Michael Niedermayer	6a287b739f	Detect and prevent reading over the end of counts_*. We pass the error through a context variable as this is simpler and i think also faster, but the return value of functions could be used instead of course. The code also ensures as a side effect that the AC decoder state does not become invalid. This fixes all known crashes. And outputs nothing in case of an error instead of random noise.

Aurelien Jacobs	49c35f16fc	Fix compilation on powerpc. DECLARE_ALIGNED_8 is not defined at that point, but this code is powerpc only, so it's really equivalent to DECLARE_ALIGNED(16... Originally committed as revision 12313 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Justin Ruggles	d8870f120e	use scale factor instead of sum for downmix level adjustment. avoids division inside downmix loop. 7% faster 5.1-to-stereo downmixing. Originally committed as revision 12287 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Reimar Döffinger	7e14b8082d	Use cltd instead of cdq asm mnemonic, ICC and gcc support both, but SunStudio 12 only supports the former. Originally committed as revision 12275 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	499e4700ef	Stuffing bytes to not violate minimum legality rate. Note, this is a joke and not related to MPEG CBR. Originally committed as revision 12244 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	92ac614f85	Avoid a=b+c but rather use a+=b (gcc is too stupid to do this itself), code is exactly the same just uses different variables. Originally committed as revision 12235 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
