It's alive! D building D building D, all on Android
After a sleepless night of trying to build the latest ldc master branch 2.070.2 on my Android tablet a couple nights ago, almost the full druntime/phobos standard library test suite passes (only one assert in std.conv) and the same for the dmd test suite, with a handful of failures across three modules exclusively testing C/C++ ABI compatibility. The 2.070 frontend is written in D, ie ddmd, and also natively compiled on the Android tablet by ldc 2.068 (alpha build available here, first download link - https://github.com/joakim-noah/android/releases/tag/polish), hence D (2.068) building D (2.070) building D (tests, apps, etc.). :) Of course ldc 2.068 was itself built natively on Android, using the Termux Android app and the dev tools that it comes with (https://play.google.com/store/apps/details?id=com.termux&hl=en). Using ldc and Termux, it's possible to build an Android app from scratch _on_ your Android device, by following these instructions: https://github.com/termux/termux-packages/issues/63#issuecomment-184115581 It only took a single night of tweaking to build this because of all the great work many contributors have put in over the past year. First, there's all the work that Walter, Daniel, and others have put into C++ integration, as ldc is now a moderately large mixed D/C++ codebase (Dscanner counts 62.5k klocs of D in the ddmd frontend, plus ldc's C++ layer and how many ever umpteen lines are invoked in llvm's C++ codebase). Dan got the full ldc testsuite working on the Raspberry Pi a couple weeks ago (https://github.com/ldc-developers/ldc/issues/1283), in the process fixing several ARM codegen issues that were hitting Android/ARM also. Finally, there's all the great work put into ldc recently by Johan, kinke, Dan, Rainer, and of course David and Kai, to integrate the new D frontend with llvm and get ldc working on new platforms. I'll look at getting JNI working next, along with finishing up a translated C++/OpenGL ES 2.0 sample app (https://github.com/googlesamples/android-ndk/tree/master/Teapot). A linux->Android cross-compiler will need the in-progress work to cross-compile reals, have to look into that. Once those issues are rounded up, I'll release a ldc 1.0.0 beta for Android sometime this month.

I've tried it on a Sony phone and a Samsung tablet, both with the HTML5 player in the browser and the Android app. All other streams work, which suggests it's a problem with the Dconf stream. My guess is that the Dconf stream is using an audio codec that Ustream doesn't support on Android, and it's silently failing, in more ways than one. If anyone else can reproduce this and maybe try to fix it by changing the audio codec, if possible, that'd be great. Have reported it to A/V team, will see if they can fix it timely. Can it be html5 ? https://support.ustream.tv/hc/en-us/articles/208999037-New-Ustream-Player-Overview Sound doesn't work in the official Ustream Android app either for the Dconf stream, as I noted. My guess would be that the HTML5 player and the Android app try to use whatever audio codecs are built into Android, instead of the app using its own codecs, and the codec chosen by the Dconf livestream is not normally supported on Android for whatever reason. Also, no audo with iPhone or OS X. Even downloaded Ustream app. Must be an upstream problem. Looks like Kai is giving a nice talk though. Doeme on the irc channel #D found an archived Ustream link that works on VLC and MX Player on Android, I extracted the other three.

Still no audio for the live stream. Does anybody have audio working live? What are you using to listen with?

Yes, you can get new stream URLs from the JSON metadata for each video. For example, the first video is at http://www.ustream.tv/recorded/86352137, so load up http://api.ustream.tv/videos/86352137.json and look for the flv URL with the tcdn.ustream.tv domain. Copy it, remove the forward slashes before the back slashes, and paste it into VLC.

It almost sounds like we would need a safe union and unsafe union type and do some extra stuff for the unsafe union, but I'm just starting to learn about this stuff.

In our case there is one main window and a few other windows get opened one at a time (Platform.instance.createWindow with WindowFlag.Modal), increasing number of open windows to 2, and sometimes native dialogs are invoked in addition to the 2 DLangUI windows. I remember there was some glitches like if you press Enter in OS-native file dialog and it gets closed then an odd Enter key press message may be received by DLangUI window, but we used one simple trick: before opening some modal window change focus in current window to something harmless. After that everything worked quite well. But we're not using more than one active (i.e. not shadowed by a modal one) window at a time, so don't meet with issues you might meet there.
