By using a defined config interval the rtp headers are sent every couple of For example, in your pipeline, you can clip, crop, transcode and merge audio video from different source using just Gstreamer in command line! In this article, we will explore how to create an RTSP (Real-Time Streaming Protocol) stream using GStreamer, with a focus on audiovisualization of audio. By using a defined config interval the rtp headers are sent every couple of seconds and therefore starting and stopping streams (senders and receivers) is possible anytime. Send mp3 audio file via UDP gstreamer. audioresample is useful for converting between different audio sample rates, similarly making sure that this example will work on any platform, since the audio sample rate produced by the audio decoder might not be one that the audio sink supports.
