But if you don't need your pipeline to run while there are no clients connected you shouldn't need to do this. You are also probably going to run into issues with blocking your pipeline, so you might need to dynamically connect your pipeline via blocking probes to the intervideosink, or use a valve, or use a leaky queue.

I am trying to use gstreamer to simultaneously stream a video source via RTSP and record it and in the future, more parallel processes. My main problem with the gst-rtsp-server examples is that the RTSP component wants to control the whole pipeline, and I don't want it to impact one of the other branches.

My approach to this problem I would be happy to hear a simpler way is to use a primary, always-running pipeline which branches to an appsink, and allow the RTSP server to create its own pipeline using an appsrc, which I connect to the appsink in the GstRtspMediaFactory's "media-configured" signal handler. For the purposes of example, my "main" pipeline can be "videotestsrc! In this case, it works, that is to say I can connect a media player to the RTSP stream and see the test image, although the memory usage explodes uncontrollably quite quickly.

If I move the xenc element to the "main" pipeline, which I want to do so it can be shared between the parallel functions, I never see any picture, and gst-play reports "Could not receive any udp packets". I checked that the RTSP pipeline's clock is slaved to the main pipeline clock this seemed to happen automaticallybut I guess I have some synchronization issues.

Perhaps that can explain the memory explosion when passing raw packets too? Since assumedly the appsink is receiving frames much more quickly than the appsrc can send them onwards. I pasted a short code listing at pastebin.

Hi all, I am trying to use gstreamer to simultaneously stream a video source via RTSP and record it and in the future, more parallel processes.

Any ideas? Free forum by Nabble. Edit this page.Gstreamer is a tool for manipulating video streams. The purposes I have used it for is mainly to stream video in real time over a local area IP network.

Doing that I found a lack of basic tutorials on how to do that using the command line. This tutorial covers the basics of live streaming. To read or write files will not be covered, though the basics of that is easy following the same principles as broadcasting the streams. If you want to see a comparison of the real time capabilities of the streams, that is a post coming soon. If you cannot distinguish between the original and the copy, it passes. Gstreamer consists of several command line applications.

In this tutorial we focus on two of them: gst-launch The main part of the tutorial covers how that is done. Gstreamer is constructed using a pipes and filter architecture. The pipes and filters can be added to each other much like unix pipelines but within the scope of gstreamer. The basic structure of a stream pipeline is that you start with a stream source camera, screengrab, file etc and end with a stream sink screen window, file, network etc.

The entire system of pads and filters is called a pipeline. This stream launches the video test source and pipes it to the screen. Autovideosink is a useful abstraction.

Use that. Gstreamer has a filter called capabilities, caps for short. That changes some properties of the stream. What properties can be set depends on the type of stream. To start manipulating your stream, one of the first things you might want to do is change the properties of the raw stream. The following example changes the resolution to x pixels.

This step assumes you have a working camera attached to your system. The suorce for the linux camera is v4l2src.

This could actually fail depending on your cameras aspect ratio. I will come back to that later. Autovideosink is much more easy to get working, and is by that quite useful to debug your pipelines. For my purpose I wanted to use either a camera or a portion of the screen as a source.

Gstreamer has screengrabbers. If you are on Linux it is ximagesrc, on windows it is XXX.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. The dark mode beta is finally here.

Probably encoding and decoding consume a lot of processing power. As we have a fancy Logitech C, of course we want to directly stream camera encoded H.

This does work with gstreamer There's no pre-compiled version available, so this needs to be compiled from source. Be careful : After compilation, it turned out to be pretty experimental stuff.

It hung the system, the first time I tried it. The filesystem was destroyed to an unrecoverable extent, see also issue 3.

VLC complains about pictures maybe being too late to be displayed and picture IS to late to be displayed, which is consistent with choppy rendering. My code putting data into the app src is scanning the input video stream and breaking it into NAL units. So for 5FPS, the timestamps would go 0, ms, ms, ms,ms, etc.

This algorithm gives us the ability to clearly organize the video data into frames to be played back at a given framerate. In my encoding, each NAL unit I and P frames only is a frame, emitted by my camera at the defined frame rate. When monitoring the packet flow in Wireshark, I see packets stop flowing from my stream to the VLC player for milliseconds. VLC is griping about packets being late almost non-stop, and my video is choppy.

I have the same problem whether I run my camera at 10fps or 5fps. I am looking for some hints for how to determine where this bottleneck is. I need to determine if the problem is indeed in GStreamer or is in the network layer. Kerry Calvert. Manager Software Engineering. MicroPower Technologies Inc.

I then went to wireshark and came up with some very interesting results.Search everywhere only in this topic. Advanced Search. Classic List Threaded. The rtpjitterbuffer does not work. The stream randomly fails afer a while with "rtphdepay0: NAL unit type 26 not supported yet" Whereas the number is different in each run.

Before hand the debug info "rtphdepay0: Could not decode stream. May guess is that the mtu is not set correctly for the payloader at the server side. A look in wireshark gave that some packets have sometimes a size are above Bytes.

This should not be the case since the payloader has a default mtu of Bytes. What can i do let it decode the stream correctly? I thought the gst buffers or rtp packets should just be put in the tcp data block. Re: h. That is not true. Does anybody has an idea on how to stream h. In reply to this post by pfarmer. Thanks a lot for the reply!

How can I do this? Chuck Crisler Tim, how does the -v option work on gst-launch? I haven't seen anything that seems to relate to that in the elements I have worked with but I know that it generates output that otherwise isn't displayed. If only you had the source code to check, right? Thank you. From my perspective, GStreamer is a rather large and intimidating project. It takes some time to get familiar with all of the various pieces and understand what they are doing. Sometimes a short explanation like this helps me get started digging to really understand.

Again, Thank you. Pass -v to gst-launch If it's avc, add an Search everywhere only in this topic Advanced Search h. I somehow should to say to the piple to be live which does not need to preroll.

But well its somewhat in a roundabout way and has quiet some overhead. Is it normal that there must be no tsparse before the tsdemux? Somehow I have the feeling I was struggling with that already one year ago :. Actually I am not sure what does avc stand for in this case.
