Of course NOT yet (except this)

He is expert of mpeg en/decoding. he simply analized DivX avi files
and find the meaning of the bits. It seems to weird, but not impossible.
At least I did the same with lossless archivers at the time of writting ESP
(I was able to unpack ZIP and RAR files without having rar sources)
If you spent half year debugging compressor/decompressor by watching binary
dump (or hexdump) then you'll understand output of similar compressors too,
and you'll be able to modify your decoder to understand it.
