Hey all,

Attached is an example patch of a bug I found with chris's current gem compile (march 16th).

If you create a window with FSAA 8, with no gemheads in it, or with only gemheads that are not processing the window does not seem to start rendering, and apears currupted. Without FSAA 8 the window behaves as normal.

Also with this same compile pix_yuv seems to be the only object that passes texture properly. pix_grey and pix_rgba seem to only pass a still image in a moving video source. See "pix_rgba_bug.pd" This is anoying because I'm trying to use live video with a pix_mask but cannot since it only seems to accept two RGBA streams, but I can't get video passing through as RGBA! (or grey)

Last and certainly least...

Looks like the first pix_video object one creates grabs the 1394 device. Any subsequent pix_video's get created, but can't grab the device so they just sit there sending (green).

Until pix_video supports multiple devices (please please), or even after, it would be useful if all pix_video objects send out the same video no matter which particular instance is attached to the device. This feature would be nice because one may have more than one pix_video in a patch (in multiple chains) but may want to switch on the fly between pix_movie and pix_video (by spigoting the gemchain) Just because there is more than one pix_video in a patch does not mean that they are indeed sending video to the screen... Maybe the last pix_video to be switch on (in a chain) could grab the video..? rather than the first one instanciated...

I could use dynamic patching to re-instanciate the "right" pix_video, but that is really ugly... I'm thinking of pix_video as a catch~ for one particular video stream sent through throw~ I think this only effects pix_video since all other pix_ objects can have a local copy of a pix...

Thanks Ben
