@item -capture_mouse_clicks
Capture the screen mouse clicks. Default is 0.
+@item -capture_raw_data
+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.

Sets the video input source. Must be @samp{unset}, @samp{sdi}, @samp{hdmi},
@item timestamp_align
Capture start time alignment in seconds. If set to nonzero, input frames are
dropped till the system timestamp aligns with configured value.
-Alignment difference of upto one frame duration is tolerated.
+Alignment difference of up to one frame duration is tolerated.
This is useful for maintaining input synchronization across N different
hardware devices deployed for 'N-way' redundancy. The system time of different
hardware devices should be synchronized with protocols such as NTP or PTP,

Defaults to @samp{0}.
+@item wait_for_tc (@emph{bool})
+Drop frames till a frame with timecode is received. Sometimes serial timecode
+isn't received with the first input frame. If that happens, the stored stream
+timecode will be inaccurate. If this option is set to @option{true}, input frames
+are dropped till a frame with timecode is received.
+Option @var{timecode_format} must be specified.

+
+@item enable_klv(@emph{bool})
+If set to @option{true}, extracts KLV data from VANC and outputs KLV packets.
+KLV VANC packets are joined based on MID and PSC fields and aggregated into
