[FFmpeg-devel] [PATCH] lavfi/vf_vpp_qsv: set the default value of async_depth to 4

[FFmpeg-devel] [PATCH] lavfi/vf_vpp_qsv: set the default value of async_depth to 4

[Xiang, Haihao]

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

Both qsv encoders and decoders use 4 as the default value of
async_depth, let's use 4 as the default value for vpp_qsv filter too.
