From 1d5ba34249e2a43976586fcbb1171b03bdcca1e0 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sat, 3 Feb 2024 01:11:53 +0100 Subject: avformat/avformat: Remove dead check, write-only assignment For muxers, the internal AVCodecContext is basically unused except in avformat_transfer_internal_stream_timing_info() (which sets time_base and ticks_per_frame) and av_stream_get_codec_timebase() (a getter for time_base). This makes ticks_per_frame write-only, so don't set it. Also remove an always-false check for the AVCodecContext's codec_tag.
