I am trying to re-encode a set of mp4 files (a mix of 1080p and 720p, all at 30FPS) to HLS with constant bit and frame rates. I also need a 29.97 frame rate, CABAC/2 and fixed 6.006 sec ts segments.
I have experimented with a lot of options, so the ffmpeg string I am using is probably both inefficient and hideous AND I can’t achieve the desired result. I’m trying to use max rate and min rate to hold the bitrate at 2M and fps=fps=29.97 to make the frame rate constant. Here is my current ffmpeg string: /usr/bin/ffmpeg -i "$SOURCE" \ -profile:v high -level 3.1 -s 1280x720 -filter:v fps=fps=29.97 \ -strict -2 -c:a aac -c:v libx264 -g 60 -keyint_min 60 -force_key_frames "expr:gte(t,n_forced*2)" \ -f segment -segment_list_type m3u8 -segment_list_size 0 -segment_time 6.06 -segment_time_delta 0.1 \ -b:v 2M -maxrate 2.0M -minrate 2.0M -bufsize 3M \ -ar 48000 -start_number 0 \ -hls_time 6 -hls_list_size 0 -f hls \ -hls_base_url "$BASEURL" \ -hls_segment_filename "video%04d.ts" \ -strict -2 -threads 8 “video.m3u8" I am running this on centos 7 and my ffmpeg version is 3.4.7. Any advice on how to clean this up and achieve the desired results would be greatly appreciated.
