audio - FFmpeg concat与水印和音频“filtergraph描述中的流说明符匹配没有流。”

我正在尝试使用一系列水印连接任意数量的视频：

ffmpeg -i segment0.mp4 -i segment1.mp4 -i ... segmentn.mp4 -i end.mp4 -i ../../watermark/watermark1280/watermark_%05d.png -filter_complex "[0:v][1:v]...[n:v]concat=n=n:v=1:a=0 [v], [v] overlay [p]" -map "[v]" -an -y output.mp4

我收到以下错误：

Stream specifier ':v' in filtergraph description [0:v][1:v]...[n:v]concat=n=n:v=1:a=0 [v], [v] overlay [p] matches no streams.

以下是我最近尝试的完整输出：

另外，如果有人可以通过整个连接视频的单个mp3音频输入来帮助我这样做，那也很有用。
