Automatic encoder selection failed for output stream #0:0. Default encoder for format ogg (codec theora) is probably disabled. Please choose an encoder manually.

Recording audio with FFMPEG works in terminal but not through exec() of PHP
8 août 2013, par lucasalmeida92I 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/video0And 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/*
