We can also create an RTSP server that uses some source of data like RTP or a file(WAV/MP3 for example) and allows RTSP clients to access it. gstrtpdec acts as a decoder that removes security from SRTP and SRTCP packets (encryption and authentication) and out RTP and RTCP. This works great overall but I’m seeing that as soon as add a new webrtcbin element to the pipeline, the video freezes for all users that are already connected to this pipeline until the peer for that new A gstreamer application is responsible for data manipulation, which may represent audio or video data, through the use of a pipeline. ramdau March 1, 2024, 5:41pm 1.

I don't even have a sample code to start with. The We discovered strange issue with one particular IP camera module: if we leave RTSP streams running for quite some time (for example for couple of hours, or overnight), it MAY produce very high video latency, like in terms of Tutorial 5. In such situation, GStreamer is used mainly for encoding and decoding of various audio and video formats. properties in the top level directory of the unpacked universal GStreamer Android binaries') GStreamer Discourse Problem with getting samples from pipeline on demand.
