Scripting Corner / Re: ISO strangeness

Using latest Lua fix on 5D3 123.

Shutter and aperture all OK.

Reading ISO is OK.

Just tried running the API test script and got error "Not enough memory" ?

Scripting Corner / Re: ISO strangeness

Last time I've checked, it used to work:

https://foss.heptapod.net/magic-lantern/magic-lantern/-/blob/branch/lua_fix/scripts/api_test.lua#L785

Code: [Select]

            local apex = math.random(5*100,10*100)/100
            camera.iso.apex = apex

Scripting Corner / ISO strangeness

« Last post by garry23 on January 17, 2021, 12:11:21 PM »

I've convinced myself that setting ISO values via Lua 'may' be broken.

I can use camera.iso.apex or camera.iso.value etc to read, eg x = camera.iso.apex; but if I use something like camera.iso.apex = 10 I get 'failed stack traceback' error.

Has anyone else come across this?

Feature Requests / Re: independent auto-upload

I've made some progress towards my goal: gphoto2 (hints from here) works if you use the function "Remote control  (EOS Utility)", rather than "Connect to smartphone".

I can list and download photos. The speed is 1.9MB/s in optimal conditions, so roughly 14 seconds to transfer a raw+jpg. This is far below the supported 802.11n standard (similar speed reportedhere), so that's a very limiting factor.

Functional, but not yet great.

Pull: gphoto2 via wireless.

Current status: networking functions were documented several years ago, but no such functionality implemented in ML yet.
https://www.magiclantern.fm/forum/index.php?topic=11053.0

Otherwise, the functionality should be doable, but has to be built from scratch - possibly with reusing some existing libraries. No 6D here, so... can't help much.

I'm looking for wireless image.canon functionality, without the canon part. (I'm one of those guys I guess). Or wireless tethering without windows. My target is a 6D mk1.

Is this a pipe dream? Is there a pre-existing solution, or building blocks?

Can I write a lua script so the camera connects to a wifi network and starts uploading to an endpoint of my choosing, preferably in an easy protocol like ftp/sftp/http/...? (I'm new to lua but not other scripting languages, but it would still be an investment)

Or Is there a way to do the inverse and have an android or linux machine pull images out of the camera over wifi?

FIO_SeekSkipFile: should be testable in QEMU, with a large SD image and the test code from selftest.mo. That test will create a large file (2GB) and seek within that file.

There are two versions in Canon firmware: one that accepts 32 bits for the position and another one that accepts 64 bits. They are not interchangeable at binary level.

Sorry, I was trying to be specific to the opacity adjustment approach and using pairwise summation via (a+b)/2.

I'll stop posting on this now
