Comment (by andrewc):
bovine: thanks for the heads up. I didn't realise that digest auth was
being used (and that zoneminder doesn't support it)! I sidetracked the
issue, by using the 'ffmpeg' option in zoneminder to grab the stream.
> Does playing a captured file work for this model?
cehoyos, my earlier description of 'seems to work ok' wasn't very
specific. Let me elaborate: It seems to be working fine in zoneminder. I
can see the stream in my webbrowser, although there are the occasional
visual glitches (every 5 or 10 minutes, somewhat random), which look like
they resolve when a keyframe comes along, so I suspect the decoding is not
100% reliable. I think the glitches are more prevalent around areas of
motion and when there is more motion being captured.
I tried dumping the stream again (and again... and again) and everytime
the result was a slightly different set of errors.
Run 1: I cancelled after a 10-20 seconds:

NB, ''/tmp/fishburn.avi'' was not created! (I'm not quite sure why, I
would have expected at least an empty file) and this was the first time I
received the _corrupted macroblock_ error with this cam.

So it looks like the same issue as the Fisheye cam. Perhaps the issue is
not as pronounced in zoneminder because of differences in resolution,
framerate etc.
