From 9ea6d2149e25d68885a24894bb911077b05388c4 Mon Sep 17 00:00:00 2001 From: James Almer Date: Fri, 30 Aug 2019 11:37:25 -0300 Subject: avcodec/decode: add a flags parameter to ff_reget_buffer() Some decoders may not need a writable buffer in some specific cases, but only a reference to the existing buffer with updated frame properties instead, for the purpose of returning duplicate frames. For this, the FF_REGET_BUFFER_FLAG_READONLY flag is added, which will prevent potential allocations and buffer copies when they are not needed.
