abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
|
||||
|
||||
Typical reasons for an error here include:
|
||||
* The persistent store is not accessible;
|
||||
* The schema for the persistent store is incompatible with current managed object model.
|
||||
Check the error message to determine what the actual problem was.
|
||||
|
||||
|
||||
If the persistent store is not accessible, there is typically something wrong with the file path. Often, a file URL is pointing into the application's resources directory instead of a writeable directory.
|
||||
|
||||
If you encounter schema incompatibility errors during development, you can reduce their frequency by:
|
||||
* Simply deleting the existing store:
|
||||
[[NSFileManager defaultManager] removeItemAtURL:storeURL error:nil]
|
||||
|
||||
* Performing automatic lightweight migration by passing the following dictionary as the options parameter:
|
||||
@{NSMigratePersistentStoresAutomaticallyOption:@YES, NSInferMappingModelAutomaticallyOption:@YES}
|
||||
|
||||
Lightweight migration will only work for a limited set of schema changes; consult "Core Data Model Versioning and Data Migration Programming Guide" for details.

|

*
|
||||
* Libavresample (lavr) is a library that handles audio resampling, sample
|
||||
* format conversion and mixing.
|
||||
*
|
||||
* Interaction with lavr is done through AVAudioResampleContext, which is
|
||||
* allocated with avresample_alloc_context(). It is opaque, so all parameters
|
||||
* must be set with the @ref avoptions API.
|
||||
*
|
||||
* For example the following code will setup conversion from planar float sample
|
||||
* format to interleaved signed 16-bit integer, downsampling from 48kHz to
|
||||
* 44.1kHz and downmixing from 5.1 channels to stereo (using the default mixing
|
||||
* matrix):
|
||||
* @code
|
||||
* AVAudioResampleContext *avr = avresample_alloc_context();
|
||||
* av_opt_set_int(avr, "in_channel_layout", AV_CH_LAYOUT_5POINT1, 0);
|
||||
* av_opt_set_int(avr, "out_channel_layout", AV_CH_LAYOUT_STEREO, 0);
|
||||
* av_opt_set_int(avr, "in_sample_rate", 48000, 0);
|
||||
* av_opt_set_int(avr, "out_sample_rate", 44100, 0);
|
||||
* av_opt_set_int(avr, "in_sample_fmt", AV_SAMPLE_FMT_FLTP, 0);
|
||||
* av_opt_set_int(avr, "out_sample_fmt", AV_SAMPLE_FMT_S16, 0);
|
||||
* @endcode
|
||||
*
|
||||
* Once the context is initialized, it must be opened with avresample_open(). If
|
||||
* you need to change the conversion parameters, you must close the context with
|
||||
* avresample_close(), change the parameters as described above, then reopen it
|
||||
* again.
|
||||
*
|
||||
* The conversion itself is done by repeatedly calling avresample_convert().
|
||||
* Note that the samples may get buffered in two places in lavr. The first one
|
||||
* is the output FIFO, where the samples end up if the output buffer is not
|
||||
* large enough. The data stored in there may be retrieved at any time with
|
||||
* avresample_read(). The second place is the resampling delay buffer,
|
||||
* applicable only when resampling is done. The samples in it require more input
|
||||
* before they can be processed. Their current amount is returned by
|
||||
* avresample_get_delay(). At the end of conversion the resampling buffer can be
|
||||
* flushed by calling avresample_convert() with NULL input.
|
||||
*
|
||||
* The following code demonstrates the conversion loop assuming the parameters
|
||||
* from above and caller-defined functions get_input() and handle_output():
|
||||
* @code
|
||||
* uint8_t **input;
|
||||
* int in_linesize, in_samples;
|
||||
*
|
||||
* while (get_input(&input, &in_linesize, &in_samples)) {
|
||||
* uint8_t *output
|
||||
* int out_linesize;
|
||||
* int out_samples = avresample_available(avr) +
|
||||
* av_rescale_rnd(avresample_get_delay(avr) +
|
||||
* in_samples, 44100, 48000, AV_ROUND_UP);
|
||||
* av_samples_alloc(&output, &out_linesize, 2, out_samples,
|
||||
* AV_SAMPLE_FMT_S16, 0);
|
||||
* out_samples = avresample_convert(avr, &output, out_linesize, out_samples,
|
||||
* input, in_linesize, in_samples);
|
||||
* handle_output(output, out_linesize, out_samples);
|
||||
* av_freep(&output);
|
||||
* }
|
||||
* @endcode
|
||||
*
|
||||
* When the conversion is finished and the FIFOs are flushed if required, the
|
||||
* conversion context and everything associated with it must be freed with
|
||||
* avresample_free().

