From bc43061b42c0179a399d46c85115fe13831485ec Mon Sep 17 00:00:00 2001 From: Ming Qian Date: Fri, 14 Apr 2023 09:55:42 +0800 Subject: [PATCH] media: amphion: drop repeated codec data for vc1l format [ Upstream commit 668ee1a3a1870381225002c246972419b98e4253 ] For format V4L2_PIX_FMT_VC1_ANNEX_L, the codec data is replaced with startcode, and then driver drop it, otherwise it may led to decoding error. It's amphion vpu's limitation Driver has dropped the first codec data, but need to drop the repeated codec data too.
