[GEM-dev] video1394 under linux : preliminary

[IOhannes zmoelnig]

hi gem'ers

i have just committed some changes to the CVS, mainly these are:
added new colour-conversions in GemPixUtil.cpp (these should reside in 
GemPixConvert.cpp (with subclasses GemPixConvert_mmx.cpp and 
GemPixConvert_altivec.cpp)) rather...)

have finally made a working (on my system ;-)) videoDV4L.
to make it work, you will have to have libdv2 and libdv2-dev packages 
installed (on debian systems. on other systems i don't know yet)
and you need the dv1394-module loaded (only on new! (should be 2.4.21 i 
think) kernels). this should create /dev/ieee1394/dv/host0/PAL/in and 
similar devices with devfs. (you will need these !!)

finally, make a [pix_video] object, and send it a "[driver 1(" message 
(which will switch from video4linux (0) to df1394)

features:
capture dv in greyscale, yuv and rgba

bugs:
very unstable (crashes when stopping the rendering chain and reopening it)
no resizing (so only native NTSC/PAL resolution)
other bugs
