# gst-meet: Integrate Jitsi Meet conferences with GStreamer pipelines
Note: gst-meet is in an **alpha** state and is under active development. The command-line options and the lib-gst-meet API are subject to change, and some important features (simulcast, RTX, TCC) are not yet fully functional.

gst-meet provides a library and tool for integrating Jitsi Meet conferences with GStreamer pipelines. You can pipe audio and video into a conference as a participant, and pipe out other participants' audio and video streams.
@ -42,7 +42,7 @@ You can pass two different pipeline fragments to gst-meet.
`--send-pipeline` is for sending audio and video. If it contains an element named `audio`, this audio will be streamed to the conference. The audio codec must be 48kHz Opus. If it contains an element named `video`, this video will be streamed to the conference. The video codec must match the codec passed to `--video-codec`, which is VP8 by default.
`--recv-pipeline-participant-template` is for receiving audio and video from other participants. This pipeline will be created once for each other participant in the conference. If it contains an element named `audio`, the participant's audio (48kHz Opus) will be sent to that element. If it contains an element named `video`, the participant's video (encoded with the codec selected by `--video-codec`) will be sent to that element. The strings `{jid}`, `{jid_user}`, `{participant_id}` and `{nick}` are replaced in the template with the participant's full JID, user part, MUC JID resource part (a.k.a. participant/occupant ID) and nickname respectively.
