[xine-user] What is the buffer type for uncompressed 8bit greyscale (avi) video.

[Klaus R. S. <ro...@mp...>]

Hi,

I have a lot (>2TB) of ``legacy'' avi files which contain uncompressed
8bit greyscale dib frames.  (Currently I rip them into PGM images
using an evil hacked up one shot prototype.  This works, but is
slow and does not allow to look at the videos in a convenient way.)

All Windows player show these avis as uncompressed 8bit indexed with a
random color table.  I especially love ``all black'' and ``hues of
green'' color tables.

There seems to be no unix player that can handle them at all.

I wanted to write a video decoder for xine, but couldn't find out
which BUF_VIDEO_* type is right.  I scanned ``src/xine-engine/buffer.h'',
but this didn't help.  As I haven't read all the hacker docs, and
not all the source code I do not know how / where these buffer types
are generated (I guess hard coded).  Most likely buffer types are
hard coded and there is no BUF_VIDEO_* for this kind of buffer,
yet.

Any help in getting this buffer type (into my code and into buffer.h)
is highly appreciated.  Any AAAP (as acurate as possible) pointer
to fine manuals is welcome.  I enjoy verbose answers without
references, too.
