Hi,
Does anyone have any examples of generating a HLS stream using fMP4
and byteranges with audio/video muxed into the same file (not separate
streams)?
I'm specifically trying to make it work with hls.js, a javascript
library using the media extensions
Doing some testing, I tried this:
ffmpeg -i $SRC -c:v h264 -hls_playlist_type vod -hls_flags
single_file -hls_segment_type fmp4 \
-c:a aac -ar 48000 -b:a 192k -crf 20 -g 48 -keyint_min 4 -b:v
2500k -maxrate 7400k -bufsize 3750k -sc_threshold 0 -hls_time 4
bbb-1080p.m3u8
That works with ffplay, but it still doesn't actually play with hls.js,
here is that stream:

But note, the apple reference implementation seems to play just fine, I
can't figure out what I did different:
https://dev.edman007.com/~edman007/pub/hls-bug/vids/prog_index.m3u8
And just some background, my target goal is to write a program that
manages security camera streams (an NVR), and does so with an HLS
interface, so I am actually planning on using libav* to make the audio
and generate the m3u8 myself. I'm actually getting the same results as
ffmpeg command (as shown above), so this is really to just identify the
problem and options I need to generate an appropriate mp4 to play in
this specific mode.
But no audio (as the Apple ref has it), and full length does work
https://dev.edman007.com/~edman007/pub/hls-bug/ff/h264-no-audio-full/bbb-1080p.m3u8
So what is going on that is messing things up when I add audio?
