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. |
