Video Scaling not working

Hi! ^^

I've been using PMS since sometime about December. 720p works flawlessly with these;

i7 2670qm, 2,2ghz
8gb ram
GTX 570M, 1,5GB

100/10 connection, wired of course. Xbox 360

Is the above good enough for transcoding MKV 1080p files with softsubs? If yes; they stutter like crazy and are unplayable.
Putting that aside, I tried using the video scaling option, but "downscaling" it instead. 1280x720, that is.
That worked fine, no lag and plays like it should. However, the latest versions of PMS does not properly do this, for me, the same goes for UMS.
It just says: "Setting video resolution to: 0x0, your Video Scaler setting"
I assume the 0x0 means that it doesn't do anything at all since it still lags.

PMS version 1.40 is the latest version that the video scaling option properly works. I would've used that and just shut up, but the image quality is notably worse, being a bit "blurry" so to say..

The guys over at PMS forums doesn't seem to have any solution to this other than me to quit with 1080 files since the xbox 360 doesn't support them.. anymore, so image improvement is non existent, according to one dude over there. However, the reason for me trying to transcode these files is because some series I'm watching doesn't have 720p versions.. Or they are just not seeded anymore *grin*

Phew, I'm sorry for the long post. Anyways, I would like to ask you to check this out, the Video Scaling thingy and make it work, unless you can come up with a solution for transcoding without using this feature.

Thanks in advance, any help would be greatly appreciated.

What Conf file is your renderer using?

Because in the XBOX360.conf file is says this:

Code: Select all

# Max Width and Height supported by the media renderer (0=unlimited) 
MaxVideoWidth=0
MaxVideoHeight=0

Um.. how do I check that? ;o
UMS recognizes the Xbox 360, so I assume it uses the xbox360.conf file..

Also, thanks for the quick reply.

So in:

Code: Select all

C:\Program Files\Universal Media Server\renderers
you should see the xbox360.conf file.

in the conf file it even says this:

Code: Select all

hmm that FLAC might be a problem...

not to sure..

SubJunk might know... or another Dev.

Regardless any PROGRAM edits you make get over written by a CONF file. =)

At least that's how i am to understand those CONF files.

Cause like ok you make a Course change in the application..Normally changes like Static IP, or if you know your hardware limitations you can set Buffering limits... but the CONF file is Granular changes specific to the device receiving the file because in the CONF file there is a Message header that determines the Device to CONF file.

of course... i could be wrong.. lol

But this is why i make CONF file changes and not over all system changes..

TBH dial in your system settings first (the default setup is fine really....) to find what the limits of your hardware is.. then do tweekings of CONF Files.