|
||||
*
|
||||
* @section ffmpeg_versioning Versioning and compatibility
|
||||
*
|
||||
* Each of the FFmpeg libraries contains a version.h header, which defines a
|
||||
* major, minor and micro version number with the
|
||||
* <em>LIBRARYNAME_VERSION_{MAJOR,MINOR,MICRO}</em> macros. The major version
|
||||
* number is incremented with backward incompatible changes - e.g. removing
|
||||
* parts of the public API, reordering public struct members, etc. The minor
|
||||
* version number is incremented for backward compatible API changes or major
|
||||
* new features - e.g. adding a new public function or a new decoder. The micro
|
||||
* version number is incremented for smaller changes that a calling program
|
||||
* might still want to check for - e.g. changing behavior in a previously
|
||||
* unspecified situation.
|
||||
*
|
||||
* FFmpeg guarantees backward API and ABI compatibility for each library as long
|
||||
* as its major version number is unchanged. This means that no public symbols
|
||||
* will be removed or renamed. Types and names of the public struct members and
|
||||
* values of public macros and enums will remain the same (unless they were
|
||||
* explicitly declared as not part of the public API). Documented behavior will
|
||||
* not change.
|
||||
*
|
||||
* In other words, any correct program that works with a given FFmpeg snapshot
|
||||
* should work just as well without any changes with any later snapshot with the
|
||||
* same major versions. This applies to both rebuilding the program against new
|
||||
* FFmpeg versions or to replacing the dynamic FFmpeg libraries that a program
|
||||
* links against.
|
||||
*
|
||||
* However, new public symbols may be added and new members may be appended to
|
||||
* public structs whose size is not part of public ABI (most public structs in
|
||||
* FFmpeg). New macros and enum values may be added. Behavior in undocumented
|
||||
* situations may change slightly (and be documented). All those are accompanied
|
||||
* by an entry in doc/APIchanges and incrementing either the minor or micro
|
||||
* version number.

|

* Buffer to print data progressively
|

*
|
||||
* The string buffer grows as necessary and is always 0-terminated.
|
||||
* The content of the string is never accessed, and thus is
|
||||
* encoding-agnostic and can even hold binary data.
|
||||
*
|
||||
* Small buffers are kept in the structure itself, and thus require no
|
||||
* memory allocation at all (unless the contents of the buffer is needed
|
||||
* after the structure goes out of scope). This is almost as lightweight as
|
||||
* declaring a local "char buf[512]".
|
||||
*
|
||||
* The length of the string can go beyond the allocated size: the buffer is
|
||||
* then truncated, but the functions still keep account of the actual total
|
||||
* length.
|
||||
*
|
||||
* In other words, buf->len can be greater than buf->size and records the
|
||||
* total length of what would have been to the buffer if there had been
|
||||
* enough memory.
|
||||
*
|
||||
* Append operations do not need to be tested for failure: if a memory
|
||||
* allocation fails, data stop being appended to the buffer, but the length
|
||||
* is still updated. This situation can be tested with
|
||||
* av_bprint_is_complete().
|
||||
*
|
||||
* The size_max field determines several possible behaviours:
|
||||
*
|
||||
* size_max = -1 (= UINT_MAX) or any large value will let the buffer be
|
||||
* reallocated as necessary, with an amortized linear cost.
|
||||
*
|
||||
* size_max = 0 prevents writing anything to the buffer: only the total
|
||||
* length is computed. The write operations can then possibly be repeated in
|
||||
* a buffer with exactly the necessary size
|
||||
* (using size_init = size_max = len + 1).
|
||||
*
|
||||
* size_max = 1 is automatically replaced by the exact size available in the
|
||||
* structure itself, thus ensuring no dynamic memory allocation. The
|
||||
* internal buffer is large enough to hold a reasonable paragraph of text,
|
||||
* such as the current paragraph.

