Hi, This is also related to the thread: "GEM: where to find gem-CVS20060412-NT-i686-bin (windows binaries)"

I have DirectX 9.0c and QuickTime 7.4.5 installed in my Windows XP machine. I attach a modified version of the help-patch of pix_film: the only change I've made is to add "RGBA 1" arguments to the [open...( message fed into the pix_film. The important part is the "1" argument, which forces pix_film to use QuickTime rather than DirectX. Now, try it with a dv-pal AVI file with audio - or maybe with ANY avi file with audio - or maybe even with a mov (I reproduced it with a dv-pal avi). The annoying thing is that it is playing the file audio track, and it does not come from PD (dsp is turned off). I dunnow where the heck the audio comes from but i hear it. If you don't activate the "auto" check nor move the frame number, a 1-frame-long (which is 40msec) fragment of audio is repeated over and over again, and the patch consumes almost 100% CPU. With old gem-CVS20060412-NT-i686 this doesn't happen, with the same version of quicktime. GEM only reproduced the video, through QuickTime, and ignores the audio (which is what you expect from GEM isn't it). Also, if you don't activate "auto" nor move the frame number, it consumes much less CPU (which is reasonable cause it's not decoding new frames). I guess I do can assume that 2006 version is also using quicktime because of the "1" argument in the open message. I don't know if the attached output (obtained with old 2006 version) (at the end of the message)confirms this. Why and where is the audio being played? How can I turn it off and avoid useless cpu usage??? Thanks bye m.
