When using
ffmpeg -i input1 -i input2 ... -filter_script filter_complex.txt output.mkv
I 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.
-filter_complex_script
