MKVInfo doesn't return track info for some MKVs made by MakeMKV
Original reporter: ndjamena
I've been running into this problem occasionally for a while. I rip all my DVDs to the harddrive using MakeMKV and have a batch file that uses MKVINFO to get data that it then passes to MKVEXTRACT so that I can reencode the various elements. However, MKVINFO fails to properly read ANY of the actual track info from certain MKVs. It will happily read the Chapters and the Main File header but returns nothing about the Tracks inside. If I load the files with MKVEXTRACTGUI2 it also shows no tracks at all, just chapters, yet if I load the files into MKVMERGE everything's fine and I can continue as normal. VLC will play the files perfectly as well. It seems to just be an MKVINFO problem. The workaround I've been using is a straight remux of the files with MKVMERGE and retrying with the new file. There's a problem somewhere that needs to be fixed. I haven't figured out the FTP server yet, but if you need a sample I can try harder.
