[Sndobj-devel] Problem with PushIn and Numpy array from h5py
|
From: Luigi C. <lui...@ya...> - 2009-06-30 11:46:38
|
i use python-sndobj.
i created a sndthread with a callback function that pushes in a slice from a numpy array in sndobj; the numpy array is a view from an h5py file (created using h5py library facilities)
def __process_callback(self, channels):
if self.stream.pos_ptr < stop:
for i in range(channels): self.channels[i].PushIn(self.stream.audiodata.get_slice(self.stream.pos_ptr, self.stream.pos_ptr + 256, i) * 32768)
self.stream.pos_ptr += 256
i think that the problem is in h5py + sndthread, because also without pushin function in the callback, application crashes.
if i use same array in a qthread or in a python thread it works without problems;
this is the bt:
