Combine multiple videos with specific duration
11 août 2020, par Armand KupcisI am going to concat multiple videos so I can get one video file with FFmpeg.


I've found several ways to implement this but all ways I found can't concat with specific duration of each video.


It means they only concat whole videos.


Exactly, what I wanted is to insert video1 into video2 with specific time. While searching several articles related with this, I checked many articles say "It is impossible with ffmpeg".


So I am trying to split video2 into two videos( like video2-1,video2-2) and concat video1, video2-1, video2-2.

How do i extract individual frames from videos using ffmpeg ?
15 novembre 2015, par yzhuI have a bunch of videos downloaded from Youtube and I would like to extract frames from them. The current command I am using is :
ffmpeg -i input.mp4 -an -s qvga %06d.png
But I also want to set the -r and -t option. I want the fps to be the fps of each video, and the duration time is their duration. I know that if I don’t set the -r option, the default is 25 fps.
So could anyone help ? how to add the -r and -t option ? and is there any better and accurate way to obtain individual frames from videos ? Thanks a lot.

ffmpeg save difference between 2 videos to file
10 août 2020, par 0x-1I'm currently trying to learn everything related to videos and encountered a problem that I need help with.


The Question is : How can I save the difference between 2 videos to a seperate file with ffmpeg ?

For example here is the ffplay command I'm trying with :
(Source : https://superuser.com/questions/854543/how-to-compare-the-difference-between-2-videos-color-in-ffmpeg)

ffplay -f lavfi "movie=left.mp4,setpts=PTS-STARTPTS,split=3[a0][a1][a2];
 movie=right.mp4,setpts=PTS-STARTPTS,split[b0][b1];
 [a0][b0]blend=c0_mode=difference[y];
 [a1]lutyuv=y=val:u=128:v=128[uv];
 [y][uv]mergeplanes=0x001112:yuv420p,pad=2*iw:ih:0:0[down];
 [a2][b1]hstack[up];[up][down]vstack"



In this case I would want to have the bottom left video saved to a new file.

Can someone help me get together the right ffmpeg filter and explain the proccessing of ffmpeg ?
