problem with converting 3gp using ffmpeg

[hno]

HI,

I'm using ffmpeg for converting videos in my website but it has problems with converting 3gp videos because after converting to FLV it has 0 size.

I'm using this code for converting videos to FLV:

exec( "ffmpeg.exe -i uploads/$video_name1 -ar 22050 -ab 32 -f flv -s 320×240 uploads/$video_name.flv", $ret );

 

By the way , there is no problem with variables .

 

Thanks

Have you tried echoing out all the variables and attempting to run that command in a command line environment, to make sure that it is not producing any errors? If not do that, but this is really not a PHP issue, unless the paths are messed up. You will probably do better to take it to the ffmpeg people.
