[VIDEO] Problem displaying big panoramic video

in Core Library Questions • 10 months ago

Hi

I made a panoramic video (using PTGui pro), which generated a 5500 x 768 .mov file

When I try using this in a sketch, it loads fine (no errors being shown) but it just doesn't display anything.
Is there some resolution limitation? Problem with memory perhaps? I've already upped the setting to the max but alas.

I've also tried getting the quality down, lowering fps, and such.. Doesn't seem to be helping. The file I just tried was 15fps and 1.9 Gb big. Running 4gb ram on a macosx 10.6, latest processing version.

I'll be trying this on a pc later today but its pretty important that it works on mac.

Any ideas? Much appreciated

There is a resolution limit in the compression codec.

For example H.264 is constrained to 4096×2048.

Try Theora. It's virtually limitless in terms of resolution and has wide multi-platform support.

It works with GSVideo so perhaps also Processing 2.0's video library.

Thanks for the reply, I'll see where that takes me.

I kept on trying to solve it and I got it to work with the following setup:
Processing 1.5 , while specifying size(5500,768,P2D)

It runs on both mac and windows this way, but crashes with an outofmemory exception on windows after a while.
Mac throws some errors like
java(224,0xb8aff000) malloc: *** error for object 0x1722d0: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
but luckily it keeps on running

Now, the problem is I need Processing 2.0 because I couldnt get Most Pixels Ever to work without it.
I'll let you know if Theora works!
