What technology to use for continuous video playback?

Question

Java

Hello!
I am developing a terminal that should be on the trading floor, accept money and provide some services.
Based on JavaFX technology.
While waiting for the client, you need to show an advertising video . Waiting for a client can last 9-10 hours or even a day .
The current problem: after 6-9 hours of video playback, it starts to slow down (FPS drops), and then completely freezes.
Computer configuration:
Mother: asus h110m-c CPU
: Intel i5 6500
Memory: DDR4 2133MHz 8 GB
ssd: Kingston SSDNow V300 120GB
OS: Ubuntu 14.04 LTS
mp4 video format The
following approaches were applied:
1) JavaFX. MediaView
Result: after 2 hours lags begin, after 4 it hangs. For the entire period, the CPU load is 60%, the memory is 1.1 GB (does not leak)
2) JavaFX + vlcj
Worked for 8 hours and hung. The download is the same.
3) I decided to switch to pictures with animation. JavaFX + Transitions
Memory was constantly creeping up, after 4 hours everything died
4) HTML5 video. Launched a desktop application on Electron . Loaded a page with video. Worked for 6 hours and hung.
5) I tried everything the same on Windows 7. The results are even worse.
Which tool to choose for uninterrupted video playback?

Answer 1

I haven’t fully figured out why this is so, but if you run the application with the flags for the java machine
-Dprism.vsync=false -Dprism.order=sw
which disable some kind of synchronization and install software. renderer for the JavaFX graphics library,
then everything works fine

Answer 2

Break the flow in an hour and start again. Most likely someone is eating up memory, but here you can’t do without a profiler.
