I am trying to concatenate multiple video files with ffmpeg and python with the following code :-
def story(path):
videos = [f for f in os.listdir(path) if f.endswith(".mp4")]
print(videos)
command = [
"ffmpeg","-y",
"-f","concat",
"-safe","0",
"-i","concat_list.txt",
"-c","copy",
"final.mp4"
]
with open("concat_list.txt","w") as f:
for video in videos:
f.write("file " + os.path.join("assets/story",video) + "\n")
print(os.path.join("assets/story", video))
subprocess.run(command)
os.remove("concat_list.txt")
return "final.mp4"
path = "assets/story" story(path)
it is concatenating videos but the resulting output video file only playing first video properly and rest of the videos are just freeze frame with only audio with following error message :=
on-monotonic DTS in output stream 0:0; previous: 5501744, current: 2442453; changing to 5501745. This may result in incorrect timestamps in the output file.
