  • How to write ffmpeg windows command for file path inside double quotes option

    19 février 2021, par Herahadi An

    please help

    


    I want to use ffmpeg for my c # application but an error appears

    


    this is my code

    


    videoPath = @"c:\location\in.mp4";
tempVideoPath = @"c:\another_location\out.mp4";

process.StartInfo.FileName = @"ffmpeg.exe";
    
process.StartInfo.Arguments = "-loop 1 -i \""+tbBGFrame.Text+ "\" -vf \"movie=\""+videoPath+ "\",scale=1900:-1[inner];[in][inner]overlay=70:70:shortest=1[out]\" -y \""+tempVideoPath+"\"";


    


    the problem is inside movie parameter. i have to include video path inputed by user but its give an error because its already double quote exist before.

    


    its successfully if i try on windows cmd like this

    


    > cd "C:\Users\Toshiba\Pictures\test vcp\input_mp4_dir\"
> ffmpeg.exe -loop 1 -i Coronavirus00000000.jpg -vf "movie=input.mp4,scale=1180:-1[inner];[in][inner]overlay=70:70:shortest=1[out]" -y out.mp4


    


    but how i can run that command wihtout change directory to input.mp4 directory ?

    


  • How does ffmpeg use concat of filter in C？

    12 mai 2022, par Jeycri

    It's OK for me to use the command line like this.

    


    ffmpeg -i test1.mp4 -i test2.mp4 -filter_complex "movie='test1.mp4',scale=640:360[v1];movie='test2.mp4',scale=640:360[v2];[v1][v2]concat" testout.mp4


    


    This is my configuration code.

    


    AVFilterInOut* inputs = avfilter_inout_alloc();
AVFilterInOut* outputs = avfilter_inout_alloc();
...
avfilter_graph_parse_ptr(filter->filterGraph, 
"movie='test1.mp4',scale=640:360[v1];movie='test2.mp4',scale=640:360[v2];[v1][v2]concat", 
&inputs, &outputs, NULL)
avfilter_graph_config(filter->filterGraph, NULL)


    


    Reported error

    


    [h264 @ 0000026dfecef780] Application has requested 17 threads. Using a thread count greater than 16 is not recommended.

Output pad "default" with type video of the filter instance "in" of buffer not connected to any destination


    


    How can I configure the filter correctly？
