[FFmpeg-user] how to enable hardware acceleration in ffmpeg

[Yogesh Tyagi]

Hi,

Is there any command line option in ffmpeg to enable hardware acceleration
for h264 decoding.I have configured and compiled ffmpeg with"
--enable-vaapi --enable-hwaccel=h264_vaapi" options but ffmpeg is not
invoking  decode_slice function of vaapi_h264.c.



Thanks and Regards,
Yogesh
