💅 v4l2_m2m_up...eaming_state(9) — from the Kernel API Manual, bestie 💅

okay so real talk, this page is v4l2_m2m_up...eaming_state(9) (yes the name got truncated with ... in the header, that's just how the manual renders it, not a typo on your end, breathe 🫶). It's a kernel API page. It's short. It's sweet. Let's get into it ✨

🌸 NAME 🌸

v4l2_m2m_update_start_streaming_state — updates the encoding/decoding session state when someone asks for a start of streaming on a video queue. that's the whole vibe. it's the "we're going live" button but for your mem2mem session 🎬

⭐ SYNOPSIS ⭐

void v4l2_m2m_update_start_streaming_state (struct v4l2_m2m_ctx *m2m_ctx
, struct vb2_queue *q );

literally that's it. returns void, takes two pointers, does not miss 💅

🎀 ARGUMENTS 🎀

  • m2m_ctx — the m2m context that's assigned to the instance, handed to you as a struct v4l2_m2m_ctx. it's giving main character energy, it's the context of the whole thing ✨
  • q — the queue. yeah. that's the description. queue. iconic minimalism, ngl 😌
