Help to convert dvd to printable binary

[Hellohello]

Hi, I'm doing a project and need help to get the code from the dvd (movie) and convert the binary to a printable form. Suggestions are appreciated.

Printable form? You mean extract frames as PNG or JPG images?

[redwudz]

If you mean to print out the binary of the pits and lands on a DVD disc, you better have a lot of paper handy.

Here's a bit of info about CDs that is similar: http://www.laesieworks.com/digicom/Storage_CD.html

Maybe you simply mean the binary of the instruction set in the ifos?

Several programs can decode that for you - pgcedit, dvdremake etc but none have a direct print-out so you would need to do a far amount of copy/pasting.

This wont win the Turner prize you know? 8gb @ 1 page per k = 8,388,608 pages possibly even more, if my maths is wrong.

[Hellohello]

Hi, thanks to everyone for the responses. I apologize for my low literacy in this matter and do appreciate your help.

To clarify, taking your feedback into account:
I want to work with a single frame-grab image from a dvd, and then extract the code so that the binary is printable as numerals.
( I don't want to print 8,388,608 pages! -- but that is awesome information to know, that it translates into so much type info)

If dvdremake allows that, I will have a look.
If another program is suitable please tell me about it.
Cutting and pasting is okay, as long as I can access the binary. Does dvdremake allow cut and paste into word, etc?

Also, I am interested in how to calculate how many pages of binary would result from decoding a 1/2 hour tv show (minus commercials). That's something like twenty minutes of play. RabidDog mentioned "8gb @ 1 page per k = 8,388,608", is 8gb the amount of data for an average length movie?

Best wishes

I must withdraw my earlier comments now as the programs I mention can not do what you require.

I would be surprised if anything can given the compexity of mpeg2 compression etc.

And you could not simply take a screen grab and print that out as the process of creating the image would actually alter the image at binary level.

You might try this: I opened a VOB from a DVD in MPC-HC and paused the video, then used 'File>Save Image' to grab one frame of MPEG-2 video to make a .jpg:




Then I opened the .jpg in Virtual Dub (Or VD Mod) Hex Editor, 'Tools>Hex Editor'. That may not be a true representation of the actual frame data, but it is representative of what a hex editor can do. There are about 14,600 lines of data from that image. If you figure about a two hour video, 7200 seconds X 29.97 frames per second, that would be about 2,157,884 frames of video. Times 14,600 would give you a rough idea of how much data is there, at least looking at it from the hex editor.

This is line 190 (w) converted to binary. (I think. I haven't worked with binary in quite a while. Hex is a lot more convenient for large amounts of data.)
0010 0100 0100 0011 0100 0111 0101 0100 - 0100 0000 0001 0010 01110111 0000 0001 0010

I want to work with a single frame-grab image from a dvd, and then extract the code so that the binary is printable as numerals.

That's still unclear. Do you want YV12 values printed out? RGB? What subsample order? 8 bits of red, 8 bits of green, 8 bits of blue. A line of red bits, a line of green bits, a line of blue bits? An entire plane of red bits, an entire plane of green bits, an entire plane of blue bits? What order? Top left to right, to bottom? Bottom left to right, to top? Formatted in an easy to read manner? Just a huge string of ones and zeros?

A single frame of NTSC DVD is 8,294,400 bits as RGB (720 * 480 * 3 * 8). Printed as ones and zeros with no spaces on 8.5x11 pages, with a moderate sized font will be something like 80 characters per line, 60 lines per page -- about 1728 pages. A half hour TV show would be about 93 million pages (1728 * 30 fps * 60 seconds per minute * 30 minutes).

A starting point would be to open a VOB file in VirtualDubMod then export a frame as a TGA file. VirtualDub's TGA files are uncompressed. TGA files have a 18 byte header at the start. Followed by all the RGB data, top left to right to bottom (or bottom left to right to top), one byte of blue, one byte of green, one byte of red. There are lots of hex dump utilities but I've never seen a binary dump utility. It would be easy to write one.

I don't think the OP necessarily wants a binary (0's and 1's) dump, although it's still not clear what he really wants (or why).

I want to work with a single frame-grab image from a dvd, and then extract the code so that the binary is printable as numerals.

A hex dump still shows the binary data 'as numerals' (and in a quarter of the space of a binary dump).

[Case]

Binary will look something like this anyway. Do you think anyone is able to tell the real thing from a fake random string?

If I was hired to create the program I'd suggest something like this:



Where YYYY is a four digit row number, XXXX is a four digit column number, and the RRRRRRRR, GGGGGGGG, BBBBBBBB are 8 columns of 8 digit binary values of each pixel. That would make it easy to locate any particular pixel.

Or:



where dec is the three digit decimal value of each sub-pixel.

Why am I wasting my time with this?!

Hi to everyone who has replied. This is great help.

In response to Gavino, (" don't think the OP necessarily wants a binary (0's and 1's) dump, although it's still not clear what he really wants (or why).") I do actually want 0's and 1's, and want to represent a glimpse of the enormity of data flying around.

In response to Case, you are right -- most people won't know, but part of the appeal for me is to trace the problem back to the source (sort of, I'm not going to extract raw minerals to build my own computer from scratch!)

Jagabo -- thanks, it's not a waste in as much as you're lending a hand and I appreciate it.

Redwudz -- that is awesome. Now, is the DVD coded in hex, or is that just how the hex editor deals with the data? Binary remains my goal...

A friend has suggested that opening the video in BBEdit Pro to reveal the ASCII code, and then pasting it into an ASCII to Binary converter would work. I just heard this today and haven't had time to wrap my head around it. Any opinions on this?

Thanks for your time!

Now, is the DVD coded in hex, or is that just how the hex editor deals with the data? Binary remains my goal...

Hex, binary, octal, decimal -- are all just ways if displaying numbers. For example the following four representations are all equivalent:

binary: 10100101
octal: 245
hex: A5
decimal: 165
roman: CLXV
upside down apples: QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQ QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQ QQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQQ QQQQQQQQQQQQQQQ

You could just make a random binary stream. It's not like anybody (other than you) would ever know the difference. (Edit: Oops, Case, I guess you already suggested this; I missed it.)

Hellohello, can you explain anything about WHY you want to do this?
