• Terminal command to upgrade FFMPEG

  14 avril 2023, par Savvy Turtle

  Everything is still installed but once I upgraded my server from CentOS 7.6 to Cloud Linux FFMPEG does not seem to work anymore.

  


  When I go and debug it in the admin section where you upload a test video and hit debug it shows a toast to upload a video. and on the front end of https://turtle.tube/ users upload a video and it gets stuck at 100% upload and processed.

  


  So I'm wondering whether I need to ugrade FFMPEG to work with Cloud Linux update or If I need to restart it.

  


  Any help would be great thanks.

  Checked Version, looked for terminal command to upgrade FFMPEG to latest stable release of : FFmpeg 5.1.3 "Riemann" or FFmpeg 6.0 "Von Neumann" but have not figured out the command to upgrade yet.

  


  nor the command to restart FFMPEG if that even exist.

  


  Current version of FFMPEG shows :

  


  ffmpeg -version

• Find all video files in directory with FLAC audio codec

  8 septembre 2023, par JSSpen

  Is it possible to search a directory and output a text file listing every video file that has FLAC audio ?

  


  My television doesn't support FLAC so when I run into one I have been converting them with a FFMPEG script but it would be nice to be able to find them all in advance instead of waiting until I hit the problem while trying to play the files. I'm hoping there is a way that doesn't involve just opening every file in Mediainfo and checking manually.

  


  Maybe there is a way to just output all of the Mediainfo information for a directory and then I can just find all FLAC occurrences in a csv sheet ?

  


• Issue with Asynchronous Video Processing and New Window Creation in Windows Forms Application

  2 août 2023, par sadra hoseini

  I have a Windows Forms application that uses FFmpeg for video processing tasks. In this application, I have a textBox2_TextChanged event handler that performs some video processing tasks based on user input.

  


  However, I noticed that when textBox2_TextChanged is called, the UI becomes unresponsive, and it seems like another window is being created but doesn't show up. I suspect that this issue is related to threading.

  


  Here's a simplified version of the problematic code :

  


  // Relevant code snippet:
private async void textBox2_TextChanged(object sender, EventArgs e)
{
    if (listBox1.Items.Count > 0 && int.TryParse(textBox2.Text, out int itemvalue) && int.TryParse(textBox1.Text, out int ratio))
    {
        await Task.Run(() =>
        {
            // Video processing code using FFmpeg (e.g., creating thumbnails).
            // This code seems to cause the UI to freeze and prevent new windows from showing up.
        });
    }
}


  


  Expected Behavior :

  


  When a user enters a valid input in textBox2, the video processing tasks should be executed in the background without freezing the UI. The application should remain responsive, and any new windows, including message boxes or progress dialogs, should show up as expected.

  


  Actual Behavior :

  


  When a user enters a valid input in textBox2, the video processing tasks appear to be running, but the UI becomes unresponsive, and new windows, such as message boxes, do not show up as expected. This makes it challenging to display any progress or error messages to the user during video processing.

  


  Steps to Reproduce :

  


  Open the Windows Forms application.
Add some video files to the list (listBox1) and provide valid input in textBox2.
Observe the UI behavior and any new windows that should be displayed, such as progress dialogs or message boxes.
Additional Notes :

  


  I am using Visual Studio [version] for development.
The application uses FFmpeg for video processing tasks, and I've verified that FFmpeg is functioning correctly.
I've also tried using proper error handling to catch any exceptions, but no exceptions are thrown during the video processing tasks.
Any help or suggestions on how to resolve this issue and enable new window creation during video processing would be greatly appreciated. Thank you !
