Hi there,

Machine: Dedicated server debian based without GUI

I'm trying to know the difference between the libswscale spline filter used with ffmpeg and the spline36 used in avisynth or by x264.
After some research it appears that the filters are based on ffmpeg. How do I know if the ffmpeg spline is the default mode or 16, 36 or more?

FFmpeg can be compiled with the z.lib library to actualy use the spline36 with zscale, unfortunately I can't compile this shit on my debian machine :/

So, are those filters basicaly the same? What is the more judicious ways to use the best algorithm for the best results: ffmpeg piped to x264 and downscaling with spline36 or just use ffmpeg -vf scale:flags=spline ?

I can use avs script in x264 but for my purpose the ivtc ffmpeg does seems to have a better result than the "old" Telecide.Decimate method to me. So I can't pipe a inverse telecine to x264 through an avs script just to resize. Right?


thx for your help in advance.
