Can't compress because No Title Found

Post by MickM »

I'm running HandbrakeCLI (the nightly build from May 10, 2021) in a script to convert tons of TV episodes from VIDEO_TS format to mkv. I'm on a Mac and I've tried this on both Catalina and Big Sur and have the same issue. For the most part everything is working fine, however every now and then I notice one of the TV episodes just won't convert. There seems to be nothing wrong with the source file in that it plays without issue, it's just that HandbrakeCLI (and also the GUI) simply won't process it.

Any idea what's going on? I can make the episode available on dropbox if you're interested. Here is the output when I run it in the CLI via my script:

I should also mention that the source of the VIDEO_TS structure came from ripping my DVD with MDRP (MacDVDRipper Pro) which removed the encryption at the time. That was done years ago (well before I figured I'd never fill up my NAS) and I no longer have the DVD itself to try re-ripping it or do any other experiments. This issue isn't specific to a particular TV series, it's more of a random thing here and there. Either way, all of the VIDEO_TS packages play perfectly in VLC or in DVDPlayer on the Mac.

Can you open the rip with makemkv?

Try ripping to a video file instead of a VIDEO_TS structure with MakeMKV instead. There are other challenges with VIDEO_TS other than just encryption.

rollin_eng: I just tried MakeMKV and it was able to process the file and I created an mkv that plays just fine.

mduell: I'm not ripping to a VIDEO_TS structure, my source material is an unencrypted VIDEO_TS structure.

My main issue is debugging why a very small percentage of my source material is just failing in Handbrake when it plays perfectly in all of my media players.The goal is to fix why Handbrake isn't behaving robustly.

Most (all?) HandBrake developers don't really have time for that and/or prefer to work on other features.

DVDs can have broken/bad structure and/or authoring.

If a DVD is giving you issues rip to mkv with makemkv to try to remove such issues.

OK - thanks. I'll take the MakeMKV followed by Handbrake route then. I just thought it might be an easy fix given that the terminal output first indicated it found a title but then later on said it couldn't.
