if a movie finishes with an error, then I might get an error like:
Error Domain=MediaPlayerErrorDomain Code=-12847 "This movie format is
not supported."
The same description is used for different error codes - but I can't find the code definitions anywhere.
Are they available?
Here you go. https://developer.apple.com/library/mac/#documentation/AVFoundation/Reference/AVFoundation_ErrorConstants/Reference/reference.html
God help you if your code (like mine) was -11800 (AVErrorUnknown).

I'm attempting to write an AAC file from the output stream of an AUGraph, and on playback my file only plays a buzzing noise, and I get the error ExtAudioFileWriteAsync -50.
I'd like to know what it means so that I can search for and destroy the problem.
Thanks to any Core Audio ninjas that can hook a brother up.
In case anyone else has this problem, the -50 error is a kAudio_ParamError error, defined in CoreAudioTypes.h.
Therefore, one of the parameters being passed to ExtAudioFileWriteAsync must be faulty.
When I run my app, i get one error and i dont know how to fix it. Can someone help me?
Here is the error:
Command /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1

The causative problem is the error immediately preceding that one, the duplicate symbol error.
gcc-4.2 failed with exit code 1 Error Occurs due to some of your file or frame work are duplicated check it out which file is in you target link file or in your framework are repeated.
from your log message "didUpdate" may be repeated in your project look for that...
May be this is helpful to You.
From the error message, it seems like didUpdate is defined more than once in your code. Search for didUpdate on your workspace and make sure it's only being defined once.
Either you are redefining variable or you are probably importing a *.m file somewhere in your project.Try importing corresponding *.h file.
I'm searching some precise doc where I can associate an error number to its constant. Let's say, for example, I'm searching the constant of NSError.code = 102. How may I do to find it ? Searching the Web does not help. Searching the headers file is a headache.
How would you do this ?
you can find some of refrences here for NSError
http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSError_Class/Reference/Reference.html
you can found some of error detail here
http://www.lifeasbob.com/Code/ErrorCodes.aspx
The code should belong to the domain of NSError, check the documentation for the associated error domain and you should find the correct code. The domain is also a good hint of which headers to search if documentation is unavailable. Apple does list the Foundation Constants.
It's WebKitErrorDomain - WebKitErrorFrameLoadInterruptedByPolicyChange

I am trying to stream sensor data from the iRobot Create. I get tuple out of range errors when I try
bot.stream_sensors(somenumber) and bot.poll_sensors(somenumbers). Whenever I input bot.sensors, I just get an empty array {}. I have even tried sending bot.sensors while pushing in on the bump sensor, still getting an empty array. I am connected to the bot through the Serial port with a serial-to-usb converter on my side. The only code before trying to get the sensor data is
import openinterface
bot = openinterface.CreateBot(com_port="/dev/ttyUSB0", mode="full")
Does anyone have an idea of how to solve this issue? Everywhere else just uses stream_sensors(6) and it seems to work fine.
P.S. I posted a question similar to this topic not too long ago, but no one responded. Not trying to spam, but now I have a more clear question and what the apparent-problem is so I thought I would try again.
I downloaded openinterface.py from this site: which included some sample programs. I'd suggest you take a step back, try the sample code, try to find other, more sophisticated, sample code and play with that first before moving on to your real code. You may be missing a step somewhere.
I may be a bit late to answer this, but for reference purposes. Directly controlling the iRobot is simplified greatly by using
Pyrobot.
I recently ran into a problem that I couldn't find discussed anywhere on the internet - I was initializing an AVAudioPlayer to play an audio file, and getting the following error:
Error Domain=NSOSStatusErrorDomain Code=-50 "Operation could not be completed. (OSStatus error -50.)
As it turns out, I had made a mistake creating my NSURL to send to the audio player init method, resulting in the NSURL object being null. Stupid mistake, pretty easy to find when debugging, but I thought I'd list it here just in case someone else does the same thing.
“ OSStatus error -50” means paramErr, an old-style Mac error code indicating a bad parameter.
Regarding the comment from Brynjar:
The Apple NSURL Class Reference describing URLWithString states
To create NSURL objects for file system paths, use
fileURLWithPath:isDirectory: instead.
I have found that using URLWithString for file system paths generates the error reported by pix0r and therefore could be another explanation for error code = -50
Make sure your NSURL is valid, or you will get error code -50 "Operation could not be completed".
I'm adding my version of the issue and solution because I encountered the error with a print statement. I think it was related to string interpolation and or trying to forcibly print nsattributedstrings. I attempted to do the following.
print("THE ARRAY COUNT IS : \(unwrappedResults.count)\n\n\n
THE FULL ARRAY IS THE FIRST WHOLE RESULT IS: \(unwrappedResults)\n\n\n \ (unwrappedResults[0])\n
THE ATTRIBUTED FULL TEXT IS: \(unwrappedResults[0].attributedFullText)\n\n\n
THE ATTRIBUTED PRIMARY TEXT IS: \(unwrappedResults[0].attributedPrimaryText)\n\n\n
THE ATTRIBUTED SECONDARY TEXT IS: \(unwrappedResults[0].attributedSecondaryText)\n\n\n")
something about this was incorrect and no print would occur. I would receive the error following errors in my console.
boringssl_metrics_log_metric_block_invoke(131) Failed to log metrics
&
boringssl_metrics_log_metric_block_invoke(133) Error Domain=NSOSStatusErrorDomain Code=-50 "Unsupported xpc type"
UserInfo={NSDescription=Unsupported xpc type}
I fixed this issue by changing the way I unwrapped/the variables values. Fundamentally I think I was trying to print something using string interpolation that could not be printed and that is what caused this error.
