description=>"Should frame analysis try and be efficient in skipping frames",
help=>"In previous versions of ZoneMinder the analysis daemon would attempt to keep up with the capture daemon by processing the last captured frame on each pass. This would sometimes have the undesirable side-effect of missing a chunk of the initial activity that caused the alarm because the pre-alarm frames would all have to be written to disk and the database before processing the next frame, leading to some delay between the first and second event frames. Setting this option enables a newer adaptive algorithm where the analysis daemon attempts to process as many captured frames as possible, only skipping frames when in danger of the capture daemon overwriting yet to be processed frames. This skip is variable depending on the size of the ring buffer and the amount of space left in it. Enabling this option will give you much better coverage of the beginning of alarms whilst biasing out any skipped frames towards the middle or end of the event. However you should be aware that this will have the effect of making the analysis daemon run somewhat behind the capture daemon during events and for particularly fast rates of capture it is possible for the adaptive algorithm to be overwhelmed and not have time to react to a rapid build up of pending frames and thus for a buffer overrun condition to occur.",

description=>"What method windows should use to refresh themselves, choose either javascript or http",
help=>"Many windows in Javascript need to refresh themselves to keep their information current. This option determines what method they should use to do this. Choosing 'javascript' means that each window will have a short JavaScript statement in with a timer to prompt the refresh. This is the most compatible method. Choosing 'http' means the refresh instruction is put in the HTTP header. This is a cleaner method but refreshes are interrupted or cancelled when a link in the window is clicked meaning that the window will no longer refresh and this would have to be done manually.",
help=>"From version 1.18.0 ZoneMinder can use a double buffering method to preload still image prior to displaying them on screen. This reduces flickering and makes viewing still images a more pleasant experience. However some devices may not support the JavaScript/frames combination needed to make this possible in which case this option should be switched off. As this option uses JavaScript it will only have an effect if the ZM_WEB_REFRESH_METHOD option is set to JavaScript also.",

description=>"What the bitrate of the video encoded stream shoulw be set to",

Note that this setting does not control the frame rate of the video however the quality of the video produced is affected both by this setting and the frame rate that the video is produced at. A higher frame rate at a particular bit rate result in individual frames being at a lower quality.",

help=>"When using streamed video the main control is the bitrate which determines how much data can be transmitted. However a lower bitrate at high frame rates results in a lower quality image.

An additional advantage is that encoding video at high frame rates is a processor intensive task when for the most part a very high frame rate offers little perceptible improvement over one that has a more manageable resource requirement. Note, this option is implemented as a cap beyond which binary reduction takes place. So if you have a device capturing at 15fps and set this option to 10fps then the video is not produced at 10fps, but rather at 7.5fps (15 divided by 2) as the final frame rate must be the original divided by a power of 2.",
