Sony PTP Extension support about sequoia-ptpy HOT 9 OPEN

Hi @WIsbrecht ,

Sorry for the delay. It seems the camera itself does not respond to the request.
I will have a look at Sony's extension to see if there is something essential missing.

Currently no extension is implemented in PTPy for Sony cameras.

From 2d9e551, there is an ongoing implementation of the Sony extension.

Hey,

i did a quick single step debug session and found that the timeout error occurs even before

from sequoia-ptpy.

Hi,

The write transaction to get the camera details is timing out. It is ignored the first time, but the second time around it fails.

I've reduced the maximum transfer size in the latest master.
Could you give it a go?

Also, have you enabled the remote control in the options in the camera?

Hey,

just tried the latest master. No dice.
I can control the camera with gphoto2 though.
Could it be the udev rules which come with gphoto? Is there a way to actually make sure that ptpy can talk to my camera?

Usually all it takes is to disable automatic volume mounting (or manually ejecting the camera volume before running your script).
But by the looks of it, it is not the camera being busy that fails but rather that it times out.

Hey,

so it seems as though automatic volume mounting is already disabled, hence gphoto2 is able to control the camera.
How would you proceed with debugging this further? Would be nice if someone with another Sony camera could give ptpy a try and report back.

Hi @WIsbrecht ,

I have a couple of Sony cameras at hand for testing.
There should be no issue in instantiating the camera.
Please try with the latest master and ensure the camera is not mounted.

FYI, the Ubuntu interface uses libgphoto2 so it might handle handing the camera back and forth. This is not the case for PTPy, it is fully independent.

A full implementation of the Sony extension is on the works.

Hi,
just an update regarding Sony camera support.
I have setup a raspberry pi 4 and my Sony a6000 camera.
I tried the latest master branch of ptpy (28 December 2020).

Catching the device information with the example script print_device_info.py works fine:

However, i tried the trigger.py and the download_all_images.py scripts and got usb.core.USBError: [Errno 32] Pipe errors.
The debug output for trigger.py is available here:

The debug output for download_all_images.py is available here:
https://pastebin.com/7g5GMyTz

I would love to use PTPy for my Sony camera project instead of gphoto2.
What could be the reasons for the errors?
