  • FFMPEG output from motion detection is gray

    13 septembre 2019, par Eternal_Dusk

    I have taken footage I recorded and wanted to use FFmpeg to cut out still frames of the file, however, I just get a file of the same size, but it is all grayed out.

    Command Used :

    ffmpeg -i video.mp4 -vf "select=gt(scene\,0.0003),setpts=N/(30*TB)" output.mp4\

    Output :
    enter image description here

    This is gameplay of MTG Arena btw

    When I run this in FFplay, however, it looks normal.

    Still, however, no cuts or removal happen, as it is still the same length video.

    At this point I have two questions.

    1) How do I cut frames with no motion in FFmpeg

    2) Why does this footage appear gray.

    My video player is MPC-HC

  • Video freezes when buffer filling

    3 septembre 2021, par pablo Fiscella

    I need to play a video all day without stopping. It works fine until it reaches the full gig (-fs 1000M).
I do not know if it is possible to restart. The loop works but when after an hour it cuts out.

    


    ffmpeg -fflags +genpts -stream_loop -1 -re -i /home/pi/Videos/carteleraMP4.mp4 -vcodec copy -f avi -an -fs 1000M udp://239.0.1.23:1234


    


    When size reaches 1000M the video stops

    


    frame=21395 fps= 24 q=-1.0 size=  175120kB time=00:14:51.43 bitrate=1609.3kbits/frame=21407 fps= 24 q=-1.0 size=  175214kB time=00:14:51.93 bitrate=1609.3kbits/bitrate=1609.3kbits


    


  • ffmpeg - Video longer than audio after having combined image and audio to video

    21 octobre 2017, par Grant SYNKOP

    I wrote code to combine several audio files with 1 image, into WebM video. (audio1 combined with default jpg, audio2 combined with default jpg, etc).

    The problem is that after this, video length is 25 seconds superior to audio length (so audio cuts 25 seconds before the end of the video).

    Is there a way to stop the video at the exact same time of the audio ? Here is the code I used (I launch a BAT command file)

    @echo off  
    
for %%F in (*.ogg) do (  
    
  ffmpeg -loop 1 -framerate 1 -i "default.jpg" -i "%%F" -acodec libopus -b:a 384k -vcodec libvpx-vp9 -lossless 1 -speed 4 -vf scale=1280x720 -shortest "%%F.webm" 
    
)
