Ffmpeg-kit not detecting my vidoe file (iOS Development, Swift) but the actual application does
I have a video file in the project folder that is detected by the app as VideoPlayer(player: AVPlayer(url: url)) does make use of it and play it on the iPhone screen, I have the video path of simply videoURL = Bundle.main.url(forResource: "Earth_Zoom_In", withExtension: "mov")
Now, a kind gentleman gave me this code just yesterday:
func syncCommand() {
guard let session = FFmpegKit.execute("-i Earth_Zoom_In.mov -c:v file1.mp4") else {
print("!! Failed to create session")
return
}
let returnCode = session.getReturnCode()
if ReturnCode.isSuccess(returnCode) {
print("COOOOL");
} else if ReturnCode.isCancel(returnCode) {
print("CANCELED???? WHAT?????");
} else {
print("Command failed with state \(FFmpegKitConfig.sessionState(toString: session.getState()) ?? "Unknown") and rc \(returnCode?.description ?? "Unknown").\(session.getFailStackTrace() ?? "Unknown")")
}
}
But Ffmpeg seems to not find the file as when the function is executed I get ERROR: Earth_Zoom_In.mov: No such file or directory
But it is on the directory...
Can anyone help me with that? 🥹🥹🥹 please.
I have tried:
guard let session = FFmpegKit.execute("-i \(url) -c:v file1.mp4") else {
inside of syncCommand(url: URL?) and change the code in my init
to init() {
videoURL = Bundle.main.url(forResource: "Earth_Zoom_In", withExtension: "mov")
syncCommand(url: videoURL);
}
so video URL is on scope... but again, the same error, just with a complete path this time...

Solution
Sooo, welcome to the wonderful world of "file handling in Swift/iOS"
First, you should probably take a look at:
- iOS storage best practices
FileManager- Working with files and folders in Swift
- Working with Files on iOS with Swift
... and, you know what, you could probably google for more 😉
First Bundle.main.url is going to give a URL, which is helpful, but you need a String. It would start by using URL#path and test to see if that works, otherwise URL#description will be what you want (sorry, I'm vague, been awhile since I needed to this)
Next, you need somewhere to output the file to. iOS (and even MacOS) are sandboxed, so you must "ask" the system where you can write things to do. In this, I might consider using the "cache" directory, a few reasons, but mostly it won't expose the file to the user (you could store it in the "documents" directory if you wanted to)
So, all that might look something like...
guard let input = Bundle.main.url(forResource: "Earth_Zoom_In", withExtension: "mov") else { return }
guard let outputPath = FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask).first else { return }
let output = outputPath.appendingPathComponent("file1.mp4")
Then you can use them in your command something like...
FFmpegKit.execute("-i \(input.path) -c:v \(outputPath.path)")
Now, if this fails, you need to use FFmpegKit.execute("-i \(input) -c:v \(outputPath)") instead, which will produce a file:// based URL string
nb: Based on some, very old code, I was using URL#path
Notes
- File management on iOS is much more restrictive then on MacOS, you are only allowed to write within the sandboxed constraints of the App.
- If you wish to "share" the file, under iOS, the
.documentsdirectory is probably preferred. You could write directly to it, or do a move/copy operation later. - Under MacOS, you may not be allowed to write to certain locations without first having specified your intent in the app's "capability" and gotten permission from the user before hand
