Thanks Luc,
that was exactly what i needed. I changed the libpwc a litle bit, now i
have a version that compiles and even works under windows (if sombody is
interested).
Sen me the patch, i'll update the package.
An other question: It decompression works perfect for 320x240. But I
tried 160x120 and there it produces only image with funny vertical
colored lines.
Hum i don't known if in 320x240, the format is compressed. Else the format is
in YUV420P in non compressed mode.
Luc
I am no linux homie, so i hope i did this right.
libpwc can now be compiled under linux and windows (MSVS).
