DSLR no preview on Android

[laheller]

Hi @artyom-beilis

I am testing the OpenLiveStacker Beta 23 Android application using my Samsung Galaxy S20+ smartphone and Canon EOS 1300D camera. When I just compare the app UI behaviour if I use my ZWO ASI120MC-S camera instead of Canon, I can see live preview on the UI when I tap on the Stream button. But in case of Canon camera when I tap on Stream button, there is no preview, the app only starts some lens autofocus and display a message (see the attached screenshot below). Also when I try to select the camera from list, I would expect to see its name (e.g. Canon EOS 1300D) instead of just "Camera". See some attached screenshots, hope they helps.

BR,

Ladislav

It's already in manual mode (via knob) and manual focus (via switch on the lens). OLS immediately starts capturing images when I tap on Stream button. I guess this is the expected behavior.

But I am talking about a simple Canon EOS viewfinder liveview which I expect to appear, once the camera is ready to provide it, without any image capturing and saving it to SD card. Is there such function or this is not implemented?

Also it's not clear for me, what are the functions of the checkboxes Auto Str. and View Finder ? What does their checked and unckecked state mean? I tried all 4 possible combinations but did not see any difference.

AutoStretch just makes sure that image isn't too dark. It is ols post-processing

Viewfinder when checked brings the mirror up so it doesn't move each time image capture is triggered. It is dslr specific

Now first time you connect to camera it does test capture to see supported formats and sizes (if raw is enabled etc).

When you press stream it start capturing images and streaming them to the ols screen.

Note: images aren't saved at sd card or camera. They are deleted after downloading

OK, now the meaning of settings is clear. Also it is clear, how it works in case of DSLR: Once tap on Stream button, it immediately start to take series of images using the configured ISO, shutter speed, etc.

But in my case the camera (Canon EOS 1300D) does NOT support the mirror lockup function, so when before Stream I enable the Viewfinder checkbox, I hear the "mirror up" noise from camera body and its display will be turned off. When the Streaming starts, the mirror will be alternating once up once down when taking photos.

According to the OLS documentation the streaming function is NOT the livestacking itself, or am I wrong? It's just a camera picture preview. If so, then I would expect to bring camera into kind of "video mode" and display the video frames in OLS streaming mode.

You are correct. When live streaming is active you can start/stop live stacking

Because you configure everything in stream mode so you want it to be same as actual stacking
