-To enable virtual output set "virtual" property in core section
-to desirable number of virtual outputs. Then add settings to
-each virtual output in output sections. Name of the outputs
-will be virtual1, virtual2... etc.

-Subject: [PATCH 2/3] Add gst-recorder for h264 output streaming
-
-Following patch ported to Weston 1.11 with minor updates
---------
-To use gst-recorder run weston with arg --gst-record. Add
-recorder=true property to output section of one of the outputs
-(real or virtual). Use properties ip, port to set host of RTP
-stream. Use property bitrate to set desirable maximum h264 bitrate.

-Subject: [PATCH 3/4] gst-recorder: Use USERPTR instead of DMABUF for VSP
- output
-
-The RCar-Gen3 encoder requires buffers to be allocated and managed
-externally when using dmabuf buffers.  Since different sized buffers
-are required for each output, the VSP cannot allocate these buffers
-externally.  The encoder provides its own buffers in USERPTR mode, so
-switch to that.
