vb2_streamoff(9)

💅 vb2_streamoff(9) 💅

okay so we are in the Kernel API Manual, and this page is literally the vb2_streamoff stop-streaming moment. bestie, it’s giving “wrap it up” energy for videobuf2. 🎀

✨ NAME ✨

vb2_streamoff — stop streaming. periodt. 💖

🌸 SYNOPSIS 🌸

int vb2_streamoff (struct vb2_queue *q , enum v4l2_buf_type type );

🎀 ARGUMENTS 🎀

• q — pointer to struct vb2_queue with videobuf2 queue. that’s the queue bestie. 🫶
• type — the type argument passed from userspace to the vidioc_streamoff handler. yep, that one. ✨

🦋 DESCRIPTION 🦋

bestie, this should be called from the vidioc_streamoff handler of a driver. no cap.

here’s what this function does:

1. verifies current state
2. stop streaming and dequeues any queued buffers, including those previously passed to the driver (after waiting for the driver to finish)

this call can be used for pausing playback. lowkey iconic. 🎀

the return values from this function are intended to be directly returned from the vidioc_streamoff handler in the driver. like, hand them straight back out. 💅
