[Solved] How can ffmpeg extract frames to a target dir (%T)?

[sorcar]

Is there a way put the target directory variable (%T) in the button bar "Start Path"? Putting a directory path in the "start path" seems to be the only way to get FFmpeg to send its output to a specific directory.

What exactly are you trying to do with ffmpeg?

This works fine for example:
Command:

Code: Select all

%comspec% /k c:\Tools\ffmpeg.exe

Parameters:

Code: Select all

-i "%P%O.%E" "%T%O.avi"

What exactly are you trying to do with ffmpeg?

I am trying to extract JPEG frames from an .avi file. I am using,
Command:

Code: Select all

%comspec% /k c:\Tools\ffmpeg.exe -vf fps=1/60 -qscale:v 2 image_%04d.jpg

Parameters:

Code: Select all

-i "%P%N"

The frames get extracted in the same directory as the input file (ie, at %P). But if I add a fixed path in "Start path:" (such as c:\test\frames\), the frames are extracted there. "Start Path:" does not seem to take %T, and I haven't found a way to extract to the target pane.

Got a way out! The desired effect can be had with:
Command:

Code: Select all

%comspec% /k c:\Tools\ffmpeg.exe -vf fps=1/60 -qscale:v 2

Parameter:

Code: Select all

"%T\image_%%04d.jpg" -i "%P%O.%E"

The problem was because of ffmpeg having no switch for output folder.

Thanks, ZoSTeR, for your useful suggestion which gave me the idea.

Glad it worked. You can put everthing in the parameter:

Code: Select all

-i "%P%O.%E" -vf fps=1/60 -qscale:v 2 "%Timage_%%04d.jpg"

Works like a charm. Thanks a lot, ZoSTer. It further simplifies the matter.
