General Chat / HDR / SDR / DOLBY / nits and bits ...

« on: February 16, 2017, 10:40:26 AM »

All new TVs are actually "marketed" with the HDR term. No clue really what he's writing about (Rec.2020, ST.2084, highlights...) and I don't think that the user base is already grading "HDR" at the time of writing this. Still found this interesting to share:

General Chat / Research exemption for consumer devices (DMCA)

« on: November 04, 2016, 11:43:15 AM »

I am not a lawyer but stumbled upon a positive (in terms of my view) article / news:

https://www.ftc.gov/news-events/blogs/techftc/2016/10/dmca-security-research-exemption-consumer-devices

Some of us are located in Europe but as far as I understand, it sounds (again I am no lawyer) like devs located in U.S. could try ML on a 1D blabla now. Don't blame me for the news please.

General Chat / Canon W-E1 WiFi adapter

« on: August 08, 2016, 01:34:33 PM »

Normally I don't tend to take rumors seriously but this one caught my eyes for the last days as a "WiFi adapter" is rumored to be announced in a few weeks:

• WiFi adapter in EyeFi (size of an sdcard) form factor (maybe allowing for use of microsd??)
• EOS Utility compatible (remote controlling etc....)
• ...and therefore some type of PTP/IP through DMA controller which again would open new ways for hacking and tweaking our cameras.
• At least said to be compatible with the 7D Mk2 but I hope rumors become true and lots of cameras are going to get a fw update (crosiing fingers for getting rid off revision handling for SL1 / 70D)

http://www.canonwatch.com/canon-w-e1-wifi-adapter-sell-less-40-cw3/

Btw: a1ex was experimenting with FlashAir cards from Toshiba a while ago so if the rumors become true you are going to start from scratch

Reverse Engineering / JTAG / UART & more

« on: March 09, 2016, 08:02:54 PM »

Hi everybody,

I've been playing around with Espressif's ESP-modules lately for some private projects.

OT-OT:
i can recommend NodeMCU (http://en.wikipedia.org/wiki/NodeMCU)
...

Guess, who's playing actually with it 

Anyways I just ordered a Bus Pirate V3.6.
My goal is to JTAG our EOS cams. A big package of older cams, mainly EOS 10D, 20D, 30D, 40D, 50D,1000D and 650D should arrive in the next weeks at my door (thanks @Dayton) and I am going to start to get familar dismantling them. Main focus will be JTAG for 50D and 650D and I hope to get access to the bootloader / kernel in some way to get more insights of the cams. There's UART, so there must be a bootloader, too. This may become useful for linux development in some way. Maybe we can get U-BOOT ported to our cams or I am going to fail right at the beginning, who knows? Will keep this post updated from time to time but don't expect miracles anytime soon, I am just going to replicate this tutorial to EOS dslrs and with some luck and hope there will be results to report and try on Digic6 cameras   .

Magic Lantern Forum and Site Discussion / Forum upgrade

« on: March 02, 2016, 10:13:39 PM »

Guess the responsible ML webmaster has already noticed but the chdk project has upgraded it's SMF forum. So if time or help is needed to achieve the same goal as chdk i will be here to help wherever I can. Got myself a phpbb forum years ago before I closed it and am familar with Joomla and such....

Noticed several times spam posts coming through. maybe that could be a motivation to upgrade the site for you? Otherwise a new look & feel combined with a better inbuilt search engine for the community should at least help mods like Walter to focus on "real" problems instead of repeating themselves dozens of times.

General Chat / Black Friday Deals: Chit Chat

« on: November 23, 2015, 08:34:54 PM »

Was looking into the 55-250 IS STM as I read everwhere it does a great job. What's wrong with this deal (109.99$ at time of writing):

http://shop.usa.canon.com/shop/en/catalog/ef-s-55-250mm-f4-5-6-is-stm-telephoto-zoom-lens-refurbished

Cannot seem to find any price even close to that in Europe. Wish canon had a refurbished shop in Europe but seems there are only ebay listings available rather than a shop.

Reverse Engineering / lv_unpack_raw?? Any idea what that does?

« on: May 31, 2015, 11:09:29 AM »

See attached picture (click to resize). Ever seen this on any other rom / camera? Tried to call it like lv_save_raw but maybe I was incapable of understanding how and what to do with lv_unpack_raw. There's also this DAF (0x7ADC8). It is seems to be a state object (there's string DafState.c in ROM or it might be a property) related to EVF and get's logged in dm.log's but I can't seem to find it in a1ex's bitbucket state object diagram pages for 70D. I think DAF could be related to 70D's DualAutofocus but it's just a guess. Anyways I tried to search for lv_unpack_raw but couldn't find any infos on that. Searching for it in another ROM didn't yield to a result...

