37390d5cca apedec: allow the user to set the maximum number of output samples per call
It makes sense in some cases to split up the output packet to save on memory
usage (ape frames can be very large), but the current/default size is
arbitrary. Allowing the user to configure this gives more flexibility and
requires minimal additional code.

0927154d37 apedec: use FFALIGN macro for internal data buffer size 2011-10-28 11:47:28 -04:00

5b8009f4c8 apedec: do not keep incrementing the input data pointer past the end of the
buffer during entropy decoding.

The pointer address could overflow, which would likely segfault. Instead set
the context error flag to indicate that the decoder tried to read past the
end of the packet data.

fd244ae3a0 apedec: use unsigned int for offset
avoids implementation-defined unsigned-to-signed conversion and simplifies
the bounds checking.

89ec474a43 apedec: remove pointless increment of 'buf'
The variable is not used anymore at that point.

2cab578489 apedec: use unsigned int for 'nblocks' and make sure that it's within int range 2011-10-28 11:47:27 -04:00

b7e5145759 apedec: do not set s->samples until after validation.
This prevents errors and/or invalid writes in the next decode call due to
s->samples still being negative.
