** Info

1. using /cam.cgi?mode=accctrl&type=req_acc authorization request will report error
2. to use the lumix sync app's authorization method, two encryption parameters are required. If the parameters are wrong, the camera will always be stuck in the loading process of the connection
3. the two encrypted parameters of the req_acc_e authorization method will be updated every time you connect

/cam.cgi?mode=accctrl&type=req_acc_g
/cam.cgi?mode=accctrl&type=req_acc_e&value=...&value2=...

examples:

/cam.cgi?mode=accctrl&type=req_acc_e&
value=7171bb087476c6087474cf117474d20c7c68cf0c6974cf0c7475cd0c7775cf0c7571b978

/cam.cgi?mode=accctrl&type=req_acc_e&
value=6b11d81a6e16a51a6e14ac036e14b11e6608ac1e7314ac1e6e15ae1e6d15ac1e6f11da6a

Interesting. likely be harder to reverse engineer how they generate those.

[msmeissn]

i am not aware of this new method and how it works

req_acc_g is also there?

[tangbl93]

@msmeissn req_acc_g don't require parameters。 i guess req_acc_g is similar to the activation input, and req_acc_e is similar to submit the passcode。

Is there any reason to support this encrypted HTTP based one, instead of PTP?

gphoto2 --capture-image runs sucessfully on my S5M2, but it takes 30s+ to return to the new file location & command prompt (it seems to take much longer if camera SD card has a lot of files on it).

when I run gphoto2 --shell --debug --debug-loglevel debug <<< capture-image, it looks like the biggest hang is here:

NOTE, the camera is NOT a GH5, but seems to be assuming the GH5 has the most similar driver?

I'm very new to gphoto2 but would love to get this camera running (faster) so please let me know if I can help!
