ffmpeg -i input1 -i input2 ... -filter_script filter_complex.txt output.mkvI can't seem to get the stream from the filter_complex.txt file to be recognized by ffmpeg. If I add
-map [v], then it doesn't recognize the
[v]like it would normally and says there's an unconnected output.
This is less important, but I haven't found a way to do something like
ffmpeg -i inputs.txt ...to avoid the character limit yet, so if you know a way to do that, that would be nice.
Reason: I'm trying to use ffmpeg to overlay many images (~100) onto a video at various points and need to use files so I'm not going over the command line limit of 2k-8k characters in windows.
