I'm using the newest version of ffmpeg I can find: I also have been unable to find good examples of using more than one QSV enabled filter at the same time. Option 'async_depth' not found Error initializing filter 'vpp_qsv' with args 'cw=628:cx=0:w=640:h=480:async_depth=4' Error reinitializing filters! Failed to inject frame into filter network: Option not found Error while processing the decoded data for stream #0:0 'vpp_qsv=cw=628:cx=0:w=640:h=480:async_depth=4'Įven though there are examples posted that say it will, and the web page posted above says that async_depth is a valid parameter.

The few examples I've been able to find in various places (including stackoverflow) do not work.īy experimentation, I've found that this works:įfmpeg -hide_banner -init_hw_device qsv=qsv -hwaccel qsv -i 'input.mts' -c:a aac -c:v h264_qsv -preset veryslow -vf 'vpp_qsv=cw=628:cx=0:w=640:h=480' -q:v 30 'output.mp4'

It's a start, but it has no examples of what the arguments actually do or how to use them.

I've found the codec and at least one QSV filter which really speed up decoding and encoding AVC (x264) videos.īut the experience is extremely aggravating, as there is no proper list anywhere that I can find on what the filters and arguments actually are. I have a PC running Windows which is QSV capable.
