From 4c5e77e0bf14aa3cb838e788dbaf88441c82e5d2 Mon Sep 17 00:00:00 2001 From: Zhong Li Date: Thu, 11 Oct 2018 17:26:12 +0800 Subject: lavc/qsvenc_jpeg: add async_depth support Currently qsv (m)jpeg encoding is broken. Regression introducing by the commit(id: c1bcd3): fix async support, which requires the minimum async_depth to be 1, instead previous zero. But the default async_depth of qsv (m)jpeg encoding is still initialized (mostly) as zero. This patch also abviously improves qsv (m)jpeg encoding performance due to the default async_depth is changed to 4.
