Re: [Live-devel] openRTSP with no backchannel

2009-09-02 Thread Ross Finlayson
I am working with a system that multicasts multiple streams over DVB-H. Normally, I receive an SDP file for each stream from the electronic service guide and I view the streams by passing the SDP file into my libav-based application. However, this did not work for any of the streams being generat

[Live-devel] RTSPClientSession and doEventLoop in a dynamic server

2009-09-02 Thread Rawling, Stuart
Hi, My implementation of a dynamic RTSPServer works as follows: When a request is received, the subclasses RTSPServer instance has an overloaded lookupServerMediaSession function. If the stream is not already present on the server, it will bootstrap the stream and add to the server before retur

Re: [Live-devel] multiple instances of live555 library

2009-09-02 Thread Ross Finlayson
The LiveMedia library uses the magical world of select(), which allows for monitoring multiple file handle descriptors (or in this case, sockets) to monitor for incoming/outgoing data. More precisely: The "LIVE555 Streaming Media" libraries use the (not so magical) world of events, whereby eve

Re: [Live-devel] live555 support for plain MPEG2-TS without RTP

2009-09-02 Thread Ross Finlayson
Does live555 support streaming content, in which the UDP payload contains just plain MPEG2-TS, without any RTP wrapper ? Yes. Looking into the testing programs that come with live555, most of them expect MPEG2-TS over RTP. I guess this is the reason, why I'm not able to play these streams in

[Live-devel] UDP framing in RTP

2009-09-02 Thread Michael Braitmaier

Answering my own question: The spec is Amendment 3: Transport of AVC video data over ITU-T Rec. H.222.0 | ISO/IEC 13818-1 stream. As usual its full of semantic changes of the original spec and not a streamlined spec ready to be implemented but at least it's a direction. AFAIK it says to grab th
