...represented, and perhaps something to accurately specify
the colour space, basically what you are doing is opening up millions of
possibilities, most of which are completely useless. If you have a bits per
channel field in RGB, what about RGB24, 3 channels, 8 bits each, but padded
into 32 bits. RGB555, 15 bits, padded to 16.
There's thousands of invalid possibilities, and only 15-20 or less valid
ones... only really 3-5 commonly used.
If someone wants to go crazy and design a franken-yuv format for some
bizarre reason, then they can easily make another stream format... but you
can prett...

Oh, thank god you corrected this. :-) I was contemplating an "OggVid" format,

That's one of the fields we're currently lacking on the wiki, and one which I
don't understand either.

Or RGB 565, giving green an extra bit because the human eye can see twice as
many shades of green than red or blue.. but yes, RGB doubles the issue, which is
why we need a seperate codec for it.

DirectShow Theora Issue with RGB24
Hi,
I hope you can help, I am in need of some assistance with the DirectShow
filters for Theora.
I have successfully created a working capture graph using OGG / Vorbis /
Theora, however, when I add a Sample Grabber Directshow filter between the
FFDShow decoder and Theora Encoder, this results in the video file being
mirrored vertically. I have noticed that the original CaptureGraph was

add swfdec_bits_get_bu16
Make the z_stream part of the SwfdecDecoder struct
rate == 0 is allowed now
fix wrong type in macros
remove \n from debugging messages
fix RGB555 images
append the right SwfdecContent to the list
get the next_event time before comparing
Fix includes
add jpeg_rgb_decoder_get_image_size
rework cache handling
The key should be static const, we don't want it on the stack
Merge branch 'master'...
