For example, the gauss blur filter weights can be calculated by CPU, then memcpy to device memory, and futher load to shared memory to later use. It's much speed up then calculating duplicated weights by per GPU thread. > _______________________________________________ > ffmpeg-devel mailing list > [email protected] > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > [email protected] with subject "unsubscribe". _______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel
