From: Nicolas Dufresne To: Adam Ford Cc: "jernej.skrabec" , linux-media , kernel , Chris Healy Date: Fri, 28 Jan 2022 13:35:15 -0500 Content-Type: text/plain; charset="UTF-8" User-Agent: Evolution 3.42.3 (3.42.3-1.fc35) MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Precedence: bulk List-ID: X-Mailing-List: linux-media@vger.kernel.org Hi Adam, Jernej and I had to deal with user report which show a stride issue with the G2 on Allwinner H6. https://forum.libreelec.tv/thread/17565-nightly-images-for-a64-h3-h5-h6-and-r40-boards/?postID=166086#post166086 We quickly found that the stride alignment set to 16 needs to be 32. Though we noticed that this is only needed when using the G2 postprocessor (NV12), while it worked fine with tiles (NV12_4L4). We were wondering if you, or anyone here on the list could test this on IMX8MQ and IMX8MM. We'd like know if this is specific to the older G2 on H6. To trigger this, you need a video with a resolution like 1552x1080 as used in the report. We can help you get one if needed. regards, Nicolas
