From a1d64cd4a65b4daaf9f3b434c24c2358050cadaf Mon Sep 17 00:00:00 2001 From: Ming Qian Date: Thu, 19 Oct 2023 16:36:36 +0800 Subject: [PATCH] media: imx-jpeg: Drop initial source change event if capture has been setup BugLink: https://bugs.launchpad.net/bugs/2083196 [ Upstream commit a8fb5fce7a441d37d106c82235e1f1b57f70f5b9 ] In section 4.5.1.5. Initialization, the step 4 may be skipped and continue with the Capture Setup sequence, so if the capture has been setup, there is no need to trigger the initial source change event, just start decoding, and follow the dynamic resolution change flow if the configured values do not match those parsed by the decoder. And it won't fail the gstreamer pipeline.
