Windows Movie playing Optimisations?

May 1, 2014 | 9:30 am

I’m porting a project from OSX to Windows – not much experience using Max with Windows.

Anyone got any advice for quick loading and triggering of movies? best codecs?

I have a thumbnail menu system which grabs a frame from each movie inside a poly.
The project also involves scrubbing through clips – on the mac version I loaded .movs into a jit.matrix

Initially porting it over has resulted in pauses and crashes but maybe there is a way.

I have 36 movies of 4 and 8 seconds each. I might try making one long movie out of them and just load them into a jitter matrix when the patch opens.

Is jit.gl.hap stable?

Or are there any windows specific externals?

Thanks for listening!

I think jit.gl.hap is still Mac only, sorry nothing more constructive to say…

I’m working mostly in the mac univers, little in windows, but if, i have good results with:
1280×720,h.264, MPEG-4,
working in GPU, not in CPU
not using fullscreen attribut, but jit.window @size (of your wanted projection/image size)
working therefore with a coherent size from source to projection

what are you using (codec, resolution etc.)?

I’ve had to give up with it, temporarily at least due to frequent crashes.

Not sure what is going on with my patch but Max is crashing all the time just when dragging windows around.

FWIW I was tending towards a ram based solution.

vidvox should be releasing the windows version of the hap codec in the near future.
when this happens, the hap codec with the jit.gl.hap external will be your most efficient solution for video playback, assuming you’re using opengl.

Yes I saw this the other day: http://renderheads.com/portfolio/HapDirectShow/

Will this work with the jit.gl.hap external?

I realise Hap has amazing benefits but I wonder if it is the best choice for low latency triggering.

The decompression is obviously faster but I wonder if the large file size/hdd speed has a negative impact when it comes to actual triggering.

I guess it depends…..
