The information that i have:


The BBC (British Broadcasting Corporation) placed in March its project of codec Dirac video on SourceForge (the famous communal site of development of free software).
It works with this codec since January 2003 and now go to the community of the free software so that it can make a product of it.
The Dirac codec uses the compression by " ondelettes " that consists in decomposing a picture in a sum of waves of different frequencies. In fact, it is the result of the decomposition that is pressed.

The BBC affirms that the codec produces a file 2 times less voluminous than a MPEG2 file high resolution, and that it will be optimized for the streaming. In short, the performances of the codec would be comparable to the one of Microsoft (WMV 9).

Hi,

A little update for the last binaries. Here (http://atlas2.tgv.net/~media-video/forum2/viewtopic.php?p=49202#49202) for the encoder & decoder. If you want test Dirac v3.1.0, don't forget to take the "Make_Header" package too. There is also the FAQ (http://atlas2.tgv.net/~media-video/forum2/download.php?id=1073) taking from the sources.

For more informations about encoding, I've include the Readme in the "Dirac_encoder" & "Dirac_decoder" package.

In addition, there are different video samples (raw RGB) in the official website : http://sourceforge.net/projects/dirac/

Was playing with it last night...Can't get any sort of good quality out of it. And is slow as merry hell, but still it's worth keeping an eye on.

I'm going to try and get them to accept a patch so it compiles in VC6...I can but try :)

is it possible to have a vfw or direct-show version of the codec, to make easier encoding test?

Nic

@gino: I think, in it's current state, it isn't worth the hassle of writing a wrapper for it. It's too slow and the quality too poor. But I'm sure that will change, then writing a dshow/vfw wrapper should be trivial (it has a nice & easy interface :) )

can't encode?

D:\__DIRAC__\exe\dirac_encoder.exe -input "D:\[MANGA]\trigun\TRIGUN-ep01.avi" -output "D:\[MANGA]\trigun\TRIGUN-ep01.avi"

where's the pb??

Good work damrod, :)

If only you explained to me where the problem due to encoding came from. :confused:
I don't manage to find the flaw of the system.
Unless someone succeeds in taking himself of it, I should be interested in knowing the reason and what can i do to remedy.

See you soon

damrod you do realise with that command line you are trying to overwrite the input file with the output file ? since the input file is in use that isnt going to happen. :)

try this instead
D:\__DIRAC__\exe\dirac_encoder.exe -input "D:\[MANGA]\trigun\TRIGUN-ep01.avi" -output "D:\[MANGA]\trigun\TRIGUN-ep01-dirac.avi"

Looking thru the code the commandline parsing does look broken anyway. Just having an input and output file will work, but the other parameters may not be parsed. Easily fixed though (and might already be in your code, as my CVS code is a couple of days old)

damrod

D:\__DIRAC__\exe\dirac_encoder.exe -input "D:\[MANGA]\trigun\TRIGUN-ep01.avi" -output "D:\[MANGA]\trigun\TRIGUN-ep01-2.avi" -SD576 true

doesn't work also....

i upload my last gui if you want to check...it create a .bat file
even if it execute the encoding....

damrod

maybe my source is incorrect....avi/divx


to use the gui... put it simply is the same dir as dirac_encoder.exe...

Now that guliverkli made a dirac DS splitter filter, and the source is already at version 0.4.3 - is there anyone able to provide current builds regularly?

@Ligh: Look at the other thread.

Hello :) ,

One can hope for one functional GUI of the last version (0.4.3) of this encoder.
