💅 v4l2_m2m_is_last_draining_src_buf(9) 💅

okay so bestie, welcome to the Kernel API Manual — this page is short and iconic, and we're gonna get through it together 🫶

🌸 NAME 🌸

v4l2_m2m_is_last_draining_src_buf — return the output buffer draining state in the current encoding/decoding session

✨ SYNOPSIS ✨

bool v4l2_m2m_is_last_draining_src_buf (struct v4l2_m2m_ctx *m2m_ctx ,
       struct vb2_v4l2_buffer *vbuf );

🎀 ARGUMENTS 🎀

• m2m_ctx — the m2m context assigned to the instance, given by struct v4l2_m2m_ctx
• vbuf — pointer to struct v4l2_buffer

🔥 DESCRIPTION 🔥

So this one will identify the last output buffer queued before a session stop was required — and that leads to an actual encoding/decoding session stop state in the encoding/decoding process after being processed 💅. Periodt.
