Our converter PNG export module supports 3 built-in compression levels

• none
• default libpng compression
• optimized compression

However, this functionality is currently unused as the converter is hardcoded to always use the default compression setting. We should implement a way to set the desired compression

Expected Behavior

Better control over GAIN for LimeSDR device (not mini).
Please use example of the SDR Console Gain Control.

Actual Behavior

Signal really weak on the low frequencies even if GAIN is maximized.

Steps To Reproduce

1. Go to URH
2. Click on Spectrum Analyzer
3. Refresh device, select sampling rate to 2.5M and Gain to above middle point (also tested maxim

MGLTilePyramidOfflineRegion should have a countOfTiles method that returns the number of tiles included in the tile pyramid. The implementation would rely on the mbgl::util::tileCount() function added in #9906.

This is the iOS/macOS equivalent to #11108 for Android. It would serve as a built-in alternative to mapbox/turf-swift#47 for applications already using the map SDK, including applica

In osx/updater/updater.go, we're referencing an ancient Go package, which has moved to a new location. Right now, the updater doesn't build (should we test this on travis?).

I have analyzed video problems and below is the summary. All tested with examples/http_server.py from the pywebview-3 branch.

Windows

Cocoa

• Only video frame is displayed, video not playing. Youtube works fine. There are a bunch of flags related to media in WKWeb
