JVC 137 User Manual

9. JVC API for Encode
These APIs are related to camera settings. Same functions are shown on the Encode page of the WEB setting
page. Refer to the instruction manual for details on the Encode page.
Though multiple encode is available, there are limitations to set multiple encode channels. If VMS does not get
multiple streams from a camera, setting only first channel is recommended that can simplify such limitations.
Refer the Encode page of the camera to see those limitations.
Getting Compression Format
Format /api/param?encode(number).type
Example of response encode(1).type=jpeg&200 OK
Interpretation Acquire compression format of the encode channel. Encode channel is from encode(1) to
encode(3).
Allowed users admin, operator, user
Setting Compression Format
Format /api/param?encode(number).type=data
Example /api/param?encode(1).type=h264high
Example of response encode(1).type&202 Accepted(encode.status=save)
Interpretation Change compression format of the encode channel. Set "jpeg", "h264high", "h264baseline",
“mpeg4”or "off". The change of the first encode channel is availed by the API, encode(1).status=save.
Example When Changing Compression Format from H.264 to JPEG,
it is necessary that rate control setting is specified to “afs” or “vfs”.
/api/param?encode(1).type=jpeg&encode(1).cbr_mode=afs
/api/param?encode(1).status=save
Example When Changing Compression Format from JPEG to H.264,
it is necessary that rate control setting is specified to “cbr” or “vbr”.
/api/param?encode(1).type=h264high&encode(1).cbr_mode=cbr
/api/param?encode(1).status=save
Caution: In case of multiple resolution, 3 channels are available at the maximum. In case of multiple
encoding, 2 channels are available at the maximum, i.e. 3rd channel is not available.
Allowed users admin, operator
Getting Resolution (Frame Size)
Format /api/param?encode(number).framesize
Example of response encode(1).framesize=1920x1080&200 OK
