The format is a derivative of the Apple Quicktime file format, so Bento4 can be used to read and write most Quicktime files as well. This format is defined in international specifications ISO/IEC 14496-12, 1. but it's very slow not with -codec: copy.Welcome to Bento4 ¶ Bento4 MP4, DASH, HLS, CMAF SDK and Tools ¶Ī fast, modern, open source C++ toolkit for all your MP4 and DASH/HLS/CMAF media format needs.īento4 is a C++ class library and tools designed to read and write ISO-MP4 files.

orįfmpeg -i file.mp4 -map 0 -f segment -segment_list file.m3u8 -segment_time 00:00:04 file%03d.ts. 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.
