UcaCamera bugfixes #84

Closed tfarago closed 11 years ago

These problems are actually located in libuca and as such does not really hold back release of v0.4. I'll re-assign the issue to v0.5.

I tested the many frames mode again and it seemed OK, well I didn't see anything except dark noise because the lens is gone now, but at least recorded_frames was consistent with the number of frames I got and the grabbing stopped, so points 1 and 3 from the initial list are hopefully history. many frames is addressed in PR #102 from Concert side.

I found another issue, camera.uca.props.storage_mode = whatever has no effect. I hope we will get the live preview once this is fixed. Just to remind us about the live preview requirements, on the Dimax the storage mode must be set to recorder mode. From what I could see the grabbing function looks OK, maybe we should check for the error from pco_request_image, which is implemented on line 1883 here.

Ok let me see on Monday or during the weekend. The camera is still attached on and running?

tfarago commented 11 years ago

So far, but they will need to disconnect it on Monday or Tuesday, I will inform you on Monday.

I am getting segmentation fault here when I use a user who is not a member of users and video, I don't know to what I need to belong actually. I think we had this issue once already, we should have a look again and fix it for good.

matze commented 11 years ago

I may have fixed the segfault but not the general problem that users have to be in certain groups to gain access to specific hardware. At the moment the camera is gone, right? I now don't get segfaults with uca-camera-control but no CameraLink ports could not be activated either.

tfarago commented 11 years ago

I still have the segfault. Can you tell me to which group I need to belong to? I will try to add the user there if it's possible. I am guessing video?

matze commented 11 years ago

That change is not installed there yet. In any case, I don't know which group is necessary, this is the situation for me:

$ cat /etc/group | grep vogelgesang
video:x:33:csa,anzt,gdm,vogelgesang,werchner,ashkarin,rshkarin,guest,farago

I fixed setting the storage mode.

@sensej: Could you open a new issue if you encounter a problem next time? These big meta issues with their non-descriptive titles are getting a bit out of hand.

tfarago commented 11 years ago

Live preview seems to work with dimax. Closing, will recheck everything and will write separate tickets if I find any bugs.
