hevc_videotoolbox does write b-frames, but h264_videotoolbox does not.
Steps:
1. Encode a video with h264_videotoolbox
$ ffmpeg -i input.foo -acodec copy -vcodec h264_videotoolbox -b:v 20000k
-profile:v main /ffmpeg_output.mp4
2. check the video for b-frames
$ ffprobe -show_frames ffmpeg_output.mp4 > outputfile.txt
In outputfile.txt there is pict_type=P and pict_type=I only, there is no
pict_type=B
Full output is attached.
