我遇到了无法setsar=sar=1/1在我创建的所有视频流上进行设置的问题......
例如
ffmpeg -i {file} -c:v libaom-av1 -pix_fmt yuv420p
-map 0:v:0 -filter:v:0 scale=-2:144,setsar=sar=1/1
-map 0:v:0 -filter:v:1 scale=-2:240,setsar=sar=1/1
-init_seg_name "init-\$RepresentationID\$.\$ext\$"
-media_seg_name "chunk-\$RepresentationID\$-\$Number%05d\$.\$ext\$"
-dash_segment_type auto
-use_template 1 -use_timeline 1 -seg_duration 10
-adaptation_sets "id=0,streams=v id=1,streams=a"
-f dash /mkv_f/dash.mpd
一个输入文件，需要在输出端获得多个视频流。每个视频流应具有SAR 1:1、 和DAR自适应（自动）。
144/240尝试过将分辨率转换为不同的文件setsar=sar=1/1。它可以工作，但是当你需要转换为多个文件时。不允许你设置参数setsar=sar=1/1

如何setsar=sar=1/1在所有视频流上设置？并且 DAR 将自动设置...
