VOXL-RTSP is a simple application to stream video from a VOXL image sensor using RTSP and, optionally, store video locally to a MP4 file. Run the video streaming application from the VOXL and view using a RTSP viewer such as VLC or Quicktime player.
The VOXL’s connectors are attached to the following Image Sensor Subsystem ports and have the following colloquial names.
|Port||Image Sensor ID||Colloquial Name|
|J2||0||Hi-res Image Sensor Port|
|J3||1||Stereo Image Sensor Port|
|J4||2||Tracking Image Sensor Port|
Run the streaming server on target, using the
-c option with the specified Image Sensor ID to choose which image sensor to stream video from.
