#7254(avcodec:new): ffmpeg h264_qsv encoder can not output QP to evaluate encoding quality

#7254: ffmpeg h264_qsv encoder can not output QP to evaluate encoding quality -------------------------------------+------------------------------------- Reporter: jianhui | Type: Status: new | enhancement Component: avcodec | Priority: normal Keywords: qsv encoder | Version: git- PSNR QP | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Summary of the bug: I use ffmpeg h264_qsv to do transcoding, and want to get the PSNR or QP after transcoding to evaluate encoding quality. Once the PSNR or QP is too low, I will change coding parameter to re-transcoding to meet the minimum quality requirement. But both PSNR and QP are not supported by latest h264_qsv.
