Будет это подарок под новогодние праздники или приложение выпустят в начале 2014 года — пока точно неизвестно. The reason is its management, that is arrange in fine manner. Нам пока остаётся только ждать новостей и надеяться на скорый релиз хотя бы первой версии. From poor critical reception, to low sales. But the way it is finally over, and VLC for Windows 8 is here.
Jean-Baptiste Kempf, president of VLC, gave an update on the progress of the WinRT VLC app. One of the major problems VLC faces is an enormous amount of legacy code written for the traditional desktop environment and not within the limitations of WinRT. There are a number of symbols forbidden in the Win8 Metro environment, VLC had over 600 of these in their code and have been working on eliminating these one by one. They are now down to getting rid of the last 16 forbidden symbols, an additional 32 remain if they want to add some network functionality to Metro VLC Win8 app. Hello, We are still working a lot of time, with almost a couple of persons spending most of their time on the WinRT port of VLC media player. The biggest issue is that we have not managed to pass the store validation yet, because the VLC backend is not ready yet. VLC backend on WinRT Reminder: So, the core of VLC and most of the modules, named libVLC, are the target to adapt to run on WinRT. The UI will integrate this core to show the videos. As I previously explained, the build process of VLC is not integrated with Windows Tools, notably Visual Studio, because VLC uses Unix Tools to run on all platforms. The main objective of the KickStarter was the compliance of this core to the WinRT Store Application limitations. The security enforcements SafeSEH, packagedlibraries where quickly done and backported to the main VLC port. The forbidden symbols were a bit more complex. Forbidden calls When we started the project, we had over 600 unique symbols Windows API calls used in VLC, for a total of over 15000. We are now at 16 left. And 32 more if we activate the networking code. This is cool, but not enough, since we must be at 0 to enter the store. Simple symbols replacements Some symbols were easy to replace, when you knew that you are targeting only Windows 8, because they had some similar methods. So, for each symbol, we provided a replacement with a newer API. This was quite long, but easy to do You can see the result of our work here:. Removal of code and Unicode The second part was to remove some code in VLC that was not meant to be used in WinRT mode; this was mostly the code for the Console, the multimedia timers and some NT services. This improved the port of VLC media player for Windows, not only the one on WinRT. We also removed some code from libVLC to move it to VLC, when it made sense. This is a good move for libVLC, in general. Finally, we moved all the code of VLC and the dependencies 8 millions LoC to UNICODE and Wide Chars. Once again, a task not too difficult, but a bit boring and long. Most of that part was done mid-March. Then we hit a wall. MSVCRT The wall is called MSVCRT, aka Microsoft C Runtime, the equivalent of the libc, the C standard library, Every version of Visual Studio and Windows comes with a new version, with version numbers from 2. It is often a dependency headache for big projects. Most open source projects use the old version named msvcrt. But on WinRT, one MUST use MSVCRT 11. This meant that we had to modify our compiler and toolchain to be able to link with this version. This took us weeks of work, reading documentation, testing, asking Microsoft, doing it step by step and finally arriving to the result. First, we had some mismatch between Debug and Release versions of the libraries when trying the validation. But as we were doing it manually, it was quite hard to understand what was going on, and the documentation was very scarce. And then, running the application with MSVCRT 110 was just crashing without meaningful messages or usable debug reports or crashes. When we asked Microsoft, some engineers told us that this could not possibly succeed, since the validation would not allow application compiled with 3rd party compilers to link with MSVCRT110. We did not want to believe them, since this would have killed the project. And, they were wrong. We did it, but this took us way more time than anything we had anticipated. The final work was shared and integrated in our toolchain, Mingw-W64. All other open source applications will benefit from that, from now on. COM RoAPI So, the final piece is composed of symbols that only have replacements using the WinRT APIs. Those WinRT APIs are a bit like extensions of Windows COM APIs. They work in a similar way, and are usable with methods similar to CoCreateInstance, named RoActivateInstance. However, they are not the same. People using Visual Studio, use a language named that has a bit of magic to hide all the details. So, the hardest part was done. What we are doing now is just rewriting the Microsoft WinRT headers and adapting the toolchain to munch those and call those symbols. So a great outcome is arriving! We have a bit of work still to go on rewriting the headers to call the new WinRT APIs, and kill the remaining 16 symbols. Some links in the article may not be viewable as you are using an AdBlocker.
