RTSP Server Examples

[Sean McNamara-4]

Hello,

 I am using latest git gst-core, gst-p-base, gst-p-good, gst-p-bad,
gst-p-ugly, gst-rtsp-server. I am using libtheora 1.0 and libogg 1.1.
I created a file test.ogg with this pipeline:

videotestsrc blocksize=4096 num-buffers=200 ! ffmpegcolorspace !
theoraenc ! oggmux ! filesink location=~/test.ogg

This pipeline works fine:

playbin2 uri=file://${HOME}/test.ogg

However, if I start the gst-rtsp-server example "test-ogg" and point
it to the same file, this pipeline causes a critical assertion in the
RTSP server when trying to connect using the following pipeline:

playbin2 uri=rtsp://localhost:8554/test

The full output on the server side:

$ ./test-ogg.bin ~/test.ogg

The critical assertion is this:

The offending line of code is

The interesting thing is: if I comment out lines 417 and 418, then
(frame >= keyframe) is TRUE, and the critical doesn't trigger.
Unfortunately, after "fixing" this, I still don't get any output --
and I get no further error-ish stuff, only debug info.

The test-mp4 and test-readme examples don't work either. I don't know
how to operate this code, as it seems determined to do nothing
regardless of my efforts. I have also tried VLC as an RTSP client to
see if it's the client-side, but that hangs just like the gstreamer
client. I tried using VLC as an RTSP server, and both gstreamer and
VLC can connect to it and stream the very same Ogg/Theora test file.
Maybe I am making a user error - would anyone care to enlighten me?

Thanks,

Sean
