[FFmpeg-user] Multicast to HLS, step by step

[Adrian .]

It's my understanding that hls uses the http protocol, probably best
to drop the multicast udp, and install a webserver.

ffmpeg -i vid.mp4 output.m3u8

will segment the mp4 and even write you a m3u8 file.

I usually set the list size to 0, so that I can have all my segments in 
the one m3u8,I am a lazy, lazy man.
I also enable caching with  -hls_allow_cache 1

ffmpeg  -i vid.mp4 -hls_list_size 0 -hls_allow_cache 1  output.m3u8

What I love best about ffmpeg and hls,
is how easy it is to add subtitles.
Here, I copy the codecs to avoid long transcoding times.


ffmpeg  -i vid.264  -i vid.aac  -i web.vtt \
-hls_list_size 0 -hls_allow_cache 1 -c copy output.m3u8


Pick one of the above, and place the ts files and m3u8 in your 
webservers directory so that it can be served via http.
If you add subtitles, include the .vtt and vtt.m3u8 files as well.
