Hi all,
I am currently plagued with a most perplexing issue. I am trying to
export the raw data packets from MP3s that are stored in my device's
iTunes library. I have about roughly 1500 MP3s stored on my iPhone 4. I
am using an AVAssetReader and an AVAssetReaderTrackOutput to write the
raw audio samples. Unfortunately, after about 370 successful exports,
the call to create/init the AVAssetReader fails with the following
error: "The operation couldn't be completed. (AVFoundationErrorDomain error
-11800.)
The problem is, the AVFoundation framework seems unable to recover when
this error occurs. This means that all future attempts to export an MP3
(or an M4A file using an AVAssetExportSession) fail immediately with
error -11800.
Has anyone observed this behavior? I've tried many different
permutations of allocating/releasing the AVAssetReader. Instruments does
not report any memory leaks. Does anyone know of a way to "reset" the
AVFoundation framework once this error occurs?
Thanks very much,
Zach
