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.
