[FFmpeg-user] help with live streaming with ffserver

Mon May 4 06:28:49 CEST 2015

Hello,

I've written a couple of messages last couple of days, and I'd say for now
ignore them.

I've been doing a lot of testing with many different configurations and
honestly I'm pretty lost on how to get this working...

I'm running a simple test... I'm simulating a live stream by reading a file
with ffmpeg and feeding it to ffserver. The file I have is mp4 with h264
and aac.

I want to be able to play it within an HTML5 <video> object by accessing
via http from ffserver.

So my first question... is this even possible, within <video> object and
http?

What would be the appropriate ffserver config and ffmpeg command line?

My current command line to feed ffserver is:

$ ffmpeg -re -i sample.mp4 -c copy  http://localhost:8090/feed1.ffm

I won't provide the ffserver <Stream> config because honestly I've tried
quite a few and none worked... so I'm reaching out for help to see which
one would work given that I'm trying to maintain the original audio and
video codecs to play back via HTML5.

Again, is this doable with ffserver and HTML5? All the combinations I
tried, the HTML5 video window simply returned "No video with supported
format and MIME type found"

If it is possible to do this in HTML5 <video> what would the appropriate
ffserver config be?

If not possible then do I need to use a player like flowplayer?

Any help is appreciated.

thank you
Ricardo
