Help with concat diffrent media types together

[Nosh-Ware]

import ffmpeg


input_still = ffmpeg.input("C:/Users/Nosh/Desktop/sample/1.mp3")
input_audio = ffmpeg.input("C:/Users/Nosh/Desktop/sample/1.jpg")

(
    ffmpeg
    .concat(input_still, input_audio, v=1, a=1)
    .output("output.mp4")
    .run(overwrite_output=True)
)

I am trying to concat an audio (sans video stream) and an image (sans audio stream) together. It seems to not like this, which after research seems to be because the image file has no audio stream and vice versa. How do I make this work? How do I make it show the image for the entire duration of the audio clip? Here is the longer output for more context:

Same problem here. Adding audio and still images streams in the same file it is a nightmare. Each audio format has its nuances, and it takes a lot of metadata fine tuning to get it compatible. Can your python wrapper make things easier with some smart functions?

I guess that would be a question for the devs, not me. I resorted to just calling the CLI directly myself, and it works reasonably well. If this isn't already planed, could smart functions be considered for this module in some way?

Thanks for your reply

Your welcome. I guess a good holdover for now would just be switching that the CLI entirely as there is more documented support and tutorials if you find that the features you need refuse to work. At least that's what worked for me...

No need to abandon ship though if the module works for what you need it to do. When it works it works a lot better.
