Unfortunately the current implementation of qsv modules of ffmpeg does use own standalone MXF session. So there are copying from GPU memory to system memory and back are existing during transcoding. Also here software scaler uses when you transcode 1920x1080 ==> 1280x720. We a working under possibility to create complete pipeline into GPU: [qsv_dec]==>[qsv_vpp(scaler)]==>[qsv_enc] But I can not say currently when exactly it will available. -- Best regards, Ivan mailto:ivan.us...@nablet.com _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
