Lua Scripting (lua.mo)

[a1ex]

Switched to an EF lens with the EF to EF-M adapter and finally got through the tests.

That's right, I've tested with an EF lens, and all other continuous AF features turned off. Don't have any EF-M lenses yet; the 22mm STM seems to be the only half-decent one (for what I'd use), but that's probably not the trickiest lens for ML. On full frame, that lens is equivalent to 35mm f/3.2 - not *that* tempting in low light (but then, you can't compare its size with a Samyang 35mm/1.4).

If the EF-M lenses attempt to move, at least a tiny bit, my best guess is that ML might be checking the wrong status bits while waiting for a confirmation. If you comment out the waiting functions from lens_focus(), it might work better. For example, for a quick test, one could use prop_request_change instead of prop_request_change_wait, comment out lens_focus_wait(), and set a larger delay in the focus settings menu. If that works, we need to find out how to tell when the AF motion was finished. If that doesn't work, we need to find out how EOS utility performs the autofocus commands (that's what I did years ago on 550D iirc). Of course, assuming EOS utility can do remote focus on the EOS M (I do not have it installed).

ML/SCRIPTS/API_TEST.LUA:1094: assertion failed!

First assertion (line 1094) was probably picture not taken because camera couldn't autofocus. No big deal.

Note that there is an error towards the end of the log. Not sure what it means.

I've also got that last error a few times, in LiveView, on other models. It means ML tried to set some aperture, and Canon firmware picked something a bit too different from what ML asked. In this case, the difference was 0.26 EV, and ML expected a difference smaller than 0.1875 EV. Not sure why it happens, probably not a big deal either.

Don't have any EF-M lenses yet; the 22mm STM seems to be the only half-decent one (for what I'd use), but that's probably not the trickiest lens for ML.

An interesting lens is the EF-M 28mm f/3.5 Macro IS STM. It has a built in light and has IS so it shows the shutter-bug.

If you comment out the waiting functions from lens_focus(), it might work better. For example, for a quick test, one could use prop_request_change instead of prop_request_change_wait, comment out lens_focus_wait(), and set a larger delay in the focus settings menu. If that works, we need to find out how to tell when the AF motion was finished.

Tried this and it didn't work:

src/lens.c

Code Select Expand

                /* request and wait for confirmation */
                prop_request_change_wait(PROP_LV_LENS_DRIVE_REMOTE, &focus_cmd, 4, 100000);

                /* also wait for confirmation from PROP_LV_FOCUS_DONE */
                // lens_focus_wait();


I kept adding to the timeout value until I thought it was way too much but maybe I didn't go far enough?

If that doesn't work, we need to find out how EOS utility performs the autofocus commands (that's what I did years ago on 550D iirc). Of course, assuming EOS utility can do remote focus on the EOS M (I do not have it installed).

EOS Utility can do very little on the EOSM, certainly not tethered capture or anything like that.

Here is what EOS Utility looks like without a camera connected:



And this is what happens when the EOSM is connected:



Same thing with the EOSM2.

[a1ex]

                prop_request_change_wait(PROP_LV_LENS_DRIVE_REMOTE, &focus_cmd, 4, 100000);

Sorry, my English is broken. I wanted to say, don't use prop_request_change_wait, but replace it with prop_request_change (without wait). Then, from ML menu, you could configure a fixed delay, such as 50 ms or whatever. That one ends up as "extra_delay" in the source code.

If the lens moves after these changes, disabling our waiting for confirmation might do the trick (or, the diagnostic logs captured while attempting to focus could give further hints).

If the lens does not move at all... then all we can do is:
- capture debug logs during autofocus (need to find out who decides the direction and speed - the main CPU or the MPU?)
- disable focus functionality for EF-M lenses (easiest, but a bit messy)
- reverse engineer the MPU firmware (hard, time consuming, not a priority for me at the time of writing)

[dfort]

Your English is fine, my reading is broken.

Tried this:

src/lens.c

Code Select Expand

#else
                /* request and wait for confirmation */
                // prop_request_change_wait(PROP_LV_LENS_DRIVE_REMOTE, &focus_cmd, 4, 1000);
prop_request_change(PROP_LV_LENS_DRIVE_REMOTE, &focus_cmd, 4);

                /* also wait for confirmation from PROP_LV_FOCUS_DONE */
                // lens_focus_wait();
#endif




But still no focus movement. I take it that the message in the log is just from turning off the camera after letting it run several minutes.

The EF-M lenses haven't been able to pass the lua tests for as long as I can remember. Seems like everything else works but those lenses don't seem to move the same way EF/EF-S lenses move.

