RTSP/RTP to HTTP/TS Gateway

[maersk]

Hi.

I was wondering if VLC can be setup as a gateway between a Darwin Streaming Server seving live H.264/AAC streams through RTSP requests and a player/stb requirering the stream encapsulated in MPEG-2 TS over HTTP progressive download.

The answer is yes, it can be done, but can it be done i a way where VLC does not decode and encode the streams ?
Ideally, VLC should "ONLY" handle RTSP protocol, strip off RTP headers and add TS headers and then make the stream available on its HTTP interface with PAT/PMT table added. Is this really possbile, just to use it as a transport container converter and protocol converter and not use the decode/encode part of it all ?

Kind regards

Yes. VLC will only decode the content as needed. If you use stream output, it will demux from RTP and remultiplex to TS, but it won't touch the elementary streams.

Hmm, rather cool.

Damn, VLC is good.

Now I just have to figure out how. Still compiling source for Linux.

Something like

vlc rtsp://someserver/somepath.sdp --sout 'std{access=http,mux=ts,dst=192.168.1.1:8000}'

Can it be that simple ? How does vlc in that case know that it only have to demux the rtsp/rtp streams and not also decode them ? I must have forgoten something.

Kind regards

If 192.168.1.1 is the server address. it is usually simpler to just put "dst=:8000".

VLC knows because you use the --sout option in the first place. Then it takes the elemetary streams straight out of the RTSP demuxer out to the "std" stream output module, which just connects the TS muxer with the HTTP network output. Note that this will only work if the elementary streams received from RTSP/RTP are supported by MPEG-TS.

Hi.

Something must be wrong in either the gateway end or the playing end. Well actually, maybe not, but something is missing though.

For the MPEG-4 part example I set things up in the gateway like this.

# vlc -vvv rtsp://192.168.1.1/test1.sdp --sout '#std{access=http,mux=ts,dst=:8100}' 2>&1 |tee log

In the other end, I just try to play http://192.168.1.2:8100, but the player says it awaits the VOL header.

Hmm, the VOL header is missing from the stream source to keep bandwidth down and because it is part of the description found in the test1.sdp and the player can play the rtsp stream directly. So in principle no need to include the VOL header in the rtsp based rtp stream.

Is there a way to tell the TS-muxer to add the VOL header to the stream at regular intervals ?

I assume the VOL header can not be added to the initial http header reply in any standardized way ....

(one more good argument to use RTSP

Kind regards

Peter

PS. Here is the output from the vlc rtsp2http gateway.

In my H.264 something else is apparently wrong.

In the RTSP2HTTP gateway end I have

#vlc -vvv rtsp://192.168.1.1/h264/test1.sdp --sout '#std{access=http,mux=ts,dst=:8100}' 2>&1 |tee log

Below is the output from the VLC gateway and from the client trying to play the http stream.
The client playing the http stream never really seem to get the stream. Anybody know why ?

Kind regards

Peter

Here the output from the vlc gateway

[maersk]

In the example above, I get the debug output below.

As seen, it identifies AAC audio and H264 video.
It finds the NAL_PPS. Its muxes audio with pid 68 and video with pid 69

Still it sends no data to a client connecting to it and it writes a lot of 'trying to send non-dated packet to stream output'

Anybody know why ? What does it mean ?

I can make the live rtsp stream available to people who want to test. Just ping me here or email me by sending private message via my profile here.

Kind regards

Peter

It is not implemented yet, and most likely will not be for a while."

That was status on Aug 2006, what is the status now?

[ph0t0n]

The error message "main stream output warning: trying to send non-dated packet to stream output!" (which I get myself on v0.8.6.f) seems to me to confirm that the state of things regarding h.264 is pretty much unchanged, as of current date.
