Windows Phone 7.5 Refresh Won’t Support All Video Files on Low RAM Devices

The limitations that Tango presents on low RAM devices has been well documented, but we’re still uncovering new things everyday. Now we’re discovering that the Lumia 610, presumably along with other low RAM devices, will have less video playback capabilities. The text below is from a guide created by Nokia for developers.

Formats that are not supported on all Windows Phones — such as FLAC, RMVB, and OGG — will fail to play on 7x27a-powered phones.

Video in a supported format but encoded in a codec not supported with hardware acceleration or at higher bitrates or resolutions than the Windows Phone baseline, may either fail to playback or be rendered in software. If software rendering occurs playback will be poor — jumpy and choppy.

For example, a video using the VC1 codec Advanced or Main profiles may play through software rendering, instead of hardware acceleration, but if the encoded bitrate is too high it will fail.

7x27a-powered phones impose limitations on the video they can play. These limitations have been implemented to account for the lower processing capacity and memory of these phones. However, by re-encoding your video and making use of the techniques outlined in this article you can preserve your apps UX and continue to offer your users a rich video experience.

This is the price you pay for paying a low price. In other words, Tango devices will sacrifice some features, but you’ll pay less for them. The question you’ll have to ask yourself is is it worth it?
