Interpretation Acquire resolution of the encode channel. Encode channel is from encode(1) to encode(3).
Allowed users admin, operator, user
Setting Resolution (Frame Size)
Format /api/param?encode(number).framesize=data
Example /api/param?encode(1).framesize=1920x1080
Example of response encode(1).type&202 Accepted(encode.status=save)
Interpretation Change resolution of the encode channel. Set "1920x1080", "quadvga", "1280x720", "vga",
"qvga" or "640x360". The change of the first encode channel is availed by the API, encode(1).
Maximum resolution of VN-H37/137/237/57/157/257 is 1920x1080.
Maximum resolution of VN-V17/217 is 1280x720.
Caution: All channels need to have same aspect ratio, 16:9 or 4:3.
Allowed users admin, operator
Getting Rate Control Setting
Format /api/param?encode(number).cbr_mode
Example of response encode(1).cbr_mode=afs&200 OK
Interpretation Acquire the rate control setting.
When compression format is JPEG, "vfs" or "afs" is returned. Quantization table is fixed in the case of vfs
(VariableFileSize). In the case of afs (AverageFileSize), bit rates are controlled such that the average size of
multiple files remains constant.
When compression format is H.264 or MPEG-4, "cbr" or "vbr" is returned. Bitrate is controlled to be constant in the
case of cbr (Constant Bitrate). In the case of vbr (Variable Bitrate), bitrate can be larger by input image.

Setting Rate Control
Format /api/param?encode(number).cbr_mode=data
Example /api/param?encode(1).cbr_mode=vfs
Example of response encode(1).cbr_mode&202 Accepted(encode.status=save)
Interpretation Change rate control. When compression format is JPEG, set "vfs" or "afs". This parameter is not
included file size/quality information. Parameters of JPEG File Size can be set by other APIs,
encode(number).quality.
When compression format is H.264 or MPEG-4, set "cbr" or "vbr". The change of the first channel is availed by the
API, encode(1).status=save.
