Gstreamer multiple video streams Then i tried image/jpeg and it worked! Current command: I am using 1. change the rotation, and the one I'm working on combines multiple video streams (not looking at the audio yet) and produces a composite I'm going to accept your answer. I had already worked on separate left and right cameras using GStreamer. The way I expect them to behave is that the master clock should come from the audio pipeline and the video should follow it. I can stream 2 videos without a problem, but when I launch the 3rd gstreamer pipeline, all 3 videos become corrupted. Key Features of GStreamer: I want to learn more about synchronization of different streams with RTCP with Gstreamer. Streaming video in real-time using a gstreamer-rtsp server to a web page. So now we have an app that plays video streams with a custom Gstreamer pipeline that uses a HW-accelerated video sink. Unfortunately there is a documentation problem, particularly re: Windows and v1. The process is I run the script and the server is now active and then I can use the RTSP stream on another machine with my current machine IP. Source is a Axis camera. All three computers have their system clocks synchronized using NTP; Video computer gathers video and streams UDP to the Display computer; Audio computer gathers audio and also streams to the Display computer Yes, in order for webrtcbin to answer with sending two streams, the original offer must have two streams to receive. mp4 ! qtdemux ! h264parse ! nvh264dec ! glimagesink & gst-launch-1. Then I want to be able to stream two or more of those streams over webrtc and I want them to be in sync with each other. Notes: I use gst-rtsp-server for the RTSP server. avi. I was able to successfully generate a hsl stream with gstreamer, with the following code: gst-launch-1. splitmuxsink – Convenience bin that muxes incoming streams into multiple time/size limited As you want video and audio in your pipeline, it is going to be a little complicated (I thought a little pic might help): To keep the gst-launch command as clear as possible, I put each linear pipeline piece into one command line (the red connections in the first line, then the blue, the green and yellow ones and finally the queueing stuff which is colored black in the above picture): I wonder how I can capture video simultaneously with two cameras using gstreamer (or another tool)? I tried a bash script with two two gstreamer pipelines running at background (using ampersand). 0 -v \ videotestsrc is-live=true \ ! omxh264enc target-bitrate= python gstreamer play multiple video streams.
