encoder view speedup!

Notes:

• the encoder webview now runs better/faster/more efficiently!
  • draws to screen on background thread. This is most visible as a more stable framerate on older devices.
  • file loading (at the start of encoding) should be much snappier
• the decoder now makes a best-effort attempt to set the mime type of a file at save time. Some android devices won't set the file type properly without this.
• misc other bugfixes and speedups

a maintenance release, sort of

Notes:

• partial app rewrite for opencv 4.12. Everything should look and act the same (the changes are as minimal as possible), but we basically swapped out the engine of the car.
• the release apk now uses a custom opencv build (.so) for size and speed reasons. (https://github.com/sz3/opencv-tinyso/releases/tag/v4.12)
• performance improvements: Code should run faster (cooler) than everything since the older opencv 4.4 builds. Hooray?
• newer NDK, newer gradle, misc other dependency upgrades. Blah blah blah

Misc:

• we're going to give the arm32 build another try. Stay tuned!

Misc2:

• recompiled (incl. opencv 4.12) for 16kb page sizes (oops) as version 0.6.6g (internal version '25', since 24 already made it out), behavior and code will all be identical, but the play store is marginally happier about the app. If you can't decide which version to choose, I recommend a coin flip :slightly_smiling_face: .

Mode Bu, and an in-app encoder!

• introducing compatibility/reliability mode Bu, a miniature (dare we say: micro) version of the mode B config.

  • as with mode Bm, the motivation is a broader range of compatibility. Unlike mode Bm, Bu is not a compromise between speed and compatibility -- it's goal is provide a working configuration of "last resort".
  • This mode is slower under ideal conditions (~43% of mode B), but it should be more reliable on a broader range of devices.
  • B > Bm > Bu in overall speed. (4C ~= B, if your screen colors are accurate)
    • You'll want to use the fastest one that reliably works for your scenario...

• also introducing a (beta) in-app encoder!

  • thanks to @mrwm for putting the webview code together! (#57, #60)
  • swipe vertically (up or down) to switch between the encoder and decoder view! This may make phone <-> phone transfers easier...
  • the encoder will likely be slower than in-browser performance, but it should work in a pinch. ... hopefully... More improvements will hopefully make it in down the line. :slightly_smiling_face:

build notes:

• this may be the last release using opencv4.8. We shall see.

Mode Bm!

• introducing experimental mode Bm, a more compact version of the mode B config.
  • This mode is slower under ideal conditions (~70% of mode B), but it should be more reliable on a broader range of devices.
  • The new mode has been added to the auto-detect logic, so select it on the encoder side (ex: at https://cimbar.org, or via the latest libcimbar release ) and give it a try.

build notes:

• opencv4.8 is now the default opencv.

addendum:

• I tagged the wrong commit for this release initially. This is the right one :upside_down_face:
