I'm building a script that executes ffmpeg. I use the system() code which executes the command properly, however it does not return a value.

I attribute this to being the fact that the ffmpeg command has a dymanic output that shows the conversion progress and then gives a result.

I'd like to be able to pull that dynamic content into a variable if possible. Is there a way?

In this case, I cannot run ffmpeg-php on this server (I don't have admin rights, nor can I get them)

Thanks.

    If you need to execute a command and have all the data from the command passed directly back without any interference, use the passthru() function.

    that or redirect the output to a file and read it on completion

      I tried both ways and I'm still not getting output (although the script is running properly)

      I tried

      $result = passthru('ffmpeg -i test.mov Test2.flv', $retval);

      as well as

      $result = passthru('ffmpeg -i test.mov Test2.flv > output.txt', $retval);

      The output.txt was created, but it was empty.

        what does it return when done on the command line?

          Starting at the "Press [q] to stop encoding" is when the output becomes dynamic. It updates the status as it works its way through the file. Once that's done the last line of the code is outputted.

            $result = passthru('dir', $retval);
echo $retval;

            does that produce anything?

              TestGetDir.php useraccess 0

              Yup, outputs correctly.
