While I’m working on some longer posts, I thought I’d share a quick snippet I came up with this weekend as I was backing up a number of old DVDs of family movies.
FFMPeg has the awesome ability to join a number of video files together for you, but the syntax can be kind of strange. Once I learned the syntax, I sought to make sure I never had to do it again, and created this cmdlet.
Usage notes
In this basic version, it will join every file in a directory, giving you Output.mkv. Be sure your files in the directory are sequentially ordered as well, to control their position.
Ensure that FFMpeg’s binaries are available in your Path variable as well.
Later on, I may add the ability to provide which specific files you want to join, if desired 🙂
Enjoy 🙂

| $cmdScript += "ffmpeg -i `"$($item.Name)`" -f mpegts -c copy file-0$i.mpeg.ts`n" | |
| $fileArray.Add("file-0$i.mpeg.ts") | |
| } | |
| $cmdScript+="ffmpeg -isync -i `"concat:$($fileArray -join '|')`" -f matroska -c copy output.mkv" | |
| Invoke-Expression $cmdScript | |
