Hi all,<div><br></div><div>I managed to compile gem with gmerlin and now it reads my MPNG film well, however, it still does not render with a transparent background.  I have a series of png images which have the background removed in places so that whatever is underneath shows through.  I&#39;ve converted them to an mpng .avi using</div>
<div><br></div><div>ffmpeg -i man%04d.png -vcodec copy reflect1.avi</div><div><br></div><div>If I do the reverse, </div><div><br></div><div>ffmpeg -i reflect1.avi -vcodec copy reflect-alpha%04d.png</div><div><br></div><div>
Then the resulting images maintain the transparent background, so I know the conversion process is working properly.</div><div><br></div><div>Now, when I import this film using pix_film, I just can&#39;t seem to make it overlay the way I want it to.  The (transparent) background does not appear transparent.</div>
<div><br></div><div>If I replace pix_film with pix_image and the original .png images in my patch then everything works the way it should.</div><div><br></div><div>The reason I&#39;m trying to use videos is that I have thousands of images (most don&#39;t need to be transparent) and it loads images/draws faster than pix_image and pix_multiimage tries to load everything into memory at once (kills my laptop around 50 images) and atm I&#39;m too lazy to figure out a buffering system.</div>
<div><br></div><div>Can anyone suggest an alpha-enabled codec that might work properly with Gem?  Am I missing an object somewhere?  Is there a good non-video way to do this?  Has someone already made VJ mixing patches that might help me?</div>
<div><br></div><div>Thanks,</div><div><br></div><div>-martin</div><div><br></div><div><br></div>
