  • Use ffmpeg to concatenate a video and a timelapse

    26 décembre 2022, par tudors

    Input 1 : I used my phone to record a 25 fps movie with 1920x1080 resolution. There is sound.

    


    Input 2 : I used ffmpeg to create a timelapse movie i.e. 25 fps made out of 1920x1080 JPEGs. There is no sound.

    


    When I tried to concatenate them however, the result was a mess : It seems some fine detail is not matching between the two inputs, because the resulting video squishes the time lapse down to just 1 frame at the end.

    


    I have also tried this by first removing sound from video 1, so that both videos are soundless, and this does not give a different result.

    


    How can I tell ffmpeg that the two inputs are not incongruent, so as to achieve a correct 25 fps 1920x1080 video using all the frames from both inputs ?.

    


  • Gphoto2 live view with nikon dslr5100 pipes to ffplay for 3 seconds then dies

    30 avril 2020, par Will Simpson

    I am trying to use my DSLR camera with OBS.
I have installed Gphoto2 on mac and have managed to get a connection to the camera.
Now I am trying to get some kind of live view window that I can then capture in OBS.

    



    The problem is when I use the following command, the camera makes like it is about to go into movie mode, the window opens and then the image begins streaming for usually about 4 seconds before it freezes.

    



    gphoto2 --port usb:250,006 --capture-movie --stdout | ffplay -i pipe:0 -vcodec mjpeg


    



    I specify the port because I also have my iphone camera in another window in OBS

    



    Does anyone have any suggestions ?

    


  • ffmpeg encode video with different rates [on hold]

    12 août 2013, par alexis

    I have two videos. I make this videos with the following codes :

      ffmpeg -r 5 -f image2 -i "b%d.png" -c:v mpeg4 -q:v 5 -an a.avi 
    
  ffmpeg -r 15 -f image2 -i "b%d.png" -c:v mpeg4 -q:v 5 -an b.avi

    As you can see, the only difference is the rate. Now I want to concatenate them. Following the other post I use this :

      ffmpeg -i "concat:a.avi|b.avi" -c copy movie2.avi

    However the resulting movie shows the "b.avi" part much more slower. Actually no difference of speed is appreciated between "a" and "b" parts. How can I keep the differences of speed in the resulting movie ?

    Maybe I have some conceptual misunderstanding about rate... but the thing is that I want the "b.avi" part to be faster than the "a.avi" part.
