我想将输入 -i input%3.png 输入到过滤器图中，然后在 -filter_complex 中使用这些输入，就像我通常使用 [x:v] 或 [0:v:x] 一样，其中 x 是索引。这两个都不起作用，抛出像 Invalid file index 1 in filtergraph description 或 stream specifier :v:1 in ... matches no stream 这样的错误
编辑:日志和命令，根据要求。ffmpeg -i background.mkv -i comment%3d.png -filter_complex_script filter_complex.txt background-comments.mkv过滤器图在错误消息中完整显示，但要点是:[0:v][1:v] overlay=0:0:enable='background(t,0,1)' [tmp0]; [tmp0][2:v] overlay=0:0:enable='background(t,1,2)' [tmp1]; [tmp1] ...

最佳答案
应该是 [0:v][1:v] overlay=0:0:enable=...但它是 [0:v][1:v:1] overlay=0:0:enable=...因为图像输入有一个视频流。
关于ffmpeg 将图像与 %3.png 格式分开，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/62903699/
