[FFmpeg-devel] [PATCH] Fix target_level for EAC3.

Currently when using target_level with EAC3 it produces silence. This small patch fixes target_level for decoding EAC3. Example: ffmpeg -y -i /tmp/test.wav -acodec eac3 -dialnorm -14 -ac 6 -b:a 384000 /tmp/test.m2ts ffmpeg -y -target_level -24 -i /tmp/test.m2ts -acodec pcm_s16le -f matroska

If a hardware encoder is used, the pixel format may be a hardware pixel format. This leads to invalid VPCC atom being written, due to depth of hardware pixel formats being 0. To work around this, fallback on bits_per_raw_sample. Signed-off-by: Nikolas Bowe --- libavcodec/vaapi_encode.c | 2
