 #### GStreamer and WebRTC
 
 GStreamer also supports reading streams with WebRTC/WHEP, although track codecs must be specified in advance through the `video-caps` and `audio-caps` parameters. Furthermore, if audio is not present, `audio-caps` must be set anyway and must point to a PCMU codec. For instance, the command for reading a video-only H264 stream is:

 To change the transport protocol, you have to tune the configuration of the client you are using to publish or read streams. In most clients, the default transport protocol is UDP.

-Binaries published in the [Releases](https://github.com/bluenviron/mediamtx/releases) section of GitHub are the output of a process which has been designed with a security-first approach. Every step from source code to the intended final destination of binaries is fully visible, immune from external interference and can be independently verified.
