OS 4.1 and Blu-Ray

Hi all !!.
I have a LG Blu-Ray writer, and i am waiting ( this month mar 2009 ) one Sam440ep + Amiga OS 4.1.
The OS 4.1 is able to Read and Write Blu-Ray disc and handle with the filesystem ?
If is possible, with that software. Thanks for all.

Lisardo.

@Fernecho

Not directly. But that'll change in due course, I'm sure, as Blu-Ray becomes more standard in computers.

@Spirantho

I know ( that what is written in the readme file ), that amiddvd support Blu-ray and you can burn software on blu-ray disc but you have the limit of 4 Gb..

@Fernecho

Ok. thanks to all for yours fast reply.
I?m happy to see this great news, now i am ready to bundle the LG Blu-Ray writer with a 500 gb hd drive and Sam440ep+OS 4.1+20" screen monitor, waiting the order of motherboard+os from ASB-Computer ( spanish delear ), download and test AmiDVD.

ciao amigos.

Is that a burner problem, or a program problem?
Is this a file size limit, or a total burn size limit?
I can burn 8.5GB dual-layer dvd's with AmiDVD, so it shouldn't be a program fault.
Can you clarify?

and stick with 4gb ? what's the point ? get a dvd burner instead.

@Swoop

You can burn even 9 gb of datas but you cannot create an iso -> 4Gb due to the actual filesystem

@nubechecorre

Why not? Both SFS/02 and JXFS support files >4GB.

@Fernecho

with the new filesystem JXFS you do not have a 4GB file limit AFAIK. I do not have the 4.1 documentation here, but I'm pretty shure I read something about it in there..

saludidos :)

@COBRA

Yes, you have right i forgot that now we have a new file system.. i have to swap from fast file system to jxfs and sfs.. oh my i have to back up everything...

@nubechecorre

You might want to stick with SFS/02 for the time being (that also supports files >4GB) because I noticed a few issues with the current version of JXFS, and a fix hasn't been released yet. SFS/02 works perfectly, I've been using it for more than a year now.

Quote:AmiDVD does not support Blu-ray burning.
The supported formats are CD-R, CD-RW, CD-RW MRW, DVD+R, DVD+RW, DVD+RW MRW (untested), DVD+R DL, DVD-R, DVD-RW and DVD-RAM, everything else (DVD-R DL, DVD+RW DL, DVD-RW DL, HD DVD, Blu Ray, ...) can't be used.

Quote:Wrong, AmiDVD supports large files. Of course that only works if you are storing the image file on a partition with a file system which supports files >4GB as well (SFS\2 or JXFS).

What issues? How can we avoid these issues in the mean time? What are the symptoms?

I've been using JXFS for a very long time now without any problems myself so I'd really like to know about these issues you found.

That's what i mean, sorry for my bad english

Sorry i don't understand the readme file then

I've been meaning to create a thread like this for a few days but haven't got around to it, come on today with the intention to do so and here it is!

Ever since I've seen that blueray RW for $400 in the shop I was thinking... hmmm...

My question was would the system read blueray roms in the first place... SAM 4.1 future proof!

Once I got that out of the way was simply going to see if there was a similair program to dvdrtools that supports blueray etc that could be compiled to write them in the meantime.

@Fernecho

Well then the problem is the burning software, the OS 4.1 not have yet a software like Nero on PC or Toast Titanium on MAC OS X. What is the feature of OS 4.1 native filesysem ? is the same that FAT32 with 4 GB limits of file size or the same that NTFS with no limits of 4 GB file size.
Is only for curiosity, i d?ont need write a Blu-Ray disc with Amiga OS 4.1 ( for the moment ) , for this job i use a PC with NERO for burn Blu-Ray iso movies.

@ssolie

Well, extracting larger lha/7zip/etc. files directly to a JXFS partition doesn't work here. It's a known issue and will be fixed.

Any plans to make support for blu ray disks for os4(reading)?

Are you talking about plainly reading DATA of a blu-ray? I.e. you want to copy something from the disc to your HD or so? Isn't that already possible? As Blu-Ray discs use UDF as filesystem... shouldn't it then already be possible to read them (as plain data discs) on AmigaOS? Or would the UDF implementation in CDFS need an update? J?rg?

But most probably you (like most others) want to *watch* blu-ray movies. And, while everyone is free to correct me, that is most likely *not* possible with our current hardware. Seeing that some systems already have trouble with simple DVD playback (speedwise), i somehow doubt that even the 1Ghz G4's would be fast enough to decode the HD video and audio data of a blu-ray... even if AltiVec is used..

After all, thats exactly why hardware decoding support is now in almost every halfway modern graphics card out there, simply because 99% of the CPUs aren't fast enough or would just let crawl the system with blu-ray playback.

Note: Thats only guessing! I didn't actually calculate it as theoretical evidence. So if somebody wants, feel free to correct me..


Anyway... i think blu-ray is fairly uninteresting as data medium only if you can't watch movies of it .. there are enough other cheaper data media out there. IF we ever get a mainboard which supports technically modern graphics cards (PCIe 16x anyone?) AND IF we get drivers for those graphiccards which can enable the hardware decoding features AND IF DvPlayer learns to playback blu-ray stuff... THEN it gets insteresting and also THEN it would make sense to support writing blu-ray data. Thats just my opinion.

@Cyborg

Yes, I've never understood the mentality that any cpu should play dvds, movies or alike. I just send them to my modded xbox or play them on my 360 off a dvdrw.

I'd simply like the option to burn blue ray at some stage, nothing else.
