Future of ffmpeg/x264 with CUDA, OpenCL, and GPU support?

Post by LinBrake »

You'll notice I didn't mention Handbrake in the subject. ;)

I remember reading about someone from the x264(?) team attempting to port a very simple function to the GPU without much success due to the complexity of it.

Would anyone here that follows their mailing lists have any impressions on where we stand today with these?

Example: ffmpeg/x264 developer interest, code samples, pilot projects

[23:21] [mduell] anyone seen comments from the x264 team regarding opencl?
[23:21] [mduell] it's hard to get past all the posts by newbtards
[23:22] [Dark_Shikari] we have someone who's working on motion search for cuda
[23:22] [Dark_Shikari] it's rather hard to develop for an API that doesn't actually exist yet
[23:22] [Dark_Shikari] and has no implementations
[23:22] [Dark_Shikari] and nearly zero public documentation

I think that sums it up nicely. Thank you.

Ya know, one would think as developers they would have access to:

http://www.khronos.org/registry/cl/spec ... 1.0.29.pdf
http://www.khronos.org/registry/cl/api/1.0/cl.h

The specs came out in December of 2008!

Wonder what Dark_Shikari was thinking?

Ya know one would think you would have a little bit of a clue of what you are talking about before you post a snarky comment. Having the OpenCL specs is worthless with out having the API and documentation to know how apple has implemented it.

Yes. It's not particularly useful.
