[FFmpeg-devel] [PATCH] avutil/lls: speed up performance of solve_lls

This is a trivial rewrite of the loops that results in better cache efficiency. Essentially, iterating backwards over an array is a bad idea, since it leads to many cache misses: forward iteration fetches a new cache line that gets subsequently used, while backwards iteration fetches the cache

I am attempting to convert a 0.2fps Slideshow.mov to 25fps using the fps filter. The problem is the first output frame pauses for 5 seconds. When viewing the output video I expect the frame counter to increment at a rate of 25fps but it remains on 0 for the first 5 seconds. [root@ryan tmp]# wget
