19:37 | paulk | hi folks! just rediscovered apertus after a few years off my radar, glad to see the project is still alive!
| |
19:38 | paulk | I recently got interested in building my own a/v gear with only free software embedded stuff
| |
19:38 | paulk | and at the end of the line is making a camera
| |
19:39 | paulk | what I have in sight is to use SoCs like Allwinner or Rockchip with mainline Linux support and capture + isp capabilities
| |
19:39 | paulk | instead of a fpga+cpu approach
| |
19:40 | paulk | (i.e. isp is in the SoC silicon)
| |
19:41 | paulk | especially on the Allwinner side I've been working on v4l2 drivers for MIPI CSI-2, capture and ISP support
| |
19:41 | paulk | https://patchwork.kernel.org/project/linux-media/list/?series=691734 for the isp series
| |
19:43 | paulk | similar (even more advanced) is already available for rockchip
| |
19:43 | paulk | so that means MIPI CSI-2 sensors which are typically not the most advanced
| |
19:44 | paulk | best I could find that's easily sourceable and not crazy expensive is the raspberry pi hq camera
| |
19:44 | paulk | which is imx477
| |
19:45 | paulk | though some newer generations of Allwinner seem to support LVDS and sub-LVDS
| |
19:45 | paulk | with up to 16 chans IIRC
| |
19:45 | paulk | anyway another area of interest is h.264 encoding
| |
19:46 | paulk | (also would be interesting to see if I/O holds for storing raw frames)
| |
19:47 | paulk | I wrote some PoC for the Hantro encoder (in Rockchip SoCs) https://github.com/bootlin/v4l2-hantro-h264-encoder
| |
19:47 | paulk | And there are bits and pieces around for Allwinner too
| |
19:48 | paulk | so anyway, it's not as high-end as the AXIOM and taking a different approach but just wanted to let you know
| |
19:49 | paulk | oh and also I would be interested in writing a mainline v4l2 driver for driving Canon EF lenses through SPI
| |
19:49 | paulk | in case that can be of interest to anyone around here
| |
20:11 | davidak[m] | FYI: https://nofilmschool.com/details-emerge-atomos-8k-image-sensor i don't think we need 8K (yet), it's still interesting
| |
22:02 | Bertl | paulk: sounds interesting ... keep us updated!
| |
23:05 | vup | paulk: what is the maximum size and framerate hthe h.264 encoder can do? And is it a hard ip block or some more generic vpu dsp like thing like on the pi's?
