Hi all!

I saw pure jpeg decoder was announced recently and I decided to 
publish pure D mpeg2 decoder that I wrote just for myself, with 
study aims.

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.

I already wrote it a couple of years ago with current but 
currently only transmuxing is supported  with small set of 
containers: mpeg-ts and isom (mp4) =)

I only need to publish it, but have to sort out some licensing  
problems.

Does it or do you plan to super decoding and and encoding 
programmatically (using built-in APIs)?
