Blu-ray iso "No Title(s) Found"

Post by simonmcnair » Fri Mar 16, 2012 8:55 am

Hi,
I tried opening an unencrypted blu-ray ISO with HB and it came up with a "No title(s) found" message. This was ripped using anydvd HD 7.0.0. I'm sure the iso is fine as I can mount it using OSFMount and then handbrake will read it perfectly and powerdvd8 plays it.

Indeed.

Unlike libdvdread, libbluray doesn't mount ISO images, so you need to mount it first.

Rodeo,
Thanks for the brilliantly clear, informative and prompt reply.

So should I put a feature request in to ask for a more informative error rather than the ambiguous/erroneous error ?

cheers

What did you have in mind? HandBrake can't recognize the file. It can't tell you to mount it because it doesn't distinguish whether it is a mountable file type. It only knows that none of the libraries HandBrake uses were able to find video in the file.

Hi John,

I suppose for me a helpful error may state "No title(s) found. Please note that Handbrake cannot open unencrypted bluray isos". It would only do this in the case of an ISO file and generally I think an iso would be of a DVD or bluray ?

just an idea.

HandBrake doesn't look at file extensions, only the contents. So it doesn't know it's an ISO image.

Okay. Point made. There is no way on this Earth that this error message or error code handling could be improved.

I was just trying to say that Handbrake works in two different (undocumented afaik) ways depending on if a source ISO is bluray vs dvd and that this may cause confusion and that I could not find any way of answering or resolving this problem without resorting to the forum. Now that I've posed the question and you've explained the reason there is nothing that can be done to remedy the situation.

That's fine. It really is. I've got my answer so I'm okay ;-)

ps. Surely handbrake does know it's an iso, since you have the filename + extension that's being requested. Just because you don't currently use it (apart from to pass to a function) that doesn't mean it couldn't be an enhancement ?

Cheers
Simon

Well, HandBrake doesn't know, but it could be modified to guess the file type based on the extension. Not sure whether it's a good idea. Patches welcome.
