    My code is as follows.

    $videoFileName = rand('111111', '999999').'_'.time().'.'.$request->file('video1')->getClientOriginalExtension();
    
    $intermediateVideo1 = rand('1111111', '9999999').'_'.time().'.ts';
    
    $intermediateVideo2 = rand('1111111', '9999999').'_'.time().'.ts';
    
    $concatVideoFileName = rand('111111', '999999').'_'.time().'.'.$request->file('video1')->getClientOriginalExtension();
    

    
    exec('ffmpeg -i '.$request->file('video1').' -c copy -bsf:v h264_mp4toannexb -f mpegts '.$intermediateVideo1);
    
    exec('ffmpeg -i '.$request->file('video2').' -c copy -bsf:v h264_mp4toannexb -f mpegts '.$intermediateVideo2);
    
    exec('ffmpeg -i "concat:'.$intermediateVideo1.'|'.$intermediateVideo2.'" -c copy -bsf:a aac_adtstoasc '.public_path('uploads/videos/'.$concatVideoFileName));
    

    
    exec('ffmpeg -i '.public_path('uploads/videos/'.$concatVideoFileName).' -i '.storage_path("assets/image/watermark.png").' -filter_complex "overlay" '.public_path('uploads/videos/'.$videoFileName));
    

    

    
    File::delete($intermediateVideo1);
    
    File::delete($intermediateVideo2);
    
    File::delete('uploads/videos/'.$concatVideoFileName);
    

    
    return response()->download(public_path('uploads/videos/'.$videoFileName));

    18 June 2020, by Wolfgang Enfield

    I am trying to use a webcam Logitech Quickcam 9000 to do IRL stream from a Raspberry 3 using Raspberry Pi OS current version, I have FFmpeg installed and no matter what I try the video resolution is never bigger than 320x240 the webcam can output 1600x1200 the output of v4l2-ctl —list-formats-ext

  • ffmpeg-python error, cannot load mp4 encoder

    19 August 2020, by tristan_jia

    This error came when I just try a simple demo from the page of ffmpeg-python:

    


    import ffmpeg
stream = ffmpeg.input('human_face.mp4')
stream = ffmpeg.hflip(stream)
stream = ffmpeg.output(stream, 'new_human_face.mp4')
ffmpeg.run(stream)


    


    And the output goes like:

    


    ...&#xA;Input #0, mov,mp4,m4a,3gp,3g2,mj2, from &#x27;human_face.mp4&#x27;:&#xA;  Metadata:&#xA;    major_brand     : isom&#xA;    minor_version   : 512&#xA;    compatible_brands: isomiso2mp41&#xA;    encoder         : Lavf58.49.100&#xA;  Duration: 00:00:12.45, start: 0.000000, bitrate: 742 kb/s&#xA;    Stream #0:0(und): Video: mpeg4 (mp4v / 0x7634706D), none, 256x256, 741 kb/s, 20 fps, 20 tbr, 10240 tbn, 10240 tbc (default)&#xA;    Metadata:&#xA;      handler_name    : VideoHandler&#xA;Automatic encoder selection failed for output stream #0:0.

    &#xA;

    I think the most important log is:"Automatic encoder selection failed for output stream #0:0. Default encoder for format mp4 (codec mpeg4) is probably disabled or this build of ffmpeg does not include that codec. Please choose an encoder manually."

    &#xA;

    I've reinstalled the ffmpeg package but the error remains.

    Appended 1:&#xA;Thanks for the comment from @HernánAlarcón:
