Hi List,
i wonder why i get these strange colors when using pix_record with GEM ver: 0.92.2 compiled: Jan 20 2010 on OS X 10.6.3 Any Ideas?
this is grayscale in GEM but instead it is quite blue in the recorded quicktime.
Can someone confirm this (for other operating systems) so i can file a bug report on that? m.

you can file a bug report even if it only happens on a single operating system. the recording code is highly platform specific (that is: the recording backends are platform specific), so it might well be that there is a bug on one system not showing up on others.

The Quicktime code being used in recent GEM builds is not the code I wrote, and does not work that well. Can you try pix_recordQT and see if that loads?

hi max in your patch you use the jpeg codec for recording in this mode you can change the colourmode to YUV with pix_yuv before pix_record. the bug affects only the rgba mode - but when you use a codec without alpha channel this is a easy workaround. this was discussed in the list 2008: http://lists.puredata.info/pipermail/pd-list/2008-03/060168.html matthias Am 03.04.2010 um 00:52 schrieb Max:

Setting the quality for Photo-JPEG to 100% changes it from YUV to lossless ARGB compression. You can keep the alpha and avoid colorspace conversion. Use the 'dialog' message to do this.

wow - dialog, select "Photo - JPEG", click on options -freezes the dialog. also: changing the compression closes the gemwin

but Photo-JPEG has no alpha channel - don't get it.
the point is that pix_record when it´s feed with rgba output a video where the channels are swap feed with yuv the colors are ok doesn´t matter in which mode the codec record the video

also on my machine mac osx 10.6.2 GEM: ver: 0.92.2 compiled: Dec 17 2009 Gem stop rendering confirm the dialog to pix_record after start rendering again 2 sec later it stop again then start again it´s ok and use the changes of the dialog

At 100% 'quality' it does have an alpha. Supposedly it is part of the JPEG spec, but I haven't seen anyone other than Apple use it. It is kind of like having a TIFF with run-length JPEG compression.

The dialog always stopped rendering because the event loop waits for the dialog to close. You will notice that GEM creates a 'pd' app in the Dock in order to do things like window management. Command line apps in OSX cannot just open windows without being a GUI app. It is a hack.
Apple broke the event handling code used in GEM in 10.5. There is no fix other than 'write a full Cocoa app'.
