DVD2AVI Performance

[hrg27]

Hi

I have a question about the time required to use DVD2AVI for a specific DVD.
As you may know, DoItFast4U or CladDVDXP has embeded DVD2AVI in their program, so after the ripping it generates the necessary d2v files.
As to my surprise when I use those application it takes DVD2AVI about 15-30 minutes for different DVDs to get the job done. BUT... when I want to do it by myself (not using through above mentioned applications) it takes about 2 hours to do that.
I am almost sure that the settings I am using is the same as those software.
Does anyone have any ideas ?

Thanks

Most likely you are manually using the "Save AVI" option. With DoItFast4U you "Save Project"s. Very different things...

...but most likely you are downsampling to 44.1 inside DVD2AVI? That is *MUCH* slower than to do this externally with besweet (ssrc).

Just for fun ;)

this is a pre-release crippled version of my re-write of dvd2avi you cant do any saving with it on purpose, but you can create d2v files.

Could you check how fast it is ? ;)

(I must get round to releasing the full version one of these days ;) )

Nic, haven't looked at it yet, will definitely do.

But since you are rewriting DVD2AVI, could you please check how your code handles the following GOP sequence in an PAL MPEG2 stream when creating the d2v:


IBBPBBPBBPBB
I
IBBPBBPBBPBB


DVD2AVI 1.76 writes it to the d2v like this:


2 2 2 2 2 2 2 2 2 2
2 2 2
2 2 2 2 2 2 2 2 2 2 2 2


which I think is not correct. Look at http://forum.doom9.org/showthread.php?s=&threadid=44150 if you need more information. Thanks.

OK, checked your release and it does the same thing (as well as MPEGDecoder.dll, BTW). Grr. Now is that a bug in DVD2AVI?
