v4l2_m2m_mark_stopped(9)
π v4l2_m2m_mark_stopped β the vibe check for "we're done here" β¨
Okay bestie, so this is a page from the Kernel API Manual (yes, the kernel has a manual, she's fancy like that π) and it's about one tiny little function that flips the current encoding/decoding state over to stopped. That's it. That's the whole gig. Let's get into it π¦
β¨ NAME β¨
v4l2_m2m_mark_stopped β sets the current encoding/decoding state as stopped, periodt π
πΈ SYNOPSIS πΈ
void v4l2_m2m_mark_stopped (struct v4l2_m2m_ctx *m2m_ctx );
Not me copy-pasting this exactly β okay yes I am, but literally the whole signature is that one line, it's giving minimalism icon π
π«Ά ARGUMENTS π«Ά
m2m_ctxβ the m2m context that's assigned to the instance, and it's given to you as astruct v4l2_m2m_ctx. Like, that's the only thing you hand her. One argument, zero drama π
π₯ SEE ALSO π₯
Okay so the original page lists the kernel file ./include/media/v4l2-mem2mem.h and then literally the entire friend group π β structs and functions, all with (9) after them, all lowercase, all iconic. Here's the whole squad, no one gets left behind:
