Bug ID: 792804
Summary: gst_rtsp_mount_points_match does not match on a prefix
unless gint*matched !=NULL
Classification: Platform
Product: GStreamer
Version: 1.12.x
OS: Linux
Status: NEW
Severity: normal
Priority: Normal
Component: gst-rtsp-server
Assignee: gstreamer-***@lists.freedesktop.org

GNOME version: ---

I was trying to create an RTSP/HTTP proxy using the gst-rtsp-server framework.
I created a factory and tried to mount it on /proxy in hopes that I could serve
up media when a client connected to rtsp://localhost:8554/proxy/bigbuckbunny or
rtsp://localhost:8554/proxy/caminandes .

Unfortunately it appears that gst_rtsp_mount_points_match will not return the
factory for a partial match if the gint*matched parameter is NULL.

This happens to be the case when handle_describe_request() calls find_media().
Likewise handle_announce_request(). So while the factory might be usable in a
SETUP call, it causes a 404 for the media in a DESCRIBE RTSP request.

If it is important for the gst_rtsp_mount_points_match to return null for
prefix matches when matched==null (which appears to be the behavior described
in the API documentation), then I recommend you adjust handle_announce_request
and handle_describe_request to pass in a non-zero matched pointer.

experimental fix to make DESCRIBE and ANNOUNCE not malfunction

I am using the attached patch, but this allows the VLC session setup to proceed
further and hit other bugs (which I'm not sure are shortcomings in the
framework, or bugs in my code).
