#7526: VAAPI HEVC Encoder Bitrate parameter no longer works in Master compared to 4.0.x -------------------------------------+------------------------------------- Reporter: jlsantiago0 | Type: defect Status: new | Priority: normal Component: | Version: git- undetermined | master Keywords: vaapi hevc | Blocked By: encode rate control | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- 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.
