Thanks Bruce! Your code has been committed and released!

Too soon Andrew... I just found another bug, some blurays don't have any title info at all, and this code simply fails. Though the old code would have as well... I'll take a closer look.

[waltonb]

Well, I finally found some time to work on this... Andrew, could you
please review? I figured out a way to extract title info and continue
if none is found. It seems to be much more robust than the previous
code, actually is able to continue without errors due to disk info
parsing. I've tried this with several disks... it now gets the title
info in a slightly different manner which seems to be more common than
the way the old code as doing it.

Just substitute this code into docd_helper_BD.php in the obvious
place.

regards -bruce.

// Get device name

$cddevice=exec("/opt/vortexbox/get-cddevice");
echo "Using device $cddevice\n";

// time how long it takes to rip movie
$start_time = getdate();

echo "Reading Blu-ray track info. This may take a while...\n";
// extract title and chapter info from the blu-ray.
exec("/usr/bin/makemkvcon info dev:".$cddevice." -r > /tmp/docd_helper.tmp");

$track_info = file("/tmp/docd_helper.tmp");
$length = 0;

for ($i = 0; $i < count($track_info); ++$i) {
  // find title
  $parts = preg_match("/^CINFO:30,0,\"(.*)\"/", $track_info[$i], $t);
  if ($parts != 0) {
    echo "Got Title: $t[1]\n";
    $movie_title = $t[1];
    continue;
  }
  // find longest track
  $parts = preg_match("/^TINFO:(\d+),30,0,\".*\s,\s(.*)\s(\S+)\"/", $track_info[$i], $t);
  if ($parts != 0) {
    if ($t[3] == "MB") {
      // only consider tracks >1GB
      echo "Track $t[1] has $t[2] units of $t[3]... skipping.\n";
    } else {
      echo "Track $t[1] has $t[2] units of $t[3]\n";
      if ($t[2] > $length) {
	$length = $t[2];
	$long_track = $t[1];
      }
    }
  }
}

// Rip the Blu-ray!

[andrew]

Thanks but I think it still needs some work. What happens if $parts = 0? $long_track and $movie_title are never set to anything.

-Andrew

[waltonb]

Yes, you're right. That wasn't one of my test cases.

It should drop down to setting "UnknownTitle" if it can't find the
title, and "0" if it can't determine the longest track. If the latter
happens, the blu-ray is probably somewhat nonstandard from what I can
tell so far.

I'll fix it later tonight after I'm home. Thanks for checking it.

Do you know of any documentation discussing the output of makemkv
"info" mode? I'm just making assumptions about the data contained
there.

-bruce.

[andrew]

MakeMKV is a little light on documentation. I figured out most of it by trial and error. This is whats available

http://www.makemkv.com/developers/usage.txt

[waltonb]

Thanks.. but it's not much help, it refers you to the source code
which is no longer public.

For the time being I simply assigned default values so they're defined
by the time we run the rip command.

We'll need to revisit this at some point to make it work in ripping
multiple tracks on a bluray disc, e.g. a TV series or whatever. When
I get my hands on such a disc I'll come back to to this.

-bruce.

// extract title and chapter info from the blu-ray.
exec("/usr/bin/makemkvcon info dev:".$cddevice." -r > /tmp/docd_helper.tmp");
$track_info = file("/tmp/docd_helper.tmp");

// defaults in case we can't parse info data
$movie_title = "Unknown_Title";
$long_track = 0;
$length = 0;

for ($i = 0; $i < count($track_info); ++$i) {
  // find title
  $parts = preg_match("/^CINFO:30,0,\"(.*)\"/", $track_info[$i], $t);
  if ($parts != 0) {
    echo "Got Title: $t[1]\n";
    $movie_title = $t[1];
    continue;
  }
  // find longest track

      if ($t[2] > $length) {
	$length = $t[2];
	$long_track = $t[1];
      }
    }
  }
}

// Rip the Blu-ray!

echo "\nRipping ".$movie_title." (track ".$long_track.")\n\n";

How to Handbrake watchfolder to run on a powerfull vortexbox server? I want to guet compact files from the DVD/BD disks. Just insert the dvd and forget, cover art and a small mkv file will appear under the dnla server...

Any idea?

pmendes, This has nothing to do with the original thread. You may want to make a new thread and ask your question more clearly.
