Hello Walter,

I think the problem is related with an old release. What you can do is to delete the sample compilation directory by yourself and then try by compiling/running again the application.

Please, tell me if that solve the issue.

Hello edunt,

May you wanted an answer about this. Taking a look at the project they appear very interesting and probably we can use it from App Builder just by adding the required Javascript file and by use the specified Javascript API. However, the technology works only in just a few browsers (may only Chrome?) and probably there is not easy to deploy in the server side, so maybe is not the time to implement right now (out of the box) in App Builder.

If you need help in order to use the required Javascript on App Builder don't hesitate to post here to try to help you.

Hello Walter,

Please, update your App Builder copy. I fix a bug in the MediaPlayer control and the MediaSetSource action which cause we can't play only with MP4 files even in browsers which support that. Now we can play only with MP4 files at least in Microsoft Edge, Internet Explorer, Firefox and Google Chrome, and probably more browsers which support MP4 files.

We can play only with other possible formats and of course continue adding various source files to the MediaPlayer.

Hello,

Me again... Finally I found certain bug in the MediaPlayer player Javascript code which causes the problem Walter! Even when we do not set other sources than MP4, App Builder add "empty" sources to the player, then the MP4 source is not taken by Firefox, for example. I am working in a solution and inform you when they are ready.

And sorry for the inconveniences Walter...

Hello again,

Following this page, MP4 are supported by Firefox, but, "MP4" means "MPEG 4 files with H264 video codec and AAC audio codec". So maybe you can assert the MP4 files uses such codecs, Walter. Maybe that's the "problem".

Hola pesadillo,

Ciertamente, echando un vistazo a alguno de los plugins enlazados arriba, se ven, si no complicados, sí extensos y complejos, por ejemplo, uno que me gustó que parece poder comunicarse con cualquier dispositivo cuenta con decenas de funciones Javascript que podemos usar. Creo que se trata de un componente más o menos especializado como para incluirlo en App Builder "out of the box".

Actualmente no hay una forma de crear plugins para App Builder, tal vez en el futuro. Pero, lo que sí es posible es extender el programa, es decir, nuestras aplicaciones, usando Javascript "puro", además del lenguaje de script de App Builder. En este punto conviene mencionar que los plugins de Apache Cordova ofrecen su API, precisamente, en Javascript.

De este modo, en efecto, es posible trabajar con plugins de Apache Cordova que no están "de serie" integrados en App Builder, así como otras posibles bibliotecas Javascript de posible interés. Hay varios ejemplos entre los incluidos con el programa: revisa los ejemplos Plugins, Magneto y QrCode, aunque creo recordar que hay alguno más.

Lo que debemos hacer para integrar un plugin para Cordova que no esté ya integrado en App Builder es indicar la ID del plugin en la casilla "Custom plugins" del diálogo de opciones de la aplicación, dentro de la pestaña "Cordova". Hecho esto, App Builder incluirá una referencia al plugin en el archivo "config.xml" para Apache Cordova, así como la llamada oportuna en los archivo "BAT" que se creen.

Después, tendremos que seguir el API del plugin en cuestión y averiguar cómo debemos usarla. En todo caso tendremos que hacerlo usando Javascript, cosa que podemos hacer en cualquier parte de nuestra aplicación, situando el código Javascript entre las acciones "StartJS" y "EndJS", por ejemplo, pero, también en forma de funciones de la aplicación, directamente, escritas en Javascript.

Ya sabes que puedes contactar conmigo y/o publicar en este foro si necesitas ayuda.

Hello fittachi,

The protocol behind HTML Compiler and that allow us to include files inside the executable that NEVER are extracted to the user PC, unfortunatelly, do not support "local" files for the video nor audio nor flash player components. The way you can shown a video in an HTML Compiler application is to place the video source online, in a remote server, or use some Youtube or other similar video service. We can use audio and video tags without problems if the source is placed remotelly.

On the other hand, we can also use some of the external Javascript functions that HTML Compiler provide to us. We can open an audio or video file, for example, and even open an specific executable (maybe a player) responsible to open the audio or video file we wanted. Take a look at the "LocalVideo" sample which is included with DecSoft's HTML Compiler.

Hello edunt,

Honestly, I don't have experience with HTML5 SIP, but sound interesting. I will take a look, but, remember that, if we can do something with Javascript, then we can integrate it in App Builder, even if they are not integrated by default. We can add Javascript files to our applications and use pure Javascript in any of the application, view and controls events.

Anyway I will take a look edunt.

