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).

Caution: All channels need to have same aspect ratio, 16:9 or 4:3.

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
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.
