Subject: [FFmpeg-devel] [PATCH] lavfi/vf_vpp_qsv: set the default value of async_depth to 4
Date: Fri, 24 Nov 2023 15:00:55 +0800
Message-ID: <20231124070055.1770219-1-haihao.xiang@intel.com> (raw)
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.
