  • FFmpeg audio doesnt work in converted videos but in pc it does

    28 octobre 2013, par Dirk Swarz

    I use :

    if($ext == "avi" && $convert_avi == true)
    
                    {
    
                        $convert_source = _VIDEOS_DIR_PATH.$new_name;
    
                        $conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
    
                        $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
    
                        $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
    
                        echo exec($ffmpeg_command);
    
                        $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
    
                        $result = @mysql_query($sql);
    
                        unlink($convert_source);    
    
                    }

    This code to convert avi to mp4
    ffmpeg concole output :

  • FFMPEG does not add images to audio

    20 février 2018, par Googlebot

    I want to create a slideshow with a background music by ffmpeg, and use the command

    ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

    and map.txt is like

    file '1.jpg'
    
duration 15
    
file '2.jpg'
    
duration 60

    The result is a video with the audio and blank background. If I run the above command without audio as

    ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4

    a perfect video of the images (the intended slideshow) is generated (but obviously without audio).

    I reckon the problem is related to synchronising the audio and images.

    This is the terminal output for the first command

    ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

  • ffmpeg screen blending mode makes transparent png pink

    28 janvier 2014, par gilad s

    I have a sequence of PNG files with transparency - I'd like screen-blend them on top of a video

    ffmpeg -i video.mp4 -i "Images/%03d.png" -filter_complex "blend=all_mode='screen':all_opacity=0.7" output.mp4

    the images are indeed merged on top of the video but with a pink overlay ?!

    I also tried to add "-vcodec png" and "-vcodec libx264" and to try a .mov video but got the same result.
