Error showing value of type CameraList #19

Closed IanButterworth closed 5 years ago

IanButterworth commented 5 years ago

I'm getting this on master on ubuntu 18.04.

The camera that's attached (grasshopper 3) can be detected by spinview

It looks like this broke in https://github.com/samuelpowell/Spinnaker.jl/commit/0f032fcb028113462b6ea5a328855a29050b12d8

samuelpowell commented 5 years ago

Hmmmm okay will look into it

IanButterworth commented 5 years ago

I've not got any further with this. You got any hunches?

samuelpowell commented 5 years ago

@ianshmean I cannot reproduce:

julia> camlist = CameraList()
CameraList with 1 enumerated devices:
ID  Serial No.  Description
0   XXXXXXXX    FLIR Blackfly S BFS-U3-16S2M

Are you definitely using the latest released version of Spinnaker.jl, or master?

samuelpowell commented 5 years ago

@ianshmean what happens if you try using examples/enumeration.jl, this script only uses the low level Spinnaker library calls and is essentially a implementation of the C level enumeration demonstration.

IanButterworth commented 5 years ago

examples/wrapper/enumeration.jl gives:

julia> include(joinpath(dirname(pathof(Spinnaker)),"..","examples/wrapper/enumeration.jl"))

Okay I'll try and see what's different between the two...

IanButterworth commented 5 years ago

For reference, rolling back to https://github.com/samuelpowell/Spinnaker.jl/commit/7585748e3d87b08ec435f4a54f9786f662444176 works and gives:

julia> CameraList()

samuelpowell commented 5 years ago

@ianshmean what happens if get your camera and do:

get(SpinEnumNode(cam, "ChunkSelector"))

IanButterworth commented 5 years ago

@samuelpowell I think you're in the right area.. my camera doesn't seem to support the Timestamp chunk, and maybe has renamed FrameID? https://github.com/samuelpowell/Spinnaker.jl/blob/71dcd901c63addc7871377162ee0c335241e41d8/src/Camera.jl#L40-L43

samuelpowell commented 5 years ago

Yes.... try PR #27

IanButterworth commented 5 years ago

Great. 

julia> camlist = CameraList()
CameraList with 1 enumerated devices:
ID  Serial No.  Description
┌ Warning: Unable to enable FrameID chunk, image metadata may be incorrect

It's not very helpful that they've got multiple names for the frame counter. Perhaps a try with alternatives approach??

samuelpowell commented 5 years ago

I will open an issue to fix it, PR welcome. Timestamp not critical but frame ID useful.

IanButterworth commented 5 years ago

Oddly I'm not getting an error for Timestamp.. perhaps it's a hidden chunk option

samuelpowell commented 5 years ago

Partial fix in #27, pending resolution in #28
