Hardware and configuration optimization on macmini for video

Hello,

I’ve got problems on Max6 with a patch using a lot of access to video files and writing sound files to the hard drive at the same time…
I need to use it a full day on a macmini and it crashes.
the patch works perfectly during 3 hours and the video freeze.
I tried to copy videofiles on an external hard drive, so I read the video files from the external HD and I write and read audiofiles on the internal drive on the macmini, and the problem is the same… after 3 hours Max crashes (no answer), the video freeze on the screen (the audio continue playing…)
So does someone has an idea to optimize the configuration of the macmini. I don’t know if the problem comes from RAM or Hard drive or something else…

thanks…

what kind of macmini you have?

maybe post a patch ?

what codecs/resolution you use?

what messages are in the console window ?

It’s the last macmini (2011) (the best configuration selled on apple store 2,5 Ghz intel with 4gB ram)
I use Hd video 1920×1080 quicktime movies with a photojpeg codec (approximately 2 minutes each video) but i need in the patch to use a lot of “read” jit.qt.movie. I use the opengl method to optimize and it works great when i’m not writing/reading sound data at the same time.
I would like to use this player and write sound data at the same time and when i do this the video freeze sometimes, nothing in the console windows but finder tell me that max don’t answer…
I think that the computer or the app don’t like to read a lot of different videofiles during sounddata are writed on the hard disk and red to… but i’m not sure…
I tried to put video files on an external hard drive and soundfiles on an other and the problem is the same.
Have you ever had this kind of problems ?

Thanks…

With this little information, it’s hard to make a guess, but one thing you might try is to separate the video and audio sections and run them in two different instances of Max….

Maybe make sure you’re not trying to read any of the files that you’re in the process of writing to.
