Hi all, I encoded a raw YUV video once with h264_vaapi and once with libx264 codec. The output of h264_vaapi is about 4.8 MB, while the output of libx264 is 1.1 MB.
Here is the commands: ffmpeg -loglevel trace -vaapi_device /dev/dri/renderD128 -video_size 1920x1080 -i raw_1080.yuv -vf 'format=nv12,hwupload' -vcodec h264_vaapi out_h264_vaapi.mp4 ffmpeg -loglevel trace -video_size 1920x1080 -i raw_1080.yuv -vcodec libx264 out_libx264.mp4 Is this variation in output size normal? or should I tune some settings?
