My long-term backups are written to M-Disc platters (100GB BD-R) through a USB-attached BD-RW drive. This works well, but I would like to be able to check if there is a blank disc inserted in the drive at the start of my backup scripts. How do I do that? - command line? - ioctl system call? And how do I decode whatever status bytes it reads out?

I've been attempting (somewhat fruitlessly) to rip a Blu-ray disc that appears to have a bad sector on it (thanks, BBC). The problem is, after using MakeMKV to try and backup the disc, the drive is unable to read the disc at all, and after this point, the drive cannot read *any* Blu-rays at all. The drive makes a whole bunch of seeking noises, and spins up a bunch of times, but never gets anywhere, and eventually stops trying. It doesn't show anything in lsblk, no disc appears to be able to mount, nothing. CDs and DVDs continue to work fine, however. The really weird part is that this is the second time it's happened in about a week. The first time, I put it down to a hardware failure, assuming the blue laser had died, and bought another. After patching the firmware so it works well with MakeMKV (LibreDrive and all), I ripped a Blu-ray as a test; it worked fine, so I got to work on this disc. I did the same as I already said, and the exact same thing happened. I refuse to believe that this is a hardware issue, since it seems impossibly unlikely that two drives (albeit with the same model number and firmware) would have the exact same problem after failing to read the exact same disc. I've never heard of a drive failing because it couldn't read a disc properly. I've tried restarting and updating my computer, to no avail. The drive refuses to take any and all Blu-ray discs, including ones that I know for a fact *work*. The drives are the same model, the LG BH16NS55, and both have had their firmware flashed to WH16NS60 1.02MK. I'm running on Arch Linux. Thanks!

I'm using Fedora v32. The only support I could find for Blu-ray burners on Linux is either xfburn or growisofs. I'd like to add files for backup and then burn it. When I tried using xfburn and selecting "Pioneer BDR-XD07B" under "Burning device", after adding the files to be saved, I get: > Failed to unmount 'Blank DS-R Disc'. Drive cannot be used for burning. Couldn't find an example of growisofs adding files to be burned then burning the disc. I assume I'll need to use mkisofs to make an ISO file with the data files in it then burning the Blu-ray disc with that ISO? I looked for Linux drivers for the Pioneer BDR-XD07B but found only Windows and MacOS drivers. Suggestions?

I have some Bluray disks I am attempting to rip video from. Normally I'd use ffmpeg and select a playlist to rip and be done with it. With these discs, however, the videos make use of the alternate camera angles feature. My understanding is that both camera angles are encoded into a single video stream. The video codec on disc is VC-1. I have tried just ripping the playlist as usual. On my current machine, and playback with mpv simply will show one camera angle at a snail's pace (no hw-accelerated VC-1 decode). Re-encoding to another format such as FFV1 will play at full speed, but again, the one camera angle. My goal is to rip these videos with the camera angle of my choice using open source software. I've tried opening up an .mpls file with a hex editor to peek at which .m2ts files are referenced so I can rip those individually and stitch them together, but I have not found success in ripping the individual .m2ts files. If I set one as an input to ffmpeg: ffmpeg -i BDMV/STREAM/00000.m2ts -map 0:v -map 0:a -c:a copy -c:v copy output.mkv, I get back "*BDMV/STREAM/00000.m2ts: Invalid data found when processing input*". I assume that's because it needs to be decrypted? Not sure how to get ffmpeg to make use of libaacs to decrypt when trying to use .m2ts as input rather than .mpls So, how can I rip specific camera angles from a bluray video using free open source software available on Linux?

I'm having trouble mounting my optical drive in Linux Mint 19.3. I figured this constituted a new question because of how outdated other posts have been on the topic. My system:

I have also already installed libdvd-pkg, vlc player, ubuntu-restricted-extras, libdvdcss2, libdvdnav4, and libdvdread4. There are no prompts upon insertion of any type of media disk (bluray, dvd, or cd) I feel I'm running in circles and am unsure where to go next.

