Baywatch BD/UHD -> "please file issue"
Hi @domyd ,
when I try to demux the TrueHD stream from the extended version of "Baywatch" (2017), the summary states "please file issue". This happens for the Blu-ray and UHD alike.
Since this is the movie I first recognized the problem and got the issue started with LAVFilters, I would have expected it to have to remove some part of the audio at almost each segment change, but it only did so once. Please let me know if you need further information to investigate this.
Can you re-run it with -vv and post the output?
Tip: if you run it in powershell, you can do
mlp ... -vv > output.txt
to write the log to a file instead of to the console.
Thanks!
That's a very interesting disc. I've looked at the segment boundaries and 13/15 don't match at all. 1 of them is a perfect match, and that was removed. And the last one is actually a match, but the audio is offset by about 4 samples:
Looks like I'm going to have to get this disc to figure out what's going on there.
I imported it from Italy (https://www.amazon.it/Baywatch-Blu-Ray-4K-UltraHD/dp/B072FP6TBN/), but I guess the UHD disc is the same in Germany / Austria, since there's a german audio track on it. The Blu-ray in that package does not have german audio, so there might be some differences if you get a Version from Germany or Austria.
Just in case, I also made logfiles from the cinematic version. When I checked all the branching points in a muxed MKV, I did not encounter any problems with the cinematic version. So this might be interesting as well. Baywatch_UHD_Cinematic_output.txt Baywatch_BD_Cinematic_output.txt
Thanks! I'll be taking a look at that disc as well.
It's the 2 in 1 disc, I completed the muxing process and there were noticeable breaks in the audio
@domyd I've just tried Cars UHD which has 95 segments and has noticable breaks in the THD during playback from a file made with MakeMKV. All is good! Here is the log if you would like to have a look:
Sorry, are you saying you have issues with the Cars THD generated with mlp, or are you confirming that it works as advertised?

Both Midway and Knives Out are Lionsgate discs with obfuscated playlists and Screenpass
I get the same output for my Knives Out disc. That's really odd, it looks like the A/V sync should be a good half second off around the middle of the movie. Thanks for reporting it, I'll see what's going on there.
@dastardo What does that obfuscation look like? Can you give me some more info on that?
Obfuscation as in the file is broken into segments and they also add a fake playlist to try and add further confusion.
Another one for you @domyd Are you still looking into this issue? It's Resident Evil Apocalypse
Thanks for the report. I haven't gotten around to figuring these out yet, hoping to do that soon™ ... I'm also running low on disk space 😄
I've investigated the Knives Out issue, and it seems that mlp indeed produces bad output for that disk (and presumably for all "please file issue" disks). The TrueHD streams are actually about 1000 samples shorter than the video segments, according to ffmpeg. But, MakeMKV somehow magically finds the missing audio (and it is legit, it's not just copied to fill the length or something) and gets a correct demux. So for now, until I get to the bottom of this, I'd suggest using MakeMKV for disks where it says "please file issue" at the end.
Good to know you're still looking into it @domyd. I have been using DGDemux as I find it is much better than MakeMKV. I quite often get dropouts and sync issues with MakeMKV whereas I don't get as many issues with DGDemux, Cars demuxed with MakeMKV is terrible with constant breaks and dropouts.
Interestingly even DGDemux cannot achieve a correct demux for Apocalypse Now or Resident Evil Apocalypse. DGDemux is successful with Knives Out and Midway though. If you need any samples from DGDemux just let me know.
dastardo, can you explain the issue with DGDemux and Apocalypse Now or Resident Evil Apocalypse? I can have a look at that and try to fix it.
@videoh There are breaks in the TrueHD and it goes out of sync, IIRC it only happens on the extended version of Resident Evil Apocalypse, it's a 2 in 1 disc but the theatrical version seems to be OK. I believe both the theatrical and redux versions of Apocalypse Now have the issue, it is also a 2 in 1 disc.
Thank you. How far out of sync does it get by the end? I will get Apocalypse Now and see if I can duplicate the issue. Is that the bluray or UHD version I should get?
I would guess it goes a good couple of seconds out of sync so you will definitely notice it. You need the UHD 2 in 1 disc which has the theatrical and redux versions. There is also another UHD disc which is the final cut only, there are no issues with that disc.
I cannot find an Apocalypse Now UHD 2-in-1 with theatrical and redux on amazon or elsewhere. I can only find the Final Cut. Can you give a link to purchase it?
Thank you for all your hard work! It's a great piece of software!
Could you please reply on this thread if you manage to fix it?
Of course I will. domy's github has been open in my browser for months. :)
And thank you for your kind words.
