Mike Boers is trying to support PyAV (python Audio Video editing/merging/converting library based on FFMPEG) . The current master fails 6 of the unit tests: - 4 of them are in __repr__ methods, and seem to be due to basic difference in module name handling. - 1 is with Numpy; I expect there was an API change there. - 2 is with memoryviews; I suspect there are marginal differences in that implementation. https://github.com/mikeboers/PyAV/issues/130 I am forwarding it here. Thanks Phyo.
