TestScaler::ComputeAvgSequencePSNR is currently a complex NOP, that always returns kPerfectPSNR. Two frames are read from files into arrays, and then converted into I420VideoFrames. However, the incorrect function ConvertFromI420 is used instead of ConvertToI420, resulting in two empty I420VideoFrames. I420PSNR on empty frames returns kPerfectPSNR. This CL replaces ConvertFromI420 with ConvertToI420 and actually measures the PSNR. Unfortunately, some tests do not pass when we use the real psnr. The tests that fail are the ones that scale back and forth to a different aspect ratio. webrtc::Scaler has been changed to preserve aspect ratio, and this means that we will end up with a cropped frame if scale and rescale to a different target aspect ratio. I simply removed those tests to make it pass. Having some working tests instead of a lot of dummy tests seems like a win.
