Hi,
I'm having some problems with Pd 0.50 and Gem 0.94. Debian/1:0.94-1 (in Ubuntustudio 19.10) I got the following red message on pd window:
(Tcl) INVALID COMMAND NAME: invalid command name "::pdwindow::logp55fc7}" while executing "::pdwindow::logp55fc7} 3 {[GEM:filmGMERLIN:video] Cannot skip backwards: Stream time: 30464 skip time: 28672 difference: -1792 }" ("uplevel" body line 2) invoked from within "uplevel #0 $docmds"
I still don't find the way to reproduce it but it happens sometimes when I'm using pix objects (video, film & shaders) with text2d. In other occasions there's no red message on pd window but the gui gets frozen: mouse moves but pointer doesn't change from edit mode, number boxes display same number but still send new values, also new objects doesn't visually appear even though they are created.
Any help would be appreciated.
thanks & regards a rc
Hello,
it seems the problem is related with gmerlin backend for reading and scrubbing a video file. in gem folder you have other backends, such as vlc .
you can try look to inside gem folder, and try to see what backend works best for you, by removing (moving the plugin outside of gem folder.)
i'm not sure.

Hi, thanks for the quick reply! I did: sudo apt-get install gem-plugin-vlc that's the backend you're talking about?
best regards, a rc

?? afaict py was not talking about any specific plugin (rather that you should find our which one works best *for you*, by eliminating those that dont. (and since you use 'apt' for installing Gem and it's plugins, you should just remove the various 'gem-plugin-*' packages to test things, rather than move files around as was suggested)
in any case: gem-plugin-vlc is most likely *not* what you are looking for, as this only works with [pix_video]: you can use it to open films, but it doesn't allow for seeking and the like.
in general, GMERLIN is the "best" plugin for film playback. you might also have luck with the quicktime4linux plugin (gem-plugin-lqt).

this might be a multi-threading bug, where the GMERLIN backend attempts to write error messages while while other messages are being sent to the GUI, thus creating garbage. this would also explain why the problem is so hard to reproduce.
try running pd with the "-stderr" flag, and see whether the problem goes away.
