[FFmpeg-devel] [PATCH 3/6] avformat/aviobuf: Don't use NULL as src for memcpy

This might happen in avio_write() if size == 0 when the direct codepath is taken. It is undefined behaviour according to the spec although it happens to work in practice. Fixes the webm-webvtt-remux FATE-test under UBSan. Signed-off-by: Andreas Rheinhardt --- libavformat/aviobuf.c | 4 +++- 1 fi
