Replay Gain Scan & MKV Problems

I have MKVs created with MKVTOOLS GUI and 2.98 (plus some 2.97) mkvmerge tools.

Typically, the include;
H.264 Video in Track 1
AAC/LC in Track 2
UTF-8 subtitle in Track 3
UTF-8 subtitle in Track 4
some with, some without chapter files.

It is very annoying as applying replay gain to the MKV works on some, but not others.

I get the following error
"Could not update tags (Unsupported format or corrupted file)"

Sometimes a complete extract and remux from raw files works, mostly not.
I can't pick any pattern to the ones that work and the ones that don't.

I am not sure if this is an issue with the mkv component of foobar2000 or a change from the mkvmerge.
But i can say, apply the gain with files created from 2.98 works for some and not others. So something else must be causing it.

most grateful for any help

there is definately something strange with fb2k 9.6.9

I find that right mouse clicking on the mkv and opening it in fb2k has a more reliable chance of of being able to add the replay gain.

For a file that already has the gain added. i have noticed that opening with this method producing intermittently different results. i.e. sometimes the gain settings appear in fb2k and sometimes not.
if they not appear and you perform a scan, you get the above error when trying to save.
if they do appear, you can remove and rescan and successfully save the settings

this is soooo bloody annoying.....every time i open the same mkv file, i get a different result .i.e.
- sometimes no replay info
- sometimes track replay info
- sometimes track-album replay info

I am talking about opening the very same file, but this equally applies to all my files......

FYI, i am using fb2k 9.6.9 on Win7 RC

Are you using additional component for handling matroska?
As of 0.9.6. the component isn't needed, and what's more it isn't recommended

i am using the inbuilt mkv support and i have managed to pinpoint the precise cause of the problem, but am not sure if it is fb2k's reading of mkv files or mkvmerge GUI's problem.

to replicate the problem; -

Working Method: -
- extract DVD chapter in OGG txt format
- mkvmerge gui add the chap.txt in the global options page
- load the mkv in fb2k
- notice, there are no Track numbers, only chapter titles
- now apply replay gain
- success

Failing Method: -
- extract DVD chapter in XML format or create chapters in mkvmerge GUI chapter creator
- add the chap.xml in the global options page
- load the mkv in fb2k
- notice, there are now track numbers and chapter titles
- now apply replay gain
- fails with the above error

Remuxing an MKV causes the previous "no track" version to have track numbers in the new output, and thus still fails.
only muxing with .txt version creates a format acceptable to f2bk

I couldn't figure out how to modify the XML file to ensure no "track number" was assigned.

I don't see any error trying your second method: I added XML chapters to MKV file with h.264 video and AAC audio and muxed it:

After that I successfully added ReplayGain info to AAC tracks (applying RG wasn't an option). Perhaps the problem is in the format of your audio file.
And the only problem for me and foobar MKV support is that it doesn't read dual audio streams - it reads only the first audio stream.

i am not clear if you are saying you;
- added the RG to the aac before muxing or after.

To be clear;
- one needs to mux AVC+AAC+SUBS+XML to MKV
- open MKV in fb2k
- RG Album
- Apply and the error "Could not update tags (Unsupported format or corrupted file)" is displayed

way to solve it is;
mkvextract chapters -s >chap.txt
remux with .txt file

it now works.

importantly, opening the MKV in fb2k produces two different results depending whether chapter source was .txt or .xml.
if .txt - there are no track number associations with the chapters
if .xml - there are now track numbers associated to the chapters

it's seems the issue is related to f2bk's interpretation of the file

although I did noticed now little glitch: I added MKV file with XML chapters and added comment (or any tag) to some track(s), then titles from all other tracks vanished

^[edit] of course I scanned after I muxed. And I don't have context menu option for "Apply RG" only "Scan RG" is available

RG - "Scan Selection as a Single Album", after the scan you select "apply" on the dialog.
You cant see RG with MediaInfo, you can only see it in fb2k but Media Player Classic recognises it

one more point to note; which further indicates fb2k.
(i use nero aac encoded 5-1 audio ABR 256K)

- when you use the method i state above (.txt) to add the chapters the status bar shows the kbps rate when the files plays in fb2k
- when you add the chapter info (.xml) way, the status bar shows ? kbps and can not determine the bit rate

so, i believe it is working for you. but it is not working for me on two separate computers and they both perform exactly as i have described above.

Could not update tags (Unsupported format or corrupted file) on:

"D:\Movies\A Few Good Men\1080p_A Few Good Men_1992_x264-dxva_aac-lc_en-cz.mkv" / index: 25

so where to go from here

I guess using txt instead XML

The problem in post #8 I guess is that if you change some tag with foobar, it writes it to "Global tags" in MKV and then it doesn't read XML chapter file, but switches to this Global tags entry, so any info from chapters isn't read but it exists still in MKV (it isn't deleted or anything)

i don't change/add any tag info. doing so, causes the RG to be lost. In summary, using the method that works, if i make any changes to the MKV, i have to go through the whole process of extracting the chapter as a .txt and then remuxing the whole thing again so i can re-add the RG.

Where is your RG info written in MKV file?

foobar writes RG info to "Global tags" entry
Adding/changing tags doesn't remove RG info and they are all written to "Global tags" entry
I can't imagine why you have this problems

The rest seems to look the same, but i can post the full files if necessary.

I'm not a developer for foobar matroska handling, so I can't help you except that I can try the same steps as yours and tell if the problem you have is reproducible.

Having 20 items in the chapter and 62 items in Global tags says that you have tagged every item from MKV file in foobar with 3 tags (3 x 20 + 2). That can be TITLE, RGTG and RGTP. Changing/adding tags doesn't remove RG values which are stored in Global tags as said couple of times.

And hey, try removing subtitles or any other attachments and see if it changes anything

not sure if i said this already, but;
- if you take a working mkv without chapters + RG
- use mkvmergeGUI to load and save chapters to the mkv file
- you can not longer see the RG in fb2k + the chapters have "track no" when read by fb2k