[a1ex]

If anyone has a (working) 50mm/1.8 II lens (not the newer STM), or any other lens that does not report focus distance, I'd like you to run the Lua API test with both unified (main) build, and with latest lua_fix experimental build. Camera model doesn't matter much.

Reason: I expect lens.focus to fail on these lenses, as discussed here, but the same function is likely to work fine in mainline.

[aprofiti]

I have problems running on 50D with a tamron 17-50mm wich doesn't report focus distance in focus tab.

Can't run because it lock the camera in both unified and lua_fix (tested unified feb 04-18 and appears to run up to AF test then camera powered down for uknow reasons).

This is what I got in the log of lua_fix:

Setting shutter to random values...


[a1ex]

To narrow down:
- comment out test_lens_focus (expecting the API tests to pass)
- run only the first half of test_lens_focus (before the calls to lens.focus)
- try a large delay in lens.focus (4th argument, which is optional); for example, 100 or 500 ms

BTW, is the 50D able to shut down cleanly with the latest lua_fix build? The 5D2 is not (it locks up with both LEDs turned on).

[aprofiti]

BTW, is the 50D able to shut down cleanly with the latest lua_fix build? The 5D2 is not (it locks up with both LEDs turned on).

What do you do exacly? If I use the build normally, it doesn't looks like it need a battery pull.
Camera freezes as described before if I run api_test.lua untouched and need to take battery out to power down camera.

Here are more detailed tests using lua_fix 20-03-19:

It freezes whenever I turn off the camera (no matter how - from power switch or from card/battery doors). Repeatable. Default settings, no modules loaded.

Script was running in an infinite loop and Lens AF was stuck trying go over infinity

Yes, this is what I was afraid it might happen, with the new heuristics.

This part of the test appeared to work, to some extent, in unified, so... it's a regression.

While it's stuck trying to focus over infinity, are there "Lens moving" messages on the console? These are not logged; they are just printed. If yes, can you show me a few values? (a screenshot would be fine)

No problems over here

Yes is a typo. Test runs fine if I change the string.

Don't understand why camera shutdown immediatly during the test.
This appen also with an older unified build (Feb04-18), I don't remember if this was an issue with older build than these ones

While it's stuck trying to focus over infinity, are there "Lens moving" messages on the console? These are not logged; they are just printed. If yes, can you show me a few values? (a screenshot would be fine)

Yes a lot of them... Even if I manually move the autofocus ring in the opposite direction, some hits and then agin stuck.
Give me a few minutes to take the sceenshoot

Old cameras will shutdown if the delay between focus commands is "too small" (Canon knows what exactly is "too small"). Your test log shows some successful focus commands, though.

If the limit detection (on Canon's side) is relying solely on motor current, lens.focus() will keep trying as long as the motor encoder (lens.focus_pos) shows some movement. If the motor "keeps trying", that might result in some movement (back and forth) at the focus limits (either macro or infinity), but lens.focus() will think the lens is still moving. That's the edge case I wanted to check, and I know for sure the 50mm/1.8 II has no limit switches; it only looks at the motor current. If user would stop the focus ring forcefully, ML would show the same error, i.e. "Focus: soft limit reached".

If the "Lens moving" messages are showing numbers with sign changing all the time (i.e. showing the encoder going back and forth), I should update the heuristic to interpret that sign change as "focus limit reached".

Autofocusing works in the tfirst stage (before pressing AF-ON) and then first second of the second stage, then reach infinity and get stuck

[a1ex]

That 1000 (a status bit) is what I interpret as "error". The odd part is - why does it always show movement in the same (positive) direction?!

If you enable Follow Focus (without loading the Lua module) and try to move the focus with the joystick, does that work? Similar messages on the console?

Yes similiar messages.



Positive values with left direction (infinity) and negative in the opposite (macro); also 1000 pop off immediatly when limit is reached, but stuck message after some tryes

[a1ex]

Interesting.

Is the motor still trying to move after reaching the limit? The first number (encoder delta) from the "Lens moving" message shows it might be. Or maybe the encoder value (as reported by this lens) is simply bogus?

[aprofiti]

It still try to move over the limits, but first it goes back a little bit and then change again in the selected direction...
Also the motor make a different noise than normal

[a1ex]

Understood. The lens firmware might be counting the encoder steps only when power is applied (i.e. when actively trying, not when it goes back after the motor stops).

BTW, this investigation was for solving this issue. The current heuristics from lua_fix appear to do the trick, at the expense of working only with "new" lenses (my only AF lens is 24mm/2.8 STM).

Is there a LiveView lua script to prevent the LiveView from timing out on 5d2? I am trying to use an external HDMI recording and the timeout after a minute is less than optimal. I tried a simple Lua script mentioned in the forum but that left the script running in an infinite loop overlaying on the screen making the video useless. Thoughts?

