[Soc-2013-dev] Weekly Report #10 VSE

[Alexandr Kuznetsov]

==Week 10==
* Finished scopes (histogram, waveform, vectorscope)
* Created memory pathways
** Between char and float
** Passing original char to gpu and making conversion there is *much* 
faster.
** Added cl_mem to RAM conversion. However, it introduced a lot of 
crashes. I need more time to figure out what is wrong.
* Code reorganization and clean up.
* Just started implementing cache.


==Next Week Todo==
* Will commit the code over the weekend
* Cache for input strips and final images
* Add proxies
* Create duplicate scene to get correct values at different time.

== Questions ==
I think adding threading for each seqDeviceCPU. The system works well 
when it is in  playback mode, rendering multiple frames on separate CPU 
cores. However, for a single frame, this approach is limited by the 
number of non-dependent buckets. To do better, I propose to have 
multiple threads doing the same seqCommand (in a way it was implemented 
before). GPU doesn't has this problem, plus, its power should be 
sufficient for the most cases.
