I'm trying to do the vaapi/d3d11va/videotoolbox hardware accel for
AV_CODEC_ID_H264. I'm following the libav example, but when I init it gives
me "requires waccel initialisation" although I am creating the hw device w/
av_hwdevice_ctx_create. What am I missing?

Format videotoolbox_vld chosen by get_format().

Error found

Format videotoolbox_vld requires hwaccel initialisation.
