When using ppsrc=1 in fieldmatch filter and 10bit video is 420, 422, processing does not proceed.

[nicol]

Summary of the bug: When inverse telecine with combmatch=full in the fieldmatch filter, the video is not output when the chroma subsample is yuv420p10le, yuv422p10le, but when yuv444p10le, the video is output.
How to reproduce:

% ffmpeg -v 9 -loglevel 99 -f lavfi -i testsrc2=s=1920x1080:d=1:r=24000/1001,format=yuv422p10le -vf telecine,split,fieldmatch=combmatch=full:ppsrc=1 -vframes 2 tmp.mp4 -y