I have some retail Blu-Ray movies with DRM that I want to watch on my Linux desktop. I want to watch the movie directly from the disc. Tutorials I found online tell me how to rip it to a file, but I don't want to use up that much hard drive space when I will only watch the movie a few times. How can I do this?

I want to use 100GB M-Disc for Backup. How can one determine whether the M-Disc Writing was engraved properly and successfully on the non-volatile substance? I plan to use Brasero for writing. What does one have to do, burn with brasero and everything is figured out automatically when you insert an M-Disc? I have just got a Pioneer BDR-XS07S Blu-Ray Burner. I am using Ubuntu 20.04 LTS.

I tried to download the Debian "testing" (aka "stretch) [install media that is blu-ray](http://cdimage.debian.org/cdimage/stretch_di_alpha5/amd64/jigdo-bd/) because I wanted a one disk solution. When I went to the Debian site to download the blu-ray disk... there was 3 disks... arg. The regular Debian dvd install media also has 3 disks. **Given that the dvd and blu-ray install media both have 3 disks... what is the purpose of the blu-ray version?** - [debian "testing" (aka "stretch") install media](https://www.debian.org/devel/debian-installer/) - [blu-ray media](http://cdimage.debian.org/cdimage/stretch_di_alpha5/amd64/jigdo-bd/) - [dvd media](http://cdimage.debian.org/cdimage/stretch_di_alpha5/amd64/iso-dvd/)

I have a couple of large files I want to burn to an M-Disc 50G BD-R DL. Files are larger than 4G so I have to use UDFv3, if I am not mistaken. (Or split, which I am not especially keen on doing.) A graphical tool is not an option (no X on the server and those do a remarkably bad job on that anyway in my experience) so what I plan on doing is the following: 1. find the capacity of my medium with dvd+rw-mediainfo. 2. create a temporary file with dd if=/dev/zero of=/tmp/bd.udf bs=2048 count=n with n being an integer extracted from mediainfo's output. 3. create a UDF filesystem on that temp with mkudffs -b 2048 -l somelabel /tmp/bd.udf 4. mount it with mount -o loop -t udf /tmp/bd.udf ./mntpt 5. populate it with my files cp xyz* mntpt/ 6. unmount it umount ./mntpt 7. burn it with growisofs -Z /dev/dvd=/tmp/bd.udf -speed=5 Please correct me if this is not a good procedure. I'd be grateful for improvements. What really confuses me is the output of dvd+rw-mediainfo: INQUIRY: [PIONEER ][BD-RW BDR-UD03][1.11] GET [CURRENT] CONFIGURATION: Mounted Media: 41h, BD-R SRM Media ID: VERBAT/IMf Current Write Speed: 6.0x4495=26970KB/s Write Speed #0: 6.0x4495=26970KB/s Write Speed #1: 4.0x4495=17980KB/s Write Speed #2: 2.0x4495=8990KB/s Speed Descriptor#0: 00/24438783 R@6.0x4495=26970KB/s W@6.0x4495=26970KB/s Speed Descriptor#1: 00/24438783 R@4.0x4495=17980KB/s W@4.0x4495=17980KB/s Speed Descriptor#2: 00/24438783 R@2.0x4495=8990KB/s W@2.0x4495=8990KB/s :-[ READ BD SPARE INFORMATION failed with SK=5h/MEDIUM NOT FORMATTED]: Wrong medium type READ DISC INFORMATION: Disc status: blank Number of Sessions: 1 State of Last Session: empty "Next" Track: 1 Number of Tracks: 1 READ FORMAT CAPACITIES: unformatted: 24438784*2048=50050629632 00h(6000): 23652352*2048=48440016896 32h(0): 23652352*2048=48440016896 32h(0): 11200512*2048=22938648576 32h(0): 24307712*2048=49782194176 READ TRACK INFORMATION[#1]: Track State: invisible incremental Track Start Address: 0*2KB Next Writable Address: 0*2KB Free Blocks: 24438784*2KB Track Size: 24438784*2KB READ CAPACITY: 0*2048=0 Should I use the "unformatted" block count for the temp file?

