Patch updated against latest SVN.

Also I just run a test, and I noticed many garbled output files.

To test add a line in Makefile:

LAVFI_TESTS =           \
    crop                \
...
    lavfi_pix_fmts      \

and run make regtest-lavfi_pix_fmts.

In order to see all the issued files I'm running this script:
for f in (ls tests/data/lavfi/*.nut); do ~/src/ffmpeg.git/ffplay $f; end

and then I'm visually checking the output files.

I noticed garbled output with the formats:
gray16be
nv12
nv21
yuv420p16be
rgb444 / bgr444

and there are possibly others, so help in this area is much
appreciated.

Regards.
