From f215f0815cf8f13e4a86a079f4e44eeee545396b Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 2 Nov 2023 00:21:12 +0100 Subject: [PATCH] chromium: Add v4l2 m2m stateless decode configuration options Add configuration options to enable hardware video decoding using stateless V4L2 M2M device. This allows offloading e.g. h264 video playback to Hantro VPU on i.MX8MP where this was tested. To make that work, enable 'use-v4l2' and 'proprietary-codecs' PACKAGECONFIG. This commit was implemented with much great help from Jianfeng Liu .
