Subject: [PATCH v4 0/2] Enable JPEG encoding on rk3588
Date: Thu, 18 Apr 2024 16:15:04 +0200 [thread overview]
Message-ID: <20240418141509.2485053-1-linkmauve@linkmauve.fr> (raw)
Only the JPEG encoder is available for now, although there are patches
for the undocumented VP8 encoder floating around[0].
This has been tested on a rock-5b, resulting in four /dev/video*
encoders. The userspace program I’ve been using to test them is
Onix[1], using the jpeg-encoder example, it will pick one of these four
at random (but displays the one it picked):
% ffmpeg -i <input image> -pix_fmt yuvj420p temp.yuv
% jpeg-encoder temp.yuv <width> <height> NV12 <quality> output.jpeg

Changes since v3:
- Keep all the previous tags, sorry I forgot to do that in the previous
version.
- Remove an extra media: in the first patch.
Changes since v2:
- Only expose a single VEPU121, since the driver doesn’t yet support
exposing them all as a single video node to userspace.
Changes since v1:
- Dropped patches 1 and 4.
- Use the proper compatible form, since this device should be fully
compatible with the VEPU of rk356x.
- Describe where the VEPU121 name comes from, and list other encoders
and decoders present in this SoC.
- Properly test the device tree changes, I previously couldn’t since I
was using a too recent version of python-jsonschema…
