Subject: [PATCH v2 0/3] Add Rockchip VPU JPEG encoder
Date: Wed, 1 Aug 2018 18:07:11 -0300 [thread overview]
Message-ID: <20180801210714.1620-1-ezequiel@collabora.com> (raw)
This series adds support for JPEG encoding via the VPU block
present in Rockchip platforms. Currently, support for RK3288
and RK3399 is included.
The hardware produces a Raw JPEG format (i.e. works as a
JPEG accelerator). It requires quantization tables provided
by the application, and uses standard huffman tables,
as recommended by the JPEG specification.
In order to support this, the series introduces a new pixel format,
and a new pair of controls, V4L2_CID_JPEG_{LUMA,CHROMA}_QUANTIZATION
allowing userspace to specify the quantization tables.
Userspace is then responsible to add the required headers
and tables to the produced raw payload, to produce a JPEG image.
