Subject: [PATCH] media: s5p-mfc: copy timestamp and timecode in encoder output
Date: Tue, 29 Oct 2019 11:48:35 +1030 [thread overview]
Message-ID: <20191029011835.4733-1-mihailescu2m@gmail.com> (raw)
When using the Samsung Multi-Format Codec (MFC) for hardware assisted encoding,
output buffers are missing timestamp and timecode information. This patch copies
the v4l2 timestamp and timecode fields to the MFC output buffer from the
corresponding input buffer.
