  • 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 ?

  • Recording audio with FFMPEG works in terminal but not through exec() of PHP

    8 août 2013, par lucasalmeida92

    I use this command to RECORD audio and video from my webcam in terminal and it works !

    ffmpeg -f video4linux2 -r 25 -sameq -s 640x480 -i /dev/video0 -f alsa -i plughw:0,0 -ar 22050 -ab 128k -y webcam.flv

    But when I do it through PHP, like this :

    echo shell_exec('ffmpeg -f video4linux2 -r 25 -sameq -s 640x480 -i /dev/video0 -f alsa -i plughw:0,0 -ar 22050 -ab 128k -y webcam.flv 2>&1 &') ;

    I receive that log :

    Before I got that Mic device problem I was having problem with the Webcam device's permissions, then i did :

        sudo chmod -R 777 /dev/video0

    And the video capture was ready to be used ! But now I got this Mic device problem !

    I think it can be about permissions too, but I dont know linux very well and have no idea how to fix that !

    Thanks !

    I just found the solution ! =x

    sudo chmod -R 666 /dev/snd/*
