【中文标题】带有水印和音频的 FFmpeg 连接“过滤器图描述中的流说明符不匹配任何流”。

【英文标题】：FFmpeg concat with watermarks and audio "stream specifier in filtergraph description matches no streams."

【发布时间】：2016-03-26 20:03:37

【问题描述】：

我正在尝试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.

这是我最近一次尝试的完整输出：

另外，如果有人可以帮助我在整个连接视频上使用单个 mp3 音频输入来完成此操作，那也会很有帮助。

【问题讨论】：

segment0没有视频流，但是你在concat中引用了它。

@Mulvya 确实。谢谢。

【参考方案1】：

另外，如果有人可以通过单个 mp3 音频输入帮助我做到这一点 在整个连接的视频中，这也很有帮助。

如果您将 mp3 输入为 n+1 输入，则应在末尾添加-map n+1:a。

实际上你写-map "[v]"是你真的想得到还是需要写-map [p]？
