#7526 new defect

VAAPI HEVC Encoder Bitrate parameter no longer works in Master compared to 4.0.x

Reported by: jlsantiago0 Owned by:
Priority: normal Component: undetermined
Version: git-master Keywords: vaapi regression
Cc: Blocked By:
Blocking: Reproduced by developer: no

Description

Summary of the bug:

In FFMPEG v4.0.2 you could use the -b:v parameter to set the target bitrate. And the Video output would reflect the bitrate specified on the commandline. That no longer works in git-master. You get rougly the same output no matter what you set for the bitrate.

How to reproduce:

ffmpeg -vaapi_device /dev/dri/renderD128 -i /mnt/share/content/yuv/lp/SVT_Park_joy_FR6001_7000_1920x1080p50.avi.yuv.y4m -vf 'format=nv12,hwupload' -c:v hevc_vaapi -b:v 2M -g 30 -bf 2 test-vaapi-2m.hevc

ffmpeg -vaapi_device /dev/dri/renderD128 -i /mnt/share/content/yuv/lp/SVT_Park_joy_FR6001_7000_1920x1080p50.avi.yuv.y4m -vf 'format=nv12,hwupload' -c:v hevc_vaapi -b:v 4M -g 30 -bf 2 test-vaapi-4m.hevc

ffmpeg version N-92314-g323c2cfd38

Manjaro Linux.

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

Notice that with 4.0.2 release build you can configure the bitrate and get different bitrate in the output. Granted the bitrate is higher than requested. Asking for 2Mbps achieves approx 3.2Mbps and asking for 4Mbps achieves approx 6.5Mbps

Using git-Master with the same parameters. The file sizes are roughly the same:
