2.08b auto-resolution func. different than 2.07b?

[Spreeni]

Hi,
I've noticed a different behavior of the auto-resolution function in 2.08 beta. For example, a 55 min. mpeg-PAL-file ist reduced to 592x448 at 700 MB size. With output size is set to 800 MB the resolution is reduced to 560x416. This is strange, because the resolution should be higher at a higher bitrate. This happens in compatibility-mode with both, MTK/Sigma and ESS chipsets.
The 2.07b-version (with ESS-Support) choose the 560x416 resolution for an 700MB file and rises it up the higher the output size is set.

Here are parts of the log-files: AGK @ 700 MB and 800 MB output size

After a few more tests I only noticed this behavior by using the xvid-codec (the modified one coming with the 2.08b update). Although it made no difference using or not using the new compatibility option. I think the reason for the strange resolution-behavior could be the modified xvid-codec of the 2.08b package. What do you think?

[woah!]

i have gone back to 2.07b because it gave me perfect DXN avi's that played great on my rjtech800. but with the MTK option on in the 2.08b version, it gives me blocky playback on the standalone? it seems to be using a custom matrix, which i dont think is right either, but i cant fiqure it out so i have gone back to 2.07 and no issues with the same encode.

heres the info on both encodes:

ESS option ON

Packed bitstream: No
QPel: No

Max consecutive B-VOPs: 1


blocky playback.

===============================================

MTK option ON

blocky playback.

===============================================


2.07b with the DXN xvid codec version


Packed bitstream: Yes
QPel: No

Interlaced: No
Aspect ratio: Square pixels
Quant type: H.263

I-VOPs: 28 (1.87%)

S-VOPs: 0 (0.00%)
N-VOPs: 0 (0.00%)

Max consecutive B-VOPs: 1


this one works perfect on my standalone.

===============================================

the xvid codec i use is the one that gives a tick option for "Strict conformance to DXN profile standard" and gives a XviD0038 code in Mpeg4 modifier.

http://server3.uploadit.org/files/bubbaray-dxn.jpg

i am gonna stick with the above setup i think as i have had no issues with any encodes since using it.

[Spreeni]

Oh, I didn't know that I can configure the codec myself, I thought autogk uses its own xvid-options and overwrites custom configs. This will be a playground for more tests, thank you for that information. By the way, wich xvid-version do you use? I can't find this "strict conformance to..." option in my 1.1 beta 2.

Hello Spreeni,
I suppose you still can't configure the codec
Since including the xvid 1.1, AGK uses the "unrestricted" profile unless you activate one of the two SAP options:
either ess --> DXN HT profile
or mtk --> MTK profile
If AGK has changed it's behaviour pls let us know :)

Concerning the "strict conformance to" it seems not to be the standard GUI for the encoder ...

i got this xvid pack from a thread here a while back,and i cant remember which. it was to do with the DXN compatability and someone posted a link to this modified version and i have had great success with it since then on my rjtech800 which uses a MTK1389 chipset.

i can upload the xvid.inf/xvidcore.dll/xvidvfw.dll files so you can have a look at them and maybe figure out who made it as i cant now.


this pack doesnt work with 2.08b as the settings are over-riden but not with 2.07b

files are below:

Read the changelog of 2.08 beta....
new XviD VFW dll packaged for MTK/Sigma chipset support (use only bundled version of XviD to be able to use that option)

[woah!]

i did and the results above are from using that version.

i had to go back to the version above along with 2.07b to get back to having working standalone avi's.

with the packed version codec and 2.08b i get blocky playback (very small squares) and with 2.07b and my xvid version above with the same encode no blocks.

its probably a problem my end, but if it works with 2.07 i will just stick with it and be happy :)

Hi,

Just a few lines concerning auto-resolution, I tested same source with clean AGK 2.08 install: size 560*304, predicted 58.99; no MTK or ESS.
Changed AGK 2.08 to 2.07 (just the prog, not the install) same results: 560*304, predicted 59.00, first pass 62.19
The resolution problem could probably be narrowed to the ESS or MTK options ...

Did
