Have you checked RAM and hard disk usage while playing the movies? Is it just a specific part of certain clips that slow down or do all clips do it?

Hello,
I come back with my problem. I try different option on the nvidia driver (180.44) in the part opengl settings and antialiasing settings but nothing new. I always get slowings down on my movies. They seem to start during long scenes of the movie (no logic here, i know, but it is what i observe). Any help ? ++

Hi,
Maybe this won't help at all (I only use gem on windows), but just in case it does:
Does it work as expected if you disable the "auto" mode and pass the frame number to the right outlet?
I done a counter with a metro and not with gemhead because the framerate pass from 25 to 7 then back to 25, etc. Then it should not change anything compare to [auto 1(. On Linux, the movie is played at each frame render but the rate is not really constant. It was much better on my old Powerbook G4 and MacOSX :) Is there a minipulation to do on the NVidia driver (v. 180.44) ? I know that each frame is render when the buffer is ready with OpenGL (swap buffer in double buffer). But here the swap is very very slow on my brand new Qosmio with a NVidia 9700M GTS ! :))) And this is the same in single buffer mode with :
[1 ( | [metro 40] | [t b b] | | | to right inlet of pix_film | to gemhead
Play a movie with the help patch of [pix_film] at a almost constant rate would not be possible on Linux, i really don't think that it is correct. So, if someone can help me, please ! ;) Thanx a lot. ++

If the answer is yes, than a workaround would be:
[gemhead] | [t b] | [any implementation of a counter] | (to the right outlet of pix_movie)
I am not good at ASCII art, but if you want a frame rate different than 1:1 (meaning one movie frame per gem frame), you can implement the "counter" with necessary calculations and roundings to get the needed frame number.
Obviously, if the answer to the initial question is "NO" and/or if the framerate unstability you describe is not only in the playing of the pix_movie but also in the framerate of the gemwin, then all this won't be of any help.
I always use this technique (well it's too simple to call it a "technique") and never the "auto" mode even if I have never experienced problems with auto: the fact is that this also lets you easily control the playing speed. But I have to say that I have only used codecs that compress each frame separately (namely DV-PAL in my case); with any codec that uses
previous
frames to decode a given frame, this method may give, I guess, problems of performance.

The behavior of [pix_film] is not the same on Macosx and on Ubuntu. What is described in the help file seems to work only for Linux OS. I am a newbie on Ubuntu, that's why i am a little surprised to have a different behavior between the two OS. And, if i'm right, the movie doesn't play each frame on MacOSX and it play in loop when you click
on
[auto 1(. However, you are right on Linux ;) I have tested and see that the
frame
started at 25 and go down to 7 ! So my question is : how to have a approximate 'constant' frame rate ? (to send a bang to [gemhead] with a [metro] changes not at all the problem). Thanx. ++

In the helpfile to pix_film is written:
use the "auto" message, to automatically proceed to the next frame each rendering cycle.
that means that the movie is never played back according to a header information about the real fps, but according to the frame rate the gemwin is running at.
so i the behavior you are describing is expected. no movie will run just like in VLC other than purely by coincidence. please correct me if i'm wrong.

Hello,
I encounter a problem to play movies at normal speed with
[pix_film]
and [pix_movie]. I tried with a .mov (photo JPEG) and a .avi movies. During the movie play, sometimes the movies go fast, sometimes they go slowly. I use the message [auto 1( to start the movies or the second inlet with a counter but still have the problem !? So i think i have something wrong with Pd (or Ubuntu) and not GEM. For information, all is ok to play these movies with VLC. Can you help me to configure something wrong on my computer ? :) Thanx a lot !
Here my configuration : Pd version 0.41.4-extended GEM: ver: 0.92.CVS GEM: compiled: Jun 15 2009 Ubuntu 9.04 GPU : Nvidia 9700M GTS
