Is there a way to check if a shell command is still being processed?

[LanceT]

I want to get a simple true/false to check if my ffmpeg is still converting a video. You can check out the shell command I executed below.

 

convertToFlv( $input, $output );

function convertToFlv( $input, $output ) {

echo "Converting $input to $output";

$command = "ffmpeg -y -i $input -acodec libfaac -ar 44100 -ab 96k -vcodec libx264 -level 41 -crf 20 -bufsize 20000k -maxrate 25000k -g 250 -r 20 -s 640x480 -coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -flags2 +brdo+dct8x8+bpyramid -me umh -subq 7 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -rc_eq 'blurCplx^(1-qComp)' -bf 16 -b_strategy 1 -bidir_refine 1 -refs 6 -deblockalpha 0 -deblockbeta 0 $output";

shell_exec( $command );

}

 

Can someone provide me some code that will help me check if ffmpeg is still doing the conversion?

Well, it should just keep moving through the code, so you could echo out some AJAX loader, run shell_exec, and in the line right after shell_exec do whatever.

 

And so you know, shell_exec outputs the return from the command.

It will be if the user loaded another page and wants to check if his video is done converting. So it won't be on the same page as the code above.

 

Anyone have any ideas?
