+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
+
+Upstream-Status: Pending
