Hello all

a late Discovery of this message.
actually this happened either for the sony but also for the oly mirrorless. This "repetition" of a flaw/bug is triggering a flag in my mind. Indeed can we assess that this is something missing/wrong in the gphoto lib? actually i think that this missing widget is also impacting other tools like darktable and even the concurrent of indi (indigo) either by preventing a correct function or behaving very slowly until timeout.
Should we decalre a bug in the gphoto list ?

Hi

tested by a friend of mine. working flawlessly.
by the way is it in the 1.8.0 release?

Yes. I have done the test on olympus in start and stop preview, but maybe it is not the most logical "place". And maybe the test on olympus only is too "restrictive".
Actually, since the camera do not have mirror to be locked it do not have the corresponding widget in gphoto . hence gphoto do not find it. but the current (without this mod) gphoto_driver in indi check for this viewfinder widget (and need it) to work properly. It may be also the case for other 4/3rd mirrorless DSLR (pentax/lumix) dunno.

Hi all, Jasem,

I attached the modified file with test on brand for the viewfinder.
I am able to capture up to 1280x960 but full hd (16/9)should be doable, though have not been able to get it (will cut top and bottom of he image)

HiJAsem

HAve installed all the reuired things for compilation.
i have first verified that the original recompiled was working fine. Everything went ok
However things are more complex since gp_capture and gp_capture_preview do not take the same args.
gp_capture ask for a path while gp_capture_preview ask for a file.
So things are more complex here and i feel unable to dig into (my feeling is it requires a "deep" mod of the code)
However the good news is that, getting back to gp_capture_preview but forcing returning GP_OK in the gphoto_start_preview and gphoto_stop_preview i am able to capture a SER file full of images...
Still have to try the direct stremaing in kstars..but i think it should work ok.

Hi Jasem
Can try to do so...but i need first to install a compile environnement...but let's try.
What about the message about mirror not going up (it is in the viewfinder widget call if my understanding iscorrect should i comment the if l to test?)
Note that it's long time ago i put my hand in code...hope to be not too rusted

Hello,
Finally got it working by doing a full and "clean" update.
However the streaming mode (and the preview too)is not working (indi always claiming viewfinder not found, can't force mirror to go up, failed to start streaming).
I discovered by using gphoto2 cli (and also looking at the indi code..though not a very good programmer) that the command used for preview and streaming in indi is using gphoto_capture_preview. However, the capture preview looks to be really buggy with this DSLR (only able to get one jpg image, after that need to unplug and replug the camera if we want to reuse the command)
However the capture-movie option works ok (that is gphoto_camera_capture with GP_CAPTURE_MOVIE ) (mjpg stream type)
Hpe this help

HEllo,
quite new on this forum but using indi since few years already. I recently changed my Nikon D90 DSLR for an olympus em5 mk2.
i was quiet comfortable when using the nikon gphoto (liveview/video/bulb capture with rs232shutter)buti amreally struggling at having things working with the oly.
i first used the standard gphoto module to try to connect to the oly. the connection looks to be ok but no success in triggering a capture (bulb or sub second))(driver complaining about the shutter device (set to empty)not present.
I also tried to get the preview/liveview/or video but no sucess either.
I then tried the pentax gphoto module. the oly connect (and is detected properly as oly). The exposure is working ok (at least subsecond, not tried bulb). However live video or preview is not working at all.
gphoto is the indi one (with the bulb problem correction).
Currently not at home,but will try toget somedebug logsfromgphoto at least
Thanks forhelpor advices.
