I what Timo is suggesting is that this path uses TexImage2D (hopefully TexSubImage2D) to upload the frames of video as they are decoded. | that it's reading the data out of the framebuffer. The reading data out | should be the slow part. sysprof would confirm for you. Which would be total insanity. Any application that is going to use copy-to-texture should use CopyTexSubImage2D. Notice that I said CopyTex*Sub*Image2D, not CopyTexImage2D. Any other usage is not the performance path on any driver. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) iD8DBQFIUrrqX1gOwKyEAw8RAvFQAKCgd0rOERCtkuC6RRKxfQSGl5uXxQCdEjPn KY7TO8XwAyWq1mBTldeZJl8= =nKDY -----END PGP SIGNATURE----- ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
