Andreas Cadhalpun	9637c2531f	sonic: make sure num_taps * channels is not larger than frame_size If that is the case, the loop setting predictor_state in sonic_decode_frame causes out of bounds reads of int_samples, which has only frame_size number of elements.

Michael Niedermayer	6026a5ad4f	sonic: Switch to rangecoder significantly improves compression rate This also bumps version to 2 and drops support for version 0/1 If someone used version 0/1 despite their experimental status then support for these can and should be added back Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
