Wondering what additional statistics of a rip people would need when archiving?

Atm i've deduced that this is pretty much what people would need:
Code:
  // Codec and frame
  private String container = "";
  private String codec = "";
  private int width = 0;
  private int height = 0;
  private double aspectRatio = 0.0;
  private String frameType = "";
 
  private int bitrate = 0;
  private double bpp = 0;
  private int frames = 0;
  private double frameRate = 0;
 
  // Advanced Details
  private String cqm = "";
  private boolean packedBitstream = false;
  private boolean qpel = false;
  private boolean bvop = false;
  private boolean nvop = false;
  private boolean ivop = false;
 
  // Set Audio Details 
  private String audioCodec = "";
  private int audioBitrate = 0;
  private String audioAllocation = "";
  private int audioFrequency = 0;
  private int audioChannels = 0;


Anything else?

"audioAllocation" Is that the same as interleave/preload?

If no, I suggest that.

No, that would be CBR or VBR allocation.

Preload is a good one though.

Nice work!
What about some info related to the codec? e.g. for the xvid the percentage of each quantizer used (a-la DRF Analyzer).
and arent audio frames counted separately from video frames and then interleaved one another? iirc i found some avi with a different count of audio and video frames.

Well i'm only using JNative to access mediainfo, and quantizers are very difficult to implement from what i've read. i wouldn't expect their usefulness be great enough to request the feature. Might as well :lol:

The thing is, is DRF average a reliable quantifier of quality anymore?

at the italian forum they all get bitchy if you dont post the drf analyzer output in the thread :lol:

well to think about it, this could be a good reason not to implement it :lol:

ahah... yeah, pissing off the italians is a feature! :lol:

By output, do you mean just the average or all the crap?

This is getting insane ....

How about adding the brand of memory your pc has so we can statistically calculate the quantum probability of corrupted frames ? :wacky:

Or the last measured IQ # of the ripper ?

Speaking as an Italian, pissing one off isn't a feature since it's a fairly easy task :lol:

@rogue, okay i got all that, well not FourCC, but that's not really that useful.
Language you really have to do yourself, ditto subs.

Interleaving i'm having diffulty finding, mediainfo doesn't seem to get that value. Is there a way to calculate it or is it header info?

I wouldn't know, I don't use the export feature. Most of the stuff that doesn't change (like GMC/B-Vob/Qpel) is already in my release templates and the rest I copy/paste. Not very sophisticated, I know. :)

Archiver/movie maneger, you give it a location and it does everything itself the best it can. I really find it retarded how you feed a program a file that's named:
Crappy.Movie.1997.DVDrip.XviD-USB.avi
and it then asks you what movie it is and what the source is? well duh! :lol:

I simply couldn't archive the stuff i had coming in with the amount of markup and processing i had to do to add it to EMM, etc. so i'm far behind adding on my stuff.

So i'm making one that's based around emule (so the hash will be there with the file entry, as well as other useful stuff which i don't have space to mention) and can essentially devlove into drag and drop to archive without any other interaction if you want. Its also based around the concept of the same movie, different editions and different rips of those editions. I've not seen a program that deals with that well yet, they dupe all the info and you get inconsitancies. There's loads of stuff i can say its planned to do, but since it doesn't currently do them, i guess its a bit pointless to mention it.

I started making one last year, but there were a couple of design and time issue problems. I wasn't in the right frame of mind to write a java parser for media, but since then i've used JNative a few times so can use a native library. MediaInfo is quite a mature filespec library, i just request they go a bit further than identifying matrix and state which matrix it is. There's a linux port scheduled soon too. Also thought i might as well swtich the db storage to JDBC so you can use mysql, XML, msaccess, or whatever.

So i was just wondering whats useful to be saved stats wise.

edit: I'd mentioned something before -
http://forum.dead-donkey.com/viewtopic. ... light=java
doesn't look like that anymore

Are you insinuating that I rip crappy movies? :evil:

But really, sounds pretty cool. I don't archive rips (used to, but not anymore) since I don't watch a movie more than once, so I don't have much ideas to share as far as a movie cataloger goes. I even delete my own rips as soon as I see 10-12 full sources :wacky: But let me read that 5 page thread to get a better idea of what you are upto anyway. :wink:

I was trying to think of a generic realistic-sounding hollywood movie. Well you have ripped some crap movies i'm sure, but with fh having soiled itself.

That older thread isn't all that useful anymore (its over a year old), but i got some of the framework down so i've recycled some of the classes

I was just kidding. Having made a dandy rip of the 2005 classic 'The Fog', I can confess to my lack of taste in movies. :lol:
