[FFmpeg-devel] [PATCH] Disable SSIM in libx264 when PSNR is disabled

There is currently no way to disable SSIM calculations when using libx264 for
encoding so this patch disables SSIM calculation when PSNR calculation is
disabled which slightly improves encoding speed.

If PSNR calculation is disabled then SSIM is probably not of interest to the
user either.
