FFV1-HEADER-coder_type

Name

coder_type validity.

Definition

This test checks if the FFV1 coder_type is valid; for versions 0-3, valid coder_type values are 0 to 2.

Reproducibility

Get FFmpeg source code, configure it, then:

mv libavcodec/ffv1enc.c ffv1enc.c
sed -e 's/put_symbol(c, state, f->ac, 0);/put_symbol(c, state, 9, 0);/g' ffv1enc.c > libavcodec/ffv1enc.c
make
mv ffv1enc.c libavcodec/ffv1enc.c
./ffmpeg -f lavfi -i "color=c=black:size=2x2" -vframes 1 -pix_fmt gray8 -write_crc32 0 -c:v ffv1 -level 0 FFV1-HEADER-coder_type_MS_v0.mkv
