I am trying to create a plugin that leverages a live stream (rtmp) from Vevo. On playback of the stream, I get no video but I do get audio. I initially thought this was a hardware limitation of the AppleTV but I was able to reproduce the same problem on my Macbook Pro.
I've dumped a sample of the stream to a file.

I am not exactly sure what format of h.264 the AppleTV support or even how to find out the h.264 codec information on a file.
I was able to work around the problem by disabling hardware acceleration. This also works on the apple TV but it's a little choppy.
The error usually is of the nature
On the Apple TV2, the error line is
Debug Log of FAILURE when hardware acceleration (VDADecoder) is enabled on Mac OS X
