This currently works for most users because
avformat_open_input sets it, but this patch fixes any
applications not using that function.

No real difference in quality, its a bit slower for the same dia_size as more
vectors are searched for the same dia_size

Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

This very very slightly improves quality, no measurable speed change

The printed stuff should be useless to the average user and its certainly
not an error.

APIC tags always have a description. Tag writers obviously leave it
empty if there is no description. In this case, libavformat would export
"" as title. Do not set the title instead.

AV_PIX_FMT_GRAY8/16 are considered YUV formats, and the color_range is
not set - so the API user will have to assume limitted range. (Unless
the API user adds a special-case for the PNG decoder.)

Just export the correct range - full range.
