No, it also supports ARMv4/5. The assembly is not as complete for those 
chips (particularly for the encoder) as it is for ARMv6 or NEON, but 
Huffman decoding, basic motion compensation (but not the encoder's 
motion search), the iDCT, and the loop filter should all be accelerated. 
The theorarm-merge-branch did not include assembly for the encoder, either.
