Passing arguments to Powershells Call Operatore - I can't get it to work
2 janvier 2020, par morgola22For some reason I cannot get even the most simple Ffmpeg case to work :
$pathToFfmpeg = "PathToFfmpeg\ffmpeg.exe"
$video = "PathToVideoFile\video.mp4"
$param = "--i $video", "output.avi"
$execute = &$pathToFfmpeg $paramThis should result in the most basic Ffmpeg usage according to Ffmpeg website :
ffmpeg -i input.mp4 output.avi
.
However all I receive is :ffmpeg.exe : ffmpeg version git-2020-01-01-7b58702 Copyright (c) 2000-2020 the FFmpeg developers
At line:4 char:12

Error splitting the argument list: Option not foundSo it seems I am doing something wrong. Anybody knows how I get this to work ? I have tried different methods to create the params array and checked with EchoArgs.exe, but no avail. I am out of ideas. It looks like Ffmpeg does not recognise what Powershell is passing to it.

Cutting out a part of a video in ffmpeg creates a corrupted output file
30 octobre 2020, par lagmoellertimI currently have a problem with ffmpeg. I'm trying to cut out a part of a video (e.g. from 00:10:00 to 00:10:30).


I use this command
ffmpeg -ss 600 -to 630 -i not_working.mp4 not_working_part.mp4
.

I tried reencoding the video, but it is still corrupted (only first few frames working, video is multiple hours long but jumps to end if you try to skip).


I use the
-ss
and the-to
parameter before the-i
parameter because it is much faster I want to cut out a part that is e.g. right at the end of the video. Moving the-i
parameter infront of the other args solves the problem, but the performance is really bad for cutouts late in the video. For many other of my videos, both methods work without a problem.

Here is some metadata about the video from ffmpeg :
