  • ffmpeg save difference between 2 videos to file

    10 août 2020, par 0x-1

    I'm currently trying to learn everything related to videos and encountered a problem that I need help with.

    


    The Question is : How can I save the difference between 2 videos to a seperate file with ffmpeg ?
    
For example here is the ffplay command I'm trying with :
(Source : https://superuser.com/questions/854543/how-to-compare-the-difference-between-2-videos-color-in-ffmpeg)

    


    ffplay -f lavfi "movie=left.mp4,setpts=PTS-STARTPTS,split=3[a0][a1][a2];
            movie=right.mp4,setpts=PTS-STARTPTS,split[b0][b1];
            [a0][b0]blend=c0_mode=difference[y];
            [a1]lutyuv=y=val:u=128:v=128[uv];
            [y][uv]mergeplanes=0x001112:yuv420p,pad=2*iw:ih:0:0[down];
            [a2][b1]hstack[up];[up][down]vstack"


    


    In this case I would want to have the bottom left video saved to a new file.
    
Can someone help me get together the right ffmpeg filter and explain the proccessing of ffmpeg ?

    


  • PHP ffmpeg - save mp4 as H.264 in Baseline profile

    2 mai 2020, par Pikaboo

    I'm trying to play a mp4 file in android but it's not working.

    



    According to Android VideoView Cannot play video mp4

    



    the file needs to be H.264 in Baseline.

    



    I don't know what the hell this means.

    



    This is the PHP code I'm using to create mp4 :

    



    $videoname = str_replace('.gif', '.mp4', $picname);
$ffmpeg = FFMpeg\FFMpeg::create(array(
    'ffmpeg.binaries'  => 'ffmpeg/bin/ffmpeg.exe',
    'ffprobe.binaries' => 'ffmpeg/bin/ffprobe.exe',
    'timeout'          => 6600, // The timeout for the underlying process
    'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
), $logger);

$video = $ffmpeg->open('memes/' . $folder . '/' . $picname);
$video
    ->save(new \FFMpeg\Format\Video\X264(), 'memes/' . $folder . '/' . $videoname);


    



    How can I set it to be H.264 in Baseline profile ?

    


  • How to save only the error message in a log file ?

    24 septembre 2021, par user12733526

    ffmpeg ... -loglevel +error FFREPORT=file=test.log

    


    ffmpeg ... -FFREPORT=file=test.log:level=verbose

    


    ffmpeg ... FFREPORT=file=test.log:level=error

    


    None of these work.

    


    This works :
ffmpeg ... -loglevel +error -report =file=test.log

    


    But it does save everything in the log file and not only the error message, and the log file created contains a different name.
