Re: [gphoto-devel] Leica SL Image Capture Not Supported

Thank you for your contributions, Marcus. Attached are the summary.log and summary.txt files you asked for.

By the way, I think you may have mistyped the command. It seems to be:

```

gphoto2 --summary --debug --debug-logfile=summary.log > summary.txt

```

Which uses `—debug` instead of `—debuginfo

summary.log
Description: Binary data

These are the steps that I did:

I git cloned the libgphoto2 repository on my MacBook Pro 15” Retina 2018: https://github.com/gphoto/libgphoto2.
I followed instructions in the INSTALL file in the repo: https://github.com/gphoto/libgphoto2/blob/master/INSTALL.
I saw a lot of logs coming out on the `make -j6` step (I have 6 CPU cores). But no errors (at least it ran to completion)
Then I ran `make install`.
Then I navigated to my root directory and typed in the command you provided.

Let me know if this has what you need. I hope this ran the updated git code, not whatever I had previously installed when I had installed gphoto2 before.

Hi,

I see the the Leica SL is listed under supported cameras (http://www.gphoto.org/proj/libgphoto2/support.php <http://www.gphoto.org/proj/libgphoto2/support.php>) but not under the remote controlling cameras page (http://www.gphoto.org/doc/remote/ <http://www.gphoto.org/doc/remote/>).

On my MacBook Pro 15” Retina 2018 have confirmed that I am able to run `gphoto2 —capture-image` and the camera takes an image. But I am unable to run `gphoto2 —capture-preview`. My goal is to be able to stream images.

This is the debug output when I try to capture preview. See attached file.

However, I see that the Leica Image Capture 3.7 app does support live image streams (and very quickly with around 0.1 second latency). See screenshot of this working. Do you have a sense of what underlying mechanism Leica Image Shuttle might be using to get the images to the Mac? It seems to me that there is definitely PTP being used since I see PTPCamera open as a process when Leica Image Capture 3.7 runs.

Hi,

I spent some time looking over the debugtrace, and also reverse enginering the LightRoom driver
and now the Image Shuttle executable...

Currently we do not know how the preview is being streamed to the machine.

It looks a bit like it uses PTP 1.1 "Streams", which we currently do not yet implement as we had no
other camera using it so far.

I have now added some PTP stream debugging code and Leica specific open and close session commands to libgphoto2
master already in preparation, if you want to try it.

Once built, run:
gphoto2 --summary --debuginfo --debug-logfile=summary.log > summary.txt

and attach both summary.log and summary.txt.

Ciao, Marcus
