<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">It looks like this isn't doing exactly what the comment says. The intention is to update the native bridge sample rate if at least 2 people are at a higher rate. It does that part. However, the rate it chooses is the highest rate that was encountered. It may be that there is only 1 channel at that rate, though.
I think there is some tweaking needed here to ensure that the rate jumped to is one where there are at least 2 channels.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">There are problems with both of these approaches.
The current approach always picks the highest sample rate if two or more channels exist that are above the current internal sample rate. This means if a 16khz and 32khz person joins while the internal rate is 8khz, the conference will jump to 32khz even though 16khz would have been fine.
If we limit the jump to occur only when two people at the same sample rate join then the internal rate would stay at 8khz even though both a 16khz and 32khz person are present. This is not ideal either.
I fixed this with a new algorithm that first picks the highest rate two or more channels support over the internal rate, or second if multiple channels are above the internal rate but no two channels have the same sample rate, it takes the lowest one supported over the internal rate. In the case of picking the lowest sample rate above the internal sample rate, it is possible two sample rate adjustments may occur to find the optimal rate, but this would be incredibly rare.

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Wow, this API sure is easier. :-)
Is it guaranteed to process all of the data? As you could probably tell from the old code, I had to call the resampler in a loop to ensure it processed everything. I don't know, it seemed silly, but that's what I had to do to make it work.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Yes, this appears to be the case as long as the out buffer is large enough to contain all the samples which it is.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The placement of the declaration of val looks bizarre. How about just putting it at the beginning of the function?
Also, it looks like just setting val = result when val is declared would be sufficient. It's set to the same thing inside of each case in the switch.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This is correct. I made this exact same patch a couple of years ago and someone suggested the (4000000 / _rate )) / 4 trick to avoid using floating point variables. I didn't like it at the time because I knew it would change but did it anyway since it was technically ok. Now that we support a ridiculous number of sample rates this no longer holds true and floating point calculations must be used.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">reload? Does this actually support reload? If so, I think there is some additional work required here. If not, this seems like a no-op.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Umm, It does reload every time a new attribute interface is introduced, but there is no way to reload it after startup is complete. Attribute modules are set to load before channel drivers, that was the primary reason that reloads after startup are not possible. Its easy to reload the config, but it appeared to me that lots of channel drivers wanted to know about all possible formats on load for the channel_tech object's capabilities. I made the load function remove all dynamic formats on reload just in case we could use reload after start up someday. So, this is not a no-op.</pre>

Dynamic global format list build by codecs defined in codecs.conf
SILK 8khz, 12khz, 16khz, and 24khz with custom attributes defined in codecs.conf
Negotiation of SILK attributes in chan_sip.
SPEEX 32khz with translation
SLINEAR 8khz, 12khz, 24khz, 32khz, 44.1khz, 48khz, 96khz, 192khz with translation using codec_resample.c
Various changes to RTP code required to properly handle the dynamic format list and formats with attributes.
-Organizational changes
Global format list is moved from frame.c to format.c
Various format specific functions moved from frame.c to format.c
-MIS
There were several changes that I opted not to do during phase 1 that involved the proper use of formats with attributes. I felt that the phase 1 patch was too complex to attempt these changes so I have included them here. The primary change I held off doing the first time around was in the rtp_engine.c Payload and MIME type lists. These lists were statically defined which made it impossible to set formats with attributes in them. I have gone back and revised these lists to allow the flexibility required for the new architecture.

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I used the same testing I did for phase1 with phase2. This includes load testing with various codec negotiation scenarios. Speex 32 and its translators were verified using Asterisk back to back. I verified SILK using a codec translator module I'm working with. The new slinear resample code was exercised with both Speex32 and SILK 12khz/24khz translation.</pre>