|

* AVBuffer is an API for reference-counted data buffers.
|
||||
*
|
||||
* There are two core objects in this API -- AVBuffer and AVBufferRef. AVBuffer
|
||||
* represents the data buffer itself; it is opaque and not meant to be accessed
|
||||
* by the caller directly, but only through AVBufferRef. However, the caller may
|
||||
* e.g. compare two AVBuffer pointers to check whether two different references
|
||||
* are describing the same data buffer. AVBufferRef represents a single
|
||||
* reference to an AVBuffer and it is the object that may be manipulated by the
|
||||
* caller directly.
|
||||
*
|
||||
* There are two functions provided for creating a new AVBuffer with a single
|
||||
* reference -- av_buffer_alloc() to just allocate a new buffer, and
|
||||
* av_buffer_create() to wrap an existing array in an AVBuffer. From an existing
|
||||
* reference, additional references may be created with av_buffer_ref().
|
||||
* Use av_buffer_unref() to free a reference (this will automatically free the
|
||||
* data once all the references are freed).
|
||||
*
|
||||
* The convention throughout this API and the rest of FFmpeg is such that the
|
||||
* buffer is considered writable if there exists only one reference to it (and
|
||||
* it has not been marked as read-only). The av_buffer_is_writable() function is
|
||||
* provided to check whether this is true and av_buffer_make_writable() will
|
||||
* automatically create a new writable buffer when necessary.
|
||||
* Of course nothing prevents the calling code from violating this convention,
|
||||
* however that is safe only when all the existing references are under its
|
||||
* control.
|
||||
*
|
||||
* @note Referencing and unreferencing the buffers is thread-safe and thus
|
||||
* may be done from multiple threads simultaneously without any need for
|
||||
* additional locking.
|
||||
*
|
||||
* @note Two different references to the same buffer can point to different
|
||||

* AVBufferPool is an API for a lock-free thread-safe pool of AVBuffers.
|

|

* Frequently allocating and freeing large buffers may be slow. AVBufferPool is
|
||||
* meant to solve this in cases when the caller needs a set of buffers of the
|
||||
* same size (the most obvious use case being buffers for raw video or audio
|
||||
* frames).
|
||||
*
|
||||
* At the beginning, the user must call av_buffer_pool_init() to create the
|
||||
* buffer pool. Then whenever a buffer is needed, call av_buffer_pool_get() to
|
||||
* get a reference to a new buffer, similar to av_buffer_alloc(). This new
|
||||
* reference works in all aspects the same way as the one created by
|
||||
* av_buffer_alloc(). However, when the last reference to this buffer is
|
||||
* unreferenced, it is returned to the pool instead of being freed and will be
|
||||
* reused for subsequent av_buffer_pool_get() calls.
|
||||
*
|
||||
* When the caller is done with the pool and no longer needs to allocate any new
|
||||
* buffers, av_buffer_pool_uninit() must be called to mark the pool as freeable.
|
||||
* Once all the buffers are released, it will automatically be freed.
|
||||
*
|
||||
* Allocating and releasing buffers with this API is thread-safe as long as
|
||||
* either the default alloc callback is used, or the user-supplied one is
|
||||
* thread-safe.
