<P>The <B>GIF</B> format is a common format for web graphics. There are two
versions of the GIF spec, GIF87a and GIF89a. The main difference is that
GIF89a allows for animation. MPlayer supports both formats through use
of libungif or another libgif-compatible library. Non-animated GIFs will
be displayed as single frame videos. (Use the <CODE>-loop</CODE> and

<P>MPlayer currently does not support seeking in GIF files. GIF files do
not necessarily have a fixed frame size, nor a fixed framerate. Rather,
each frame is of independant size and is supposed to be positioned in a
certain place on a field of fixed-size. The framerate is controlled by
an optional block before each frame that specifies a next frame's delay

<P>Standard GIF files contain 24-bit RGB frames with at most an 8-bit
indexed pallete. These frames are usually LZW-compressed, although
indexed pallete. These frames are usually LZW-compressed, although
some GIF encoders produce uncompressed frames to avoid patent issues
with LZW compression.</P>
