Instruction Manual - NMX-ENC H.264 Encoder
Requests the input format of the video port addressed by the D:P:S.
NOTE: Queries sent to port 2 will not receive a response from the encoder. All queries should be sent
to port 1.
Syntax:
SEND_COMMAND <DEV>, "'?VIDIN_FORMAT'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDIN_FORMAT'"
Returns a COMMAND string of the form: VIDIN_FORMAT-<format>.
Sets the input format of the video port addressed by the D:P:S to <format>.
Syntax:
SEND_COMMAND <DEV>, "'VIDIN_FORMAT-<format>'"
Variables:
format = SDI, HDMI, DVI, S-VIDEO, COMPONENT, COMPOSITE, VGA for Multi-Format inputs.
Example:
SEND_COMMAND VIDEO_INPUT_1,"'VIDIN_FORMAT-COMPONENT'"
Sets the format of video input port (#1 based on D:P:S) to COMPONENT.
Requests the resolution of the video input port addressed by the D:P:S.
NOTE: Queries sent to port 2 will not receive a response from the encoder. All queries should be sent
to port 1.
Syntax:
SEND_COMMAND <DEV>, "'?VIDIN_RES_REF'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDIN_RES_REF'"
Returns a COMMAND string of the form: VIDIN_RES_REF-<h>x<v>,<rate>.
Requests the selected video frame burst size for streamed video output port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?VIDSTRM_BURST'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDSTRM_BURST'"
Returns a COMMAND string of the form: VIDSTRM_BURST-<burst>.
Sets the video frame burst size for streamed video port addressed by D:P:S to <rate>.
Syntax:
SEND_COMMAND <DEV>, "'VIDSTRM_BURST-<burst>'"
Variables:
burst = 150, 200, 300, 400, 500, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000 (in milliseconds)
Example:
SEND_COMMAND VIDEO_INPUT_1,"'VIDSTRM_BURST-300'"
Requests the selected video encoder codec for streamed video output port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?VIDSTRM_CODEC'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDSTRM_CODEC'"
Returns a COMMAND string of the form: VIDSTRM_CODEC-<format>.
Requests the selected frame decimation for streamed video output port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?VIDSTRM_FRAME'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDSTRM_FRAME'"
Returns a COMMAND string of the form: VIDSTRM_FRAME-<value>.
Frame decimation reduces the number of input frames to increase the quality of the video image.
Syntax:
SEND_COMMAND <DEV>,"'VIDSTRM_FRAME-<frame>'"
Variable:
frame = The amount you want to reduce the bit rate (NONE, 1/2, 1/3, or 1/4)
Example:
SEND_COMMAND VIDEO_INPUT_1,"'VIDSTRM_FRAME-1/2'"
Requests the selected group of pictures (GOP) for streamed video output port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?VIDSTRM_GOP'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDSTRM_GOP'"
Returns a COMMAND string of the form: VIDSTRM_GOP-<gop>.
