HI all, I am using NSTask to wrap ffmpeg, the video conversion utility.
I am able to invoke ffmpeg alright, but it’s unclear how the argument list should be passed through NSTask. I tried making my various arguments into one big string, but ffmeg doesn’t parse it, instead writing an error. Here’s my code: NSString* execPath = [[[self class] ffMPEGURL] path]; NSString* argString = [NSString stringWithFormat:@"-i \"%@\" -c copy %@", [url absoluteString], [self.outputFileURL absoluteString]]; self.ffMPEGTask = [NSTask launchedTaskWithLaunchPath:execPath arguments:@[argString]]; What the argument string should look like is: -i <source url> -c copy <dest file> ffmpeg responds: Unrecognized option 'i "http://<the stream url>" -c copy file:///<destination file>'. Error splitting the argument list: Option not found Obviously I need to pass the arguments differently, but it’s not clear what I need to do. —Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
