Playing dvd says "libdvdread: Encrypted DVD support unavailable"

Open 3N4N opened this issue 3 months ago • 2 comments

Important Information

- mpv version: v0.40.0-dev-g72dbcf119
- Platform version: macos 26.0.1
- Meson version: 1.9.1

Reproduction Steps

I wanted to build mpv from source because I wanted to play an external dvd with it (which is not supported with homebrew's mpv build). It built fine, but it couldn't play the dvd properly:

bash-3.2$ ./build1/mpv dvd:// --dvd-device=/Volumes/SCOOBY_DOO_2/
libdvdread: Encrypted DVD support unavailable.
libdvdread: Attempting to use device /dev/rdisk4 mounted on /Volumes/SCOOBY_DOO_2 for CSS authentication
libdvdnav: Can't read name block. Probably not a DVD-ROM device.
libdvdnav: vm: dvd_read_name failed
libdvdnav: DVD disk reports itself with Region mask 0x00fe0000. Regions: 01
libdvdnav: Suspected RCE Region Protection!!!
[dvdnav] Selecting title 0.
[dvdnav] DVDNAV, switched to title: 1
[ffmpeg/demuxer] mpeg: probed stream 0 failed
[ffmpeg/audio] ac3: exponent 25 is out-of-range
[ffmpeg/audio] ac3: error decoding the audio block

Expected Behavior

I realized the issue was the libdvdcss wasn't linked to the binary (even though it was installed):

bash-3.2$ otool -L ./build1/mpv | grep dvd
        /opt/homebrew/opt/libdvdnav/lib/libdvdnav.4.dylib (compatibility version 4.0.0, current version 4.0.0)

So I checked the meson build file and saw that indeed libdvdcss isn't listed as a dependency. In Linux, it's probably a dependency of dvdnav, but in macos, it isn't:

bash-3.2$ pkg-config --cflags dvdnav
-I/opt/homebrew/Cellar/libdvdnav/7.0.0/include -I/opt/homebrew/Cellar/libdvdread/7.0.1/include

In the end, adding libdvdcss as a dependency solved the issues:

diff --git a/meson.build b/meson.build
index e37564b03455..6dd9679cff50 100644
--- a/meson.build
+++ b/meson.build
@@ -637,9 +637,11 @@ dvdnav_opt = get_option('dvdnav').require(
     error_message: 'the build is not GPL!',
 )
 dvdnav = dependency('dvdnav', version: '>= 4.2.0', required: dvdnav_opt)
+dvdcss = dependency('libdvdcss', version: '>= 1.2.0', required: dvdnav_opt)
 features += {'dvdnav': dvdnav.found()}
 if features['dvdnav']
     dependencies += dvdnav
+    dependencies += dvdcss
     sources += files('stream/stream_dvdnav.c')
 endif

Actual Behavior

Now mpv plays the encrypted dvd correctly.

This is the output of meson setup build2 after I added libdvdcss as a dependency:

I carefully read all instruction and confirm that I did the following:

  • [x] I tested with the latest mpv version to validate that the issue is not already fixed.
  • [x] I provided all required information including system and mpv version.
  • [x] I produced the log file with the exact same set of parameters, and conditions used in "Reproduction Steps".
  • [x] I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
  • [x] I attached the full, untruncated log file.

This issue is solved for me. I just wanted to repot it here in case the maintainers want to address it in the source. Otherwise it can be closed. Thank you guys for mpv.

from IRC so it's not lost.

22:59:37 kasper93: der_richter: does macos bundle copy libraries? 23:00:02 kasper93: I don't understand why adding dvdcss to mpv fixes it for them 23:00:14 kasper93: but maybe without it, the .so is not visible by dvdread? 23:01:29 der_richter: it should bundle all libraries linked to the binary and its depencies 23:01:41 der_richter: besides the system ones, or rather the ones we exclude 23:02:29 der_richter: https://github.com/mpv-player/mpv/blob/master/TOOLS/dylib_unhell.py#L11-L25 23:05:52 der_richter: yeah it's probably not visible to dvdread, eg the bundle operates in an environment that's different from your shell. 23:08:26 der_richter: *dependencies 23:11:10 kasper93: dvdread opens dvdcss with dlopen() so the bundle script probably just doesn't add this lib 23:11:30 kasper93: and they workaround this by linking dvdcss directly to mpv making bundle pull this lib 23:12:06 kasper93: we could have specific inclusion if (dvdnav) include dvdcss in dynlib script 23:13:47 der_richter: how does it dlopen it? or rather how does it get the base path? 23:15:12 kasper93: https://code.videolan.org/videolan/libdvdread/-/blob/master/src/dvd_input.c?ref_type=heads#L468 23:16:06 kasper93: it is also possible to link it statically, but this require libdvdread rebuild 23:17:35 der_richter: i could possible set a env var so it can find it in the standard paths 23:17:47 der_richter: https://developer.apple.com/library/archive/documentation/System/Conceptual/ManPages_iPhoneOS/man3/dlopen.3.html LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, and DYLD_FALLBACK_LIBRARY_PATH 23:20:20 der_richter: https://github.com/mpv-player/mpv/issues/17032#issuecomment-3523365097 though probably not DYLD_LIBRARY_PATH XD 23:22:33 der_richter: https://github.com/mpv-player/mpv/blob/master/osdep/mac/app_hub.swift#L62-L67 we already do some special PATH manipulations for the bundle anyway 23:27:12 der_richter: though no idea if it might be too late. to current man says "was set at launch"
