[Asterisk-video] video developement

[Emmanuel BUU]

Hello,

There is one particular topic (which is HUGE) but very interesting: 
asterisk codec negociations (video, audio, text, ...). It is absolutly 
awul in the official version.

We have been working on a variant of the videocaps branch that mas 
originaly brought by John Martin from Aupix and mainained by Olle. At 
some point of time, there was plans merge it into the official 1.6 
version but it never happened and I have no news of such a move. We are 
still correcting nego issues and it seems that the videocaps approach is 
reaching its limits. For two reasons:

    * The videocaps structure is redundant with nativeformats and all
      the formats used in the various chans and modules
    * The videocaps does not properly handle codec preference order.

On the other hand, I have recently discovered that the Sippy software 
company had also made a codec nego patch 
http://www.b2bua.org/wiki/AsteriskCodecNegotiationPatch that is much 
cleaner and more integreated in asterisk core.

My project would be to launch on top of the 1.6 videocaps branch a merge 
between Sippy patch, some IVèS stuff (URL sending support, RTP 
redundency negociations, ...)  and videocaps (because its handling fmtp 
attributes) and finally have a PROPER negication algorithm more in line 
with RFC 3264, including proper transcoding behavior and early media 
support. Ideally, Olle should be implicated.

Ok, that's HUGE. But why not try the collaborative effort to improve our 
beloved Asterisk software?
