https://origsvn.digium.com/svn/asterisk/branches/1.8 ........ r317478 | russell | 2011-05-05 17:53:45 -0500 (Thu, 05 May 2011) | 12 lines Fix some consistency issues with jitterbuffer config. Store the defaults noted in the sample config files in the jitterbuffer config data structure. This makes the CLI commands that output these settings show the right thing. Also only show the settings that are relevant in the settings CLI commands, based on which jitterbuffer is selected and whether it's enabled.

* The following parameters are used in the driver:
|
|
*
|
|
* FRAME_SIZE the size of an audio frame, in samples.
|
|
* 160 is used almost universally, so you should not change it.
|
|
*
|
|
* FRAGS the argument for the SETFRAGMENT ioctl.
|
|
* Overridden by the 'frags' parameter in oss.conf
|
|
*
|
|
* Bits 0-7 are the base-2 log of the device's block size,
|
|
* bits 16-31 are the number of blocks in the driver's queue.
|
|
* There are a lot of differences in the way this parameter
|
|
* is supported by different drivers, so you may need to
|
|
* experiment a bit with the value.
|
|
* A good default for linux is 30 blocks of 64 bytes, which
|
|
* results in 6 frames of 320 bytes (160 samples).
|
|
* FreeBSD works decently with blocks of 256 or 512 bytes,
|
|
* leaving the number unspecified.
|
|
* Note that this only refers to the device buffer size,
|
|
* this module will then try to keep the lenght of audio
|
|
* buffered within small constraints.
|
|
*
|
|
* QUEUE_SIZE The max number of blocks actually allowed in the device
|
|
* driver's buffer, irrespective of the available number.
|
|
* Overridden by the 'queuesize' parameter in oss.conf
|
|
*
|
|
* Should be >=2, and at most as large as the hw queue above
|
|
* (otherwise it will never be full).
