From bb79853d20a57114ad030c15120c017ed7bd5030 Mon Sep 17 00:00:00 2001 From: Mengkejiergeli Ba Date: Wed, 8 Jun 2022 12:31:56 +0800 Subject: [PATCH] msdkvpp : Use va pool at linux path and system pool for windows We use msdkvpp's own pool to allocate buffers instead of external frame allocator mfxFrameAllocator.
