[Libav-user] Error running av_hwdevice_ctx_create: ENOMEM

I am trying to perform h264 video encoding on a GPU using the ffmpeg's vaapi library.

I have been following this this example from ffmpeg Github repo: https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/vaapi_encode.c

I installed ffmpeg with –enable-vaapi, but whenever I try to run av_hwdevice_ctx_create, it returns -12 error which maps to an out of memory message. I am also unable to successfully run avcodec_find_encoder(AV_CODEC_ID_H264), that just returns NULL.

I created a stack overflow post with more details about it:
What am I possibly be missing here?
