Comment:
(In [8623]) Fixes #1041, by applying patch.
This changes the default video buffer allocator from "new" to av_malloc.
"new" usually has an alignment equal to the largest non-SIMD register,
while av_malloc has a 16 byte alignment, which is generally better. If
someone needs a greater alignment, videobuffers allows the VideoOutput
class to allocate data itself. See VideoOutputXv for an example.
