No, changing resolution would require re-encoding the file.

I was looking for a code to convert video files in a directory where it has multiple subfolder for each video file. I want to run a batch code so it can convert the video files and save them where the original file was there.

Example:

Main folder : Movies

---> Subfolder1 : movie1.mp4

---> subfolder2 : movie2.mp4

---> subfolder3 : movie3.mkv

And so on.

I want the output to be same as the my main structure but in . m3u8 format.

I have used a code where it can convert each movie manually but for some reason I can use the .m3u8 file or link only in that server i can't make it work all over the internet.

for i in .mp4; do ffmpeg -i "$i" -c copy -map 0 -hls_time 3 -hls_list_size 0 -f hls "${i%.}.hls"; done

Thanks

In short: If you need to ask, there won't be any.

In long: m3u8 is a HLS Index and widely used for streaming. E.g. transfering the least data possible to provide what is necessary for playback. Though I really do not understand how you didn't get that as literally a first google result... - https://en.wikipedia.org/wiki/HTTP_Live_Streaming

-codec: copy this is a very fast .but -hls_time not working. default every ts file time always it's 8s. how to do can change ts time, for example 4s or shorter time.

Please, just read the docs? It's not that hard.

sorry.I read already.But still no answer why -hls_time 2 not work. this is my command.

ffmpeg -i file.mp4 -codec: copy -start_number 0 -hls_time 4 -hls_list_size 0 -f hls m3u8/file.m3u8.
but in the m3u8 file always is #EXTINF:8.341667. then I try
ffmpeg -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.
Same result.

then I use other command.
ffmpeg -i file.mp4 -codec: copy -map 0 -f segment -segment_list file.m3u8 -segment_time 00:00:04 file%03d.ts.
in the m3u8 file also is #EXTINF:8.341667. this -segment_time 00:00:04 also not work.

but when I not use -codec: copy this command can work normal.
ffmpeg -i file.mp4 -start_number 0 -hls_time 4 -hls_list_size 0 -f hls m3u8/file.m3u8. or
ffmpeg -i file.mp4 -map 0 -f segment -segment_list file.m3u8 -segment_time 00:00:04 file%03d.ts.
in the m3u8 file #EXTINF:4.004000. time change already. but it's very slow not with -codec: copy.

I don't why -codec: copy can't use -segment_time or -hls_time?
if anyone have answer plases tell me.

Thanks for good experience.

After conversion, It works good in Safari , but not in Chrome.

Is this Chrome's bug ?
