Re: [PD] [announce][Gem] well, here it is....

hi ! thanks for keeping bug-reporting

2) When I switch the input to RGBA things slow down quite a bit. I'm

running an 800 MHz Duron with a Voodoo3 AGP card, I realize it's outdated, but should I expect such a significant slowdown ? 3) Is it possible to convert an RGB movie to RGBA via a format converter ? Is there such a thing for Linux ?

you mean, using the "pix_rgba" object (which might be (pre-alpha) crashy)) it slows down ? most of the decoders only return RGB instead of RGBA, but all of them are able to decode to RGB. however, this depends on the used codec, so it might be up to you to use a codec that supports RGBA or use pix_rgba to make a "manual" conversion.

4) Performance seems "brittle", i.e., sometimes certain MPEGs will

load and play nice, at other times the same files will load but not play.

try loading the file after turning on the rendering

5) Often when I destroy the GL rendering window Pd will close with

this output:

X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 128 (XFree86-DRI) Minor opcode of failed request: 13 () Value in failed request: 0x2e00004 Serial number of failed request: 36 Current serial number in output stream: 36 [dlphilp@localhost dlphilp]$ pd_gui: pd process exited

Is this a known bug ?

No, maybe it has something to do with your GraphicsCard ? (but i guess this behaviour started with the new gem and did not happen before...)

6) pix_movie doesn't seem to work at all. Pd crashes when I try

lading an MPEG, and the MOV files that work with pix_film don't display with pix_movie. I get a flickering brownish window during the rendering, but no video. Also, if I try changing the named file in the pix_movie object Pd will often crash.

this is very(!) strange, since pix_film and pix_movie use the very same procedure-calls (eg: for opening files). the only difference between these two is, that pix_movie immediately loads the frame as a texture onto the gfx-card, whereas pix_film does not. however, the "brownish look" of your window comes from using the wrong colour-space (i guess: RGB instead of RGBA...) i'll check this.
