The pyramid feature extractor downsamples the input six times as follows.
Lines 78 to 130 in b638427
The input thus has to be at least 128x128 such that the last layer is 2x2 (it cannot be 1x1 in practice as it would try to compute flow where there is none). Such a small input probably deviates quite a bit from what the network was trained on though, so I would recommend not going below 256x256 instead.
