Now how to edit -metadata:s:v, -metadata:s:a , -metadata:s:s 🤔

Answer 1

import time
import ffmpeg

inputs = "Sample video.mkv"

output = str(round(time.time())) + ".mkv"

datas = {"metadata":"title=Clinton Abraham"}
datas.update({"metadata:s:a":"description="})
datas.update({"metadata:":"comment=TELEGRAM > @DC4_WARRIOR"})

try:
    main = ffmpeg.input(inputs)
    nemo = main.output(output, map="0", **datas, c="copy")
    nemo.run(quiet=True)
    print("PROCESSED SUCCESSFULLY ⚡")
except ffmpeg.Error as e:
    print(e.stderr.decode('utf-8'))
