2015-04-29avresample: Reallocate the internal buffer to the correct sizeLuca Barbato
Fixes the corner case in which the internal buffer size is larger than input buffer provided and resizing it before moving the left over samples would make it write to now unallocated memory. Bug-Id: 825 CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

This simplifies the code, since we do not have to deal with a possibly negative source index anymore.

The correct "next" input sample is not the first sample of the resampling buffer, but the center sample of the filter_length-sized block at the beginning. CC:libav-stable@libav.org

2013-01-08lavr: typedef internal structs in internal.hJustin Ruggles
Simplifies header dependencies by not including all other internal headers in internal.h.
2012-12-17lavr: remove automatic context close/open for resampling compensationJustin Ruggles
It adds unnecessary complication for insignificant usability improvement. The user really should know if they'll need resampling compensation before opening the context. Note that only the documentation has changed. The current functionality will still work until the next major bump.

2012-11-28lavr: do not pass consumed samples as a parameter to ff_audio_resample()Justin Ruggles
Since the resampler handles buffering of unconsumed samples internally, the caller does not need this information.
