Instruction Manual - NMX-ENC H.264 Encoder
Requests the format of the audio input.
Syntax:
SEND_COMMAND <DEV>, "'?AUDIN_FORMAT'"
Example:
SEND_COMMAND AUDIO_1, "'?AUDIN_FORMAT'"
Returns a COMMAND string of the form: AUDIN_FORMAT-<options>.
Specifies the audio input format for port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'AUDIN_FORMAT-<options>'"
Variable:
option = Digital, Analog, No Audio
Example:
SEND_COMMAND AUDIO_1, "'AUDIN_FORMAT-Digital'"
Sets audio format for input port (#1 based on the D:P:S) to Digital.
Queries the current selected audio input sampling rate.
Syntax:
SEND_COMMAND <DEV>, "'?AUDIN_SAMPLING_RATE'"
Example:
SEND_COMMAND AUDIO_1, "'?AUDIN_SAMPLING_RATE'"
Returns a COMMAND string of the form: AUDIN_SAMPLING_RATE-<rate>.
Requests the audio codec currently used by the input port.
Syntax:
SEND_COMMAND <DEV>, "'?AUDSTRM_CODEC'"
Example:
SEND_COMMAND AUDIO_1, "'?AUDSTRM_CODEC'"
Returns a COMMAND string of the form: AUDIN_FORMAT-<codec>.
Request the encoder if the audio stream is muted.
Syntax:
SEND_COMMAND <DEV>, "'?AUDSTRM_MUTE'"
Example:
SEND_COMMAND AUDIO_1, "'?AUDSTRM_MUTE'"
Returns a COMMAND string of the form: AUDSTRM_MUTE-<enable|disable>.
Sets the audio muting on the stream.
Syntax:
SEND_COMMAND <DEV>,"'AUDSTRM_MUTE-<setting>'"
Variables:
setting = ENABLE or DISABLE
Example:
SEND_COMMAND AUDIO_1,"'AUDSTRM_MUTE-DISABLE'"
Disables the audio muting on the stream.
Requests current audio bit rate that is being streamed out by the input port.
Syntax:
SEND_COMMAND <DEV>, "'?AUDSTRM_RATE'"
Example:
SEND_COMMAND AUDIO_1, "'?AUDSTRM_RATE'"
Returns a COMMAND string of the form: AUDIN_FORMAT-<rate>.
Specifies the audio stream bit rate for port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'AUDSTRM_RATE-<rate>'"
Variable:
rate = 64, 96, 128, 192 (all rates in kbps)
Example:
SEND_COMMAND AUDIO_1, "'AUDSTRM_RATE-192'"
Sets audio rate for output port (#1 based on the D:P:S) to 192kb per second.
