Intel QSV: H.264 level is ignored
|Reported by:||alexpigment||Owned by:|
|Blocking:||Reproduced by developer:||no|
|Analyzed by developer:||no|
Summary of the bug:
For the h264_qsv encoder, specifying an H.264 level is quietly accepted (no errors or warnings) but not honored. Instead, the level is always automatically assigned.
Using Staxrip as a comparison, the Intel H.264 encoder does appear to support user-specified levels.
How to reproduce:
% ffmpeg -f lavfi -i smptebars -c:v h264_qsv -s 1920x1080 -aspect 16:9 -profile:v high -r 29.97 -t 5 -look_ahead 0 -level 4.1 output.mp4
See that the resulting video is reported as Level 4 in MediaInfo rather than Level 4.1.
