[FFmpeg-user] HW acceleration and ffmpeg

[Harshil Makwana]

Hi,

You need to specify hardware accelerator to ffmpeg.

You can give hw acceleration name with 
-hwaccel option to ffmpeg.

And if you want to use it with any binary then its example code is located at :

doc/examples/hw_decode.c or doc/examples/vaapi_encode.c or
doc/examples/vaapi_decode.c file

You can compile and use its binary.

Thanks 
Harshil
