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	291747581e	imc: make issue non-fatal The "faulty" samples actually sound fine when ignoring this issue. For ticket #3886, more samples are decoded. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

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.
