From d1713de60ab5c37c5b2de63fd75cb5b5e59248c5 Mon Sep 17 00:00:00 2001 From: Vedant Paranjape Date: Fri, 24 Sep 2021 14:08:21 +0530 Subject: test: gstreamer: Add a test for gstreamer multi stream This patch adds a test to test if multi stream using libcamera's gstreamer element works. Test will run only on devices that support multistream capture, eg., devices that use IPU3 and raspberrypi pipeline. This was tested on a Raspberry Pi 4B+.
