Good thing 'he development and maintainership of Megapixels has been 
moved to gitlab.com/postmarketos/megapixels' then :-)

Could you update the URL and try again?  If you want you can report 
and/or investigate Guix's apparent failure to deal with sr.ht 
separately.

Use git-file-name here for convenience and to reduce the chances of such 
paste-os.

Please add a newline after native-inputs so you don't have to split 
inputs over 2 lines like this.  Since we're here anyway, order these 
alphabetically.

Same newline.

So... ignoring the redundant 'application', this is a one-word synopsis. 
 This seems to be for mobile devices, so 'Camera applications for mobile 
devices', I guess.

Whose obscure 'media request API'?  Why does that matter?  Etc.

This seems (more?) pertinent:

- Megapixels only captures raw frames and stores .dng files.
- It captures a 5 frame burst and saves it to a temporary location.
- It runs a (customisable? dunno) postprocessing script to generate the 
final JPEG file and saves it to the Pictures directory.
- It uses OpenGL to debayer the raw sensor data for the preview.

Etc.  Descriptions should not be 1-2 lines long.

Also update to GitLab?

I'll build this later today, but I don't expect to find any issues with 
the package :-)

Kind regards,

T G-R
