Media Duration Cannot be Found (Windows) #4

Closed CallumKerson closed 9 years ago

CallumKerson commented 9 years ago

Description

Whenever I try to transcode any mkv file, it parses the parameters, then the following message is printed out.

/home/Callum/bin/transcode-video: media duration not found

This happens regardless of the parameters or input files. It happens for all kinds of mkv inputs. I cannot find an mkv that works.

Environment

lisamelton commented 9 years ago

Callum,

Thanks for the report. Sorry it's failing like that. I'm trying to get a VirtualBox install of Windows 7 up and running so I can reproduce this.

CallumKerson commented 9 years ago

You are a star. Thanks so much. Let me know if you need any more from me.

lisamelton commented 9 years ago

Well, I may have to buy a PC because VirtualBox keeps locking up on me. :/

This may take awhile.

lisamelton commented 9 years ago

Ugh. I've spent the last three hours waiting for Windows 7 to updated itself. Can't do anything until it's done. This reminds me why I use OS X. :/

command-tab commented 9 years ago

I've got a Win7 SP1 x64 VMware VM handy. I could try to reproduce the issue if you like.

lisamelton commented 9 years ago

Oh, thank you, @commandtab! Please, yes, oh please!

command-tab commented 9 years ago

On it.

command-tab commented 9 years ago

Current status: Going to get a drink while ffmpeg builds.

Excellent! That better be good wine. :)

command-tab commented 9 years ago

Alright, I think I've got everything set up, but when I run transcode-video ~/title.mkv, I get:

transcode-video: scanning media title 1 failed

Same output for detect-crop. @donmelton Do you recognize that as a script issue, HandBrake issue, or something else entirely?

command-tab commented 9 years ago

Interesting, this little hangup may be the result of an issue with HandBrakeCLI. Using the simplest of HandBrakeCLI (0.10.1) commands, it won't recognize any formats. Here I'm attempting to encode an MKV of a DVD using the MPEG-4/AAC defaults:

CallumKerson commented 9 years ago

I can get it to start transcoding with the Handbrake CLI as above. The issue you have to watch out for with this stuff it paths. If you are passing it a path like ~/POSV.mkv then the windows Handbrake CLI exe doesn't know what to do with it. I'm not completely sure of the way around it, but I pass it a path to my network share that is the same in both Windows and Unix, like //192.168.1.16/Nalthis/Media/Videos/Archive/Princess Mononoke 1997.mkv. The scripts AND handbrake will recognize such a path.

CallumKerson commented 9 years ago

Ok I have found the line where the problem comes from

It is trying to find the duration from the scan command, which is at

It is trying to construct the command using the following code:

begin
    IO.popen([
      HandBrake.command_name,
      "--title=#{title}",
      '--scan',
      "--previews=#{previews}:0",
      "--input=#{path}"
    ], :err=>[:child, :out])

I have constructed a similar command myself, using

 HandBrakeCLI --title=#1 --scan --input="//192.168.1.16/Nalthis/Media/Videos/Archive/Princess Mononoke 1997.mkv"

and this works! I get a duration out of it, Duration: 02:13:21.99. The full output of that command is below. So I do not beleive it to be a Handbrake problem. Either the output is not being parsed properly for that duration information, or the code is hitting line 74 without doing the scan method.

I believe it may be the latter option, as line 273 in the scan method has the statement Console.info "Scanning #{label} with HandBrakeCLI..." and I do not see any such output when I run the scripts.

Hope this is helpful.

lisamelton commented 9 years ago

@commandtab Thanks so much for doing all that setup work! Sorry I didn't comment last night but I collapsed in bed at about 10:30 here in California. Looks like you're reproducing the same problem, or something very similar, that @CallumKerrEdwards is having.

Based on all the data from both of you, I would say the bug is somewhere in my code, probably in parsing the scan output of HandBrakeCLI in the media.rb file. There's just something fundamental I'm doing that doesn't work on Windows. But I don't know what that could be yet.

lisamelton commented 9 years ago

OK, I have finally got enough of a Windows 7 installation working on VirtualBox to reproduce the "media duration not found" error. Let's see if I can figure this out...

CallumKerson commented 9 years ago

Thank goodness! I was worried it was an environment issue on my box 😔 let me know if there is anything I can do.

peelman commented 9 years ago

Normally I'm the first guy to say "you can't beat free" but in this instance, I can't recommend Fusion enough. Use it everyday, and it hard-won my allegiance from Parallels and VB. Super fast and very stable.

lisamelton commented 9 years ago

@CallumKerrEdwards I never doubted you! It was me that I was worried about. :)

@peelman Good to know. Thanks for the recommendation. Fast is what I need.

lisamelton commented 9 years ago

Ugh. I now know what the problem is and it's systemic. Ruby isn't recognizing DOS-style line feeds in regular expressions. :(

lisamelton commented 9 years ago

And it gets worse, too. :( The behavior of Cygwin and MinGW-based standalone Ruby installer are different.

lisamelton commented 9 years ago

OK, I'm slowly figuring out a patch for this. This could take awhile, but stay tuned...

lisamelton commented 9 years ago

Ugh, Cygwin is particularly stupid about handling $ in regular expressions when parsing input with DOS-style line endings. MingGW doesn't have this problem.

This means I'll have to change code in query-handbrake-log too. Just shoot me.

God-willing I don't have to change any of the command line option parsing code!

lisamelton commented 9 years ago

The good news is that preliminary testing indicates my patch to media.rb doesn't break transcode-video on OS X.

So I've got that going for me. Which is nice.

command-tab commented 9 years ago

@CallumKerrEdwards Good call on the paths! I'm able to use the method you suggested and am now able to reproduce the issue. So, I'm in a position to test a fix as well :)

lisamelton commented 9 years ago

@commandtab Sweet! I'll have something to text for y'all in (hopefully) about an hour or so.

My only problem is that I ran into a completely new bug (not Windows-related) while doing testing. Dammit. :)

lisamelton commented 9 years ago

OK, just checked in the fix! Whew! :)

As soon as I fix this other damn bug I'll push a new Gem. Stay tuned...

lisamelton commented 9 years ago

@CallumKerrEdwards and @commandtab The Gem has been pushed! Please test and let me know if this is fixed.

Thanks for all your help on this one!

I'll close this now but I'll re-open it if the bug is still happening for either of you.

CallumKerson commented 9 years ago

Verified!

lisamelton commented 9 years ago

@CallumKerrEdwards Hot damn! Now I'm can get some sleep tonight. :)

Thanks again!
