2011-09-21 15:53:56 Linphone, X264
Blair Fredericks (CANADA)
I finally got this compiled and working, few modifications here and there.
However, the x264 code is not optimized for the Blackfin Architecture.
I am running this on a BF561 dual core.
The uClinux implementation of SMP is not much help either.
Due to the fact the all threads of a process run on a single core.
One core has little to no load, the other is overloaded with Linphone and x264.
Performance is very poor.
Either I optimize the x264, which seems to be a huge task.
Still may not get me the performance I am looking for.
So my only solution here seems to be to go to Inter Core Communications.
Run uCLinux on Core A, and run bare metal or VDK on core B and use the highly optimized H.264 lib available in VisaulDSP++
Any thoughts on this would be greatly appreciated.

Intercore communication between CoreA uclinux and coreB bare metal is available on bf561, and there is also a libmcapi which sit on top of Intercore communication can be used for applications. You can referrence :
Currently the VDK implementation of intercore communication is not ready, you can just use bare metal on coreB and integrate you x264 implementation into the coreB bare metal task.
