[FFmpeg-user] H264 VAAPI Encoder

[Armin K.]

Hi everyone,

I noticed that recently a VAAPI based H264 encoder was added to ffmpeg.
I built ffmpeg from git and now I have h264_vaapi listed in ffmpeg -encoders
output.

However, when I try to use ffmpeg ... -vcodec h264_vaapi I get the following
error:

Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto-inserted scaler 0'

The command I use is:

ffmpeg -hwaccel vaapi -i <inputfile> -vcodec h264_vaapi <outfile>.mkv

I'm trying this on Intel Skylake GT2 HW on Linux x86_64, using libva and
libva-intel driver from git master in combination with linux 4.6.0-rc7.

Can anyone assist here?

Thanks!
