font:write with RGB/texturelike. how to adress image-file? #37

Closed ozett closed 8 years ago

ozett commented 8 years ago

i am a noob at coding, but the syntax does not differentiate between RGB-numbers and picture-objects. surely my mistake, but not superclear how to adress image-objects with the same font:write where RGB numbers are expected.

can anybody help me out?

What you tried is correct, except that "texturelike" objects aren't supported on the Pi version, as it uses a completely different way of rendering text (that's a lot faster, see https://info-beamer.com/blog/performance-insights) which is incompatible with using a custom texture.

ah, cool. thanks, that drove me deeper into the samples and working examples and the doku, makes info-beamer more interesting than it was ...

cool would be showing rtsp/webcam stream insteand video-file, all with effects... :smile:

may you point this out in the wiki?

You might try loading external video streams. Just define the environment variable INFOBEAMER_OUTSIDE_SOURCES=1, then give resource.load_video an url. This feature isn't officially supported, as I don't have any experience with video streaming. But you can give it a try.

i used the evironment variable, but: "bad argument #1 to 'load_video' (invalid resource name. must be local file)"

You didn't set the environment variable correctly. I can tell, since info-beamer will put up a warning in the console output.

 $ INFOBEAMER_OUTSIDE_SOURCES=1 info-beamer /path/to/node

thanks for dont letting me alone.... :smile: you are right. works perfectly...

i did the mistake and set the environment variables in the script with the normal user, than executed the info-beamer as root. i think, that was my mistake? as i set the variable like you showed, in one line, it worked like a charm ...

Ok, good. Environment variables don't get set when running sudo, as that would be really dangerous: You could set a modified PATH which would probably lead to all kinds of problems if the called program doesn't handle that case.
