(gst-rtsp-server) The media of factory attached to the mount point root path "\" can't be found

[Bruce Liang]

Hi,

Sorry for typo, it is “/”, not “\”.

I modified “test-appsrc.c” in “gst-rtsp-server/examples” to test if I can mount factory to root path “/”.

I changed line 127 from
  [gst_rtsp_mount_points_add_factory (mounts, "/test", factory);]
to
  [ gst_rtsp_mount_points_add_factory (mounts, "/", factory); ]

And when I use vlc to play the rtsp url, the SETUP response is “404 Not Found”.

It is tested under ubuntu18.04 and gstreamer version is 1.18.5.

Thanks,
Bruce Liang

Hi,

I’m trying to attach factory to the mount point with root path “\” and use vlc to play the rtsp url, but the SETUP response is “404 Not Found”.

Follow the document about [gst_rtsp_mount_points_add_factory]:
https://gstreamer.freedesktop.org/documentation/gst-rtsp-server/rtsp-mount-points.html?gi-language=c
“path is either of the form (/node)+ or the root path '/'.”
It seems that the root path is allowed.

Could someone tell me how to attach factory with root path “\” properly?
