bitreader-cpp

Bitstream reader implementation in C++

At the time of writing, there was no de-facto standard library for bitwise reading operations for C++. Most people either resorted to ugly unreadable hand-coded bitmask masturbation or to wheel reinvention.

After witnessing more than a couple of dozens of half-arsed, ad-hoc, bug-ridden implementations (and having taken part in writing at least what, three of those?), I thought that writing another one of them ugly crafty home-made wheels was a good fscking idea, so here we are.

Some things that remain to be done

• Examples
• API documentation
• Emulation prevention support
• [DONE] Make the brcpp::bitreader use byte source abstraction instead of raw buffers
• [DONE] Some sort of abstraction for arithmetic coding reading (can be implemented on top, but that stuff is pretty common)
  • [READ] Exponential Golomb coding with k=0
  • [READ/WRITE] Null-terminated strings
• [DONE] Reading enum values without casting around
• IEEE-754 floats (16, 32, 64, 128 bits -- no idea though what to put the 128-bit one into)
• Fixed point aka QM.N
