Re: [PD] strange colors with pix_record
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?

Re: [PD] strange colors with pix_record
yes the RGBA channels are set wrong on mac osx. the cube appears blue because the alpha channel is read as blue. when you change channels like this R –> G G –> R B –> A A –> B the movie will justified. but it´s not handy to give each record this process so i fixed this with a change in the code of recordQT.cpp in line 241 - instead of colorspace = k32BGRAPixelFormat; i use colorspace = k32ARGBPixelFormat; but i don´t know how this affects other os also the recorded mov is upside down - this can fix in quicktime pro with a click in the properties of the video track - so i don´t looked for the code issue. matthias Am 02.04.2010 um 03:33 schrieb Mathieu Bouchard: > > Johannes a écrit : > >> you can file a bug report even if it only happens on a single operating >> system. > > I think Max implied that he wanted to submit a report as complete as possible > up front. > >> 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. > > Yes, therefore it would also be a good idea to have a screenshot, especially > one containing a correct picture and the equivalent broken picture side to > side.

Re: [PD] strange colors with pix_record
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: > that version of GEM > GEM: ver: 0.92.2 > GEM: compiled: Jan 20 2010 > unfortunately doesn't have a pix_recordQT > pix_recordQT > ... couldn't create > > m. > > Am 01.04.2010 um 21:25 schrieb chris clepper: > >> The Quicktime code being used in recent GEM builds is not the code I wrote, >> and does not work that well.

Re: [PD] strange colors with pix_record
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.

Supposedly it is part of the JPEG spec, but I haven't seen anyone other than Apple use it.

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'. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Re: [PD] strange colors with pix_record
If I get some time this week I can work on getting the correct code back into pix_record. The problem you have was fixed about 4 years ago, but I don't know why pix_record/film/video use really old code now.
