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.
