Buffer Tab

The Buffer tab allows you to specify the amount of buffering on the client when streaming the MPEG-4 file. This option is used for both MVR MPEG-4 (.mv4) and MPEG-4 Multiplex (.m4x) streaming file formats.

A minimum amount of buffering offers a just-in-time delivery of content.

A maximum amount of buffering provides the earliest possible delivery of media content. This would fill up a buffer to the extent of the maximum possible bandwidth. This will help mask network glitches which would not be possible in the just-in-time delivery, but could create extremely large
buffers in networks with large bandwidth.

Within these minimum and maximum buffer sizes, limits can be set on the amount of buffer space used. Buffer size can be limited based on a size limit value or an estimated playback time limit value. Both of these buffer size limiting values are constrained by the minimum and maximum buffer amount values.

A convenient list of buffer constraints is displayed to help select buffering. The list of buffer constraints are based on the anticipated client connection speeds.

Selecting the custom option allows you to customize the amount of buffering used on the client. The custom buffer options are:

Minimum buffer minimum buffer size, just-in-time delivery of content
Maximum buffer maximum buffer size, will help mask network glitches but could create extremely large buffers in networks with large bandwidth
Limit by time buffer size limit based on an estimated playback time. E.g. specifying 5 seconds, the buffer will be constrained to allow for buffering an estimated 5 seconds worth of content. The specified buffering is constrained to the minimum and maximum buffer size.
Limit by size buffer size limit based on a maximum size value. E.g. specifying 500,000 bytes will constrain the buffer to be a maximum of the specified number of bytes. The specified buffering is constrained to the minimum and maximum buffer size.
Limit by minimum of time and size buffer size limit based on the lesser of the specified estimated playback time and maximum size value. The specified buffering is constrained to the minimum and maximum buffer size.
Limit by maximum of time and size buffer size limit based on the greater of the specified estimated playback time and maximum size value. The specified buffering is constrained to the minimum and maximum buffer size.
