Hello everyone,<br>
<br>
This is my first post. I signed up to the mailing list because I want to<br>
have a go at accelerating x264's motion estimation system using nVidia's<br>
CUDA GPU development platform.<br>
<br>
I have a couple of smaller CUDA/PTX projects behind me and would like to<br>
tackle a bigger project. I think ME would be a perfect fit. I'm<br>
fascinated by the process of "massive parallelizing", that is,<br>
transforming a problem to run on thousands of threads using an<br>
architecture such as CUDA that is based on light weight threads and<br>
program managed L1 cache.<br>
<br>
Depending on how successful the ME part is, I would then like to go on<br>
to tackle the other parts of the x264 encoder that would benefit from<br>
massive parallelization. My guess is that most or all of the parts of<br>
x264 that have x86 assembly versions are good candidates. Eventually I<br>
would like to end up with functionality equivalent to the Badaboom GPU<br>
encoder, hopefully beating it on speed and quality in the process.<br>
<br>
However, though I have been reading about H.264 ME lately, it would<br>
greatly speed up the development process if I could find someone that is<br>
very familiar with x264's ME implementation, has an interest in massive<br>
parallelization and that has the patience to answer lots of silly<br>
questions over instant messaging. Any takers?<br>
<br>
Thanks,<br>
<br>
