  • Multiple video input to Video grid using vstack and hstack in ffmpeg

    22 mars 2017, par Newbee7

    I am trying to find a working example for ffmpeg to combine 4 videos (2x2 stack) and 9 videos (3x3 stack) that are not the same resolution.

    For the 2x2 example I am currently I am using the documentation example but it only works if all videos are the same resolution. see command

    ffmpeg -i top_l.mp4 -i top_r.mp4 -i bottom_l.mp4 -i bottom_r.mp4 -i audio.mp4 \
    -filter_complex "[0:v][1:v]hstack[t];[2:v][3:v]hstack[b];[t][b]vstack[v]" \
    -map "[v]" -an -sn -shortest -f flv rtmp://server/stream

    This does not work with my videos inputs with the following error.

    [Parsed_vstack_2 @ 0000000003245cc0] Input 1 width 1440 does not match input 0 width 1264.

    Also if anyone knows how to do the 3x3 stack, feel free to comment.

  • FFmpeg - Vertical-Scroll Image Overlay for same duration as audio file

    28 décembre 2020, par John Doe

    I want to scroll an image vertically, but I want the animation duration to match an mp3 file, which will be different every time. Here's what I have :

    


    ffmpeg -y -hide_banner -f lavfi -i color=s=1280x720 -loop 1 -i "image.jpg" -filter_complex "[1:v]scale=1280:-2,setpts=if(eq(N\,0)\,0\,1+1/0.01/TB),fps=30[fg]; [0:v][fg]overlay=y=-'t*h*0.01':eof_action=endall[video]" -map "[video]" "output.mp4"


    


    But this always produces a video with duration of 1 minute and 40 seconds, making the animation slow down or speed up accordingly. This is not what I want. I want the output video (and the scrolling animation) duration to match a random mp3 file.

    


    I am using FFmpeg in a Batch file on Windows. Any help would be appreciated.

    


  • avutil/mem : fix doc for reallocs

    avutil/mem : fix doc for reallocs

    The doc says those function are like av_free if size or nmemb is
    
zero. It doesn't match the code. av_realloc() realloc one byte if
    
size is zero, which was added by 91ff05f6ac5 ten years ago.
    
realloc() itself in C is implementation-dependent. Make the doc
    
match the longstanding behaviour.
