Utility: Bluray MPLS Editor

[razrsharpe]

Bluray movies include a playlist (.MPLS) file to link to all of the video/audio/subtitle streams and to store the chapter information in. TS Muxer (great program) messes up the TIME_IN variable in the playlist and assigns it something other than 0 (usually 10 min). This causes Sage to not start the movie at Time = 00:00:00.000 and Chapter = 1. To fix this I wrote two small windows console applications.

readmpls
Like the name sounds this takes as input a .mpls file and outputs the TIME_IN, TIME_OUT, DURATION, and CHAPTER MARKERS.

fixmpls
takes as input a .mpls file and requests a new TIME_IN value. It then fixes all the timestamps in the file to reflect the new TIME_IN value. I always use TIME_IN = 0.00 secs, but can be whatever you want.

fixmpls creates a backup of the mpls file at runtime NAME.mpls.XX.back, where NAME = the playlist name, and XX increments from 01.

usage
fixmpls.exe [path to .mpls file] OR drag and drop a .mpls file onto the exe. I use a shortcut from the Send To: menu to send the .mpls to the exe

I found a bug in the way i was detecting the chapter marker in the mpls file that only happens very occasionally. With the corrupted .mpls file the movie crashed the HD200 requiring a hard reset. I discovered this on "Pride and Glory". It should be much more robust now. See below link to new file.

I'd like to make a chapter generator for mkvs, based on your program, but i'm stucked to decode the information from the mpls files, is there any chance to share the source code or share some tips about decoding tech datas from movie playlist file?
Thx in advance

yup that was certainly the tricky part.... If you open the .mpls file in a hex editor youll begin to see a pattern for where the chapters are defined in HEX. I ended up looping through the .mpls file byte by byte, creating a 4 bit unsigned int, and seeing if that was a valid integer to get the chapter breaks...

Just an FYI there are other tools out there that will output the chapter info for you (bdinfo, bdedit, tsmuxer, clown_bd (i think) )... The reason I dug into decoding the .mpls file directly is because i needed to modify the it....

I'm not at home right now but I'll see if i can dig up the souce and post it...

That would be great! Thanks in advance!

s4pp3r, what are you trying to do with your mkvs? I think makemkv already pulls the chapter information from the BD and includes it in the MKV file, so that may be your solution right there.

[razrsharpe]

here is the source that I use to read the mpls, determine the PTS integer (presentation time stamp), and convert it to Hour:Min:Sec.ms format... Good luck (note the only reason i converted the PTS from Hex to Decimal to HH:MM:Sec.ms is for display purposes...)

Yes, but i have some old mkvs without chapters in it, so its faster to get the mpls from the bd, then dl the whole disc only for the correct chapters

razrsharpe: thx the source!

Ahhh.. okay.. still, you may find it easier to use something like eac3to to get the chapters, then just modify the file to put it in the right format for mkvmerge, by hand...

ya my thoughts too.... decoding the mpls file was a major PITA and probably not worth it.... to automate you could write some batch type file to call eac3to, get the chapters, translate the chapters to the correct format, then insert them into the mkv with mkvmerge...

[s4pp3r]

Yeah i made it before

readmpls.exe %1 > chapter.txt
type chapter.txt | find "CH" > chap.txt
set /a num=1
@Setlocal ENABLEDELAYEDEXPANSION
for /F "tokens=3" %%I in (chap.txt) do (
echo CHAPTER!num!=%%I>>chapter-out.txt
echo CHAPTER!num!NAME=Chapter !num!>>chapter-out.txt
set /a num=!num!+1
)

But its not automatic, because you have to press any key coz its built in your program
I removed the while cycle and now its working correctly
CHAPTER1=timecode
CHAPTER1NAME=Chapter 1 ...
Thanks for your help!

Unable to download it, could reupload to other site. Thx! in advance!

attached is what i believe is the most recent version of this that i could find on my server. Note i have not used these tools in several years.
