039ebaa5f3 lavfi: make window_func an inline function 
Eliminate lavc->lavfi dependency. The function isn't big and doesn't

a7f6bfdc18 avfilter/interlace: prevent over-sharpening with the complex low-pass filter 
The complex vertical low-pass filter slightly over-sharpens the picture. This becomes visible when several transcodings are cascaded and the error potentises, e.g. some generations of HD->SD SD->HD.
To prevent this behaviour the destination pixel must not exceed the source pixel when the average of the pixels above and below is less than the source pixel. And the other way around.

Tested and approved in a visual transcoding cascade test by video professionals.
SSIM/PSNR test with the first generation of an HD->SD file as a reference against the 6th generation(3 x SD->HD HD->SD):
Results without the patch:
SSIM Y:0.956508 (13.615881) U:0.991601 (20.757750) V:0.993004 (21.551382) All:0.974405 (15.918463)

f5a9c63401 lavfi: guess a timestamp for compat status change. 
Use the earliest input with the same status.
If that fails, print a warning and use the earliest source.
With this change, simple filter forward correctly the timestamp
of EOF.
Filters that are supposed to change it should be updated to
actually forward it.
