Sony A5100 live view problem

[jbonnett92]

Hi,
I can't seem to get live view to work:

It doesn't error until I visit the url http://localhost:8081/feed1.ffm.

does it capture a movie without this pipe?
or single previews?

[jbonnett92]

@msmeissn No it doesn't, it just times out

[jbonnett92]

gphoto2 --camera="Sony Alpha-A5100 (Control)" --capture-preview --debug --debug-logfile=First.txt First.txt

The screen had the live preview although I did not get any preview on the computer.
Without disconnecting the camera or turning it off I ran the same command and got a different error:

gphoto2 --camera="Sony Alpha-A5100 (Control)" --capture-preview --debug --debug-logfile=Second.txt Second.txt

And then I did the same with --capture-movie:

gphoto2 --camera="Sony Alpha-A5100 (Control)" --capture-movie --debug --debug-logfile=Third.txt Third.txt

And

gphoto2 --camera="Sony Alpha-A5100 (Control)" --capture-movie --debug --debug-logfile=Fourth.txt Fourth.txt

Sorry for losing track of this issue.

The getobject call is emitted and seems to never return, either it confused or crashed parts of the camera firmware.

I googled a bit and there is one report of using updated firmware making it better, but all others seem to imply there is no liveview on the 5100

[msmeissn]

so you can try to get the latest firmware and see if that brings help, but otherwise I think we are out of luck regarding liveview.

a friend of mine runs: http://www.storch-bleckmar.de/ wth a 5100, he has the firmware updated

[jbonnett92]

Sorry I don't actually have the A5100 anymore, I have the A6300.

[msmeissn]

ah ok. for this it works I assume? ;)

[jbonnett92]

Not sure I'll give it a try later :)

[msmeissn]

ok! open a new ticket if it does not work :)
