VLC 3.0: "cannot access bluray:///media/cdrom1"

[Jason_25]

I have a media computer dedicated to playing bluray discs that runs Devuan Linux with Alsa sound. I have been running into this problem: https://trac.videolan.org/vlc/ticket/10422 . There are no backports available and all permutations of all workarounds have failed resulting in continuing stutters. So I have decided to compile VLC 3.0 from git.

Without contribs, the compile finishes successfully. When trying to play a disc the player stalls for a few seconds and gives the above error.

With contribs, the compile fails like this problem: https://trac.videolan.org/vlc/ticket/17 ... num_hist=1 . When I compile without libarchive, the compile finishes successfully. Unfortunately, when trying to play a disc the player immediately gives the above error.

There are no error messages in the console besides the above error. All VLC settings have been reset to defaults. Could the lack of libarchive be causing playback problems now? Where can I troubleshoot from here?

No, this has nothing to do with libarchive, more likely something do do with Bluray libraries.

Thanks for the reply. I have some good news and some bad news.

The good news is I fixed the problem by running apt-get build-dep vlc on the computer with the problem. It was not the computer that compiled the program so it needed some dependencies. I also was able to see undefined symbol errors in libbluray by increasing the log level in the messages box which is what lead me down the path to fix the problem.

The bad news is the "ES_OUT_SET_(GROUP_)PCR is called too late (pts_delay increased to 300ms" bug is still present, which is why I upgraded in the first place. For example, this starts happening around 5-7 minutes into "The Martian". Yet the rest of the movie played perfectly as I did not touch the controls at all. Previous experience has shown that if you do rewind you will bring on constant stuttering symptoms. I did not want to ruin that movie with more troubleshooting. I plan on watching several more bluray discs soon and I will report back if I have anything useful to add.
