This is a particularly full-featured video codec. The "videocodec" keyword
identifies the fact that this is the start of a new video
codec. "indeo5ds" is MPlayer's unique name for the codec.

this name with the -vd/-ad option.
The next line has the keyword "info" which specifies a human-readable
comment accompanies this codec.

The "status" keyword carries information about the codec's functional
status. MPlayer currently recognizes 4 status levels: working, buggy,
crashing, and untested.
crashing, and untested. When it gets to codec auto-selection, it tries
untested first (to force the users to test it for us and report result :)),
then working and finally buggy ones. Codecs marked crashing won't be tried,
unless explicitly (-vd/-ad) selected.
The next line lists 4-character codes (FOURCCs) that are associated with
this codec. There can be more than one FOURCC specified on a fourcc line
as long as they're separated with a comma. There can also be multiple
fourcc lines in the codec.
fourcc lines in the codec. There also can be a second fourcc given, separated
with a space. MPlayer will replace the original fourcc in the headers with
this one before opening the codec. It's useful for win32 codecs checking for
the fourccs.
The "driver" keyword associates this codec with an internal MPlayer
decoder module. MPlayer has a module named "dshow" that handles data
encoded by the codec.

The "dll" keyword specifies which Win32/XAnim/Real binary module needs to be
loaded in order to handle the specific media type. This keyword is usually
only used in conjunction with the dshow, vfw, acm, and xanim drivers since
only used in conjunction with the dshow, vfw, acm, xanim and real drivers since
they all manage communication with binary-only modules.
The "guid" keyword identifies a 16-byte Microsoft GUID that some media
files use to identify codecs.
files use to identify codecs. Used only for win32 dshow codecs.
The "out" keyword identifies which output format that the decoder is known
to output. Just like the fourcc line, there can be multiple out lines or
multiple comma-separated output formats on the same line. The output
formats should be listed in order of preference.
The outfmt values can be followed by one or more flags, like flip, noflip,
static, querty. TODO: describe tehse in detail.
