[Live-devel] Live Streaming Device

[Pering, Trevor]

Hello -- I'm trying to follow the FAQ where it describes:

-- But what about the "testOnDemandRTSPServer" test program (for
streaming via unicast)? How can I modify it so that it takes input from
a live source instead of from a file?  

(Eventually I want to feed it from a H264 encoder, but for right now I'm
just feeding it a sequence of frames saved to files -- one file per
frame, which I generated from a working MPEG4 file streamer).

I'm having some trouble getting it working.  Basically, I can connect to
the server (from Quicktime), and it reads one frame from my source, then
it sits there for a while, and eventually says "Bad Request". Actually,
it reads the first frame twice (creates two sources for one request).
I've tried the same with the openRTSP test program (included below),
with the same results on the server side.

Any thoughts on where to start looking?  What would cause the system to
read one frame, but no more? I've poked around quite a bit but I can't
figure out why it's not going anywhere. Some things I've done that I'm
not sure about:

* I commented out most of the stuff in getAuxSDPLine(), so it just
returns NULL. This is because I don't have/undestand the stuff that this
function supplies.

* In my source, I just set fPresentationTime to gettimeofday when the
class is created, and increment it by a fixed time (100ms) for each
frame. Similar, fDurationInMicroseconds is fixed at 100ms.

* doGetNextFrame() just returns the frame immediately from the source
file. deliverFrame() is never called/used.

Thanks,
	Trevor
