v19 Libbluray full menu's and seamless branched UHD and Blurays cause problems
#1
good evening all, i will supply a log tomorrow and a video to show it better but wanted to get the thread going

I have noticed an issue with how Kodi handles seamless branched UHD Bluray rips(i think they are called seamless branched, the issue is not presant when playing the movie in main movie mode, but when Menu's are enabled they cause frame skips and audio drop outs when the seamless branch files switch over, movies i know it happens on so far is The Phantom Menace, Attack of the Clones and Dark Pheonix, the seamless branched files on the star wars is used i believe for the subtitled parts so the user selected language can be shown

i have tested the rips with VLC and the playback is as expected, i have tired the lastest nightly and both the HDR branches of Kodi and the issue is there, not tried a 18.6 but i dont think that can do UHD menu's

have installed a default nightly for V19 and both logs i have created playing with menu's and without menu's are 7meg and every paste site craps out with the size can anyone offer assistance here?

other info i can supply currently is when playing with menu's when it gets to the .ts change the buffer icon appears on screen using the default skin

After some more reading it might not use seamless branching but could be using multi-angle

Going to see if I can find some blu rays that do it also or if just a UHD problem

I also tested coreelec on a box I have here and same problem

Wow not even a reply from anyone saying they work for me or I spotted something in the log or a tip to try or just even tell me to go away would be nice

Well UHD Bluray playback is probably still quite niche. Are these issues only with UHD rips? do you have normal HD Bluray rips and are they all ok? It could be that libbluray is still immature with it's UHD support.

Thank you Smile

I was going to spend sometime this week to try and find normal Blu-ray rips with the same structure

Just frustrating the crap that is VLC played them Sad

have just found it does it with X-men days of future past the rogue edition which is a standard blu-ray rip, i have not found a jump/skip/audio drop as bad as Phantom menace yet but that could be blu-ray versus UHD but the issue is presant when another file is called to either an extended scene or subtitles kodi glitches and skips/glitches/drops audio VLC does not and plays flawless

VLC uses libbluray as well as it's produced by some of the VLC devs so it's an associated project. Do you happen to know what version of libbluray your version of VLC is running? it seems we are using v1.1.2 in current Matrix nightly builds.

The version I have installed is using libbluray 1.2.0

tried a quick hack also, copied over the newer version and renamed to 1.1.2 although the movie plays i have no keyboard control so can't get past the language selection screen

Looking at the VLC repo it seems v3.0.8 was the last version using libbluray 1.1.2 see https://code.videolan.org/videolan/vlc-3...les.mak#L3 that changes to 1.2.0 for VLC 3.0.9. It would perhaps help to identify if your issues are caused by libbluray v1.1.2 if you were to try VLC v3.0.8 to see if you have the same issues. If VLC 3.0.8 works thus making it more likely to be a Kodi issue then I don't see a short term fix as there is no one currently active on this area of the code, if however VLC 3.0.8 also exhibits the same issues then that makes it more likely it's an libbluray 1.1.2 issues so these problems maybe solved when the libbluray version is next bumped in Kodi.

it might be a cacheing issue as i first suspected and tried to give 4gig of cache to kodi as was a uhd but it seemed to have zero effect on anything i played

Thanks for trying that, so it seems more likely to be an issue with Kodi then, and unfortunately that means there's not much I can offer in the way of help. Could you log the issue formally at https://github.com/xbmc/xbmc/issues and maybe someone will take a look, unfortunately there's only limited active devs at the moment, but perhaps it might draw the attention of someone if only to confirm they see the same issue so not something unique to your system. When doing this post your log file there together with all the testing info from this thread, as we have an automated bot validates if new issue are properly structured using our issue report template.
