+Capture the raw device data. Default is 0.
+Using this option may result in receiving the underlying data delivered to the AVFoundation framework. E.g. for muxed devices that sends raw DV data to the framework (like tape-based camcorders), setting this option to false results in extracted video frames captured in the designated pixel format only. Setting this option to true results in receiving the raw DV stream untouched.

-The libndi_newtek input device provides capture capabilities for using NDI (Network
-Device Interface, standard created by NewTek).
-
-Input filename is a NDI source name that could be found by sending -find_sources 1
-to command line - it has no specific syntax but human-readable formatted.
