  • FFMPEG Error -1414092869 : Immediate exit requested

    8 juillet 2019, par Manity

    Hello i am using ffmpeg to play 4 videos at the same time.
    I am using a wpf/c# .net 4.7.2 wrapper for ffmpeg to do this.

    Occasionally get this error message, and the application just shuts down.
    there are no errors or exceptions thrown other than this one logged.

    Error -1414092869 : Immediate exit requested

    I have searched for a meaning to this error but can find nothing other than a vague reference to an android video player which does not provide me with any information at all.

    Can anyone shed any light at all, anything at all on the meaning of and cause of this above error and how it might be resolved ?.

  • Efficient command line to crop a video, overlay another crop from it and scale the result with ffmpeg

    26 mai 2018, par Witek

    I need to convert many videos in such a way that I take 2 different crops from each frame of a single video, stack them one over the other and scale down the result, creating a new smaller video.
    I want to convert this fullHD frame (two crop areas are marked red) to this small stacked frame.

    Right now I use the following code :

    ffmpeg  -i "video.mkv" -filter:v "crop=560:416:0:0" out1.mp4
    
ffmpeg  -i "video.mkv" -filter:v "crop=560:384:1060:128" out2.mp4
    
ffmpeg  -i out1.mp4 -vf "movie=out2.mp4[inner]; [in][inner] overlay=0:32,scale=280:208[out]"  -c:v libx264 -preset veryfast -crf 30 result.mp4

    It works but it is very inefficient and requires temporary files (out1 and out2). And the problem is I have over 100.000 of such videos (they are big and stored on a NAS and not directly on my computer’s HDD). Converting all of them with a Windows batch script (for loop) will take...48 days. Can you help me to optimize the script ?
