I have a very fast network, but a slow media server.

Is there anyway of turning of CPU-hungry activity (like image scaling), on the basis that it is quicker to transfer 5Mb over the network, than to scale the image down on a 600MHz processor?

Hi,

Yes, there is a way to disable rescaling of photos if you are comfortable with editing the server's .ini file.
You can find this in the installation directory of your Twonky server on Linux.
- Open the file
- add in the following line
norescale=1
- save and close the file, then restart the server
This should be enough to disable picture scaling.

If you ever want to turn the picture scaling back on, just repeat the process and change the value to
norescale=0

Hope this helps!

Excellent, thankyou for your help.

Is there some documentation of settings I can use here?

Hello,

I have recently attempted to turn off scaling as you describe via the configuration file and with the web interface as follows:

http://[twonky IP]:9000/rpc/set_option?norescale=1

The configuration file gets rewritten, and the RPC on the web interface returns "PROPERTY NOT FOUND!"

I am running version 5.1 on a Western Digital MyBook World Edition II. Is that property still supported in 5.1? If not, how can I disable image scaling? It is killing the puny processor in this box...

Thank you!

Might it just have returned that message because that property wasn't there before you wrote it?

Try http://[twonky IP]:9000/rpc/get_option?norescale to see if the property has been written.

Hi PB,

Yes, it appears that property isn't there (same message with get_option). The question is, how do I add it? According to the original post, I should be able to add it to the config file. When I add it to the ini file, the server overwrites whatever changes I make on restart and norescale disappears. Any ideas?

Thanks,
Eric

Maybe the property just isn't used by 5.1 - I tried it with 4.4.18.

If you put the norescale property into the default ini file that comes with Twonky and then re-install Twonky it should use the settings in the default ini as the basis for its initial config file. Might work.

I found a solution for the PS3. Find clients.db (/twonky/resources for me) and add the following line to the entry with the PS3:

XM:NOTRPICS

This will send the full resolution image to the PS3 only. You'll have to configure other receivers independently.

Do EXIF tags work for others when viewing photos on the PS3? Pretty much garbage on my PS3. Do anyone know how to fix that?

This seems to be a common problem, and one where I think that one size does not fit all.

Some Twonkymedia installations are low power but on fast networks, so are better sending the full image (my network setup falls into this bag), others are on slow Wifi networks with fast processors, so are better of rescalling!

Clearly what works for one is bad for the other, there is no comfortable medium.

Editing the clients.db is only a temporary solution, and it gets updated every release, and means end users have to hack it each time. It's almost like there needs to be a global setting that determines what class of server each server falls into and sets the rescalling appropiately...