Possibly asked and explained before but I can´t find any info.
Question around reboot and boot function in ml. Can it be controlled in lua in such a way that we can delay a reboot process? Reason being it would save up on battery.
Been messing with this lately https://www.magiclantern.fm/forum/index.php?topic=9741.msg223238#msg223238 and battery drains of course and if I would like to for example do a two day timelapse I have to have camera turned on for the whole job but what if reboot process could be delayed early in boot process?
In lua_camera.c:

Code Select Expand

/***
Restart the camera.
@function reboot
*/
static int luaCB_camera_reboot(lua_State * L)
{
    int reboot = 0;
    prop_request_change(PROP_REBOOT, &reboot, 4);
    return 0;

    /* shutdown is probably done in a similar way, but I had no success with nearby properties */
}
Reboot is called with this in lua camera.reboot() if I´m correct.

So before I try something shitty and soft brick my eosm for the third time I would simply know if it´s something to even consider  . Hopefully @a1ex or ©dmilligan checks in here or anyone else with some knowledge around this.

Full shut down not possible yet if this is correct?

Not the answer you are looking for ...
- use an external power supply with sufficient capacity

I dream of making use of cam's internal watchdog timers ... but - as a1ex mentions frequently - we don't know that much about cam's DSP.

Not possible to program a timed reboot, to my knowledge. Assuming you are looking for something like the "deep sleep" mode in ESP8266.

The lowest-power mode, to my knowledge, is outside LiveView (e.g. in PLAY mode), with display turned off, and then: call("EnablePowerSave"). The last item, after you turn off the display, will probably cut the power draw in half, but not much more. With display on, it probably won't make much of a difference. Some numbers here (measurements done several years ago).

In that power saving state, msleep is not going to work any more (it will sleep indefinitely afaik, or until the CPU wakes up for some reason). You could probably hope for some interrupt to wake up DryOS every now and then, and that's when you might be able to check the real-time clock. I didn't explore it, as it interferes with the regular intervalometer and all other ML functions that use polling. And since it didn't seem to make much of a difference (IMO), it was much easier to just turn off this kind of powersaving globally.

This might be a good use case for reprogramming the MPU (hard, possibly risky), or for a hardware mod that would wake up the camera every now and then (such as, once every 10 minutes or whatever). The idea of having enough battery power for a 24-hour timelapse is quite tempting, but these options are not exactly straightforward.

Another "simple" optimization: since LiveView itself draws much more power, compared to e.g. PLAY mode, so it might be worth trying to record one frame as soon possible after entering LiveView (possibly before the screen even turns on), and to close LiveView right away, before the frame is saved to card.

You may consider the "classic" full-res silent picture + regular intervalometer; that one operates outside LiveView, with display turned off whenever possible, but without the CPU powersaving. That should give you a rough idea of what to expect, regarding battery life. On cameras with LP-E6 batteries, you even get a real-time battery estimation during the timelapse, on top of the image review (if you enable it in Canon menu). Even so, one battery is not going to last 24 hours, at least not on DIGIC 4/5 cameras.

See also this topic for an even longer answer.

[Danne]

So no "prolonged" reboot hack that I missed  .
Useful information and since I approached this from movie mode(mainly for convenience reasons) I could now benefit from working the full res silent picture  angle. Might have some tinkering time again over xmas.
Thanks for sharing links and info.

I installed the lua_fix branch because I'm trying to stream on OBS and wanted the 30 minute timer fix for LiveView.

However I can't seem to be able to change ISO and Shutterspeed using my camera buttons or the menu. On the menu it changes, but the hdmi output doesn't change. I set ISO to a number instead of of AUTO. Do I need to turn off auto exposure somewhere else? Are button defaults different on the lua_fix branch? Hmm actually whilst writing this, liveview turned off and I turned it back on, and it would let me do ISO with the button, but I can see ML smooth exposure.

[Walter Schulz]

You are off-topic. This is "Scripting Corner" related to Lua scripting language.

By default ML doesn't change button defaults other than trashcan.
If you haven't found out how to handle your issue you might want to do a follow-up. Please mention your camera type.

30-minute timer setting: Prefs tab/screen -> PowerSave in LiveView -> 30-minute timer Disabled
Expo settings: Expo tab/screen -> ExpSim OFF

Well... I can understand why he ended up here. Maybe you should update this link attached to Lua_fix builds in general or create a dedicated topic/space for Lua_fix builds discussion... 


Latest Lua updates + fixes (please review)
Latest Lua updates (details).
Includes many other backend changes, e.g. focus, menu, Q button handling, fonts etc.
Therefore, it's important to give it a good try on all functions, not just Lua, so we can include it in the nightly builds.
