There is a theoretical possibility to pass a very long string to ff_parse,
which could crash if allocated from the stack. This allows the allocation
to be checked properly.

pred_order can never exceed 32, so always allocating that amount is safe
and not very wasteful.

When a frame is allocated using libschroedinger routines, the frame data size
does not match the actual frame size if the width is not a multiple of 16. So
we cannot do a straightforward memcpy of the frame returned by libschroedinger
into the FFmpeg picture as the stride differs from the width.
Fix this bug by allocating for the libschroedinger frame with the dimensions
in AVCodecContext within libavcodec and passing the frame to libschroedinger.

convolution in the upcoming AMR-NB floating point decoder. The function scales
and adds a vector, that is lagged by some offset, to another vector with the
same number of elements.

The RV10/RV20 encoders depend on the H.263 encoder.
