I'm trying to write a piece of code that would "modernize" a video file. This is the code :

NSOpenPanel *openPanel = [[NSOpenPanel alloc] init];
[openPanel setCanChooseFiles:NO];
[openPanel setCanChooseDirectories:YES];

if([openPanel runModal] == NSCancelButton)
     return;
NSMutableString *destination = [[[openPanel URL] absoluteString] mutableCopy];
[destination appendString:@"/"];
[destination appendString:[self fileName:[url absoluteString] withExtention:NO]];
[destination appendString:@".m4v"];

QTMovieModernizer *modernizer = [[QTMovieModernizer alloc] initWithSourceURL:url destinationURL:[NSURL URLWithString:destination]];

[modernizer modernizeWithCompletionHandler:^{NSLog(@"Modernization complete to file %@ - error : %@",[modernizer destinationURL],[modernizer error]);}];

The problem is that I get an NSInvalidArgumentException. I've checked the source and destination url carefully and they seem to be ok. The error seems to happen at the initialization the QTMovieModernizer instance. What can be going wrong here?

Error details :

EDIT :

I found out that -fileName:withExtension: returns a string by replacing %20 by spaces. After handling this, the exception at the initsilizing is gone but instead, I have the following error when converting the file :

  <<<< QTMovieModernizer >>>> FigFormatUtilsCreateFormatReader: Error -12848 from       FigFormatReaderCreateForStream
  <<<< QTMovieModernizer >>>> formatReaderForSourceURL: Error in FormatReaderForSourceURL: -12848

  • What's the full error message? – rmaddy May 14 '14 at 17:55
  • @rmaddy that's the full error message just `An uncaught exception was raised` before this. – user26830 May 14 '14 at 18:07
  • if you can print out the full source & destination URL's, what do they look like? – Michael Dautermann May 14 '14 at 18:10
  • @MichaelDautermann the variable are here : `destination __NSCFString * @"file:///Users/Moray/Desktop//S1%20E01%20-%20My%20First%20Day.m4v" 0x0000608000a75240`, `url NSURL * @"file:///Users/Moray/Movies/Scrubs/Season%201/S1%20E01%20-%20My%20First%20Day.avi" 0x000060000067a340` – user26830 May 14 '14 at 18:15
