However, unless specifically defined in a requirements.txt or pipfile.lock, package managers will not deal with transitive dependencies (ie., dependencies of dependencies). (Also note that there is no shell to split the arguments at spaces, so ffmpeg will receive the arguments in exactly the form specified by the array.All Python package management solutions provide the basic function of uninstalling packages, including pip, pipenv and the ActiveState Platform. Note that since the arguments are passed directly, there is no intervening shell to interpret the quotation marks, so leave them out. The variant that bypasses the shell and interacts directly with the executable at a given path is this: let ffmpeg = ExternalProcess(at: URL(fileURLWithPath: "/usr/local/bin/ffmpeg")) However, based on the “command not found” error you got, it does not look like ffmpeg is registered in $PATH in whatever environment you are in. this was what I meant: let output = try ( $ ffmpeg -nostdin -i '.' -c:v copy -c:a copy '.' mp4 extension instead) and run in Terminal using swift ~/path/to/FfmpegCommand.swift.Īssuming the command you would use in terminal is. To test, replace the placeholders in the script with the path to the video and the path to it's output (usually, I just specify the same path as the input, but with an. Here is a simplified version of my script that still encounters the issue: Here is the video I'm testing the script with: Dropbox - File Deleted Any insight on this would be much appreciated.įfmpeg is installed on my system through Homebrew: brew tap slhck/ffmpegīrew install slhck/ffmpeg/ffmpeg -with-aom -with-fdk-aac I'm not entirely sure how to fix this, to get the full command to run and then exit once finished. I need to run ffmpeg via Process and in doing so, I've noticed that once it starts running it never does anything (as it never even creates the output file) and never stops running. I'm having some issues with a script I'm trying to write to automate some of my ffmpeg video commands.
