Demuxing MKV with 2 audio, 2 subtitle and 3 TTF attachments.

I ran some anime through VidCoder to compress the x264 video to x265. It did that very nicely. The source files have two audio tracks, two subtitle tracks and three TTF font attachments.

Vidcoder lost the second audio track but kept the subtitles and fonts. I didn't really care about compressing the audio more. MKVToolnix v20.0.0 will work with these files. I can drop the original file and the new file onto it and deselect all but the video track of the new, deselect only the video track of the original and remux. Hooray, I have a lot smaller file.

BUT, it will be very tedious doing all of that mouse clicking. :P So I figured I'll batch strip all but the video from the new files with MKVBatch 1.3.2. Nope! It does *nothing*. It goes through the motions, nothing lands in the output folder. I've used it many times to batch mux subtitles, but only with one audio and one subtitle track.

How about MKVExtractGUI 2.3.0.0? Nope! All it shows are the three TTF attachments and like MKVBatch goes through the motions, does nothing. Just checked some other MKV files that don't have multiple audio or subtitle tracks. If they have chapters that's all it shows. No chapters, it shows nothing to extract.

Did updating MKVToolnix break MKVExtractGUI and MKVBatch? Muxing single subtitles with MKVBatch into video with single audio tracks still works, I've used it for that since updating MKVToolnix.

Is your problem lost audio track? Understand you properly?
In vidcoder just add new track in audio tab, so instead of one track you will have 2 tracks.
But not sure I understand you properly.

Yes, mkvtoolnix 20.0.0 broke some tools (don't know about mkvbatch, gMKVExtractGUI didn't break). So either go back to 19.0.0 for this operation or do it via command-line.



P.S.: VidCoder can handle multiple audio tracks just fine. It also has "pass-thru" mode so audio isn't getting recompressed unless desired by the user.

I used gMKVExtractGUI to demux just the recompressed video, then MKVToolnix to replace the original video tracks with them. Hopefully the tools that have problems with 20.0.0 will get updates to fix them.
