• Process won't stop

  14 mai 2018, par Srdjan M.

  The process goes in infinite loop or it’s waiting something and I don’t know what. It won’t pass WaitForExit methode.

  FFmpeg :

  -ss 0 -i output.mp4 -t 10 -an -y test.mp4

  C# Code :

  using (Process process = new Process())
  
  {
  
       process.StartInfo.UseShellExecute = false;
  
       process.StartInfo.RedirectStandardOutput = true;
  
       process.StartInfo.RedirectStandardError = true;
  
       process.StartInfo.FileName = FileName; // ffmpeg.exe
  
       process.StartInfo.Arguments = Arguments; //-ss 0 -i output.mp4 -t 10 -an -y test.mp4
  
       process.Start();
  
       process.WaitForExit(); // stops here and waits
  
  
  
       return process.StandardOutput.ReadToEnd();
  
  }

  Edit :

  Adding -loglevel quiet to my ffmpeg query made my problem disappear. Why ?

• Stop/cancel execution of FFmpeg command

  5 juin 2018, par user155

  There is FFmpeg Static (binary) available for Android and we can stop/cancel some FFmpeg execution (command) while it’s doing something https://github.com/WritingMinds/ffmpeg-android-java/issues/33

  But I want to use FFmpeg shared libraries and JNI, I found next library https://github.com/IljaKosynkin/FFmpeg-Development-Kit (it works ok)

  But there is no option to stop execution of FFmpeg command (or killing the process)

  We use Java native run method there to start execute some command :

  Java :
  https://github.com/IljaKosynkin/FFmpeg-Development-Kit/blob/master/JNI/app/src/main/java/com/example/ilja/jni/VideoKit.java#L57

  and then in C we call FFmpeg’s main method :

  C :
  https://github.com/IljaKosynkin/FFmpeg-Development-Kit/blob/master/JNI/app/jni/videokit.c#L41

  How can I stop/cancel some FFmpeg executing after I called Java run and C main methods ?

• How do I make youtube-dl or streamlink stop after a certain period of time when downloading a live stream

  13 janvier 2020, par Programmer4Life

  I’m the unofficial historian for a popular 24/7 live feed. I wrote a script to use streamlink (fork of livestreamer) to download the stream constantly. Then i have a script to upload the captured video to YouTube as unlisted for the stream owner. I use a shell script and have the file names be dates and times.

  I’ve also used youtube-dl. For both, The maximum captured time appears to be 6 hours because it’ll stop after that amount of time. To address this, I wrote a script to restart the capture when it stops after sleeping for 30 seconds (safety in case of runaway loop) so this isn’t an issue either.

  What i am trying to do is to either set my stream capture (whether it’s youtube-dl or streamlink it doesn’t matter) to stop after a shorter interval, say 2 hours. I could also split up the file into 3 parts but i don’t know if that would require re-encoding. If it does, that’s not an option because all of this is done on a VPS with limited resources.

  The reason I am trying to split up the files or capture in a shorter time period is because 6 hours is too dang long to easily navigate a YouTube video. On mobile, trying to seek to a specific time is near impossible. Desktop isn’t much easier because you need to be very precise.
