This week we reviewed the Amazon FirePhone, the one and only flagship mobile device from Amazon. While there was a lot of hype around this phone, it quickly fizzled and Amazon has since dropped the phone price to a whopping $0.99. Not a great sign for the long term success of the device. Our video playback testing reflected the market sentiment for the FirePhone as it was lacking in several areas. The biggest shortcoming was in the lack of support for HTTP-Live-Streaming. All of our test HLS streams failed to play on this device, both through the default media player as well as third-party players. This was surprising due to the fact that the FirePhone is running a variation of Android 4.2 Jellybean which offers limited support for the HLS. In addition, we had great trouble displaying closed captions with the FirePhone. Despite the major shortcomings of playback on this device, it does in fact play MP4s with ease. We recommend serving an MP4 with 0x480 dimensions and a 600k bitrate. This is a lowest common denominator to account for various bandwidth scenarios.
