The qtiqmmfsrc plugin captures the video frames through Qualcomm Camera Service.
- [qtivcomposer](https://docs.qualcomm.com/doc/80-80021-50/topic/qtivcomposer.html)
The qtivcomposer plugin uses the GPU hardware to merge/mix several input video streams into a single output stream.
- [Waylandsink](https://docs.qualcomm.com/doc/80-80021-50/topic/waylandsink.html)
The waylandsink plugin uses the [GstVideoSink](https://gstreamer.freedesktop.org/documentation/video/gstvideosink.html?gi-language=c) GStreamer class. It's based on the Wayland [Weston](https://wayland.pages.freedesktop.org/weston/) compositor, which creates its own window and renders the incoming video frames in the window.
- [qtivsplit](https://docs.qualcomm.com/doc/80-80021-50/topic/qtivsplit.html)
The qtivsplit plugin uses the GPU hardware to split a single input video stream into multiple output streams. The number of streams is a user-defined variable and is equal to the number of source pads.
- [qtivtransform](https://docs.qualcomm.com/doc/80-80021-50/topic/qtivtransform.html)
The qtivtransform plugin uses GPU hardware to upscale/downscale, flip, rotate, crop, and color covert the incoming YUV or RGB video frames determined by the element properties.
- [qtisocketsink](https://docs.qualcomm.com/doc/80-80021-50/topic/qtisocketsink.html)
