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

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

-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


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

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

Don't push it
Screen interface already done



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
If not, it was worth a try
DON'T EXPECT THIS OVERNIGHT, AND NO PROMISES
(I hope Milan shows up, and fixes it, instead of having to make this hack )

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...

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.

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...

That's the spirit guys
@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

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

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...
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?
