Our team is developing a WP7 and WP8 app using SMFPlayer v2.7 and we have prepared a set of 480p smooth streaming content for testing.
All content can be playback on WP8 perfectly. However some of the content will display a grey/rainbow color screen on WP7.
Is the problem due to
- hardware limitation
- SMFPlayer framework limitation
- unsupported smooth streaming content profile (VC-1, 480p, 1.5Mbps/1Mbps/800kbps bitrates)
