Getting information about a Blu-ray video's format

[ghell]

The following all assumes that the particular disk in question isn't encrypted:

I've read that Blu-ray can use several formats for the actual video on the disk. For example MPEG-2, MPEG-4 and VC-1 (I've also read that a small number of movies are released as 1080i rather than 1080p, and so on).

Is there any way to tell which format has been used on a particular video stream? Also, is there any software out there that can convert movies from a Blu-ray disk to raw YUV (or pull the MPEG-2/4, VC-1, etc stream off onto the hard disk and then convert to YUV from there), for use with something like VC-2 (Dirac) encoding or would this just be pointless if too much information had been lost putting the video stream onto the disk (encoding with MPEG-2/4, VC-1, etc) to even bother trying to re-encode with VC-2?

Thanks

I'm not sure about any software, at the moment. However, if you own a PS3 and press the display button, it'll show you the video encode, bit rate, etc. Perhaps other players will, too. I don't own any, though.

Download Tsmuxer, place the main video stream in there and it will tell you all the specs. Resolution, audio stream, encode...etc.

Thanks for the info but I don't own a PS3, which is why I posted in the PC section (I also want to do some things with it on the PC once I know it )

Edit: (new post I didn't see when I replied)
I'll take a look at tsmuxer. Does this modify it at all (re-encode or whatever) or does it produce the original data just by doing something like merging containers into 1 ts file? Can it output YUV for use with something like schro_encode?

I don't think this is the forum, or even site to talk about processing BD rips. Try Doom9 or Afterdawn for this topic.

PS: tsMuxeR is just a muxer/demuxer, no recoding involved.
