Subject: [PATCH] media: amphion: fix decoder's interlaced filed
Date: Tue, 12 Apr 2022 18:51:56 +0800 [thread overview]
Message-ID: <20220412105156.17091-1-ming.qian@nxp.com> (raw)
For interlaced frame, the amphion vpu will store the
two fileds sequential into one buffer, top-bottom order
so the filed should be set to V4L2_FIELD_SEQ_TB.
fix the previous bug that setting it to V4L2_FIELD_SEQ_BT wrongly.
