[Openquicktime-devel] Status Update

[Nick H. <nj...@ae...>]

I have re-synchronized colour model transfer code with hvirtual-1.0.0 
which gave support for a number of new transfers. Also now displays 
an error message when it is not possible to convert from one model to 
another. I have also cleaned the code up a bit and made it more OQT 
style.

I also changed the video plugin API slightly. The init and delete 
delete functions have had their parameters changed slightly so that 
they take the standard (file, track) parameters.

I have also changed the method that the color model is passed to the 
encode and decode parameters - this is now a parameter, rather than 
being passed via the oqt_t structure. I think this makes it a lot 
clearer as to what is going on - especially when colour model 
transfers are going on.


Added the following codecs:

Sorenson Video 1
TIFF
PNG
Component Video (YUV2)
Planar RGB (8BPS/Photoshop)
Apple Video


I hope to be heading towards a release soon - at which point the API 
will be frozen - well at least could be added to but not changed. If 
there are any outstanding bugs please let me know.

The two main things that I know about and need sorting out are the 
issues with Audio encoding, and the player not behaving properly. Now 
that colour model transfers are done in the library again - then the 
player should take advantage of this. It also doesn't seem to stop 
decoding or playing at the end of files...

Remaining (unsupported) codecs:

Audio:
The greater than 16bit codecs.
MS IMA ADPCM 4:1 [ms 0x0002]
DVI IMA ADPCM 4:1 [ms 0x0011]
LPC 23:1 [lpc ]
QDesign Music 1 [QDMC]
QDesign Music 2 [QDM2]
Qualcomm Purevoice [Qclp]

Video:
Apple BMP/MS RLE [WRLE] - doesn't look like BMP files to me ?!
DV [dvc ]
Motion JPEG [mjpa]
TGA [tga ]
Graphics [smc ]
H.261 [h261]
H.263 [h263]
Sorenson Video 3 [SVQ3]


A few of these would be covered if ffmpeg was used in OQT.
