* imc: Use correct position for flcoeffs2 calculationAndreas Cadhalpun2015-07-101-1/+1
| | | | | | | | | | | | flcoeffs2[pos] should be the log2 of flcoeffs1[pos]. flcoeffs1[0] can be 0 here, thus flcoeffs2[pos] gets set to -inf, causing problems further down. This seems to have been copied from imc_decode_level_coefficients in commit 4eb4bb3 without updating the position.

* floatdsp: move butterflies_float from dsputil to avfloatdsp.Ronald S. Bultje2013-01-221-2/+5
| | | | | This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.

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

* iac: generate codec tables as they are supposed to beKostya Shishkov2012-06-091-6/+62
| | | | | | | | | Unlike its predecessor, Indeo Audio codec generates tables depending on sampling rate. Previously decoder used pre-generated tables for 22050 Hz which obviously doesn't work with other frequencies. Many thanks to Maxim Poliakovsky for providing all needed information for this.

* get_bits: remove A32 variantMans Rullgard2011-12-161-1/+0
| | | | | | | | | | | | | | | | | The A32 bitstream reader variant is only used on ARMv5 and for Prores due to the larger bit cache this decoder requires. In benchmarks on ARMv5 (Marvell Sheeva) with gcc 4.6, the only statistically significant difference between ALT and A32 is a 4% advantage for ALT in FLAC decoding. There is thus no (longer) any reason to keep the A32 reader from this point of view. This patch adds an option to the ALT reader increasing the bit cache to 32 bits as required by the Prores decoder. Benchmarking shows no significant change in speed on Intel i7. Again, the A32 reader fails to justify its existence. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Add avcodec_decode_audio4().Justin Ruggles2011-12-021-10/+19
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
* imc: return error codes instead of 0 for error conditions.Justin Ruggles2011-11-021-2/+2
| | | | | This fixes a bug where the whole buffer was returned as decoded audio due to *data_size not being set to zero and the return value being >= 0.
* imc: return meaningful error codes instead of -1Justin Ruggles2011-11-021-9/+10

| | | | | | | These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by rdft. Signed-off-by: Mans Rullgard <mans@mansr.com>
* fft: remove inline wrappers for function pointersMans Rullgard2011-03-191-2/+2
