Hi all, I'm pleased to share a first release of vp8 codec glue for pjsip. It rely on libvpx from webm project. As usually with contributions from csipsimple it's only the C code (without toolchain integration as we use a separate one for now). Code style is probably also a little bit crappy but I count on feedback to make this better :). It should be easy to use to other platforms as I think I didn't used any stuff specific to android in this part ;) Important warning : it's very early stage and there is known limitation for unpacking frames and known possible optimizations (using vpx partitions). But it should allow to make vp8 calls between 2 pjsip clients and unless I mistaken it should comply the vp8 rtp rfc. Code is available here : https://code.google.com/p/csipsimple/source/browse/trunk/CSipSimple/jni/libvpx/pj_sources/ (there's obviously one patch to add vpx payload type https://code.google.com/p/csipsimple/source/browse/trunk/CSipSimple/jni/pjsip/patches/011add_vpx_type.h) Best regards R?gis P.S. : If you have 2 android devices with 3.x+ you can test peer to peer calls using csipsimple projects video plugin and nightly builds too (for now vp8 bitrate is fixed to 1024 kB so only suitable for good bandwidth situations but a setting will be added soon in the app) : http://nightlies.csipsimple.com/plugins/CSipSimpleVideoPlugin.apk & http://nightlies.csipsimple.com/trunk/CSipSimple-latest-trunk.apk
