Hello Team,

I try to transcode videos based on the example :

But while trying to open some video files (not all), I have the following

[h264_vaapi @ 0xca3540] A hardware frames reference is required to
associate the encoding device.
Cannot open video encoder for stream #0

Those are my configure parameters :
            --extra-libs=-lalgolib\ -lpthread

I need your help please
