Send UPSTREAM GstForceKeyUnit to rtspsrc in Gstreamer pipeline - c++

I want to be able to request my RTSP server (gst-rtsp-server) for sending an h264 keyframe from the client side (rtspsrc). From the docs it should be possible but I couldn't get it to work.
Can anyone share a short snippet for how it's done?
Thank you

Query Gstreamer rtsp methods, like PLAY, DESCRIBE etc

I can't figure out how to call rtsp methods with headers, for understanding:
I have an rtsp player on qt, I want to add the rtsp playback speed functionality, many vendors do this by sending a PLAY request with a Speed header,
but I don't understand how I can send this request from gstreamer.
You set playback rate for the pipeline via a GstSegemnt. E.g. when issueing a seek command. See https://gstreamer.freedesktop.org/documentation/gstreamer/gstsegment.html#GstSegment.
rtspsrc should then take care of sending the required header info to the RTSP server when initiating the session.

GStreamer: Intercept End of Stream Event and restart

I'm implementing an RTSP server which reads a video H264 file stream and makes it available under RTSP protocol.
The idea is this:
The server creates a pipeline using video1.mp4 as videosrc and then, when video ends and the EOS event is generated, it has to switch filesrc to video2.mp4 and restart streaming automatically. When video2.mp4 ends it switches back to video1.mp4 again. The client is supposed to never stop receiving a video stream in this way.
Is it possible to obtain a server behavior like this?
Cheers

Gstreamer rtspsrc proxy mem alloc error

Hey Guys
I have one ubuntu machine with gstreamer version 1.8.3 and one arm device with gstreamer version 1.4.4, if I try to use the rtspsrc proxy setting on an gst-launch. I have the same mem allocation error on both devices.
I want to test if is possible to play the axis camera stream over an HTTP tunnel that is described in the axis camera manual as:
RTSP can be tunnelled over HTTP. This might prove necessary in order
to pass firewalls etc. To tunnel RTSP over HTTP, two sessions are set
up; one GET (for command replies and stream data) and one POST (for
commands). RTSP commands sent on the POST connection are base64
encoded, but the replies on the GET connection are in plain text. To
bind the two sessions together the Axis product needs a unique ID
(conveyed in the x-sessioncookie header). The GET and POST requests
are accepted on both the HTTP port (default 80) and the RTSP server
port (default 554).
I see at the rtspsrc there is a proxy settings for HTTP tunneling, i dont know if it works, or if I am on the wrong way.
To get forward on this task i would testing this proxy propertie, but if i start the gst-launch I have this mem alloc error.
Pipeline:
gst-launch-1.0 rtspsrc location="rtsp://root:1qay2wsx#192.168.1.211/axis-media/media.amp" proxy="http://root:1qay2wsx#192.168.1.211/axis-media/media.amp" ! rtph264depay! h264parse ! decodebin ! autovideosink
Error:
(gst-launch-1.0:15450): GLib-ERROR **: /build/glib2.0-prJhLS/glib2.0-2.48.2/./glib/gmem.c:100: failed to allocate 18446744073709551614 bytes
I hope anybody can help me, and thanks for your help guys.

Receive rtsp stream using gstreamer

I want to receive rtsp stream using gstreamer I knw rtspsrc can be used for this purpose but the problem is that it only receives it as a client but in my case i have a ffmpeg application which streams the video as a client and waits for a server to connect with it before streaming. So i want gstreamer to act as server and receive the stream from ffmpeg
I haven't used it myself, but I believe there is a separate package for RTSP server functionality. In Debian based systems it should be under something like:
libgstrtspserver-0.10-0

How to make a streaming relay using gstreamer?

I would like to make of some sort of a streaming server. I would like it to receive RTSP streams over the net from live streams (e.g. webcam, ipcam, etc.) then broadcast that same stream on my local network using a different URL. I know gstreamer can do it quite well but I don't know how. I'm quite confused with the way the documentation is written. Can somebody help me?
If you would like to retransmit the video streams using RTSP as well, you can use GStreamer RTSP Server. There is a lot of examples on the Internet how to use it. The best source of the examples is the gst-rtsp-server's examples directory:
http://cgit.freedesktop.org/gstreamer/gst-rtsp-server/tree/examples
As you want to retransmit existing RTSP streams, you'll need to use the rtspsrc element for reception of the remote streams.
I think you are looking for something like this: https://github.com/jayridge/rtsprelay. It configures one rtsp server to receive clients on two urls with a record link and a play link.
This example uses a dynamic form:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1454
rtsp://server/path?uri=encoded-URI
you HTML encode the destination in URI form and add a path where it should register this camera to. The first time you connect; it will take some time, after that; the sessions are re-used.
