Out of Memory Problems with GSVIDEO

in Contributed Library Questions • 2 years ago

Following sketch will stop with an error after a while. The Error message says my mac is out of memory. Everytime i load a new video, i delete the old one, but still it seems that something will fill my memory all the time. Would be very very nice, if someone can see the solution.

please, please, i really need help. cant find a solution. i need a working version in 12 hours!!!

dont be afraid of the long code example... i think the error must be in this part:

void playVideo(String vidNum) {

if (movie != null) {

movie.stop();

movie.delete();

}

println("Video "+vidNum+" is playing");

movie = new GSMovie(this, "video"+vidNum+".avi");

movie.play();

// movie.volume(0);

}

evertime i start playing a new video, i delete the old one.... but it seems nothing gets deleted.

all videofiles together are 1.6 gb big.... i am not sure if i can solve the problem if the videos are smaller?

GSvideo 0.9 includes the memory-leak fixes that resulted from the discussion in this thread. Also, the dispose method you use in your code should free up the memory associated to the movies. Maybe what you are experiencing is due to another memory handling issue in GSVideo and/or GStreamer that I haven't observed myself yet...

However, it seems to me that you have a relatively small set of videos (10 - 20) that get played depending on the event being trigger in your app. What you could do, instead of recreate the video in each event, is to load all the videos during setup and put them in paused mode (this doesn't store the entire videos in memory, only one frame for each so you shouldn't run out of RAM).

So, when the method playVideo() gets called, you just paused the currently playing video and start playing the new one. Does this make sense?

If this idea doesn't work, all I can suggest at this point is to switch to a different video library. What is the resolution of your videos? If is not too high, you can probably rely on the built-in video library, or something like jmcvideo.

I hope this helps.

thanks for your input. it came just some hours too late :)

i solved my problem the way you described in your first idea: loading all videos on startup. the only issue now is, that sometimes when a clip plays again it shows its last frame at the beginning. i cant see, when its happen. the only thing i can say, is that the very first time the clip starts playing, everything is fine and on the second run i will get the last-frame-thing.

the playVideo function looks now like this:

void playVideo(int num) {
if (num != currentVideo) {
clips[num].jump(0);
clips[currentVideo].pause();
}

clips[num].jump(0);
clips[num].play();
currentVideo = num;
}

jump(0) or goToBeginng makes no difference.

i think this has nothing to do with my memory problem. should i make a new topic out of this problem?

Re: Out of Memory Problems with GSVIDEO

The last frame issue is probably due to the fact you are calling jump() either before pause() or play(). In the first case, you pause the stream right after issuing the frame jump call, so the frame is actually not changed. In the latter case, you jump while the video is still in paused state. I recommend doing something like this:

void playVideo(int num) {
if (num != currentVideo) {
clips[currentVideo].pause();
}
clips[num].play();
clips[num].goToBeginning();
currentVideo = num;
}
