Hi,
why not look at SPICE html client instead? It's already JS code so
it shouldn't be that different.
For QUIC you can see Uri's link if you need some notes, LZ is more or
less standard on decoding, you have uncompressed sections and
references to previous chunks, so it's just a matter of understanding
these encodings.
There is also a link in spice-common/common/lz.h:
" dictionary compression for images based on fastlz (http://www.fastlz.org/) "
Uri.
