B-frames

B-frames usually are not used for low latency streaming. Only use non-B-frames clip as the input.

# check B-frames
ffprobe -show_frames test.mp4 | grep "pict_type"

# transcode to non B-frames h264
ffmpeg -i test.mp4 -acodec copy -vcodec libx264 -x264opts bframes=0:ref=1 non-b-frames-test-h264.mp4

# transcode to non B-frames hevc
ffmpeg -i test.mp4 -acodec copy -vcodec libx265 -x265opts bframes=0:ref=1 non-b-frames-test-hevc.mp4
