Andreas Cadhalpun	75fd5ce4c1	imc: use correct position for flcoeffs2 calculation 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.

Christophe Gisquet	4728cdd880	imc: reject files with unfathomable sampling rates With huge sampling rates, the table derivation method does not converge fast enough. While fixing it using e.g. Newton-Rhapson-like methods (the curve is nicely convex) is possible, it is much simpler to reject these cases. The value of 96000 was arbitrarily chosen as a realistic value, though 1000000 would still work and converge. Fixes ticket #3868.

Kostya Shishkov	cac4760bf4	iac: generate codec tables as they are supposed to be 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.

Mans Rullgard	a1e98f198e	get_bits: remove A32 variant 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>	13 years ago

Justin Ruggles	a4998e448f	imc: return error codes instead of 0 for error conditions. 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.	13 years ago
