YUV video mode

Hey all

I’ve got a patch where i need to be able to switch between 6 videos (fade one out, fade another one in)
this will go on for about 8 hours so needs to be pretty stable.

I’ve got 6 FileStream nodes feeding into 6 VideoTexture nodes
when I use normal VideoTextures I get no colour data, when I choose YUV VideoTextures it looks fine, BUT the 6th one doesn’t work, and sometimes the 5th doesn’t either.

This problem doesn’t occur with standard VideoTextures, any ideas why i’m not getting colour with those? VirtualDub says it’s outputting RGB, but maybe FFDSHOW/ h264 codecs just ouput in YUV anyway and the filtergraph cant convert?

thanks!

got round it by using one filestream only
seems more elegant, but can’t vvvv hack that much video all at once?

that shouldn’t be a vvvv issue. there is a known limit of videotextures that can be used in parallel, that seems to be graphiccard dependent. i never heard it was at 6 though… can you tell us more about your hardware?

this must be a codec issue. if you are familiar with graphedit you could do some debugging on this…
