Hi all
As we effectively have now 3 implementations of RAW LSB support, some feedback
would be welcome!
latest is:
0307 1:36 To FFmpeg devel ( 14K) [FFmpeg-devel] [PATCH 1/2] libavcodec/ffv1: Support storing decorrelated LSB raw without rangecoder
The first was a hack basically, the 2nd went through the range coder
and the 3rd is linked above
Also teh 2nd and 3rd allow the quantization to be adjusted, with shift
and offset, this machienery could be useful for improving compression
Especially for higher bit depth
(thats in theory, practice can always behave odd)
thx

Many things microsoft did are stupid, but not doing something just because
microsoft did it is even more stupid. If everything ms did were stupid they
would be bankrupt already.
