>我从分辨率为 1920x816 的视频文件中提取了一些剪辑，名为 ca0.mp4...ca9.mp4 使用命令
ffmpeg -i ./ca.mkv -ss 00:53:24 -t 00:01:30 ca0.mp4
然后我创建了一个黑色视频
ffmpeg -f lavfi -i color=black:s=1920x816:r=24000/1001 -f lavfi -i anullsrc -ar 48000 -ac 2 -t 00:00:02 empty.mp4
现在我想用它们之间的黑色视频来连接剪辑。因此，我创建了一个文件列表.txt：
file 'ca0.mp4'
file 'empty.mp4'
file 'ca1.mp4'
file 'empty.mp4'
file 'ca2.mp4'
file 'empty.mp4'
file 'ca3.mp4'
file 'empty.mp4'
file 'ca4.mp4'
file 'empty.mp4'
file 'ca5.mp4'
file 'empty.mp4'
file 'ca6.mp4'
file 'empty.mp4'
file 'ca7.mp4'
file 'empty.mp4'
file 'ca8.mp4'
file 'empty.mp4'
file 'ca9.mp4'
并尝试了命令
ffmpeg -f concat -i list.txt -c:v qtrle -c:a copy ca.mp4
但是，我得到以下输出：

谁能告诉我，我做错了什么？
因为所有文件都已经从 .mkv 转换为.mp4
您可能只需要复制视频编解码器
ffmpeg -f concat -i list.txt -c:v copy -c:a copy ca.mp4
它还将加快该过程
