From d914da3bb62b58e0cb7c2cdbe56d1a97111c94e6 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sun, 25 Apr 2021 01:43:26 +0200 Subject: [PATCH] avcodec/v408enc: Avoid copying packet data, allow user-supplied buffers When the packet size is known in advance like here, one can avoid an intermediate buffer for the packet data by using ff_get_encode_buffer() and also set AV_CODEC_CAP_DR1 at the same time.
