Help with run command from the shell

It was suggested that I add a ‘report’ parameter to the ffmpeg code(in the php file), after revising with the ‘scale2ref’ code which appears to prevent the video from uploading/proceeding:

$ffmpegCommand =”.$ffmpeg_b.’ -y -i ‘.$video_file_full_path.’ -i ‘.$watermark_image_full_path.’ -filter_complex “[0]scale=426:-2[vid];[1][vid]scale2ref=’oh*mdar’:’ih/10′[wm][vid];[vid][wm]overlay=5:5:format=rgb,format=yuv420p” -vcodec libx264 -preset ‘.$pt->config->convert_speed.’ -crf 26 -report’.$video_output_full_path_240.’ 2>&1′;
$shell = shell_exec($ffmpegCommand);

I couldn’t see where the -report parameter was supposed to output (error.log has a filesize of 0). So I was asked to “run command from the shell and check”?

But, I’m not sure what command and where/how to do that.

I tried adding this to the php code, and attempted to upload again, same result

echo shell_exec(“/usr/local/bin/ffmpeg -report log.txt 2>&1”);

any additional help is appreciated

Also in #PHP _↴
