RELEASE NOTES - v0.12.0
=======================
Version 0.12.0 has breaking API changes including changes to the existing API and the removal of deprecated APIs.
Improved Client-Defined Memory Allocation
-----------------------------------------
The main change with this release is the addition of a more flexible way of implementing custom memory allocation routines. The
existing system of DRFLAC_MALLOC, DRFLAC_REALLOC and DRFLAC_FREE are still in place and will be used by default when no custom
allocation callbacks are specified.
To use the new system, you pass in a pointer to a drflac_allocation_callbacks object to drflac_open() and family, like this:
void* my_malloc(size_t sz, void* pUserData)
{
return malloc(sz);
}
void* my_realloc(void* p, size_t sz, void* pUserData)
{
return realloc(p, sz);
}
void my_free(void* p, void* pUserData)
{
free(p);
}
...
drflac_allocation_callbacks allocationCallbacks;
allocationCallbacks.pUserData = &myData;
allocationCallbacks.onMalloc = my_malloc;
allocationCallbacks.onRealloc = my_realloc;
allocationCallbacks.onFree = my_free;
drflac* pFlac = drflac_open_file("my_file.flac", &allocationCallbacks);
The advantage of this new system is that it allows you to specify user data which will be passed in to the allocation routines.
Passing in null for the allocation callbacks object will cause dr_flac to use defaults which is the same as DRFLAC_MALLOC,
DRFLAC_REALLOC and DRFLAC_FREE and the equivalent of how it worked in previous versions.
Every API that opens a drflac object now takes this extra parameter. These include the following:
drflac_open()
drflac_open_relaxed()
drflac_open_with_metadata()
drflac_open_with_metadata_relaxed()
drflac_open_file()
drflac_open_file_with_metadata()
drflac_open_memory()
drflac_open_memory_with_metadata()
drflac_open_and_read_pcm_frames_s32()
drflac_open_and_read_pcm_frames_s16()
drflac_open_and_read_pcm_frames_f32()
drflac_open_file_and_read_pcm_frames_s32()
drflac_open_file_and_read_pcm_frames_s16()
drflac_open_file_and_read_pcm_frames_f32()
drflac_open_memory_and_read_pcm_frames_s32()
drflac_open_memory_and_read_pcm_frames_s16()
drflac_open_memory_and_read_pcm_frames_f32()
Optimizations
-------------
Seeking performance has been greatly improved. A new binary search based seeking algorithm has been introduced which significantly
improves performance over the brute force method which was used when no seek table was present. Seek table based seeking also takes
advantage of the new binary search seeking system to further improve performance there as well. Note that this depends on CRC which
means it will be disabled when DR_FLAC_NO_CRC is used.
The SSE4.1 pipeline has been cleaned up and optimized. You should see some improvements with decoding speed of 24-bit files in
particular. 16-bit streams should also see some improvement.
drflac_read_pcm_frames_s16() has been optimized. Previously this sat on top of drflac_read_pcm_frames_s32() and performed it's s32
to s16 conversion in a second pass. This is now all done in a single pass. This includes SSE2 and ARM NEON optimized paths.
A minor optimization has been implemented for drflac_read_pcm_frames_s32(). This will now use an SSE2 optimized pipeline for stereo
channel reconstruction which is the last part of the decoding process.
The ARM build has seen a few improvements. The CLZ (count leading zeroes) and REV (byte swap) instructions are now used when
compiling with GCC and Clang which is achieved using inline assembly. The CLZ instruction requires ARM architecture version 5 at
compile time and the REV instruction requires ARM architecture version 6.
An ARM NEON optimized pipeline has been implemented. To enable this you'll need to add -mfpu=neon to the command line when compiling.
Removed APIs
------------
The following APIs were deprecated in version 0.11.0 and have been completely removed in version 0.12.0:
drflac_read_s32() -> drflac_read_pcm_frames_s32()
drflac_read_s16() -> drflac_read_pcm_frames_s16()
drflac_read_f32() -> drflac_read_pcm_frames_f32()
drflac_seek_to_sample() -> drflac_seek_to_pcm_frame()
drflac_open_and_decode_s32() -> drflac_open_and_read_pcm_frames_s32()
drflac_open_and_decode_s16() -> drflac_open_and_read_pcm_frames_s16()
drflac_open_and_decode_f32() -> drflac_open_and_read_pcm_frames_f32()
drflac_open_and_decode_file_s32() -> drflac_open_file_and_read_pcm_frames_s32()
drflac_open_and_decode_file_s16() -> drflac_open_file_and_read_pcm_frames_s16()
drflac_open_and_decode_file_f32() -> drflac_open_file_and_read_pcm_frames_f32()
drflac_open_and_decode_memory_s32() -> drflac_open_memory_and_read_pcm_frames_s32()
drflac_open_and_decode_memory_s16() -> drflac_open_memory_and_read_pcm_frames_s16()
drflac_open_and_decode_memory_f32() -> drflac_open_memroy_and_read_pcm_frames_f32()
Prior versions of dr_flac operated on a per-sample basis whereas now it operates on PCM frames. The removed APIs all relate
to the old per-sample APIs. You now need to use the "pcm_frame" versions.

Remarks
-------
The offset will never be negative. Whether or not it is relative to the beginning or current position is determined by the "origin" parameter which will be
either drflac_seek_origin_start or drflac_seek_origin_current.
Seeking relative to the start and the current position must always be supported. If seeking from the end of the stream is not supported, return DRFLAC_FALSE.
When seeking to a PCM frame using drflac_seek_to_pcm_frame(), dr_flac may call this with an offset beyond the end of the FLAC stream. This needs to be detected
and handled by returning DRFLAC_FALSE.

REVISION HISTORY
================
v0.13.0 - TBD
- API CHANGE: Seek origin enums have been renamed to match the naming convention used by other dr_libs libraries:
- drflac_seek_origin_start -> DRFLAC_SEEK_SET
- drflac_seek_origin_current -> DRFLAC_SEEK_CUR
- DRFLAC_SEEK_END (new)
- API CHANGE: A new seek origin has been added to allow seeking from the end of the file. If you implement your own `onSeek` callback, you should now detect and handle `DRFLAC_SEEK_END`. If seeking to the end is not supported, return `DRFLAC_FALSE`. If you only use `*_open_file()` or `*_open_memory()`, you need not change anything.
- API CHANGE: An `onTell` callback has been added to the following functions:
- drflac_open()
- drflac_open_relaxed()
- drflac_open_with_metadata()
- drflac_open_with_metadata_relaxed()
- drflac_open_and_read_pcm_frames_s32()
- drflac_open_and_read_pcm_frames_s16()
- drflac_open_and_read_pcm_frames_f32()
- Fix compilation for AIX OS.
v0.12.43 - 2024-12-17
- Fix a possible buffer overflow during decoding.
- Improve detection of ARM64EC
v0.12.42 - 2023-11-02
- Fix build for ARMv6-M.
- Fix a compilation warning with GCC.
