    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source

  • ffmpeg command with action subprocess

    1er juillet 2018, par MathJunkiey

    I want to run this command in a python script

    cmd = 'ffmpeg -ss ' + start_time + ' -i remove_takeoff.mp4 -filter_complex "[0]trim=0,setpts=PTS-STARTPTS[b];[b][0]overlay=shortest=1" -shortest -c:a trimmed_takeoff.mp4'

    I’m using the following code snippet

    import subprocess
    
import shlex
    

    
cmd = # the command
    
suprocess.call(shlex.split(cmd))

    I’m getting the following error

    Trailing options were found on the commandline.

    The above error occurring because the shlex.split command is converting the double quotes of the part into single quote. How to avoid this from happening. Can anyone suggest me a solutions for this problem.

    Check the full error trace below.

  • How can I record the desktop action to a video file with ffmpeg without showing the ffmpeg console window ?

    24 décembre 2018, par Dubi Duboni

    Tried this method either by calling it from the constructor or a button click event :

    private void StartRecordingDesktop()
    
        {
    
            Process process = new Process();
    

    
            // Stop the process from opening a new window
    
            process.StartInfo.RedirectStandardOutput = true;
    
            process.StartInfo.UseShellExecute = false;
    
            process.StartInfo.CreateNoWindow = true;
    
            process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    

    
            // Setup executable and parameters
    
            process.StartInfo.FileName = @"d:\SavedScreenshots\ffmpeg.exe";
    
            process.StartInfo.Arguments = "-f gdigrab -framerate 24 -i desktop -preset ultrafast -pix_fmt yuv420p testwithforms.mp4";
    

    
            // Go
    
            process.Start();
    
        }

    Two problems :

    1. It’s not recording when I shut down the application there is no video file on the hard disk.

    2. When I shut down the application sometimes it leaves a working exe file parto f the ffmpeg in the background that make the mouse cursor to shake a bit stuttering.

    What I want is to start/stop recording without showing the ffmpeg console window. The idea in the end is to make some identification of the recording mode if recording or not using a tray icon as indiacator.
