  • create mp4 video for play online by ffmpeg widthout preload

    14 mai 2014, par Hamid Tanhaei

    i using ffmpeg to create a streamable mp4 video file for play online. but converted video try to load 3 - 4 MB data of video at start. then video can be play and seekable.

    i try to remove start load data by different ffmpeg commands. but each commands had problems.

    my first command(load 3-4 MB data of video at start and seekable) :

    ffmpeg -i file.mkv -movflags faststart -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 1.mp4

    and other commands(removed 3-4 MB load data at start and NOT seekable) :

    ffmpeg -i CloudywithaChanceofMeatballs.mkv -movflags faststart -frag_size 1024 -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 1.mp4

ffmpeg -i DespicableMe2MiniMovie.mkv -movflags faststart -frag_size 10240 -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 2.mp4
    
ffmpeg -i DespicableMe2MiniMovie.mkv -movflags faststart -frag_duration 2000 -s 500x268 -vf "movie=watermark.png [watermark]; [in][watermark] overlay=10:main_h-overlay_h-10 [out]" -b:v 100k -b:a 45k 2.mp4

  • ffmpeg - works through terminal, but not online

    13 mars 2014, par stinkysGTI

    I have installed ffmpeg onto the server using the terminal. All I need it for is to generate a thumbnail when someone uploads a video. I tested the command in Terminal, and it works great. However, when I post it to the site, nothing happens. No errors and no thumbnails are generated.

    Does anybody know why this is ? I read something about the server is running as a different user than what I log in with. I don't really understand that though, and there was no information on how to gain the proper permissions or switch to a user that has the permissions already. All I found was how to show the current user and list all users through SSH.

    When I try and do anything in Terminal using usermod, I get the following error :

    -bash: usermod: command not found

    So can I modify permissions for a user, or change the user that it's using somehow ?
