# qtirtspbin

The qtirtspbin plugin transmits the video or data streams using RTSP.

The plugin can transmit the encoded video, text data (ML data), or serialized data (x-rtp packet).

When the plugin starts, it opens a default port such as *127.0.0.1:8900* where many clients (media players such as VLC) can connect.
