  • FFMPEG Crop with side by side merge

    14 février 2016, par Alan

    I am trying to create a shell/ffmpeg script that can show multiple files after they have been processed using different filters in a side by side / tiled way. An example of desired output would be : https://www.youtube.com/watch?v=DoPuhMRYem4.

    In order to create the desired output I need to crop off the right half of video1 and the left half of video2 and then join them back with [video1+video2] side by side. I have played around with a bunch of different ways of joining them, this does OK :

    ffmpeg -i input1.mp4 -i input2.mp4 -filter_complex "
    
nullsrc=size=800x400 [background];
    
[0:v] setpts=PTS-STARTPTS, scale=400x400 [left];
    
[1:v] setpts=PTS-STARTPTS, scale=400x400 [right];
    
[background][left]       overlay=shortest=1       [background+left];
    
[background+left][right] overlay=shortest=1:x=400 [left+right]
    
" -map '[left+right]' joined.mp4

    How can I modify this to detect the video width (they won’t always be the same width), divide the width in half and crop either the left or right sides off ?

  • ffmpeg : Is this a bug in Xcode ?

    30 avril 2014, par daozhao

    I debug the ffmpeg program on the macosx with xcode.I find a bug with xcode(or lldb)。

    code @ ffmpeg_opt.c-->static int open_input_file(OptionsContext *o, const char *filename)
    #ifdef DEBUG
    av_log(NULL,AV_LOG_INFO,"func :%s(%d) filename :%s \n", __func__,__LINE__,filename) ;
#endif

        if (!strcmp(filename, "-"))  //after step over,the debug windows show filename=NULL.
    
        filename = "pipe :" ;
    

    #ifdef DEBUG
    
    av_log(NULL,AV_LOG_INFO,"func :%s(%d) filename :%s \n", __func__,__LINE__,filename) ; 
    
    //but it can print the correct value。
    
#endif

    you can clone the project from https://github.com/daozhao/FFmpeg.git, and checkout branch(release/2.2withComment) which is include xcode project file. you can debug with FFmpegMakefile targets try it.

    you can see the screen record on https://www.youtube.com/watch?v=3rTLirTGPM4 .

    my OS:10.9.2, xcode:5.1.1
