Processor suggestion for H.264 video decoding

Hi all,

I want to design a board with the following inputs and outputs:

Input:

• USB port (to read 1920x1080 h.264 mp4 video files from flash memory)
• microSD card (to boot OS, like linux, or Android)
• LAN (to connect to internet)

Output:

• 24-bit RGB data (to give to an LVDS Serializer/Transmitter IC which connects to 40 inch LCD panels)

I know that AM57xx family is capable of doing this, but they are not cheap!

Would you suggest a cheaper solution?
