使用ffmpeg将视频转换为hls后，新视频没有屏幕只有音频

如何解决使用ffmpeg将视频转换为hls后，新视频没有屏幕只有音频

我在创建 HLS 流时遇到问题，有时我创建的视频只有音频并且显示黑屏下面是我的代码

/opt/nodejs/ffmpeg -i "https://******-v1-post-content.s3.us-east-
2.amazonaws.com/104/posts/win/video/item-1615842876280.mov" -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls /tmp/item-1615842876280.m3u8

命令的输出
