Wrong UV in h264 video stream by cudaEncode


I use cudaEncode in toolkit v5 to encode YV12 sequences into h264 video streams on my Win7 notebook with Quadro FX 880M GPU, I found the UV component is not correctly encoded by cudaEncode when I playback the encoded h264 video streams.

Does anyone encountered this issue before or someone can give me a hint on this issue ?

Thanks in advance.
