storage requirement. In the request of same video quality, H.264 contributes to less bandwidth and storage
requirement, which is much more efficient than MJPEG. Therefore it is usually a better selection to select
H.264 format if there is no particular reason for MJPEG.
GOP -
In MPEG4/H.264 video coding, GOP (group of pictures) describes how the different types of frames are
arranged. The frame types implemented here are I -frame (full image information) and P -frame
(motion-compensated difference information). This setting configures the GOP length which is the number of
frames before next I-frame appears. Having more I-frames usually increases the stream size, and therefore
more bandwidth and storage are required.
Frame Rates -
The Frame Rates defines the number of frames that will be displayed per second. The frame rate setting can
affect the target bit rate (bandwidth requirement) and storage requirement.
Note:
While multiple streaming is possible, each stream has its limitation and dependency to other stream. See
“ Video Stream Specification ”.
