  • FFMPEG 4 videos merge in one screen [duplicate]

    10 août 2018, par Farukh Zahoor

    This question already has an answer here :

    I found a sample that merge 2 videos on one screen

    ffmpeg.exe -i 1.mp4 -i 2.mp4 -filter_complex "[0:v]scale=iw/2:ih/2,pad=2*iw:ih[left];[1:v]scale=iw/2:ih/2[right];[left][right]overlay=main_w/2:0[out]" -map [out] -map 0:a? -map 1:a? -b:v 768k output.mp4

    I tried this command to merge 4 videos on one screen

    ffmpeg.exe -i 1.mp4 -i 2.mp4 -i 3.mp4 -i 4.mp4 -filter_complex "[0:v]scale=iw/2:ih/2,pad=2*iw:ih[upperleft];[1:v]scale=iw/2:ih/2[upperright];[2:v]scale=iw/2:ih/2,pad=2*iw:ih[lowerleft];[3:v]scale=iw/2:ih/2[lowerright];[upperleft][upperright]overlay=main_w/2:0;[lowerleft][lowerright]overlay=main_w/2:0[out]" -map [out] -map 0:a? -map 1:a? -b:v 768k output.mp4

    But this generates output similar to 1st command having 2 videos merged in one view. I need all 4 videos to be shown on one screen. Additionally I want audio of 1st video file should be used for output. Please guide

    The suggested duplicate link and examples merge videos with exact same quality and takes lot of time to generate output file. I want dimension of video should be changed to half and should quickly generate the output file. The example I shared working fine for 2 videos but not for 4 videos.

  • Pausing a ffmpeg screen capture ?

    21 octobre 2024, par LostXOR

    I have a script to record my screen using ffmpeg :

    



    ffmpeg -video_size 1920x1080 -framerate 60 -f x11grab -i :0.0 -c:v libx264rgb -crf 0 -preset ultrafast video.mkv

    



    I tried using pkill -STOP ffmpeg to pause the recording and pkill -CONT ffmpeg to resume it. The command seems to work correctly, pausing the recording process and later resuming it. However on playback, instead of instantly cutting to when I resumed ffmpeg, the video freezes for the duration I pause ffmpeg. Is there a way I can prevent the video from freezing, and instantly cut to when I resume recording ? (I can upload a sample clip if that would help clarify something.)
