Concat for varying length

[Owez]

I'd like to concatinate a non-fixed amount of audio-video streams together. I currently have a list like so of paths corrosponding to v1, a1, v2, a2, v3, a3 etc which may be varied in length:

x  = ["1.mp4", "1.mp3", "2.mp4", "2.mp3"]

And i'd like to concatinate these. I was thinking something like:

ffmpeg.concat(*x, v=1, a=1).output("output.mp4").run()

But it apparently only accepts a ffmpeg.nodes.FilterableStream as seen in this traceback:

Traceback (most recent call last):
  File "redata.py", line 180, in <module>
    ffmpeg.concat(*videostream, v=1, a=1).output("playlist.mp4").run()

TypeError: Expected incoming stream(s) to be of one of the following types: ffmpeg.nodes.FilterableStream; got <class 'str'>

Any help would be appreciated, I cant seem to get it to work!

Made an error by not using ffmpeg.input(path), whoops! Closing

Kann you please spezifiy what you dind wrong and how to fixed it?

[payalrajguru]

stream = ffmpeg.input('C:/My_Work_Quixy/yolov5_final/yolov5_env/runs/detect/exp/Crossroads.mp4')

stream = ffmpeg.output(input,'C:/My_Work_Quixy/yolov5_final/yolov5_env/data/video_outputs/out.mp3')

ffmpeg.run(stream)

this is my code everything is correct still showing error , TypeError: Expected incoming stream(s) to be of one of the following types: ffmpeg.nodes.FilterableStream; got <class 'builtin_function_or_method'>
