Stream overflow trying to get higher resolution images #19

Closed hendrixjl closed 8 years ago

hendrixjl commented 8 years ago

First: Great software! I am trying to get higher resolutions than what are the actual defaults config.py (1024 x 768). I'm using that new raspberry pi camera (V2.1). I'm getting the following errors:

++++++++++++++++++++++++++++++++++ pi-timolo.py - Exiting Program +++++++++++++++++++++++++++++++++++

Traceback (most recent call last): File "pi-timolo.py", line 689, in Main() File "pi-timolo.py", line 603, in Main data1 = getStreamImage(False) File "pi-timolo.py", line 458, in getStreamImage camera.capture(stream, format='rgb') File "/usr/lib/python2.7/dist-packages/picamera/camera.py", line 1577, in capture encoder.close() File "/usr/lib/python2.7/dist-packages/picamera/encoders.py", line 893, in close self.stop() File "/usr/lib/python2.7/dist-packages/picamera/encoders.py", line 881, in stop self._close_output() File "/usr/lib/python2.7/dist-packages/picamera/encoders.py", line 795, in _close_output output.flush() File "/usr/lib/python2.7/dist-packages/picamera/array.py", line 285, in flush self.array = bytes_to_rgb(self.getvalue(), self.size or self.camera.resolution) File "/usr/lib/python2.7/dist-packages/picamera/array.py", line 174, in bytes_to_rgb 'Incorrect buffer length for resolution %dx%d' % (width, height)) picamera.exc.PiCameraValueError: Incorrect buffer length for resolution 100x75

Are there other parameters I should change to make this work? Thanks!

The pi-camera python library internally compares the camera output buffer with the specified image size to see if they match. If the two do not match then the above error is raised. In my experience the problem is usually due to a camera cable or Raspbian firmware issue. I have not yet tested things with the new 8mb camera module although I have received one. It is possible there is an issue between the camera hardware and the pi-camera library.

You can try reseating the cable and doing a raspbian firmware update that is documented in the github instructions.

I did a firmware update and that seems to have done it. Thanks!
