Sorry, I forgot to say I am using a RaspiCam. I have no idea how to recompile using an Armv7 toolchain, do you know where I can find a guide? I would be glad. Thanks!

You could harness the Pi' GPU by creating a plugin for mediastreamer2, but this is hard work. Also, you could use an armv7 toolchain and recompile the python wrapper with NEON enabled for VP8. I've done it, it is not too bad, but you won't get stellar performances. It seems that the USB interface for the webcam sucks too much I/O for the CPU to be a bottleneck. I'll try to review my patches for the build of the python module and maybe publish them. You have to do it under Archlinux for Pi2, on the Pi itself, though.Guillaume BIENKOWSKIhttp://www.belledonne-communications.com/ sip:[email protected] On Sat, May 2, 2015 at 1:28 AM, Nilson Magro <[email protected]> wrote: Hi there! First, sorry about my english... I managed to make video work with Linphone Python wrapper example using VP8 codec, but the CPU usage is about 80% using top command. I am not sure if this percentage is related to just one CPU core of my RPi2. Linphone log tells that most of the CPU was used by MSVp8Enc with this video configuration: bitrate=300000bits/s, fps=18.000000, vsize=320x240 for encoder. Is possible to encode VP8 or H264 in RPi2 GPU with Linphone? Any ideas how to improve this?
