  • Test tool for snb h264 encoder in libva git

    About 1 week ago there was this commit:

    http://cgit.freedesktop.org/libva/co...f402d1ee85a8c1

    It adds that new tool:

    $ avcenc
    Usage: avcenc <width> <height> <input_yuvfile> <output_avcfile> [qp]

    Can be tested with

    http://kanotix.com/files/fix/mplayer-vaapi-latest.txt

    I currently just put every test binary in the vainfo package as hack. Now i want to see some results...

    One Kanotix user did a few tests for me, maybe somebody finds that interesting (avcenc defaults to qp 26):
    Code:
    $ avcenc 1920 1080 video.yuv video.h264
    libva: libva version 0.32.0
    libva: va_getDriverName() returns 0
    libva: Trying to open /usr/lib/dri/i965_drv_video.so
    libva: va_openDriver() returns 0
     213/213 ...
    done!
