[FFmpeg-devel] [PATCH] avformat/movenc: fix safari cannot play generated hls due to empty sdtp atom

[Jay Zhang]

This issue can be reproduced by command 'ffmpeg -i small_bunny_1080p_60fps.mp4 -an  -c:v libx265 -tag:v hvc1 -f hls -hls_segment_type fmp4  out.m3u8'. After remove the empty sdtp atom, safari can play the out.m3u8 properly.
