try this string
rtspsrc location=rtsp://username:password@10.10.10.100:554/Streaming/channels/101 latency=400 ! queue ! rtph265depay ! h265parse ! d3d11h265dec ! video.
where :554 is the standard RTSP port
and my CCTV camera stream is found under /Streaming/channels/101

Friends, I'm sending SRT from the IRL Pro app on Android to OBS (windows) with the Pipeline:
srtclientsrc uri=srt://:8000 ! tsdemux ! h265parse ! avdec_h265 ! video.
The video arrives normally, but I'm sending from two phones, but it's not synchronized. Is there any information missing in the pipeline so that the two videos are synchronized?
Thanks

Pretty sure this would be a very difficult task.. probably not possible.
If at all, use one source, put both sources in that pipeline and use GStreamer's compositor and arrange both streams. Eventually it does some syncing with the correct options.

Hello, how did you manage to do this synchronization? I've tried several ways, but I can't synchronize the 3 sources using Larix. Thank you.

Hi there
Firstly thank you for building and supporting this plugin, it's clear that it's bought a great deal of benefit to many people.
I've spent quite some time reading the posts of others, both here and across other platforms but have finally hit a blank and wondered if I might kinldy ask for help?
I have a Pi Zero 2W running GStreamer and have it streaming the onboard camera. The stream is being broadcast to a Windows PC on my network which I have also installed GStreamer on. I can view the Pi's video stream from the Windows PC using the following at the command prompt.
I can see the stream just fine, so I know both the PI and Windows PC are working correctly.
I have added the following to my PATH variable and have restarted the Windows PC
I have then added the plugin obs-gstreamer.dll to
When I launch OBS, I can't see GStreamer as an option under the source list. Looking at the OBS log file, I can see:
Now, I know my path variable is correct (I've tested this from the command prompt in a different directory to GStreamer so I'm at a loss as to why the plugin hasn't loaded.
Is there something obvious I've missed?
Thank you to anyone who might be able to provide help.
Kind regards,
ATH

You probably missed that MinGW part:
The prebuilt plugin is done with the MinGW SDK. If you wanted the MSVC one you would have to compile the plugin yourself with the MSVC SDK.

I apologise for needing to return and ask for more help, only I've hit another blocker having spent many hours reading docs and trying to debug things using ChatGPT.
In short, I am streaming from the PI using the following:
I can view that from the Windows PC (192.168.1.134) on port 5000 in a command prompt using
I've closed the command prompt and the live view down and have added a GStreamer source into OBS on the Windows PC using many different pipelines, each created myself following the docs, or suggested by ChatGPT when trying to debug. The one I have currently is as follows (this doesn't appear to generate any errors in the OBS logs).
In OBS, I can't see anything on the scene at all for the GStreamer plugin source, and I've tried to ensure that I've reset the scaling just incase the source was hidden somewhere (that said, when I select the source I can't see the red outline on the scene like I can for a couple of other sources I've added - such as a logo)
I've tried launching OBS from the command line using
And I've checked the current log for errors and can't see any GStreamer errors, with each source passing
So I'm now a bit stuck :D
I did try capturing the output window that's launched by the command prompt and whilst this works in OBS, the source seems to freeze once I end the RDP session that I'm using to access the Windows PC.
Should anybody have any ideas, I'd be very grateful. Thank you once again,
ATH

Windows debbuging is always a pain.
However you did not read the README about what you have to do.
You are not supposed to add an appsink yourself, but instead connect your raw image to a named element called "video".
So replace the appsink with "video.". There are quite a few examples in that README.

Thank you @Tuna this plugin is awesome.
I've successfully gotten it working to stream multiple IP security cameras video feeds with minimal latency (0.5 seconds) to my Windows OBS Studio instance with this pipeline command:
But for the life of me I can't seem to find a valid pipeline to also get the audio feed out of the stream. The cameras can put out AAC encoded or G.711 or G.711a encoded audio, and I've verified in VLC that the feed includes audio. The VLC player says the audio is mp4, but I'm not sure if it is already decoding and converting it when I inspect it there.
Every time I try to add an audio depay or audio parser or audio converter to the pipeline it seems to completely kill the feed and I lose even the video, and sometimes I lock-up OBS.
Here is one example of what I was trying that totally failed:
Any idea what I ought to be using instead?

Getting version 0.4.1 to work with MacOS, intel (at the end I'll put something about apple silicon)
I'm not sure this is the right place to put this so I apologize if it should go someplace else.
This version changed Gstreamer to be a .plugin. Previously, it was a .so. The version of .so we were running (really old) stopped working with OBS version probably 31 but it could have been 30.
According to something I read someplace here sticking the .plugin into /Library/Application Support/obs-studio/plugins/ should work like it did with the .so but at least for us it didn't.
We ended up having to stick the .plugin into the OBS app directly for it to be seen but then it was missing a whole bunch of libraries.
We haven't finished testing this (the cameras are in a church so we're not positive it'll fully work but we aren't getting any errors and it looks right.)
Steps (this mostly assumes you'll do the work in terminal and you know your way around the basic commands, e.g cp, mkdir, ln) it can be done with finder):

Steps (this mostly assumes you'll do the work in terminal and you know your way around the basic commands, e.g cp, mkdir, ln) it can be done with finder):
- Download the plugin https://github.com/fzwoch/obs-gstreamer/releases/tag/v0.4.1 (It's in the out-gstreamer.zip under MacOS)
- Download the Gstreamer for Mac pkg and install it. https://gstreamer.freedesktop.org/download/#macos. (This will install all the libraries in /Library/Framework)
- You will be modifying the OBS app (in Applications) so be sure to run any new versions of OBS before you add in the plugin, otherwise Mac with complain that it’s “damaged”.
- Make an /opt/local/lib directory if needed; by default you get an empty /opt. The plugin is looking here for the needed libraries. (It probably ought to be looking in /opt/local/lib/gstreamer or better yet the Framework but...)
- Copy the contents of /Library/Frameworks/GStreamer.framework/Versions/Current/lib to /opt/local/lib. (Alternately create a symlink)
- Copy obs-gstreamer.plugin to /Applications/OBS.app/Contents/PlugIns/

It is always recommended to compile your own version to the GStreamer SDK of your choice. The pre-built one is compiled to the SDK installed via macports. Copying other runtime files around may or may not work.
When compiling on your own the correct locations should be set in your final library. It will also build for the native architecture of your system (x86_64 or arm64).