Hello Walter,

Well. The problem is not, apparently, in the MediaPlayer control. Here in my system Firefox and Chrome can reproduce OGG (.ogv) files. On the other hand, MP4 files are taken from Internet Explorer, but not Firefox nor Chrome. Following the Mozilla documentation MP4 is not always supported and depends in the codecs:

The MP4 container format with the H.264 video codec and the AAC audio codec is natively supported by desktop/mobile Internet Explorer, Safari and Chrome, but Chromium and Opera do not support the format. IE and Chrome also support the MP3 audio codec in the MP4 container, but Safari does not. Firefox/Firefox for Android/Firefox OS supports the format in some cases, but only when a third-party decoder is available, and the device hardware can handle the profile used to encode the MP4.

The MPEG media formats are covered by patents, which are not freely licensed. All the necessary licenses can be bought from MPEG LA. Since H.264 is currently not a royalty free format, it is unfit for the open web platform, according to Mozilla [1, 2], Google [1, 2] and Opera. However, since royalty free formats are not supported by Internet Explorer and Safari, Mozilla has decided to support the format anyway, and Google never fulfilled their promise to remove support for it in Chrome.

Maybe is a pain, Walter, but probably we need to provide at least two different formats: OGG and MP4. Out there is a war about the format and we cannot rely just in one format, MP4 or other.

Hello edunt,

I think you no need to worry at all. Apache Cordova is an open source project used by lot of people and companies around the world: Adobe Phonegap, for example, is based in Apache Cordova. Not only this, but, App Builder is integrated with Apache Cordova in certain ways. For example, App Builder integrates various Apache Cordova plugins like Device, Camera, Barcode, etc., which allow us to play with the device's capabilities from our applications.

In other words, even when you try to use another similar environment, probably such environment uses Apache Cordova behind... and finally they are needed, because in other case the App Builder features which relies on Apache Cordova never can work. So please read the Apache Cordova CLI documentation and also how to setup the Android SDK: basically we need to play with the Android API level 22. Maybe other tools can be required, depending if some Apache Cordova plugin requires it, for example. In this case the plugin's documentation tell us what we need.

Hello edunt,

To generate APK files for Android or build for other platforms we recommend Apache Cordova CLI or Adobe Phonegap. App Builder prepare for you the appropiate application's config file for Apache Cordova CLI and Adobe Phonegap and Batch files for Apache Cordova CLI. I recoomend Apache Cordova CLI instead Phonegap for various reasons.

Installing Apache Cordova CLI can appear difficult at the first time (for example, we need to install the Android SDK too) but, once we get ready, build an App Builder for the Android platform is a question of seconds. You can found a mini-tutorial in the program help file, but, probably it's better to read information around internet.

For example, the Apache Cordova CLI documentation site can be a good start point.

Take a look at this video too:

If you have any question about the installation or have some doubts or need some help, just post here or contact me and I will try to help you edunt.

Hello edunt,

Thanks for your interest and kindly words. Currently, out of the box, we can use the MediaPlayer control to reproduce MP4 (MP3), 3GP, OGG and Webm file formats, however, the files must be placed in the app server. If our target are the browsers and our application resides in internet this is not a problem, because the media files are already placed in the server.

If we plain to build for the Android platform (using Apache Cordova), however, we need to take in count that our media files must be placed in a server, because the MediaPlayer can't work with local files, at least at this time. You can include your own Mediaplayer (but the local files "problem" probably persists) by using an HTML control.

You can use the HTML control (maybe an Iframe control too) to provide the MediaPlayer HTML. And then you can use some app, view or control event in order to place the required Javascript, if the MediaPlayer control requires it. However, the MediaPlayer control offered by App Builder is fully customizable, for example, you can provide your own controls and not the included by default.

Take a look at the VideoPlayer app sample included by App Builder (Menu -> File -> Samples) if you like.

Hope this information can help you in some manner edunt.

Hello Walter,

Apparently MP4 are supported for all major browsers, then, probably we can ommit the OGV source. Finally this is optionally and the browsers capable to play MP4 files just take the MP4 source.

Hola pesadillo,

Respecto de la primera cuestión, creo saber lo que está pasando. En efecto, la parte HTML de los controles no se "superpone", pero, la parte Javascript sí puede hacerlo, si los controles se llaman igual. De modo que, asegúrate de que los controles Iframes no tengan el mismo nombre. Tal vez esto pueda "corregirse" en el futuro, pero, no tengo muy claro cómo y de qué manera, o siquiera si debo hacerlo.

Respecto de la segunda cuestión, asegúrate de que el HTML que quieres mostrar en el IFrame está guardado usando la codificación UTF-8. Haciéndolo así no tendrás problemas para mostrar acentos y caracteres de otros idiomas. Acabo ahora mismo de actualizar App Builder para añadir el ejemplo "IFrames", que, muestra, precisamente, el uso de IFrames en dos vistas diferentes y con "acentos" y demás.

Actualiza tu copia de App Builder, pues, pesadillo.

Hola pesadillo,

Tal vez sea posible lo que necesitas usando algún plugin para Apache Cordova, por ejemplo, aquí unos cuantos que tocan el asunto:
