H4M video file format

[Cubelover]

Some Gamecube games contain a video format named *.h4m for example Tales of Symphonia or Resident Evil. It seems that this format is not well documented. I cant find any specific information excepting this little docu: http://wiki.multimedia.cx/index.php?title=H4M

And I havent found a decoder for this format yet, every tool I tried failed. So am I correct by claiming, that the algorithm of that format has not been decrypted yet?

Thanks, well unfortunately the h4m player is just a dol executable and I need to build a GCM image. I was looking for a pc tool which can decode h4m video files to *.avi, *mpeg, and such.

I think that the best option you have is to give the dol executable a shot in Dolphin and then dump an avi from there. Or use screen capture if dolphin can't do that (I can't remember). Last option would be to actually play the movies you want on your gamecube and use a video capture device.

EDIT - found this which might help.

Thank you for the link,

No. You can not play the video in "Windows".

Thats the answer I needed.

Well, my PC is too weak for dolphin. Is it possible to make a GCM and launch it via SD-Boot?

[doktor_krotch]

Yeah, should be possible. It will depend on the compatibility of SD-Boot though.

It works fine in SD-Boot irc you need to force it to play as an PAL GCM even though the GCM is NTSC because the player dol comes from the PAL version of The Legend of Zelda: Collector's Edition.
