v4l2_m2m_dst_buf_remove(9)

📦 version 7.3.1, in nixpkgs unstable

💖 v4l2_m2m_dst_buf_remove 💖

okay so welcome to the Kernel API Manual, bestie — this one is short and sweet and honestly kind of iconic in a "quiet luxury" way. it's a v4l2 mem2mem function, and its whole personality is: pop a destination buffer off the ready list and hand it to you. that's it. that's the vibe. 🎀

✨ NAME ✨

v4l2_m2m_dst_buf_remove — take off a destination buffer from the list of ready buffers and return it 🫶

like, literally. it removes it and returns it. no cap.

🌸 SYNOPSIS 🌸

struct vb2_v4l2_buffer * v4l2_m2m_dst_buf_remove (struct v4l2_m2m_ctx
*m2m_ctx );

look at that little signature. so demure. so mindful. 💅

🦋 ARGUMENTS 🦋

  • m2m_ctx — the m2m context assigned to the instance, given by struct v4l2_m2m_ctx. that's the one and only thing you gotta pass in, bestie. one argument. main character energy. 👑

🌈 SEE ALSO 🌈

the whole friend group, fr fr — this function does not roll alone. first up, the kernel file: ./include/media/v4l2-mem2mem.h, and these structs:

  • struct v4l2_m2m_ops(9)
  • struct v4l2_m2m_queue_ctx(9)
  • struct v4l2_m2m_ctx(9)
  • struct v4l2_m2m_buffer(9)

and now the squad, in the order the page gives them:

bestie the by_buf variants are right there next to the plain ones — read the names carefully, they are not the same function and mixing them up is giving chaos. 😭

that's the whole page, honestly — short, punchy, one argument, one return. ate and left no crumbs. 🍓

later, bestie — this one's filed under ./include/media, stamped October 2026, and it's waving at you from the Kernel API Manual. mwah. 💜✨
