• Can't seem to find a proper way of splitting a huge (really huge) video into 1 hour chunks without any loss in quality

  31 octobre 2023, par bit_scientist

  I have backed up a video from Milestone system in mkv format. It's a 106 hours-video with 37 GB size. I have searched for way to split into one-hour chunks without any quality loss. However, I am facing two problems :

  


  

  1. A python code with subprocess has produced videos in arbitrary lengths such as 11 minutes, 1.5 hours, 55 minutes, etc.

  


  2. The produced videos look corrupt. When played I can't use forward or backward (5s) functions, it instantly leaps to the end of the video. There is no such an issue when original video is played.
Here is the code I used to do the job :

  


  


  import subprocess
import math

input_file = "video.mkv"
output_prefix = "output"
segment_duration = 60 * 60

ffprobe_command = [
    "ffprobe",
    "-v",
    "error",
    "-show_entries",
    "format=duration",
    "-of",
    "default=noprint_wrappers=1:nokey=1",
    input_file,
]
total_duration = float(subprocess.check_output(ffprobe_command))

num_segments = int(total_duration / segment_duration)

for i in range(num_segments):
    start_time = i * segment_duration
    output_file = f"{output_prefix}_{i + 1}.mkv"

    ffmpeg_command = [
        "ffmpeg",
        "-ss",
        str(start_time),
        "-i",
        input_file,
        "-t",
        str(segment_duration),
        "-c:v",
        "copy",
        "-c:a",
        "copy",
        output_file,
    ]

    subprocess.run(ffmpeg_command)


  


  I also tested with ffmpeg command with similar output lengths or some other failures such as Too many packets buffered for output stream 0:0.

  


  Could someone suggest a better way to do the splitting in any language ?
I don't mind spending too much time to split the video, all I need is one-hour videos without any corruption or quality loss.
I am on a Windows machine if it helps.

• why ffmpeg process successfully terminated with return code of 1 without play anything

  24 juillet 2023, par Exc

  `I tried replacing youtube_dl with yt_dlp and replaced some of the code, the code worked fine but when using the command, the bot doesn't play music but immediately ffmpeg process 15076 successfully terminated with return code of 1

  


  Is there a problem with my code or the ffmpg option or ytdlp option that doesn't support the yt_dlp library ?`
