Description

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:

[vidstabdetect @ 0000020653ce6800] [Eval @ 000000fec75fdcd0] Undefined constant or missing '(' in '/Temp/18_11_50_9710_01.trf'

[Parsed_vidstabdetect_0 @ 0000020653cb2d00]         result = E

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?

'm using:

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. :)

You need to escape the colon, and use single quotes.

'E\:/Temp/18_11_50_9710_01.trf'
