OSStatus error 1718449215

Question

I have created an iPhone application to record our voice. When I try to record, I am getting error message in following statement.

recorder = [[ AVAudioRecorder alloc] initWithURL:url settings:recordSetting error:&err];

Error Domain=NSOSStatusErrorDomain Code=1718449215 "Operation could not be completed. (OSStatus error 1718449215.)"

If I tried to record in .caf file, it is working fine. If I tried with .m4a, I am getting this error message.

Please help me to resolve it.

Thanks.

The question is out of date, but since I came here through Google I'd share this reference : osstatus.com allows you to look up the error codes – Heathcote

@Heathcote It may be old, but it's not out of date. I had the same error in 2017! – Florrieflorry

Same error occurring in my case too. @Heathcote – Lambart

Answer 1

1718449215 is the decimal representation of the four character code for the kAudioFormatUnsupportedDataFormatError error.

In general you can use something like this to get more information from the errors you receive:

NSError *error = [NSError errorWithDomain:NSOSStatusErrorDomain
                          code:my_error_code
                          userInfo:nil];
NSLog(@"Error: %@", [error description]);

.m4a is a file format, not a codec. The codec you are recording in is determined by AVFormatIDKey. – Craniometry

Answer 2

In case this helps others: I just had the same error, and it was caused by trying to create/use audio files in the wrong format. I had preset the recording to create a .caf file, but instead, called the file xxx.wav.

I had this same error when I had AVFormatIDKey set to kAudioFormatLinearPCM (wav format) but had forgotten to change the file extension on the destination file from .m4a to .wav. – Silverstein

Hi what extension should I have for kAudioFormatAMR? Thanks! – Berni

Answer 3

OSStatus error codes are pain, they are often too general to help. Did you try to decode the four-char error code? Sometimes that helps (other times you just get garbage). Create and show us a minimal code example that exhibits the problem. In this case I bet that the four-char code is fmt?. Google for the numeric code and you should be wiser.

Answer 4

I also faced this issue when I converted file type to .mp3 while previously I was using .caf format for recording sound with AVAudioRecorder. I again converted file type to.caf format & it works. You may use following formats

AAC, PCM, IMA4, ULAW, ILBC

Thanks for the formats, which file extensions are allowed by iOS? for examploe, what is the file extension for an ULAW formatted file? – Indigested

Answer 5

"NSDictionary" if it is empty, the default is high quality, if you set, this value will be very low, you can try to cancel these parameters:

setting[AVFormatIDKey] = @(kAudioFormatAppleIMA4);
setting[AVSampleRateKey] = @(600.0);
setting[AVNumberOfChannelsKey] = @(1);
setting[AVLinearPCMBitDepthKey] = @(8);

Answer 6

My favourite tool for deciphering OSStatus codes is https://osstatus.com

OSStatus error 1718449215 is kAudioConverterErr_FormatNotSupported, which may mean:

• The format you're trying to export to is not supported (double check the file extension of your output file URL).

• There's an issue with the recordSettings. One thing to look out for is that the value of the AVFormatIDKey matches the file extension of the output file URL.

Answer 7

If you're in c or cpp code you can do this.

char code[4];
*((SInt32*)&code[0]) = error;

Answer 8

UInt32 code = CFSwapInt32HostToBig(error);
NSLog(@"%4.4s"(char *)&code);
