#207 Batch files, black output

[gianluca]

If I open cmd.exe and paste this script it's ok

MediaInfo "--Inform=Video; %FrameRate%" ; originale.mp4 > framerate.txt

But I create a batch file whit the same info, mediainfo give me a framerate.txt without any information.

Note for me:
- batch does NOT like quotes and "
- MediaInfo --Inform=Video;file://Template.txt with Template.txt is a file with " %FrameRate" return the framerate, but with one garbage byte, I don't know why.

Note for ficofico :
I will not be able to work on it before 2 or 3 weeks :(

The solution to this is to wrap the parameters in TWO % characters, not just one. I took a wild guess on this. When using cmd batch files, FOR loop variables need to be enclosed by double %'s, and apparantly MediaInfo uses cmd style FOR loops.

E.g. MediaInfo "--Inform=Video;%%FrameRate%%" ; originale.mp4 > framerate.txt

Excellent news.
I do the parsing myself, and output the result.
Maybe there is a problem with the Command line parser, i don't know, I didn't have time to work on this issue.
Thanks for the work around.

The use of double %-signs is required with windows command scripts.
This is an invalid bug.
