This supports quicksync encoding?
Quick! Someone tell the kodi developers that qs now works on linux for encoding!

i guess its only for Windows. But even on Windows its run not very well. I have 80% CPU (i5-4570) Usage and only ~37fps.

I'm reading this article and go "wait, MMAL encoding was added?". I only knew about decoding. And well, after checking, it's a mistake in the article. While MMAL does provide encoding, only the decoding part is in ffmpeg 2.7

For those who don't know, MMAL is the Multi-Media Abstraction Library used on the Raspberry Pi as an alternative to OpenMax. VLC and Kodi already had direct MMAL support for some time. Now mpv also supports it, by wrapping the ffmpeg code.

^Yes, thanks for pointing that out. Full changelog:

 
 version 2.7: - FFT video filter - TDSC decoder - DTS lossless extension (XLL) decoding (not lossless, disabled by default) - showwavespic filter - DTS decoding through libdcadec - Drop support for nvenc API before 5.0 - nvenc HEVC encoder - Detelecine filter - Intel QSV-accelerated H.264 encoding - MMAL-accelerated H.264 decoding - basic APNG encoder and muxer with default extension "apng" - unpack DivX-style packed B-frames in MPEG-4 bitstream filter - WebM Live Chunk Muxer - nvenc level and tier options - chorus filter - Canopus HQ/HQA decoder - Automatically rotate videos based on metadata in ffmpeg - improved Quickdraw compatibility - VP9 high bit-depth and extended colorspaces decoding support - WebPAnimEncoder API when available for encoding and muxing WebP - Direct3D11-accelerated decoding - Support Secure Transport - Multipart JPEG demuxer

That's really odd. I've seen benchmark sites where it encodes at monstrously fast rates (no idea about CPU utilization but it's gotta be better than x264).
It may be a hard api to use but some apps have clearly managed to make great use of it.
I'd really like to know what specifics are difficult with vaapi.
