[PATCH 0/2] media: nxp: imx8-isi: Fix single frame capture and optimize buffer usage

Posted by Guoniu Zhou 4 weeks ago

This series fixes a hang issue when capturing single frames and improves
buffer utilization by prioritizing user buffers over discard buffers.

Patch 1 reduces min_queued_buffers to allow streaming with a single buffer,
fixing hangs in applications like libcamera's cam tool.

Patch 2 changes the buffer selection logic to use pending user buffers first,
minimizing unnecessary frame drops at stream start.
