IOhannes,

I read on the list that you would be willing to help people with crash problems in GEM on windows XP and 2000. I will explain first my problem. As if you can help with a few of them I would be very grateful.

let's have a look, but in general it is better to ask at the list. the more people read it, the more can help and profit from it.... (so i re-direct this to the list)

I was running pdextended 0.38.4 and most things were running fine. I had problems in one particular patch. To store a large number of images in pix_buffer I figured pix_yuv would solve the problem as RGBA was too large and would cause a crash after a certain amount. Pix_yuv then leaves lots of blue and red dots throughout any image or pix_video. Might you know the problem here?

seems like you are getting into a saturation problem with the rgba->yuv (and/or vice-versa) problem. does the problem occur with special brightnesses only? and make sure that your yuv-image has an even width.

it could also be a problem with SIMD code. you could try using [pix_yuv] and [pix_rgba] explicitely and send them a [simd 0( message.

apart from that, i have been using [pix_buffer] with 3GB of yuv-images on linux without weird colors.

After posting to the list I was advised to upgrade to the newer version. I can not even open pix_video in this as it immediately crashes. I would be happier using the latest version of pdextended and so if you have any advice that would be great.

which version of Gem is this? (i don't use pd-extended and i don't use w32, so i don't know) which version of DirectX? which version of w32? which camera?

what is "immediately"? creating the [pix_video] object? turning on rendering with [pix_video] created? sending "open" to [pix_video]???

could you try the latest available version (e.g. test-version) of Gem for w32 from http://gem.iem.at? (just replace the Gem.dll in your current installation; probably back-up the old Gem.dll before you do so)

Also after updating , including the registry, only GEM and xsample will load. On 0.38.4 only GEM, xsample and pmpd would load. I would love to use all the externals. Maybe this is something for Hans but I thought I'd ask while at it.

afaik, you should wipe the registry before doing an upgrade. but it is really a question for the pd-extended gang.
