most pixels ever issue - Unable to access jarfile mpeServer.jar

in Contributed Library Questions • 2 years ago

Hi,

I am sorry to say that I have a fairly limited understanding of processing and coding (but am trying to learn).

I am trying to use the mostpixelsever library by Daniel Shiffman.

The tutorial at the url below states that you should enter the terminal code below into terminal.

https://github.com/shiffman/Most-Pixels-Ever/wiki/Processing-Tutorial

java -jar mpeServer.jar -debug1 -framerate30 -screens2

However, I get the following error:

Unable to access jarfile mpeServer.jar

I have tried googling this in all sorts of combinations of search terms but all I got was the possibility that I am not referencing where the mpeServer.jar file is on my computer properly (using a Macbookpro).

The processing sketch told me I had to change my java to 1.6, so I did this.

But now there is a processing sketch error (I am assuming it's because of the terminal issue?):

Client: Settings: server = localhost:9002, id = 0, local dimensions = 200, 400, location = 0, 0

I am just trying to run the example sketch that comes with the library.

Does anybody have any ideas?

Thank you so much in advance.

" where the mpeServer.jar file is on my computer properly" " I am just trying to run the example sketch that comes with the library."
I suppose this file is shipped with the library you installed. If not, you need to download it, probably at the place you got the library.
And when running the command line, you have to be in the same directory as this jar, or to supply the path to it.

Hi Phi.lho,

Thank you so so much for getting back to me! It seemed to be a silly query as in fact it was just a case of putting the mpeServer.jar file at the root of my mac directories. i.e. in the same level as 'desktop,' 'documents' etc - in case anyone else has this issue at all.

Thank you again for your help!!

The server works now, however the sketch is not showing anything (but I guess this is a different issue that I will try and solve first).

Thank you again - saviour!!!

Jamie
