Hya,
Go for it Kwag :lol:
And if it's not asking too much could you build it with bitrate constraint routines :?: :twisted:
Cheers buddy

So if anyone wants to patch a VBV buffer size, have fun :roll:

Edit: I can see the writing on the wall: "kwag, can you write a VBVPatcher program" :lol:

-kwag

So you say the same as me (AFI understand). At begin of GOP :?: So, if it is possible to know where GOP start (AFAIR ReStreem knows ;) ), aplication that changes VBV value would be possible to create. Where are you vHelp :twisted:


EDIT: And I see now that this is possible.
[Crazy enought programer wanted] :lol:

I even think that the GOP header is (more or less) 2416 bytes long.

Hi Marcellus,
I still can't see your screenshots.
I only see tripod's logo.
Damn thing it uses the registry instead of ini file or something.
Can you check your settings at tripod again?
Thanks

kwag 02-25-2004 06:58 PM

Don't push it :twisted:
Screen interface already done ;)

http://www.digitalfaq.com/archives/i...2004/02/36.jpg

Now I'll go read more on the MPEG-2 stream, so I can search every sequence header for the VBV offset, and patch it.
I hope this works :roll:
If not, it was worth a try ;)
DON'T EXPECT THIS OVERNIGHT, AND NO PROMISES :!: :rotf:
(I hope Milan shows up, and fixes it, instead of having to make this hack :roll: )

Hydeus 02-25-2004 07:02 PM

Another brainstorm, and we all have that big impossible to resolve thing resolved by aplication egzisted from years (ok seconds ;) ) :D Do we have to make everything this way :evil:

I want my credits in this :!: :hammer: :bugeyes:

@Kwag
Have you contacted Milan:?: I have no response (send 22:30 today).

You probably knows header lenght, but if not (I dont know either) your "red_planet_extreme.m1v" (I think it is still broadcasted by u) have very specyfic header consist of some ....R...JR".)H...". period, and not only this. Very beautiful, you must se this :lol:


I now go to sleep. God night to all, exept Kwag, you must finish this task :crashed: :expert: and after that you can :playball: a while :rotf:

rds_correia, your awesome!!
Thanks for smoothing things over....

poerschr 02-26-2004 01:25 AM

I was just thinking about the very best program/movie to do tests on --- I can think of nothing better than the first episode of Blue Planet - Has anyone seen this program???

It has wealth of great scenes to test: 1) highly complex moving fish to test motion estimation, 2) underwater gradients, 3) slow moving pans of large whales (even slow motion photography). In my opinion, this puppy has everything...

Sorry guys...

I've ben very busy w/ my GUI app :roll: and haven't had the time to read
up on all the threads - just random checkings.

It's late and my :roll: are beginning to pop out.

Slow down marcellus. I did not discourage anybody. I think you're again the only one to feel offended by this.
Hydeus did not take that personally as you did. :wink:

Hydeus 02-26-2004 07:53 AM

I didn't take this personaly , cause I knew that I was right. And when Kwag will build this program (as far as he will buid it) it will be ...

And that's the way it should be. Sometimes you're right, sometimes you're not. Good luck kwag, and thanks for that idea hydeus... :mrgreen:

marcellus 02-26-2004 10:32 AM

Well, I didn't take anything personal either :D
Hope the same about you :wink:
Just a thought that passed through my mind, nothing more...

rds_correia 02-26-2004 01:37 PM

:D That's the spirit guys :D
@Marcellus,
I don't know if I'll have enough time before the weekend but I really would like to try your ffvfw settings.
Any luck on the hosting yet?
Cheers

kwag 02-26-2004 01:46 PM

As promised, here's version 0.1 ;)

http://www.kvcd.net/VBVPatcher-0.1.exe

Notes:

It only patches the FIRST sequence header, so the rest of the file is still unpatched.
PLEASE, i've tried to do my best, and force to open only a .m2v file, and even if you rename a file that is not a Video Elementary Stream to a .m2v, I check the header and display that it's not a .m2v file.
This is to offer protection, and you don't screw up a file that is not a .m2v video stream :cool:

Please test it, by creating some mpegs with ffvfw, and then patching it.
After you drag the mpeg file to Bitrate Viewer, you'll see thah the VBV is 112.

Next version will enable to select different VBV values, and will patch the complete file.

But first, let's play with this for a little bit, ok! :)

I begin to be embarassed by this stuff. When I open the thread I have no problem seeing the pictures. How is this possible, that I can see them and you don't? I am a newbie in the free hosting matter, I never used such thing in such way before signing-in here. I could use an advice since I'm stuck here, I really don't know what could I do further, I don't know what settings I could change at tripod and where... :oops:
Could you think to another solution?
marcellus

EDIT: I tried to see the thread thru www.anonymization.net and even so I can see the pictures. What this could mean?
