Some of the filters tests use globbing characters, especially
brackets for filter pad labels. While most of these strings
are way too complicated to ever match an existing file name
and are therefore kept unchanged in the command line (an old
misfeature of the shell language that happens to be convenient
here), at least one use is simple enough to match random files
lying in the current directory. If that happens, the string,
that was meant to be kept verbatim, is replaced by the file
name, and that causes the test to fail (or worse).

Comparing AVCodecContext.pix_fmt against the get_pixel_format() return
value has the side effect of calling the get_format() callback on each
slice. Users of the callback will probably handle hardware accelerator
initialization in the callback.

The FATE test is updated because the line breaks in the dialogue
rectangles are now proper CRLF.

The data does not contain timing or trailing line breaks anymore. In
addition to being less idiotic, it is consistent with other codecs and
thus allows more switches between formats and codecs. It also fixes the
issue of the trailing line returns being simple \n instead of CRLF in
the ASS rectangle dialogue (this is the reason of the FATE update).

"que" sounds like a slang word to me. This commit renames a few
variables, fix the comments and the logging messages (sometimes along
with small other typo fixes).

This fixes a integer overflow in fate

Also improve overall consistency.

Similarly to 03f5043f, we use the FTRAPV config setting.

The flags are necessary for the auto inserted scaler (because the
overlay filter needs an alpha channel for the overlay surface).

Illustrate the use of return values, av_err2str and
avcodec_get_name.

This flag is not necessary.

They were two very short files that cover ffmpeg-specific features.

Necessary after 04a530f7.

Consider the color space as an hypercone with apex alpha=0
and base alpha=1 instead of an hypercube.
Make the encoder consider very transparent colors more similar
even if the hue is very different.
This corresponds roughly to using the alpha as a weight for the
color difference.
Only 4 bits of alpha are used, because this is what dvdsub uses,
and it avoids overflows.

Fix trac ticket #2005.