The disc was readable though and md5 sums were fine. Can someone point me to a definitve guide for writing BDs on the command line?

I've just installed a Pioneer BDC-207DBK blu-ray drive into my Debian Jessie media/file server. The idea being I want to rip my DVD/Blu-ray collection to the hard drives and access them from within my network. The drive itself is reading DVDs without issue, but won't read Blu ray drives. I get the following information for the drive when I run hwinfo 69: SCSI 100.0: 10602 CD-ROM (DVD) [Created at block.249] Unique ID: KD9E.ZlUAb_nX_38 Parent ID: w7Y8.q8BnP6yP4VA SysFS ID: /class/block/sr0 SysFS BusID: 1:0:0:0 SysFS Device Link: /devices/pci0000:00/0000:00:1f.2/ata2/host1/target1:0:0/1:0:0:0 Hardware Class: cdrom Model: "PIONEER BD-ROM BDC-207D" Vendor: "PIONEER" Device: "BD-ROM BDC-207D" Revision: "1.00" Driver: "ata_piix", "sr" Driver Modules: "ata_piix" Device File: /dev/sr0 (/dev/sg1) Device Files: /dev/sr0, /dev/cdrom, /dev/cdrw, /dev/disk/by-id/ata-PIONEER_BD-ROM_BDC-207D, /dev/dvd, /dev/dvdrw Device Number: block 11:0 (char 21:1) Features: CD-R, CD-RW, DVD, DVD-R, DVD-RW, DVD-R DL, DVD+R, DVD+RW, DVD+R DL, BD Drive status: no medium Config Status: cfg=new, avail=yes, need=no, active=unknown Attached to: #34 (IDE interface) Drive Speed: 125 I've already ran the following to install items: apt-get install build-essential libc6-dev libssl-dev libgl1-mesa-dev libqt4-dev curl vlc I have handbrake already installed for ripping, and have installed MakeMKV. When I load a disk into the drive for MakeMKV to detect, it does the "reading" but returns the Type as "No disc". I've spent the last few hours looking round google to see if I could get it working, but haven't been able to. How can I get Debian to read the blu-ray discs?

I need to provide the means to patch red hat systems at remote locations that do not have internet connections. My original plan was to reposync the RHEL-workstation repository and throw that along with other required patches on an external ssd and ship it to the sites, however, due to where I work this is not possible. My next thought was to use blu-rays, as usage of disc media is acceptable. I grabbed the rhel workstation repository with reposync yesterday and it was a little over 40 gigs, so dual layer blu-rays should do the trick. Here's my first round of questions: Is there any way I can reduce the size of the repo? Specifying --newest-only with reposync decreases the number of packages from 20,000+ to under 5,000. Does this only get the newest version of each package where as without --newest-only it gets several iterations of each package? Will I have any issues with RHEL 6 and blu-ray data discs? What software do you recommend for burning blu-rays fom RHEL? My next issue is that it may take weeks/months to acquire blu-ray drives for this task... in the short term I'm looking to DVDs. I'm working on getting some dual layer DVDs, but who knows if that will happen... worst case scenario is I have to fit the 40+ gb repo onto DVDs. What is the best way to go about this..? Use tar to create a compressed archive I could split up into 4GB chunks? What should I do to compress the 40 gb to the smallest amount? As I write this out and think about it... I should probably put a hold on things until we are able to get blu-ray burners. Burning 10 DVDs per site, then copying over the data from each disc to EACH system and rebuilding the repo sounds insane. Is there an overall better solution to what I'm trying to do?

How do I mount a Blu-Ray Movie Disk in FreeBSD 10? I don't need to decrypt the disk, I just need to access the data and copy it to an ISO files so I can transfer the image to another a windows computer to decrypt there with MakeMKV.

