[FFmpeg-user] ffmpeg / quicktime ref

[Johannes Ramson]

Hi,

iam trying to feed ffmpeg with quicktime ref clips made by avid on a
windows based system.
Unfortunately ffmpeg cant get the path from the clips, that the qt-ref is
pointing to.
Here is my output:

"C:\Users\TTVavid1\Desktop\qt ref test.mov"

C:\Users\TTVavid1\Desktop>set CURRENTDIR=C:\Users\TTVavid1\Desktop

C:\Users\TTVavid1\Desktop>REM C:\TOOLS\ffmpeg\bin\ffprobe
"C:\Users\TTVavid1\Des
ktop\qt ref test.mov"

C:\Users\TTVavid1\Desktop>C:\TOOLS\ffmpeg\bin\ffmpeg -i
"C:\Users\TTVavid1\Deskt
op\qt ref test.mov"

At least one output file must be specified

I already tried the "use_absolute_path 1" option without any success and i
wonder why the path is stored without any driveletter inside the qt-ref.

Is there a way to force ffmpeg to get the path in a "windows-like-style"?

The qt-ref file can be found here:
