I saw pure jpeg decoder was announced recently and I decided to
publish pure D mpeg2 decoder that I wrote just for myself, with
I didn't test it exhaustively, so don't judge me for bugs)
Currently it supports only progressive sequences with no B frames.
As for performance, it's 5 times slower than ffmpeg
implementation, optimizations are required.
Does someone want to write pure D AVC or HEVC decoder/encoder? =)
P.S. It sometimes has some artifacts, I didn't try to fix them.
