Canon 7D Mark I

[arrinkiiii]

Where some stuff from ML that don't exist or not working correct,

-Zoom 10x  stay hang, pressing play button it get out of that freeze state.
-No MLV
-No Audio


I have made some tests with raw_mo but i don't know if it's worth to write here or to do more tests... Wait for the MLV?  Other stuff looks to work good. I need more modules for try out, this build/version  just have this modules.

raw_mo
dual_iso.mo
ettr_mo
autoexpo.mo
file_man.mo
pic_view.mo

[1%]

Easiest on the list
*Audio
*Display filters (just like 5DII/50D)

Harder:

Headphone from slave --- it has to be toggled on, there is no way to detect connection
FPS override for H264 -- It can be done from slave, needs help with unexpected video stops

If I use EOSCard from Pelican to make new bootable card for 7D, it already includes an MLV.mo, I still updated the install from jenkins Jan 21 build which does not have an mlv.mo.

Is this MLV mo from eoscard considered from ML or TL? so I'd know if I should test it and report.

This build Lacks:

Audio:
-The option to choose channels
-Headphone monitoring
-External mic controls
-Gain controls
-MLV Sound

Movie:
-FPS Override
_don't know yet if MLV from eoscard is TL or ML so holding report on this.

[arrinkiiii]

I think is just the modules that are in the folder. From EOScard is from TL... but for sure that someone will tell better then me.

[1%]

I thought EOScard went ML->TL->ML... really I don't think it should be downloading any builds, just making the card bootable/etc. Maybe verify file/folder placement instead.

So for this, just make another repo from the current tree and add the audio/display filter? Then I guess we can see how to port the other things which are left... also the dual ISO preview never made it into main + what is the word on named bracketing like B01, etc... it was much more reliable than dual ISO custom prefix.

After 2.03 is brought up to par... I guess can move to porting 7D. 205

Yes 

[1%]

I'm not that excited with 205... I don't think they modernized any parts of the FW. Im predicting it will just be like 6D112 -> 6D113, a bunch of changed addresses and thats it.

5DIII going to 123 has completely changed stuff.

[arrinkiiii]

I think that your talking about ML stable version and not canon fw. The fw 2.05 i think just have one update, having to do with  FTP with a USB cable and WFT-E5 transmitter.

[1%]

Both... 2.03 needs all features in main and then 2.05 update needs to be ported over in both.

[arrinkiiii]

Where can we find the new builds for the updates in ML Nightly 7D (with MLV_MO) ? It was removed from here http://builds.magiclantern.fm/#/ 

[1%]

You'd have to compile. 7D was never that far behind, could have had a nightly for people to chose, stable, experimental. The first pull request is up with 90% of audio. Just needs headphone ported and the wav is disabled because it can't use the memory backend or the memory leak gets out of control.

[arrinkiiii]

Ok, thanks 1%  Sometimes i think i understand and then... nikles.  I think that wend dev's start to porting stuff from TL 2 ML it show up here http://builds.magiclantern.fm/#/   


Anything that i can help for putting the 7D ML on the branch/nights/main/maintenance  just let me know.

give it a go when someone compiles it.

[7Dphotos]

Which version is suggested for bracketed HDR work?

[1%]

Besides the naming of bracketed shots to B01 they should be identical for this feature.

[7Dphotos]

Sorry for the totally NOOB question but where do we dl most recent version of ML for the 7D?

[arrinkiiii]

You need to compile... or wait that someone compile it.

[7Dphotos]

What is the latest compiled version and where to find it?

[Stedda]

You need to compile it yourself or wait for someone to share their build but someone already to you this....

the wav is disabled because it can't use the memory backend or the memory leak gets out of control.

Nope, the memory backend catches the bug, and by disabling the memory backend you are simply ignoring the error message (and the bug is still there).

Moreover, this bug causes the wav recorder to write on unallocated memory => undefined behavior.

Then why no crashes and missing memory? With the back-end on I get an error 70 from canon after the memory counts down. Without it, looks like all or most memory is released and no ERR70. Wavs record for a long time. I know the leak is still there for like a few kb but its not the monster that happens otherwise. Either way it will need a fix as the cameras make a really nice sound recorder. Esp. if you have more than one and no digital recorder.

The effects of undefined behavior range from nothing noticeable to anything you can imagine.

Hope there is a way to solve this properly.

edmac memcpy will cause issues while writing H264 since the channels will probably be in use.
