/ratecontrol.c,
line: 560.
==== How to reproduce:
The bug is reproducible on the latest commit 34a47b97de.
The following builds ffmpeg:
{{{#!bash
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
./configure --disable-asm --toolchain=gcc-asan --disable-ffplay --disable-
ffprobe
make
}}}
Run the following command:
{{{#!bash
./ffmpeg_g -y -v 9 -loglevel 99 -i small_movie.mp4 -pass 2
small_movie_out.mp4
}}}
Options `-v 9 -loglevel 99` are optional and were only added to produce
verbose logs.
==== Console output:
