Live Network Preview on Canon Rebel T6 #492

Open petabyt opened 4 years ago

petabyt commented 4 years ago

I am trying to get my Canon Rebel T6 to work over my network. I used the smartphone setting to connect to my PC, and it works mostly. I can take pictures, but I can't use the live preview mode. It gives me: Unable to capture live preview: (null)

I am doing this via Entangle, so here's some more info:

Entangle version: 2.0

libgphoto2 version: 2.5.22-3

Camera model: Canon EOS Rebel T6

I found this archive, but it didn't help me. https://www.mail-archive.com/entangle-devel@gna.org/msg00100.html

I was redirected here by a Gitlab issue, here: https://gitlab.com/entangle/entangle/-/issues/43

He pointed out some errors, then redirected me here.

Thanks.

I tried running this command: gphoto2 --debug --debug-logfile=my-logfile.txt --port ptpip:192.168.1.14 --capture-image and got a lot of errors, I'll upload the log file if needed.

I guess liveview works over USB?

A debuglogfile would be good.

I guess liveview works over USB? Yes, it does.

A debuglogfile would be good. Ok, I will get that soon.

Really sorry for late reply, I have been busy. http://petabyte.heb12.com/filedump/my-logfile.txt

I tried another command, it looks to take longer to connect there. gphoto2 --debug --debug-logfile=capturepreview.txt --port ptpip:192.168.1.2 --capture-preview http://petabyte.heb12.com/filedump/capturepreview.txt

And Entangle can connect to my camera, take pictures, and return them via a network connection.

msmeissn commented 4 years ago

can you try if inserting an SD card helps?

petabyt commented 4 years ago

I have had one in. It won't do any connecting without one.

msmeissn commented 4 years ago

Hmm. the camera sadly does not tell us why its busy :( We might not have drained enough events , but this is also unlikely.

Can you add an additional --wait-event=1s before the --capture-preview ?

petabyt commented 4 years ago

It worked a little bit more, but it gives *** Error (-1: 'Unspecified error') *** and *** Error (-110: 'I/O in progress') ***.

gphoto2 --debug --debug-logfile=capturepreview.txt --port ptpip:192.168.1.2 --wait-event=1s --capture-preview http://petabyte.heb12.com/filedump/capturepreview1.txt

I also tried it with 5 seconds. gphoto2 --debug --debug-logfile=capturepreview5.txt --port ptpip:192.168.1.2 --wait-event=5s --capture-preview http://petabyte.heb12.com/filedump/capturepreview5.txt
