@linmob Cool, thanks! Fascinating to see #postmarketOS continuing to make inroads towards fully mainlining hardware not specifically designed to run Linux (eg the Pixel3A) as well as what's happening with PlasmaMobile and Phosh! Glowup also looks really cool, although it would be nice to actually have it potentially do it's thing directly from one of the camera apps.
Thanks for putting together this smorgasboard of #LinuxMobile news!
@Blort Thanks!
Regarding Glowup and other post-processing things - I've been thinking about (but not communicating to the people who do camera stuff -- cc @dos, @martijnbraam ) coming up with a "postprocess nicely while idle and connected to a charger" - much like an iPhone does for stuff like generating highlight albums or person recognition.
This combined with a low-res, fast preview image generated when taking a picture could be a way to do this on slower hardware.
@linmob @Blort @martijnbraam Martijn also mentioned remote postprocessing some time ago, which makes sense too - my laptop does in 4 seconds what my phone does in 30.
The hard parts are there, what's left is some simple glue. I'm trying to encourage people to do this kind of nice entry-level tasks. Writing glowup.py took me just a few hours of fiddling with libadwaita in total, which would be better done by someone who'd like to learn this stuff and actually take it somewhere further.
@dos @linmob @Blort @martijnbraam Does it really take 4 seconds on a laptop? Is it running on the CPU or GPU?
Because maybe if such a process is running on more powerful hardware, I think it's smarter to utilize compute shaders if possible (be it OpenGL or Vulkan).
@thejackimonster @linmob @Blort @martijnbraam darktable uses OpenCL when available.
@dos @linmob @Blort @martijnbraam I see. Then it's really heavy post processing, I assume. ^^'
@thejackimonster @linmob @Blort @martijnbraam It's certainly optimized for quality rather than performance ;)
For the phone use-case, I see it as a stop-gap. I used darktable because it was there; that's what I used for manual RAW handling so I knew how to make it output something nice. I bet you could write a much more performant and suited-for-mobile processing pipeline with good enough results, but that's a bit more involved than some UIs and glues 😜
