  curl: (60) SSL certificate problem: certificate has expired
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.
HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

• FFMPEG M3U8 Download Is Shortened When Processed

  19 décembre 2022, par Devin Dixon

  I am downloading an m3u8 stream with FFMPEG as such :

  


  timeout 60m ffmpeg -i [feed_url] -movflags isml+frag_keyframe+faststart -bsf:a aac_adtstoasc -vcodec copy -c copy [save_file].mp4


  


  

  • The timeout will automatically end the stream after 60. minutes

  


  • The -movflags isml+frag_keyframe+faststart makes sure the moov atom is present for partial downloads and if the stream is cut off.

  


  


  This works fine when I play it in Quicktime or Safari.The stream is then uploaded to another server and it gets processed with this ffmpeg command :

  


  ffmpeg  -i [input_file] -y  -f mp4 -pix_fmt yuv420p -c:v libx264 -c:a aac -filter_complex "scale='if(gt(iw,1920),1920,-1)':'if(gt(ih,1080),1080,-1)':force_original_aspect_ratio=decrease" -crf 20 -movflags faststart -max_muxing_queue_size 9999 -attempt_recovery 1 -max_recovery_attempts 3 -f mp4 [output_file]


  


  When the above command is run, sometimes this error occurs :

  


  [mov,mp4,m4a,3gp,3g2,mj2 @ 0xaaaafcd63b70] Packet corrupt (stream = 0, dts = 53801910).=  64x

  When this error occurs, the video is cut short. If the full video is 60 minutes that error occurs at the 10 minute mark, the converted video will only be 10 minutes. What is that error and how can I get ffmpeg to stop cutting the output video short ?

  


• How to correctly close a console application using the youtube-dl process to download Twitch stream whenever I want

  24 juin 2023, par ElPavlillo

  The test program has the following code :

  


  string url = "https://www.twitch.tv/ricoy";
string outputPath = @"D:\ruta_del_archivo_salida.mp4";

ProcessStartInfo startInfo = new ProcessStartInfo
{
    FileName = "youtube-dl",
    Arguments = $"-f best -o \"{outputPath}\" \"{url}\"",
    //RedirectStandardOutput = true,
    UseShellExecute = false,
    CreateNoWindow = true
};

using (Process process = new Process())
{
    process.StartInfo = startInfo;
    process.Start();

    //var output = process.StandardOutput.ReadToEnd();
    //process.WaitForExit();

    Console.Read();
    KillProcessAndChildren(process.Id);
}

static void KillProcessAndChildren(int pid)
{
    // Cannot close 'system idle process'.
    if (pid == 0)
    {
        return;
    }
    ManagementObjectSearcher searcher = new ManagementObjectSearcher
            ("Select * From Win32_Process Where ParentProcessID=" + pid);
    ManagementObjectCollection moc = searcher.Get();
    foreach (ManagementObject mo in moc)
    {
        KillProcessAndChildren(Convert.ToInt32(mo["ProcessID"]));
    }
    try
    {
        Process proc = Process.GetProcessById(pid);
        proc.Kill();
    }
    catch (ArgumentException)
    {
        // Process already exited.
    }
}


  


  The problem is that when I press de key in the console the youtube-dl process gets kill and also de ffmpeg but the file is left with .part extension and does not work.

  


  I was expecting the code to left a .mp4 file but for reason it does not.
