ffmpeg conversion .dav to any video files

Question

I am trying for days to convert .dav file (file generated by dvrs [image recorders]). I have tried several variations with ffmpeg and can not succeed.<

Answer 1

I have gone through above process and it was quite successful, only limit was in performing the operation with multiple files in batch. So, I came up with following solution.

1. First install ffmpeg

sudo apt install ffmpeg

2. Save following as convert.py then

import subprocess
from os import listdir
from os.path import isfile, join
onlyfiles = [f for f in listdir(".") if isfile(join(".", f))]

c=1
for i in onlyfiles:
    
    c=c+1
    list_dir = subprocess.Popen(["ffmpeg", "-y","-i",i,"-c:v","libx264","-crf","24",i[:-4]+".mp4"])
    list_dir.wait()

3. Run the code python convert.py