Pardon me if this is something that "everybody knows," but gedit (the gnome gui text editor) has a dependency on libbluray. I've googled and read the release notes for gedit, with no luck, and I can't for the life of me think of a legitimate reason for this. I'm using RHEL7 Workstation, but I suspect any gnome DE will have this same strangeness.

On Ubuntu Linux, I wrote files to a BD-R using growisofs, per: growisofs -Z /dev/sr0 -R -J -f -graft-points ... Then I wanted to add more files, but I was not paying enough attention, I ran growisofs with the -Z option again instead of switching to -M. Now when I mount the disc, I only see the files from the second burn. Is there something I can write again to the disc to make both sets of files visible (as if I had correctly used -M the second time)? I still have all the original source files, so I could simply burn a new disc and do it correctly - i.e. I don't need to get the data to prevent loss. I just hoped there may be a way to not waste the disc since all the data is burnt on there.

I wanted to know if there's any software in GNU/Linux which can read BluRay subtitles (HDMV PGS). I'm not talking about making an OCR to convert them to SRT like everyone asks, but just reading them to see the timing of each line, and open the image representing the writings in each line. I want to read their content without having to play the whole film, I don't care about being able to edit the lines or converting the subtitle in any other format. According to mkvextract the extension should be .sup, but when extracting some HDMV PGS subtitles with that extension, neither GNOME Subtitles Edit nor Gaupol seem able to read it. Does anyone know of any software which is able to read them?

I want to learn which media my optical device can read and write to?

I backed up my MacBook using a Blu-ray burner on my CentOS server. When I try to mount the Blu-ray disk, $ mount -t hfsplus /dev/sr0 /mnt/bluray I get the error, mount: no medium found on /dev/sr0 I _believe_ the write was successful. I use a disk cataloger immediately after I burn every disk, and I have a catalog of the disk contents built from the mounted disk. I didn't give a thought to testing the disk since it was created from files copied to the server and the disk was clearly mounted during the cataloging step. **How I made the backup** Because I can't find a Linux package which plays nice with my Blu-ray drive, I use K3B to write an ISO from files copied to the CentOS server. Then I use growisofs to burn the Blu-Ray: $ growisofs -Z /dev/sr0=mrwizard-archive-001.iso |& tee -a burn.log Other Linux disks I've made will mount, so I know it's not the drive or drivers. I'm 99% sure these are the steps I followed for this Mac OS backup. A grep in history shows I copied files to a directory with the same name as the Blu-ray disk image (also found in history). [UPDATE, just in case it wasn't clear, the backup was made four months ago in March] There are numerous posts around the net talking about hfs+ and CentOS. These recommend the kmod-hfsplus package which I have installed. This package was necessary to transfer the files to CentOS. Also, here's the tail from the growisofs log, 24024383488/24142608384 (99.5%) @1.8x, remaining 0:14 RBU 100.0% UBU 54.3% 24049221632/24142608384 (99.6%) @1.7x, remaining 0:11 RBU 99.8% UBU 43.5% 24078647296/24142608384 (99.7%) @2.0x, remaining 0:07 RBU 100.0% UBU 40.3% 24102764544/24142608384 (99.8%) @1.6x, remaining 0:04 RBU 100.0% UBU 45.7% 24126881792/24142608384 (99.9%) @1.6x, remaining 0:01 RBU 93.8% UBU 39.2% /dev/sr0: flushing cache /dev/sr0: closing track /dev/sr0: closing session :-[ CLOSE SESSION failed with SK=5h/INVALID FIELD IN CDB]: Input/output error. This last error seems to be related to something else . As the OP in this post says the disk is mountable and readable even with this error. Why growisofs made Blu-ray disk won't mount with Mac OS files? Why would the disk appear to be mounted, only to fail mounting later? What might happen as a result of these steps (k3b made iso, growisofs) and files from Mac OS, which might cause problems with this media? What don't I understand about hfs+ file system, k3b iso's and growisofs which makes my disk a coaster? $ dvd+rw-mediainfo /dev/sr0 long INQUIRY: [ATAPI ][iHBS112 2 ][CL0J] MODE SENSE[#3Fh]: 01: 00 80 00 00 00 00 00 00 00 00 05: 40 05 08 00 00 00 00 00 00 00 00 00 00 96 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 08: 04 00 00 00 00 00 00 00 00 00 0D: 00 00 00 3c 00 4b 0E: 04 00 00 00 00 4b 01 ff 02 ff 00 00 00 00 18: 00 01 00 01 00 00 00 00 00 01 00 01 00 00 00 00 00 00 00 00 00 01 00 01 00 00 1A: 00 03 00 00 02 58 00 00 04 b0 1D: 00 00 00 00 00 06 04 b0 00 00 2A: 3f 37 f1 77 29 23 21 14 01 00 20 00 21 14 00 10 21 14 21 14 00 01 00 00 00 00 21 14 00 09 00 00 21 14 00 00 1b 91 00 00 16 0d 00 00 10 8a 00 00 0b 07 00 00 05 84 00 00 00 00 00 00 00 00 00 00 00 00 30: 2e 00 00 00 00 00 00 00 00 00 00 00 00 00 GET [CURRENT] CONFIGURATION: 0000: 00 43 00 00 00 42 00 00 00 41 00 00 00 40 00 00 00 2b 00 00 00 1b 00 00 00 1a 00 00 00 16 00 00 00 15 00 00 00 14 00 00 00 13 00 00 00 12 00 00 00 11 00 00 00 10 00 00 00 0a 00 00 00 09 00 00 00 08 00 00 00 02 00 00 0001: 00 00 00 07 01 00 00 00 0002: 02 00 00 00 0003: 39 00 00 00 0100: 0105: 00 00 00 00 0108: 33 37 37 32 35 31 32 30 31 32 20 32 31 36 31 30 37 35 30 30 34 34 34 20 //ERROR OUTPUT :-( no media mounted, exiting...

