Blu ray bounty?

Was wondering about an bounty for blu ray filesystem. So one can read blu ray discs with blu ray players. Not super usable today but nice to have. If radeon hd drivers comes with blu ray support in the future?

Any thought? And, no, i'm not the man for the project. But would donate a couple of bucks for it.

@Antique

what all does "bluray bounty" entail? HDCP? Where all does that need to go, gfx drives, movie players, elsewhere in the OS? Disc filesystem of course. What else is required? We need to determine if this can be done by a bount person, or if more intetration in various parts of the OS is required where we outsiders cannot go.

@billt

I was thinking of only filesystem,being able to read the discs. That can maybe be done by a bounty person? Movie players etc might be a bit too advanced, or?

@Antique

I think BDs use UDF 2.x as filesystem. The OS4 CDFileSystem already supports reading of UDF 1.0.

@ZeroG

What's the difference between them? What's UDF 1 used for??

@Antique

UDF 1.x is used for VideoDVDs for example.

A BD burning program, and a filesystem to read your BD discs would be very useful IMHO, at least for backup purposes.

@Varthall

Yes. Well said.

Is it in fact possible to read BDs or do you have to decode DRM stuff as well?

Surely they've made it impossible for anyone but Microsoft and Sony to read?

@tonyw

Just reading the data is no problem at all, we just need a UDF 2.5 filesystem.

Decrypting blu-ray MOVIE data is different, and not even possible to do properly on Linux yet.

Burning on BD (not UDF2.5 though) shouldn't be any issue, FryingPan should be capable, right now, today.... unless it's anal about disc sizes.

@Varthall

I don't see why current software can't do that now? You should be able to backup and read in regular ISO9660 + Rock Ridge.

Would a bounty for the filesystem be to update the OS4 CD filesystem for this, or to make a companion or replacement filesystem?

For the commercial OS4 filesystem, I think they should update it as part of an OS4 update. Either a free point update or as a paid for OS4.2 thing. I've alrady paid for 4.0 and 4.1, and would also be paying for 4.2, so I would not pay into a bounty for something I also need to buy.

If a companion filesystem to take up the newer UDF version, or for a complete replacement for the OS4 commercial filesystem then I think a bounty could make sense.

Only upto 2GB AFAIK, ISO9660 does not support burning over that limit, so it would be useless for BD.

Varthall

@Varthall

2GB per file, not for the whole media. DVDs are both dual ISO9660 and UDF1.2 (i think it's 1.2).

@billt

A companion filesystem would make more sense, that way it can be used for HDDs and the CDMRW, CDRW, DVD+RW and DVD-RW mountlists (they are currently only use SFS, not UDF as Windows, MacOS and Linux do).

It should be available for OS4.1 (and OS4.0 if technically possible - i guess not because of large file support) and should be official part of OS4.2. However updates and bugfixes to the udf filesystem should be available immediately and not only if the OS is updated.

EDIT:
A updated SLB to boot the OS from a udf formated media would be good too.

On Wikipedia, the File size limit of iso9660, is 2gb or 4gb, but I can't find out a maximum disc size.

Also I would like to know how sucha blu-ray writer would be connected to you Amiga?
Do we have usb drivers for external optical drives, let alone Blu-ray drives?
Are any blue-ray drives ide compatible?

@Swoop

You can get blu ray player/writers with sata.

So would I need a sata controller card, or an esata card?
The LG blu-ray drive has ben updated to have USB2.0 and esata conectors, but I couldn't find a sata one.

@Swoop

A sata controller would do fine i believe.

Says this has sata connection.

@Antique

I tried to connect a sata blu ray player to my sam. Uboot seems to find the size of the disc,but os4 can't find anything. Sadly.
