define_feedtarget(3) Arcan Lua API define_feedtarget(3) NAME define_feedtarget - Create a direct copy association between two frame- servers. SYNOPSIS subseg define_feedtarget( dstvid, srcvid, cbfun ) DESCRIPTION In rare cases, the recordtarget approach for creating output segments in connected frameservers is too expensive or complex. The define_feedtarget function is intended for situations where the input data from one frame- server should be copied exactly over to another without the possible GPU roundtrip. As such, no shaders, transformations or audio will carry over to the output. For this to work, target_flags(srcvid, TARGET_VSTORE_SYNCH ) should also be toggled so there is a local data buffer to work with. NOTES 1 define_feedtarget does not handle dynamic resizes inside the srcvid. If source dimensions change, the subseg frameserver connection will be terminated. 2 This can also be used for debugging issues with recordtargets, calctargets, streaming textures and graphics drivers as it creates a synchronized copy that is treated separately from regular textures.
