Lots of ways to expand this.It's taken me a month of Sundays (Mondays, Tuesday and Wednesdays) but finally got a FULL set of fully feature enabled 4.0.2 ffmpeg and tools (ffplay, ffprobe etc.) built for Windows 32/64bit from the latest (4.0.2) source.
You can make the script constantly run on your machine, monitor a folder every so often, etc… and have it automatically detect two files of the same name (sans extension) and merge them. You can easily automate this if you have a lot of work. With ffmpeg the output file is just the size of the two combined. I tried it first with the built in video creator for Windows 10, it’s slow and it took a 400MB video file and 40MB audio file and created a 1.4GB combined file… wow. The best part about this is that it is FAST. This works especially well for YouTube videos or others where you have to download them as separate files. FileName Start-Process -FilePath $ffmpeg -ArgumentList "-i ""$vidPath"" -i ""$audioPath"" -c:v copy -c:a copy ""$outputFilePath""" Read-Host "Press any key to exit" ShowDialog() | Out-Null $audioPath = $OpenFileDialog. filter = "Videos (*.m4a)| *.m4a" $OpenFileDialog. FileName If (! $outputFilename ) $outputFilePath = "C:\Users\me\Downloads\$outputFilename" $OpenFileDialog. ShowDialog() | Out-Null $vidPath = $OpenFileDialog. filter = "Videos (*.mp4)| *.mp4" $OpenFileDialog. initialdirectory = "C:\Users\me\Downloads\" $OpenFileDialog. Thanks to this page for the ffmpeg command line: Īdd-Type -AssemblyName | Out-Null $outputFilename = Read-Host "Enter Output Filename" $ffmpeg = "C:\ffmpeg-4.0.2-win64-static\bin\ffmpeg.exe" $OpenFileDialog = New-Object $OpenFileDialog. By default it just adds that to the name of the video file, for the combined output file. Also, because the video alone is an mp4 and the output will be an mp4, I randomly chose to insert a “2-” in the front of the filename if I don’t type one in at that starting prompt. If you are going to work with files other than mp4 and m4a, then update (or just remove the line) with the filter. I wrote it so the output just goes to the same directory where the files are but you can easily change that. Be sure to update the path to the ffmpeg executable to wherever you put it and whatever starting directory you want for the files. I threw it in some Powershell to make it easy to use.Ī graphical file selection for both video and audio files.
And it turns out it is, with a very simple one liner. I then had the idea to find out if it was possible with FFMPEG (a lot of software uses it anyway). I had been searching for an easy solution to combine a video file with it’s separate audio file but simply Googling that gives a bunch of results that require downloading software from questionable places.
