What can I do if php cannot execute the exec () function!

What can I do if php cannot execute the exec () function! I used ffmpeg-php extension and needed to execute commands such as exec ("ffmpeg-I 1.amr 1.mp3"). This is to convert the amr format to the MP3 format.

However, the security mode is disabled. The function is also enabled.

Echo'


'.Exe c ('whoam ');

You can run the command to view the server name, but the command is not an external command.

What I use to read a video is:
Extension_loaded ('ffmpeg '); // F: \ mv \ 1.wmv video file path.
$ FfmpegInstance = new ffmpeg_movie ('H: \ ppcall_api \ ps0001.wmv ');

This can be printed, but not converted. Please kindly advise.

Do www-datausers have the execution permission on the files to be processed (ffmpeg,1.amr,1.mp3?

Permission issues: chmod 0775 1.amrand ffmpeg.exe

Perform operations on files to check whether you have operation permissions.

What server? Permission issues, refer to: http://firerain.sinaapp.com/blog/item/5-ffmpeg-mp4

Check whether the absolute path of your file is consistent with the one you spelled out.

Has your problem been solved? I encountered the same problem, but I want to convert the audio. please help me !!!!!!!!!!!!
