target_framemode(3) Arcan Lua API target_framemode(3) NAME target_framemode - Hint to the target frameserver to restrict frame deliv- ery. SYNOPSIS nil target_framemode( tgtid, skipval, prewake, preaud, skipdbg1, skipdbg2 ) DESCRIPTION Some frameservers can be instructed to ignore transferring frames with deadlines that cannot be matched. The semantics for skipval: -1 ( NONE ) -- always deliver every frame, stall if necessary. 0 ( AUTO ) -- the frame- server is responsible for only delivering relevant frames. 0 < n <= 9 ( STEP n) -- only process every n frames, retain clock. 9 < n < * ( FASTFWD ) -- only process every n (n - 9) frames, fast forward clock. prewake de- termines how far in advance of the next deadline frame generation should begin. preaud forcibly desynchs A/V clock n frames in order to allow some buffering. *skipdbg1/skipdbg2* if these are set to > 0, random() jitter sleeps are inserted before generation and transmission to troubleshoot / optimize timing in the main process. NOTES 1 Switching skipmode may force an audio buffer flush. 2 Only libretro follows this pattern at the moment, but decode and hi- jack libraries will be updated to include support. hijack and de- code will also targetcontrol August 2026 target_framemode(3)
