Already fixed, but not in the latest source release, right.

depends of what you are looking for.
1/ just add the option in the GUI: a couple of hours. Fact is that I do not want (at least for free) to update the current GUI because I plan to trash it (yes, I say that for years...) and I am not myself interested in letting people easily complain about "ho this is not exact value if I set full parsing, despite the fact I set full parsing so you should be able to provide the right value, MI is bad", see 2/.
2/ having exact value for lot of things (e.g. you want the exact byte count for MKV): this is not implemented everywhere, I have no idea about what works and whats does not work, I need a complete test of each item, lot of test several days/months. Currently I implement full parsing improvements item per item, when a user really (= he is ready to pay for it) need a feature (and in that case, he know how to activate full parsing for having his feature).

You can already test the current behavior with CLI or DLL (" -- ParseSpeed=0" for fast parsing and " -- ParseSpeed=1" for full parsing). There is absolutely no promise that MeidaInfo will do what you expect it does.

That's good to know, and I might start using that in a few specific instances. Also good to hear that mkv parsing is going to be expanded soon.

Hello.

No MediaInfo information for this file:

https://www.sendspace.com/file/xp31p6

[manolito]

The file is broken somehow...

TSDoctor complains about a missing PMT and refuses to repair the file. Remuxing to MKV (MKVToolNix) or remuxing to another m2ts (tsMuxeR) fixes it.

Manolito, Zenitram thank you both for your replies.

[73ChargerFan]

I use the command line interface to prepare MI reports on my files, using a DOS batch file ( )

I'd like to request a feature, to report the current directory name. I use the directory name as the reader friendly primary identifier, not the file name, and merging that information from the DOS batch file is extremely difficult.

Thank you for all your hard work.

current directory name?
What is the relationship with MediaInfo?
http://www.windows-commandline.com/b...ent-directory/

If you want the directory name of the file you are analyzing, you can use the full output (" -f") or put %FolderName% in hte "General" section of a template

Also, if the full path to the file you are analyzing is in variable %i (or %1) of your Batch file, you can simply use %~dpi (or %~dp1) to get only the drive+path part.

[73ChargerFan]

My goal is a create a CSV to import into Excel, where each line is the folder name (user readable) and the major stats. MediaInfo can do all this except the folder name.

%FolderName% gives the complete path, but I want only the current directory.

Currently I use %~dpi (or %~dp1) but to get it into the same text line I must use a placeholder token in the MediaInfo format string, then do a text substitution by separate program. Problem is special characters in the path mangle and foul up batch file variable substitution and delayed expansion. Basically I've got most of a day into a hack that fails silently 2% of the time. This would be so much easier in Bash...

I know this is a special use case. Thank you for the assistance and suggestions!

Please provide an example because I don't understand the difference between %FolderName% and "current directory".

Been there, done that, batch files are horrible for this. So much cleaner using sed/awk from unixtools, PowerShell, vbscript, or your favorite installed scripting language to pare the full path down to just last folder\file.

I wrote a small guide regarding MediaInfo and StaxRip in case somebody is interested:

Sorry for the late reply.

Example (1) %FolderName% gives complete path:
"Z:\Media\Kids\Kids 2\DC Batman, Superman\DCAU\Batman Beyond\"

Example (2) Current Directory: "Batman Beyond"
is the show title, and the directory has 50 +/- episodes named by episode number & episode title, but not including the show name.

@ foxyshadis

I am curious how using sed/awk from unixtools, PowerShell, vbscript or any other scripting language would make it any easier to extract the string "Batman Beyond" from the full path variable compared to using a simple batch file.

Yes, I would need a loop to determine the positions of the "\" characters, but I could write the batch file in 2 minutes. Please give us an example how you would do it with any of the tools you suggested.

I do have a little experience with SED for Windows, it is a pain to learn the syntax, and the result is "Write Only", without comments it is unreadable. And the learning curve for PowerShell or VBScript is also steep for someone who grew up with Turbo Pascal, MASM and DOS Batch language.

Should be straight forward to get it with a regular expression.

This gives you the last (rightmost) directory part within a full path, assuming there's a trailing backslash:
\\([^\\]+)\\$

If the path may end with file name, you can use:
\\([^\\]+)\\[^\\]*$

Now please don't ask me how to translate that to proper SED syntax

[ndjamena]

Powershell:

$TargetPath="Z:\Media\Kids\Kids 2\DC Batman, Superman\DCAU\Batman Beyond\Boo.txt"

[System.IO.Path]::GetFileName([System.IO.Path]::GetDirectoryName($TargetPath))

It's mostly the '\' at the end of his example that's the problem. '/' is also a valid directory separator and "\\"... unless you know exactly where the filename will be sourced from you'd need to add some error correction into the mix.

Of course as far as I'm aware MediaInfo doesn't add the extra slash to the path name so

$TargetPath="Z:\Media\Kids\Kids 2\DC Batman, Superman\DCAU\Batman Beyond"
[System.IO.Path]::GetFileName($TargetPath)

will do.

(Powershell is a PITA, I prefer to use batch when I can get away with it.)

-Edit-

$TargetPath="Z:\Media\Kids\Kids 2\DC Batman, Superman\DCAU\Batman Beyond"
[System.IO.Path]::GetFileName($TargetPath).Trim('`"').TrimEnd("/\")

[73ChargerFan]

Sorry this is so off topic, I just think it's a good idea. But this will be my last post on this.

Even with the above code, I still have to capture the 1 line output of MediaInfo into a temp file, do a text substitution (which isn't free on Windows), then append that temp file onto the text file, which is another inner loop, and ...

This is what I get from my code, which loads directly into Excel.
First field is the Current Directory, next is file name, then size, file type, classification of video (done manually), video summary, main audio stream info, then finally the directory all the movie directories are in (this last matches the name of the backup hard drive the file is copied to.)

(g)awk is more suitable for this than sed, really.

Given "Z:\Media\Kids\Kids 2\DC Batman, Superman\DCAU\Batman Beyond\", it would only take:

awk -F'\\' '{print $(NF-1)}'

Which prints the second-to-last column (Batman Beyond), determined from the \ character delimiter.
