+Subject: [PATCH] HACK: gstv4l2object: Increase min buffers for CSI capture
+
+With default min buffers, frame drops are observed with CSI capture
+pipeline with VISS, LDC and DSS with DMABuf Import mode
+
+Increasing min buffers queued in v4l2src seems to fix this issue.
+Need more amalysis on the exact root cause
+
NAK. This patch file is missing an Upstream-Status entry. There are
now QA checks in master that require that to be present for long term
auditing purposes. More info can be found at:
https://docs.yoctoproject.org/contributor-guide/recipe-style-guide.html#patch-upstream-status
Please fix and send a v3.
