We have some basic properties in DeviceAtlas that describe the ability of a device and its software to playback video in various formats (MPEG4, 3GPP, H.263, AMR, AAC, etc), but we think it would be interesting to have some more and we think that streaming is another important topic that we are not yet covering.
In order to add new properties in DeviceAtlas we want to investigate how this could be useful to our users and what is needed to make it useful. Do you need to know about more video codecs? more audio codecs? Bitrate?
Also, how can we build good tests for mobile devices? We have TA-DA available and we think it will be the best way to create solid tests that we can run against hundreds if not thousands of devices and see how it works. Not to mention that TA-DA should also be a reference when you are developing or testing your own applications and services. So what would you like to see in TA-DA for video testing?
