我在创建HLS流时遇到问题，有时我创建的视频只有音频，并且显示黑屏这是我在下面的代码
/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

我也遇到过这个问题。当尝试使用"-codec:copy"命令复制HEVC视频时，这种情况似乎经常发生。
我找到的一个解决方法是只复制音频流，并通过将"-cocode:copy"替换为"-cocode:a copy"来对视频流进行转码。尽管这种方法可能更加耗时和资源密集，但它仍然有效。
我不是FFmpeg的专家，所以如果有人能详细解释这个问题，那就太好了。
