this -segment_time 00:00:04 also not work.īut when I not use -codec: copy this command can work normal.įfmpeg -i file.mp4 -start_number 0 -hls_time 4 -hls_list_size 0 -f hls m3u8/file.m3u8. In the m3u8 file also is #EXTINF:8.341667. then I tryįfmpeg -i file.mp4 -force_key_frames 'expr:gte(t,n_forced*4)' -codec: copy -start_number 0 -hls_time 4 -hls_list_size 0 -f hls m3u8/file.m3u8.įfmpeg -i file.mp4 -codec: copy -map 0 -f segment -segment_list file.m3u8 -segment_time 00:00:04 file%03d.ts. this is my command.įfmpeg -i file.mp4 -codec: copy -start_number 0 -hls_time 4 -hls_list_size 0 -f hls m3u8/file.m3u8.īut in the m3u8 file always is #EXTINF:8.341667. Sorry.I read already.But still no answer why -hls_time 2 not work. Please, just read the docs? It's not that hard.

how to do can change ts time, for example 4s or shorter time. default every ts file time always it's 8s. It looks like it works and the different players I've tried play the output video correctly, but of course it feels suboptimal: it takes a lot of time and the use of concat seem to be very artificial.-codec: copy this is a very fast.

So I end up by using filter_complex with concat: ffmpeg -i in.mkv -filter_complex ' concat=n=1:v=1:a=1 ' -map '' -map '' -f hls out.m3u8 My guess is that there is something wrong with -c copy (but frankly I don't quite understand what I'm doing). My next idea was to first convert in.mkv to in_tmp.mkv with only one audio stream and then use the gist above: ffmpeg -i in.mkv -map 0:v:0 -map -0:a:0 -c copy in_tmp.mkvįfmpeg -i in_tmp.mkv -c copy -f hls out.m3u8īut the result was identical to my previous attempt.

I'm not sure why this solution doesn't work but depending on players and input files the video is not playing correctly (for example with hls.js the absence of the image is surrounded by only occasional sounds). I've then tried: ffmpeg -i in.mkv -map 0:v:0 -map -0:a:0 -c copy -f hls out.m3u8 I've tried different solutions with ffmpeg but non of them seem to be ideal.įor example ffmpeg -i in.mkv -codec: copy -f hls out.m3u8 from this gist works only if in.mkv has one audio stream (at least this is my understanding). I'm trying to convert some videos (in the different formats, e.g., mp4, mkv, avi) with multiple audio streams to HLS with only one audio.

Mp4 to hls
