[Libav-user] vaapi h.264 decoding with libav

[Nikita Orlov]

Hello!

I am using ffmpeg/libav 2.5.3 on Haswell 4770 (HD 4600).
I am using libav for decoding h.264 video stream.
My ffmpeg build supports vaapi hardware decoder.

...
AVCodec *pCodec = FindDecoder(AV_CODEC_ID_H264);
...

How to check am I using hardware decoder or not?

P.S. 
I have several ffmpeg builds with vaapi and without, But don`t see any difference in performance. Maybe cpu is very powerfull?
I am decoding two separate 1080p yuv420 streams in realtime.
