Express bitfields more simply.

Those decoders have been switched to float output and so do not use
fmtconvert anymore.
|

|
|
|

|

These are the only WMA bits shared with binkaudio. Splitting them off
reduces the binnkaudio dependency on general WMA code.

It will be useful in the upcoming transition to refcounted AVFrames.
|

|

Normal get_bits() already has overread protection.
|

|

Use planar for DCT codec, interleaved for RDFT codec.
|
|
|
|
| |
Eliminates the need for vector_fmul_scalar() in each frame.

Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

The existing functions defined in intfloat_readwrite.[ch] are
both slow and incorrect (infinities are not handled).
This introduces a new header with fast, inline conversion
functions using direct union punning assuming an IEEE-754
system, an assumption already made throughout the code.
The one use of Intel/Motorola extended 80-bit format is
replaced by simpler code sufficient under the present
constraints (positive normal values).
The old functions are marked deprecated and retained for
compatibility.

Deprecate avcodec_decode_audio3().
Implement audio support in avcodec_default_get_buffer().
Implement the new audio decoder API in all audio decoders.

This prevents truncating output due to an output buffer that is too small for
all blocks. There is no limit on the number of blocks in a packet.
|
|
|
|
|
| |
This fixes the requirement for the buffer size to be larger than the number of
samples actually decoded.
|
| |
|
|
|
|
| |
This stops decoding before overreads instead of after.
|
|
|
|
| |
It's more readable and less prone to breakage.

This is needed because not all players (e.g. MPlayer) are able to distinguish
two different Bink audio decoders when codec_tag is set.

This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.

This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

decode_init sets bands[0] == 2, so this loop always sets the band table
index (k) to zero.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

None of these symbols should be accessed directly, so declare them as

These macros are redundant. All uses are replaced with the generic
DECLARE_ALIGNED macro instead.
