Can the RPi utilise a USB Blu-ray player?

Tue Oct 16, 2012 5:29 pm

Title says it all really - naturally you'd need to use something like Raspbmc to access the drive and process/display the data, but will the RPi successfully access a USB Blu-ray drive?

Also, how are discs handled from various regions? Any issues playing back Region A, B, C as required?

Any iddues with protection on the discs? (easily worked around using a Blu-ray drive under windows by purchashing AnyDVD HD for example).

Thanks

What kind of protection is there anyway ?
I heard that Avatar Discs used some kind of Java thingy for copy protection.
DVD Drives and DeCSS work on the Pi (and under XBMC).

Hmm...good question. Accessing the drive should pose no problem, but playback of a bluray may be an issue.

Will test this out.

I played 2 regular DVDs for a bit on my Slim External LG BP40NS20 USB BD Writer drive. Worked fine for me.

Can't say anything about regions because I only have Region 1 discs.

Make MKV works fine on BD's and the Pi plays those fine. I just watched The Avengers BluRay Rip and Prometheus this evening for about the 4th time, lol

Can you play the Blu-Ray directly ?

Thanks for trying that notarat - how about playing a disc directly from the Blu-ray drive?

you best bet is to use it on windows and use make makemkv to backup the movie. the dts-mta audio tracks could be overkill for the pi, you better convert that to ac3 or to normal dts if you have a AV amplifier

But backing up the discs is time consuming - much better to be able to pop the disc into a drive. :)

I believe that no linux player can handle blu-ray discs at the moment because of the encryption, and its not likely that linux will ever be able to play blu-ray discs, unless someone can convince sony to give up their patent on blu-rays.
Until then the only way to play them is to use a program like anyDVD to remove its protection, if you then make a blu-ray disc with the region free data it may play, but xbmc still cant handle the menus, and as far as I know no other linux player can show blu-ray menus either.

@tomolac
I think DeCSS is a good counter-example to your hypothesis.
But I can't disprove you on the case of Blu-Rays :D
OT : Is it true that HDCP/HDMI allows devices to be remotely (by disks or updates)
rendered unusable if they have a copy protection flaw which can't be fixed ?

I've just tested whether the RPi is capable of playing BluRays. While omxplayer is perfectly capable of playing a BluRay quality m2ts stream, the data rate produced by the libbluray example program "libbluray_test" is only about 2.6MB/s when running standalone, utilizing about 100% of the CPU on a non-overclocked RPi. Yet a BluRay-Disc stream has a data rate of 32 MBit = 4 MB/s.

Trying to playback the stream over a pipe using omxplayer only results in stuttering video.

I think this bottleneck may be caused by the decryption process, so a optimized version of libgcrypt may help here.

Thanks very much for looking into that - maybe one day eh? :)
