* swresample/resample: Limit filter lengthMichael Niedermayer2014-04-081-0/+5
| | | | | | | | | Related to CID1197063 The limit choosen is arbitrary and much larger than what makes sense. It avoids the need for checking arithmetic operations with the length for overflow Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | pshuf+paddd is slightly faster than phaddd. The real gain is in pre-ssse3 processors like AMD K8 and K10, which get a big boost in performance compared to the mmxext version Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | These are not supported by all compilers (gcc 2.95 but also older SPARC compilers, see gcc bug #33304 for example), and there is no real need for them. One use of this feature remains in libavdevice/v4l2.c which can't be replaced quite as easily. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* lavu,lavc,lswr: do not hardcode AV_SAMPLE_FMT_NB value when setting sample ↵Stefano Sabatini2013-12-261-6/+6
| | | | | | | | | | | | format max value The constant may change in libavutil but the library may be compiled against an older version, thus rejecting a value which is otherwise supported by the new libavutil. INT_MAX is used here to denote the max allowed value for a sample format. The opt-test code is changed to provide a valid reference example.
