From f5e33514e7a879b09fabfeffd78402590225bf47 Mon Sep 17 00:00:00 2001 From: Limin Wang Date: Sat, 18 Apr 2020 12:52:48 +0800 Subject: [PATCH] avcodec/libx264: return immediately if encode_nals return 0 x264_encoder_encode can return 0 with nnal 0. As a result, encode_nals will return 0. In this condition, it's better to return 0 immediately to avoid the following unneeded pict_type and flags setting.
