Bonjour lovely knowledgeable people,
I have a little problem with playing back videos in processing. The aim is to trigger the videos via an serial port input which works fine. The problem is that the videos are played back very laggy. I assume its because they are somehow all played back in the background. The videos are very short 2-5 seconds, but are in HD (1920x1080) and .H264 coded. They are supposed to be played back as long as the input signal is there, and fade to black when its gone. Can you please help me figure out how to avoid this problem and achieve fluid playback of the videos? That would be superb! I Have been hammering over this code for a while and I cant figure it out. Annnd, do you have any idea how to implement fading in and fading out of the videos? Tried it with tint, but can not manage it to do it fast enough. You would be a life saver! Merci, merci bien — any help is appreciated!
Love ❤️ jules