I'm having a really weird problem after installing a new Blu-Ray/DVD drive last night into a SATA 3 port on my desktop. My installed Linux distribution (Ubuntu 12.04/elementary Luna/kernel 3.7.5) won't boot. It seems to hang after the modeset. I can get to recovery mode with the following kernel options: nomodeset recovery. A Fedora 23 MATE Live CD/DVD seems to hang right after finishing the initial bootup loading screen. I can get booted into a Clonezilla Live CD, but I can't get into either my installed Linux or a new Fedora. In the Clonezilla kernel log, I see that ata8.0 fails to initialize, saying that an IDENTIFY PACKET FAILED or something along those lines. This makes me think that either there's something wrong with the SATA port, the SATA cable, or the Blu-Ray/DVD reader device. Windows 7 on the same machine boots just fine and I can play DVDs in the device without issue. How can I debug what's actually going wrong so that I can fix it (perhaps with a kernel boot parameter)?

I would like to find a way to rip the WAV tracks (LPCM 2.0, 192kHz, 24-bit) from a Blu-ray Audio or a DVD-Audio disc using Linux. (Once extracted, it should then be a breeze to encode the audio tracks into FLAC.) Taking the TrondheimSolistene: Divertimenti Blu-ray disc as an example, how do you extract the WAV tracks?

I recently bought a Blu-Ray writer and am wondering how to best write the discs. The scenario is: I have a directory full of files and want to put them on the disc, read them back once to verify, and then put the disc on a shelf (i.e., the main purpose is for backup). Some of the files are bigger than 4.4GB or whatever the limit is for ISO filesystems. For writing to DVDs, I currently use growisofs, with split to break the files into bite-size chunks. growisofs doesn't seem to have good UDF support and splitting the files is lame, which is the motivation for my question. What is the current best practice for writing files onto a BD-R disc? I am on Debian Wheezy (Testing).
