TypeError: expected str, bytes or os.PathLike object, not OutputStream while merging two mp4 files

[sakshi-loomanalytics]

I am trying to merge two video files pretending not all the video files would have audio stream and trying to handle it by adding an audio stream when it doesn't exist.

`def merge_videos(file_paths:list, outfile_path:str):

input_streams = []
print("Destination Path: ", outfile_path)

for i, file in enumerate(file_paths):
    print("Source file path: ", file)
    filename = str(file).split("/")[-1]
    input_stream = ffmpeg.input(file)
    audio_stream = ffmpeg.probe(file, cmd = 'ffprobe', select_streams='a')

    if not audio_stream['streams']:
        audio_length = ffmpeg.probe(file)["format"]["duration"]
        print(f"Adding audiostream to file {filename} of audio length ", audio_length)
        base = ffmpeg.input(f'aevalsrc=0:d={audio_length}', f='lavfi')
        concat_file = ffmpeg.concat(input_stream, base, v=1, a=1, unsafe=True)
        print("added successfully")

        video_streamed_file = ffmpeg.output(concat_file, file.split(".")[0]+"_3."+file.split(".")[1], format = "mp4")
        video_streamed_file.run()
        input_stream = ffmpeg.input(video_streamed_file)

        print(ffmpeg.probe(file.split(".")[0]+"_3."+file.split(".")[1]))

    input_video_stream = input_stream.video
    input_audio_stream = input_stream.audio
    input_streams += (input_video_stream, input_audio_stream)

merged_stream = ffmpeg.concat(*input_streams, v=1, a=1).node
print(merged_stream)
new_path = outfile_path.split(".")[0] + "_3." + outfile_path.split(".")[1]
video = merged_stream[0]
audio = merged_stream[1].filter('volume', 0.8)
output = ffmpeg.output(video, audio, new_path).run()`

Following is the output:

I tried to look into the library documentation, FFMPEG documentation, Googling, ChatGPT as well but couldn't find the solution. Thank you
