[FFmpeg-devel] [PATCH v2 3/4] lavfi/qsvvpp: provide a default framerate if needed

[Xiang, Haihao]

From: Haihao Xiang <haihao.xiang at intel.com>

VPP in the SDK requires the frame rate to be set to a valid value,
otherwise init will fail, so always set a default framerate when the
input link doesn't have a valid framerate.
