  • Using FFMPEG : How to do a Scene Change Detection by audio

    9 janvier 2021, par dantedel

    I have a video that has many scenes, within each scene there are several video cuts with and single unique narator.
I'm trying to split the video to individual scenes based on narator. So far only found only a way using select/scene to get timestamps based on scene video changes.

    


    Using FFMPEG : How to do a Scene Change Detection ? with timecode ?

    


    ffmpeg -i input.flv  \
       -filter:v "select='gt(scene,0.4)',showinfo" \
       -f null \
       - 2> ffout


    


    Is there an equivalent way to get the scene changes by examining changes in audio ?

    


  • ffmpeg with two input rtmp streams with overlay causing 5 sec delay

    13 juin 2019, par GoodStudent

    I’m using ffmpeg on merging two videos, using overlay taking input from two rtmp streams getting lag of 5 seconds in one of the videos in stream3 .

    Below is the command I’ve tried

    ffmpeg -i rtmp://stream1  -i rtmp://stream2  
    
       -filter_complex "[0:v]scale=1280:720;[1:v]scale=320:180[v1];[v0][v1]overlay=eof_action=pass[out1]" 
    
       -map [out1]   -f flv   rtmp://stream3

    I’m expecting less than 1 sec lag in overlay as individual streams are getting less than 1 sec lag
