  • A Digital Media Primer for Geeks

    24 septembre 2010, par noreply@blogger.com (John Luther)

    Our friend Monty Montgomery (creator of the Vorbis audio codec used in WebM) has started a video series about digital media. The first episode is an excellent overview of "the technical foundations of modern digital media."

    You can stream WebM versions of the video in your favorite WebM-enabled browser or download it to your desktop and watch it one of many WebM-enabled media players. Supported browsers and players are listed on our site.

  • The FFmpeg-generated video mute after seeking it forward [closed]

    16 septembre 2022, par PersianMan

    The video mutes after seeking it forward. It was created with FFmpeg. When I play it normally (without seeking it), the audio played. I am a Linux user and test it with VLC media player and mpv.

    


    I generated it with this :

    


    ffmpeg  -i video.flv -i audio1.flv -i audio2.flv -i audio3.flv -i audio4.flv -i audio5.flv  -i audio6.flv  -i audio7.flv  -i audio8.flv  \
-filter_complex "\
[0:v]tpad=start_duration=29.429[v];\
[1:a]adelay=3654.0[a1];\
[2:a]adelay=53563.0[a2];\
[3:a]adelay=1148851.0[a3];\
[4:a]adelay=1313774.0[a4];\
[5:a]adelay=1373197.0[a5];\
[6:a]adelay=2061735.0[a6];\
[7:a]adelay=2736617.0[a7];\
[8:a]adelay=3387278.0[a8];\
[a1][a2][a3][a4][a5][a6][a7][a8]amix=inputs=8[a]"\
 -map "[v]"  -map "[a]"  -c:v libx264 -crf 23 -c:a mp3 -s 500x500 -shortest ./output.flv


    


    [1:a] and [5:a] is a main audio (other audio have small duration). If I seek after 1373197.0 ms, the video has been muted (when [5:a] must be played).

    


  • How to batch generate EDL (edit decision list) files for a folder of videos with different run times

    22 janvier, par DnK

    How to batch generate EDL (edit decision list) files for a folder of videos with different run times ? I need to skip exact amount of seconds from the start and another amount of seconds from the end. All the videos have different runtimes I can make EDL files for skipping the intro but need a way to read the video runtime and skip the last 60 or 90 seconds.

    


    This is the format for the EDL I am using with kodi

    


    0:00:00   0:01:20.    3


    


    So if the video is 40 mins 30 seconds the EDL generated skipping 80 seconds from the start and 90 seconds from the end should be

    


    0:00:00   0:01:20.    3
0:39:00   0:40:30.    3
