Kostya's Boring Codec World

I’ve just added some support for WMV3 Complex Profile (aka old Advanced Profile).
I don’t know why most samples (users complaining about) I’ve met are anime. It’s a good chance they will work now.

And here is updated list of CP features explained:

• RES_X8 – additional bit at the end of I-frame header pointing if this is normal I-frame or this is special coded frame (I’m sure that’s exactly WMV2/8 J-frame with different header)
• RES_FASTTX – somehow interferes with P-frames but bitstream is not changed
• RES_RTM – old P-frame format (header should be the same but some additions on macroblock level). This is also quite common in old WMV3 files. Not RE’d yet

Now FFmpeg and MPlayer support VC-1 in MPEG2-TS streams which can be found on Blu-Ray discs.

Thanks to Martin for providing sample and Nico Sabbi for implementing handling of this in both FFmpeg and MPlayer.

For those whom it may interest.
What are the things needed to play HD-DVD movies in open-source multimedia player?

• Decrypted movie (use this tool)
• Demuxer support
• Video decoder
• Audio decoder

EVO demuxer is really just slightly modified MPEG stream demuxer. FFmpeg and MPlayer fresh SVN versions support it (MPlayer was there first). I don’t know about other multimedia players but that’s quite easy to implement.

Video decoding: there are three possible choices – MPEG-2, H.264 and VC-1. First two should work fine, the last one should work but with some bugs (I will fix them eventually).

Audio decoding: is also tricky – standard AC3 audio will work, DTS is supported via libdca and E-AC3 is still to be figured out.

Conclusion – try current SVN of MPlayer and see if it works to you. And if you care about Blu-Ray support (and it does not work) – please provide a sample.
