Hi,

How to add some ffmpeg muxer options to vlc's transcode ? I think I need the muxer to produce a "mp4 fragmented file", i.e. metadata stored every now and then instead of just once at the beginning/end of the file, suitable for H.264 streaming.

Situation:

I am trying to stream a RTSP webcam stream to a web/flash player (jplayer, flowplayer, jwplayer). I had success with jwplayer and flowplayer using FLV1 codec. (I do get some vbv buffer overflow errros, but I can live with that.)
I would like to try to make this work with the H.264 codec. The web/flash players can't take my H.264 stream no matter how hard I try, something like this never works, using either flv or mov muxer..
The movflags=keyframe option I got from an outdated ffmpeg documentation is unknown.

What are the logs?

Hi Guys,
Have you made any progress on this at all? I am trying to do exactly the same as you. I have an IP camera RTSP stream that I want to transcode and serve via HTTP for use with jwplayer.

You mentioned that you had success using FLV1 codec. Even that would be acceptable for me, but I can't get that to work at all either. With VLC 2.1, it simply tells me that "cannot find video encoder (module:any fourcc:FLV1)".

With 2.0.3 I get the following:
[020f80c0] main stream output debug: using sout chain=`standard{mux="",access="'#transcode{threads=2,vcodec=FLV1,vb=2000}",dst="standard{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=0.0.0.0:8001/townhall.flv}'"}'

[020d0fd8] main stream out debug: destroying chain done

I would be ecstatic to be able to use h264, but flv would be fine for now. Any help would be greatly appreciated!

Did you read your own log? Quoting is obviously wrong.
