DVD playback issue

    Recently I updated my system to LibreELEC-RPi4.arm-11.0-nightly-20220903-97c088f

    and later on I also verified this issue with a complete new vanilla installation w/o any custom Add-Ons installed nor any custom settings.

    When I try to play back a css-DVD on that machine, the DVD starts rotating, then the rpi works for a while on it (blue moving circle shown on display) and then falls back to the main menu.

    I tried it with three different DVDs and I can verify that in July, DVD playback worked great with the very same components and libreelec.

    I also updated the kodi log here.

    If you have ssh access, you can increase libdvdcss debug this way:

    Code
    systemctl edit kodi.service

    then in the editor add:

    Code
    [Service]
Environment=DVDCSS_VERBOSE=2

    then run systemctl daemon-reload and systemctl restart kodi.service.

    Retry your DVD and check in /storage/.kodi/temp/kodi.log the log fro libdvdcss errors.

    I have the same issue except I have no July image to test against. I doubt this is a kodi/libdvdcss error per even if I hack libreelec build to build against upstream videolan libdvdcss also fails. (mind that I tried on ubuntu image with kodi - 18 as the ubuntu image is old, ie focal - and libdvd-pkg libdvdcss on the same odroid c2 arm64 box, same DVD, same drive and it works).

    Do you have a libreelec commit that works (ie from July) so I could build it?

    Also on amd64 kodi 20 and 19 both decrypt correctly this DVD with libdvdcss on the same drive (external usb one).

    The debug log I get with the above DVDCSS_VERBOSE=2:

    (...)

    ie none of the key get decrypted

    Thank you for your reply and sorry for my late response, abws.

    The below listed weblink to the image from June can play DVDs, I tested it today.

    Code
    https://upload.uni-jena.de/data/6355ba7f2f2937.24058939/LibreELEC-RPi4.arm-11.0-nightly-20220618-b78941a.img.gz

    The current nightlies from October however show this error with the same DVD on the same setup in verbose-mode:

    daniel235 so it worked fine with 2022 June 08 build of b78941a?

    If that build worked fine, then the question would be if pull #6673 caused the problem. That was merged 2022 July 08. So try something just after that. Something like

    https://test.libreelec.tv/11.0/RPi/RPi4/LibreELEC-RPi4.arm-11.0-nightly-20220709-6050346.img.gz

    Then to confirm that pull is the issue, try the build just before

    https://test.libreelec.tv/11.0/RPi/RPi4/LibreELEC-RPi4.arm-11.0-nightly-20220707-379df42.img.gz

    If it is that pull, then it will need to be dissected some as there are a number of changes included in it, library and Kodi changes.

    Hello smf007

    thank you for your recommendation. I tried out several nightlies to figure out when it happened:

    7-09

    7-14

    7-18

    7-19

    7-20

    The above listed nightlies all could play DVDs on my rpi4

    7-23-0008ab5

    7-30

    9-03

    11-15

    These nightlies do not play (dvdcss-) DVDs anymore.

    There are no further nightlies available between 7-20 and 7-23.

    There are several commits listed for the time between these three days, including rpi upates.

    Thanks.

    The builds versus hash in order of commit history are:

    Build dateHash
    20220720 (works)3a4dc81
    20220723 (broken)0da8a26
    20220723 (broken)0008ab5

    In order of commit, the Pulls covering that range are:

    3a4dc81 Pull #6717

    1182c1a Pull #6721

    13bb8f3 Pull #6724

    06fd018 Pull #6715

    2cc0585 Pull #6726

    771b9b9 Pull #6470

    f529cc9 Pull #6727

    0da8a26 Pull #6729

    0008ab5 Pull #6730

    None of them are obvious as to breakage. If you were able to build Libreelec yourself, I would probably start by looking at #6727 as that appears to have triggered issues for others as well.
