ffmpeg | branch: master | James Almer <jamrial at gmail.com> | Fri Jan  8 17:47:41 2021 -0300| [a423bc9dc294c32e6162b900b58b1cc2d3c3328d] | committer: James Almer

ffmpeg_opts: remove lowres check

The st->codec values are updated based on the lowres factor by
avformat_find_stream_info() when it runs an instance of the decoder internally,
and the same thing happens in ffmpeg.c when we open ist->dec_ctx with
avcodec_open2(), so these assignments are redundant.
