Output Failing to Build

[ztrouy]

I am having an issue getting UnlinkMKV to provide a working output file. Using either the most up-to-date versions Strawberry Perl, MKVToolNix, ffmpeg, and other dependencies, or the versions specified in the readme, or those that are supplied with UnlinkMKV, I experience one of two issues.

When using default settings (more specifically everything but chapters and fixsubtitles being set to 0), the final result is "file failed to build". This appears to have something to do with the subtitles, as after unlinkmkv attempts to fix subs, it tries again "fixing subs, again... (maybe an mkvmerge issue?)". At the end of this, no output file is created.

When modifying the .ini to set fixsubtitles to 0, an output file is created, however, if you attempt to view it the video player says "Cannot render the file". Using a mix of fixaudio and fixvideo settings does not remedy the situation either.

Here are the full logs-

(Edit) I also tried setting "ignoredefaultflag" to 1, which produced a file that is watchable, but has no sound, and the video has heavy artifacting as well. Here is the log-

Any help getting this working would be much appreciated!

Please try it again with the "-ll trace" option so we can see what's going on

Did just that, to give you as much info as I could! I'll have to attach the .txt files, as they're really long and the styling on this website really messes with them.

If you need anything else, just say and I'll happily provide! IgDefFlag1.txt Sub0.txt Default.txt Aud1Vid1Sub0.txt

I suspect it's a problem with the subtitles, though I notice this release does appear to need the ignore default flag option. Try fixaudio+fixvideo+fixsubtitles(default)+ignoredefault.

If that doesn't work, toss me a link to where I can get these files to test with directly.

It completely failed to build a file sadly.

Here, I've uploaded what I'm working with at the moment, hopefully you have success in it, or find an issue that is causing it to fail!

Good luck!

I believe I tracked down the original encodes for this, the "hi10" anime group has released...questionable encodes before that I've had other reports for unrelated issues on as well.

The release requires --fixvideo and also --ignoredefaultflag, the problem is ffmpeg was bailing on the ending file and required the -max_muxing_queue_size option to be specified/increased from default. I uploaded a new version of unlinkmkv that updates the ini format and allows customization of the encoding settings, and also added that option to the default encoding settings. Make sure you update both unlinkmkv AND your ini file from the updated example ini.

Secondly, be mindful that this release has a decently-high quality at a low bitrate, while the unlinkmkv defaults are tuned towards higher bitrate files. Theres a good chance you'll want to tweak the encoding settings for the output to not look awful.

I do have a question, how am I to update UnlinkMKV? I understand how to update the .ini, however the executable is beyond me. The executable within the zip within the master zip shows that it was last updated in August, while the "unlinkmkv" file in the master zip is not an executable (I do apologize if I'm completely forgetting something)

Sorry, you mentioned StrawberryPerl earlier so I thought you were running from source. I updated the windows build in the dist/ with the new version now.

[ztrouy]

No worries! I'll check when I get home from work to see if it's all solved, then try and remember how to modify settings to get desirable results

Everything is working perfectly now! Thank you very much for your time and patience, it's much appreciated!
