Shall we hold on H.264 > mainline for now ? hmm, reading the TRM the VDPU121 claims to support: - VP8 - VC1 - MPEG-1,2,4 - H.263 - JPEG So at least the TRM doesn't list h.264 as supported at all on VDPU121 . Not sure what is up with that or is Rockchip also just suggesting that h.264 should be in the VDPU381 [where h.264 is listed as featured] ? Heiko
