Hello,

I am trying to calculate Sansung Galaxy i9000 FPS, but do something wrong.
According to the WURFL repository Sansung Galaxy i9000 has "streaming_vcodec_h264_bp" = 1.2.

I use Level table from the wikipedia http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels
and find next values for the level 1.2:
Max macro blocks per second: 6000

The Max macro blocks per frame formula is : Max macro blocks per frame = (ScreenPixelHeigh/16)*(ScreenPixelWeight/16)
Max macro blocks per frame for Samsung Galaxy i9000 is: (480/16) * (800/16) = 1500

The FPS formula calculation is : FRS = Max macroblocks per second / Max macroblocks per frame
FPS for Samsung Galaxy i9000 is: 6000/1500 = 4.
But according to the WURFL documentation the FPS for the profile 1.2 is 30 fps.
See http://wurfl.sourceforge.net/help_doc.php The table TABLE 1(H.264 Levels). Level 1.2.

The official Samsung site declares that i9000 supports 30 fps.

There is big difference between 4 and 30 fps. Who can help me and tell where is an error?

Thanks.
Alex.

Hi Alex, I'm not familiar with how the FPS figures are calculated, but if you do find that the streaming_vcodec_h264_bp is not accurate in the WURFL, I can certainly correct it.
