FFmpeg command to convert MP4 to HLS ABS formats for streaming
This is a follow up of this article. The difference between the two is that this article will show you how to use one command for FFmpeg that will create a collection of video fragments that combined will be your static HLS stream with support for ABS (Adaptive Bit-rate Streaming).
Of course, you will need to replace INPUTFILENAME in the example below with the file name of your mp4 that you want to have available in HLS format.
ffmpeg -hide_banner -y -i INPUTFILENAME.mp4 \ -vf scale=w=640:h=360:force_original_aspect_ratio=decrease \ -c:a aac -ar 48000 -c:v h264 -profile:v main \ -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod -b:v 800k -maxrate 856k \ -bufsize 1200k -b:a 96k -hls_segment_filename OUTPUT/360p_%03d.ts OUTPUT/360p.m3u8 \ -vf scale=w=842:h=480:force_original_aspect_ratio=decrease \ -c:a aac -ar 48000 -c:v h264 -profile:v main \ -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod -b:v 1400k -maxrate 1498k \ -bufsize 2100k -b:a 128k -hls_segment_filename OUTPUT/480p_%03d.ts OUTPUT/480p.m3u8 \ -vf scale=w=1280:h=720:force_original_aspect_ratio=decrease \ -c:a aac -ar 48000 -c:v h264 -profile:v main \ -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 -hls_playlist_type vod -b:v 2800k -maxrate 2996k \ -bufsize 4200k -b:a 128k -hls_segment_filename OUTPUT/720p_%03d.ts OUTPUT/720p.m3u8 \ -vf scale=w=1920:h=1080:force_original_aspect_ratio=decrease \ -c:a aac -ar 48000 -c:v h264 -profile:v main \ -crf 20 -sc_threshold 0 -g 48 -keyint_min 48 -hls_time 4 \ -hls_playlist_type vod -b:v 5000k -maxrate 5350k \ -bufsize 7500k -b:a 192k -hls_segment_filename OUTPUT/1080p_%03d.ts OUTPUT/1080p.m3u8
