Here is one way to get the size and bitrate of a video using ffmpeg:
#!/usr/bin/perl -w use strict; use warnings; my $file = $ARGV[0]; die "usage: arg1 must be a video file\n" unless $file; sub trim { my $string = shift; $string =~ s/^\s+//; $string =~ s/\s+$//; return $string; } open (FILE, "ffmpeg -i \"$file\" 2>&1 |"); while (<FILE>) { my $line = $_; next unless ($line =~ m/^\s+Stream #.+?: Video/); my @pieces = split (',', $line); my @vsize = split (' ', trim ($pieces[2])); my @vbits = split (' ', trim ($pieces[3])); my $video_size = trim (shift @vsize); my $video_bits = trim (shift @vbits); print "$video_size $video_bits\n"; last; }

Example usage:
./ +er-480p.mp4

Output: 854x480 537
