rtsp-server | Lightweight RTSP/RTP streaming media server | Video Utils library

The rtsp server uses TCP because your client query asked for that using rtspt where last t queries for TCP transport. Just using rstp instead should use UDP. You may have a look to protocols property of rtspsrc for more details.

Full story is in the comments here and continued to solution here: Gstreamer Android HW accelerated H.264 encoding

It looks like you're on windows, and you don't have any compilers in your path. IF you're wanting to use the Visual Studio compiler (cl), then the easiest way is to open the Visual Studio command prompt, and run Meson from there (I think that the forthcoming meson 0.60 will have an option to discover cl.exe automatically). Other compiler options on Windows are gcc or clang from msys or the older intel icl compiler (not the new oneAPI one)

As the documentation notes, always use a queue after each tee branch:

https://gstreamer.freedesktop.org/documentation/coreelements/tee.html?gi-language=c

One needs to use separate queue elements (or a multiqueue) in each branch to provide separate threads for each branch. Otherwise a blocked dataflow in one branch would stall the other branches.

In your particular case, you should also add the tune=zerolatency option to the x264enc element. That is because the latency of x264enc by default is higher than the default queue sizes. Alternatively you need to increase the queue sizes to compensate for x264enc's latency.

You have two different files: a .bb and a .bbappend.

A .bb is the base recipe of one (or multiple) packages. It generally describe how to fetch, configure, compile, install files in a package for your target.

A .bbappend file is an 'append' file. It allows a meta (here meta-petalinux) to modify an existing recipe in another meta without copying it. A .bbappend can modify any steps of the bb file: source fetch, configure, compile, install...

You can for example create your own bbappend of Gstreamer, to enable pango (disbaled by default on my Yocto). The bbappend filename is gstreamer1.0-plugins-base_%.bbappend and only contains PACKAGECONFIG_append = "pango"

The Yocto Manual can give you more information on bbappend files here.

This error is an error for a reason, as it likely means that you are doing something wrong: when a stream returns Poll::Ready(None), it means that the stream is completed (in a similar fashion to Iterator, as has been commented).

However, if you are still sure that this is what you want to do, then you can call stream.fuse() in order to silence the error and simply return Poll::Ready(None) forever.

The extra single quotation marks in the pipeline caused the problem. So a working pipeline would be:

It refers to to the crate currently being compiled. So in this example, it is resolved as rtsp_server::body::Body. The body::Body part is refering to the Body struct/enum of the body module.

The Rust documentation says:

crate is also used to represent the absolute path of a module, where crate refers to the root of the current crate. For instance, crate::foo::bar refers to the name bar inside the module foo, from anywhere else in the same crate.

Well, I found that this one works:

What version of GStreamer do you have installed? According to the documentation gst_rtsp_media_factory_set_enable_rtcp() is introduced with GStreamer 1.20 which has not yet been released.
