Having to deal with a very busy summer, development for AVChat has been slower than usual, but we managed to allocate enough time in order to release a new build and as always we’ve integrated most of the new requests along with some compelling new features.

Real-Time Text Chat Translation

We have implemented a mechanism that permits AVChat to detect the language the browser is setup for. Based on this and using Google’s Translate API you can now translate on the fly messages from another language, from a user that has the browser setup in french for example, to your preferred language, assuming as well that your browser is setup in your particular language.

A small translate link will appear on the side of the text message, pressing it will show the translation for that particular message in a smaller grey font beneath the original text, as shown in the images below:

In order for this feature to work, an active Google API must be provided in the new setting googleAPIkey found in avc_settings. The key must also be enabled from the Google developers console for the Google Translate API.

Individualized Video-Stream Sizes

We have modified the behavior of the mechanism. The way it functioned before was limiting the viewers to a particular default display width and height of the video streams they were watching, that was preset in the audio-video profile XML’s through othersDisplayWidth and othersDisplayHeight.  These 2 settings have now been removed.

The way it works now, is that the end viewer will see by the default the video-stream in the broadcaster’s resolution. So if the broadcaster is transmitting at a 640×480 resolution the viewer’s window will have the appropriate size.  You now might say, ‘but it will fill up the whole screen if the broadcaster streams in HD’ for example. To fix this possible issue, a new setting has been added in the audio-video profiles: othersDisplayScale. By default is set to 1 for a 1:1 ratio, but it can be decreased or increased as needed. Here’s how different sizes are represented:
