Summary: Fatal error on failed preroll of one of streams
Classification: Platform
Product: GStreamer
Version: git master
OS: Linux
Status: NEW
Severity: major
Priority: Normal
Component: gst-rtsp-server

pcap dump

I have camera which tells on DESCRIBE that it has audio stream, but in fact it
is do not send any RTP packets of that SSRC. Using RTSP server to relay stream
fails due to "preroll failed" error and shuts down client connection.
I guess it is not correct behavior - instead of fatal fault it needs to
continue stream successfully prerolled streams.

This is an issue with rtspsrc not gst-rtsp-server, right?

gst-launch uridecodebin uri=rtsp://... ! autovideosink works pretty well.
gst-launch rtspsrc location=rtsp:// ! rtph264depay ! ... works good too.

As I see in rtsp-media.c:2120 status of media sets to ERROR state and returns
FALSE in wait_preroll. If I hack it to not return FALSE, rtsp-client.c:2108
can't create sdp.

I do not think it is issue in rtspsrc.

If I hack gst-rtsp-server in rtsp-media.c to return
GST_RTSP_MEDIA_STATUS_PREPARED instead of GST_RTSP_MEDIA_STATUS_ERROR in
timeout case, then rtsp-server drops client connection.

Yuuki, do you still have this issue with current gst-rtsp-server (1.12 or
master) ?