Code: [Select]

DAF:ff0d8648:be:03: [DAF] dafProperty break 5
DAF:ff68aefc:be:03: GetDafKParam 0112
DAF:ff0d7f64:be:03: [BP] lens BP

General Development Discussion / EDMAC Screenshots

« on: May 24, 2015, 10:56:19 AM »

Could need some help please. Can you post screenshots from "Show EDMAC" in debug menu while in Liveview mode with global draw on? The first overview page would suffice my needs. We can use this thread for collecting actual screenshots for all models. There are some old screenshots available here and there but not really much of 'em after merging-in FRSP branch. I would be interested in 5D3 (113 / 123) screenshots but any other DIGIC5 cam should do the trick for me, too.

Note: Some cameras have EDMAC_RAW_SLURP" enabled and the screenshots of those may vary...

70D.111A looked like this before implementing some changes. Note: added comments to the picture in yellow color (click to resize):


70D.111A looks like this after using edmac raw_slurp to channel1:

http://i59.tinypic.com/2s5zgi9.png
To be updated later by me for all 3 cases listed below.

Please add yours with model and FW version for the following cases like instructed (no more, no less):

• Case1: Turn on camera. Switch to LiveView. Take the screenshot from EDMAC's 1st overview page.
• Case2: Turn on camera. Switch to LiveView. Take a picture and afterwards take the screenshot from EDMAC's 1st overview page (no other actions in between).
• Case3: Turn on camera. Switch to MovieMode. Take a H264 video and while taking the video make a screenshot from EDMAC's 1st overview page.
• Case4: Turn on camera. Switch to MovieMode. Take a MLV video and while taking the video make a screenshot from EDMAC's 1st overview page.

"HighJello-FastTv" should be able to set whichever desired fps from 0.X to 25fps. All others like "exact fps, low light" won't go below 16.666. In rare cases it might happen that you need to disable and re-enable fps-override to get it working. You may also encounter that you might need to switch from MV / LV to photo mode and back to get it working...

Reverse Engineering / [Q] How can I find DEFAULT_RAW_BUFFER ???

« on: August 31, 2014, 02:29:58 PM »

Hi,

I wanted to define CONFIG_EDMAC_RAW_SLURP in internals.h but looks like I need to find DEFAULT_RAW_BUFFER for my 6D. In raw.c there's some hints how to find it and there's also

Code: [Select]

#else

/* with Canon lv_save_raw, just read it from EDMAC */
#define DEFAULT_RAW_BUFFER shamem_read(RAW_LV_EDMAC)

#endif
Shouldn't above code define it automatically or is it obsolete?

General Development Discussion / [Q] Diet libc ???

« on: July 26, 2014, 10:19:11 PM »

Hi,

just wanted to ask why ML switched to diet libc in early 2013? Was it to be able to shrink file sizes as much as possible and being able to use TCC, too??
Another question: Last weeks I have heard lots about  "musl libc" as it seems to become more and more used in community / opensource projects (e.g. openWRT). Please have a look at the following comparison http://www.etalabs.net/compare_libcs.html

Could this or parts of it (cherry picking code) be useful for us? What do you think?

Feature Requests / [INVALID] Dual iso to improve low light shutter speed

« on: July 01, 2014, 07:19:44 PM »

Yes, I tried to search to find dupicates.
No, I couldn't try myself as I have still no cam so scratch that if it's not possible or already done.

Could dual iso be of any use to improve low light shutter speed and get a correct exposed picture after postprocessing? As I know dual iso improves DR. You have to post process the outcome to get a nice looking improved picture.

Now take this. let's assume I have no image stabilization in my lens. I have no flash or can't use it. I would have to expose let's say a picture at iso 3200 and 1/5th of a second with an attached lens. Could dual iso be of any use here? Let's say I set "low light dual iso" in camera and now I could take the shot with iso 800/3200 (or whatever) and 1/40th of a second. thi would avoid blurry image by hand shake and the outcome would be dark. But after post processing I get the same look (not HDR alike) like shot without dualiso and normal iso 3200 and 1/5th.

So using it for overriding camera values when operating in "aperture priority mode" in low light to get faster shutter speeds and postprocessing afterwards on pc. Hope you got what i am thinking of. Some might ask why not simply set iso to 6400 or anything like that. It's just an idea of myself if dual iso can be of any use in such situation.
