Trying to use vidstab in ffmpeg I'm running into the problem that ffmpeg
doesn't parse my command line properly and I don't know how it should look
like:
When using:
{{{
"I:\Hybrid\64bit\ffmpeg.exe" -y -threads 8 -i
"F:\TestClips&Co\files\test.avi" -map 0:0 -c:v rawvideo -vf
vidstabdetect=result="E:/Temp/18_11_50_9710_01.trf":shakiness=5:accuracy=15:stepsize=6:mincontrast=0.3
-f null NUL
}}}
ffmpeg complains about:
{{{

this. Problem is that instead of:
{{{
E:/Temp/18_11_50_9710_01.trf
}}}
being passed to the filter as value for 'result' only 'E' is passed. :/
Adding backslashes and additional double quotes doesn't seem to help.
-> Does anyone know how the command line should look such that it is
properly escaped and handled by ffmpeg?

So either I'm simply don't know how to escape this properly (would be nice
if someone could tell me) or this is a bug. (Sample problem also happen
when using 'input' instead of 'result'.)
Thanks for looking into this. :)
