* arm: fix use of uninitialised value in ff_fft_fixed_init_arm()Mans Rullgard2012-12-07
| | | | | | | | | When initialising an FFTContext for a plain FFT, mdct_bits is not set and can contain a garbage value. Since nbits is always valid and for MDCT operation is mdct_bits - 2 checking this instead avoids using an uninitialised value while having the same effect.

* ARM: allow runtime masking of CPU featuresMans Rullgard2012-04-22
| | | | | | | This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>
