[FFmpeg-devel] [PATCH 2/2] lavfi/aresample: set buffer properties after copy.

[Nicolas George]

The aresample filter changes the format, layout and/or sample rate,
it can not copy them blindly from its input.

Fix trac ticket 1671 because af_volume uses the properties from the
buffer and not from the link.
