  • 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.

  • ffmpeg - rendering images and sound into video with transparent background

    22 septembre 2013, par Adam

    I got lots of images and a sound file.

    I want to convert all these images into a video (with the wav file as the sound of the movie).
    The images have a transparent background and I want the movie's background to be transparent too.

    How do I tell ffmpeg to render with a transparent background ?

    P.S - I keep getting the following error :

    Error while opening encoder for output stream #255:0 - maybe incorrect parameters such as bit_rate, rate, width or height

    Sincerely,

    Adam.

  • Video with background image

    23 novembre 2012, par Gabriele Murari

    since my video doesn't respect the safe area i thought to make it smaller and fill the background area (the resulting video must be 720x576 px) with a still image.

    So i've created a movie out of a still image (loop_video.mpg) and then i tried to mix it with my input video using it as a watermark. Doing so i lose the audio stream that comes from my input video.

    here my code :

    ffmpeg -i loop_video.mpg -vf \"movie=input.mpg, scale=648:519 [wm];[in][wm] overlay=36:28 [out]\" -b:v 4096k -bufsize 8192k -minrate 2048k -maxrate 8192k -y -t 10 out.mpg

    So i tried to mix the two and keeping just the audio stream of my input video, and then watermarking again, but i have a significant delay between video and audio stream. It seems that the watermark starts after 1 second :

    ffmpeg -i loop_video.mpg -i input.mpg -map 0:0 -map 1:1 -vf \"movie=input.mpg, scale=648:519 [wm];[in][wm] overlay=36:28 [out]\" -b:v 4096k -bufsize 8192k -minrate 2048k -maxrate 8192k -y -t 10 out.mpg

    Someone could help me ?

    Thanks so much
