  • FFMPEG : Stream in Stream aka Picture in Picture

    29 janvier 2020, par F O X

    Any chance that i could make picture in picture with ffmpeg (ubuntu) ?

    My single stream is working with this command very well :

    ffmpeg -f lavfi -i anullsrc -rtsp_transport tcp -i rtsp://.......... -b:v 800k -maxrate 900k -bufsize 600k -vcodec copy -crf 35 -preset veryfast -pix_fmt + -c:a aac -f flv rtmp://a.rtmp.youtube.com/live2/........

    Tried several ideas but all of them are using libx264 instead of just -vcodec copy and i don’t know why but with libx264 my bitrate stream and fps are terrible low. So is there any way to just copy both streams and scale one of them to lowerleft corner ?

    Of course i would be using two different streams.

  • Create video from images and audio with varying image durations using FFMPEG ?

    7 janvier 2018, par Muhammad Umer

    What I want to do :

    I’ve x amount of images png/jpg, and I want to show them for varying amount of duration, some longer, and some shorter amount of time.

    • a1.jpg 1st photo stays for 3 seconds
    • a2.png stays for 10 seconds
    • a3.jpg stays till end of audio

    Video should be as long as audio.mp3

    this is my code so far after reading documentation, not sure what’s wrong, I get corrupt video with no sound and only shows last image.

    Also would like to center images if possible.

    ffmpeg -y \
    
  -loop 1 -t 1 -i a1.jpg \
    
  -loop 1 -t 1 -i a2.jpg \
    
  -loop 1 -t 4 -i a3.jpg \
    
  -loop 1 -t 1 -i a4.png \
    
  -loop 1 -t 1 -i a5.png \
    
  -i audio.mp3 \
    
  -c:v libx264 -pix_fmt yuv420p -c:a copy video.mp4
