File format change
« on: March 03, 2019, 10:45:41 AM »
Hello. Help please. How to implement silent picture mode with the ability to save dng as cr2? In this case, let only the extension and not the file format change. This is necessary in order to pick up files by usb cable.

if you are able to compile ML you could edit/expand FEATURE_EYEFI_TRICKS that is doing same thing for CR2 (renaming the extension to AVI so eye-fi card will transfer them and then rename back AVI file to CR2 on the pc).

EDIT: after taking a look at it i've ported the feat to a module and added the option to rename .DNG to .CR2

Code: [Select]
/*
 * EyeFi Tricks (EyeFi confirmed working only on 600D-60D)
 */

#include <module.h>
#include <dryos.h>
#include <bmp.h>

int check_eyefi();
void EyeFi_RenameCR2toAVI(char* dir);
void EyeFi_RenameAVItoCR2(char* dir);

void EyeFi_Rename422toMP4(char* dir);
void EyeFi_RenameMP4to422(char* dir);

void EyeFi_RenameDNGtoCR2(char* dir);
void EyeFi_RenameCR2toDNG(char* dir);

/* since now it's a module is up to the user install on eye-fi card or not
int check_eyefi()
{
    FILE * f = FIO_OpenFile("EYEFI/REQC", 0);
    if (f)
    {
        FIO_CloseFile(f);
        return 1;
    }
    return 0;
}*/

        return;

    do {
        if (file.mode & 0x10) continue; // is a directory

now is up to you to compile it with your preferred branch and test, I've did not tested it just verified if compiles...

Haven't tested it:
silent.c, line 170
Code: [Select]
        extension = "DNG";change to
Code: [Select]
        extension = "CR2";

The difficulty is that this is not a programmer.  :-[  I turned to programmers familiar but they could not compile the module. how to compile them?

Try https://www.magiclantern.fm/forum/index.php?board=25.0 sticky topics
"Compiling Magic Lantern on a Macintosh"
or
"Compiling Magic Lantern on Windows 10 (using its Linux subsystem)" for starters. I'm not a programmer either and have no clue how to build a development environment on my own. Following dforts instructions worked pretty well.
I have to assume the programmers you contacted are not familiar with Bitbucket/Mercurial and GCC. You can do it with and without them, believe me.

As Walter says following the guides is easy to install a toolchain and compile ML without development experiences but some command line expp. is better.
If you manage to have the toolchain and compile ML you will then find out that it's not hard do make small changes to the code for personal needs.

Try this module, you have to use one of the last experimental versions but I'm not sure it will work. If camera freeze pull battery and disable the module.

If it loads you will have the new option eyefi tricks in Shoot

Report back how it works, or not. thanks

@a1ex: Some hint about the EyeFi section in Shoot menu, please.
I inserted my Eye-Fi card into 650D with latest nightly, enabled EyeFi support in Canon menu. There should be a entry called "EyeFi Trick" in Shoot menu. According to feature matrix 650D is supported (Prefs -> EYEFI_TRICKS).
Nothing there. Failure to detect my EyeFI? Does it have to be connected?

In order to display that menu, ML checks for a file named EYEFI/REQC. If that file is not there, ML assumes there's no EyeFi card installed.

However, this feature could be useful for other purposes, not just EyeFi. I'd rather be tempted to rewrite it as a Lua script, so users can customize the file renaming tricks as needed.

For existing code, I believe the EyeFi support can be diagnosed in QEMU. You will need to run it as root, as it needs raw access to the SD card. No idea if or how it works under Windows.

Or, to test that code, just comment out the check.

Thanks, will remove the check! Looks like check is not working for my cam at all.

@scrax: Tried your module with 650D, latest lua_fix build. Works!
With nightly build module won't load with "OldAPI" message which seems a bit odd.

I have version 7 (7D) when I loaded the module, I saw the inscription version 6 is expected. nothing appeared in the shoot menu

Scrax's module works perfectly fine on 7D with experimental lua_fix build. Top of page -> Downloads -> Downloads (drop down menu) -> Experiments

I checked with lua_fix build and yes it works for me too but after I restart or open and close the cover for the memory card. Another minus is the long renaming. Let's say if I have 30 frames then it will take time, but it's better than nothing. :) Thank you so much!

I think becaue I build t from a bleading edge branch i suppose the lua_fix branch added one more version number probably the error don'r make difference from "too old or too new api"

btw, I removed the card check in the module because I think that you can install/enable it if you have the card (or whatever reason) that way

EDIT: Here there is a PR to include the module without the eyefi check in the nightly: If the module works on your camera please report back camera model

I've compiled the module with unified build and now it should works on those builds, instead of the bleeding edge

Code: [Select]
[ HGDIFF   ]   hgdiff.tmp
[ MODULE   ]   eyefitrk.mo
[ STRIP    ]   eyefitrk.mo
[ OBJCOPY  ]   eyefitrk.mo
[ RM       ]   hgdiff.tmp
[ EXPORTS  ]   eyefitrk.sym
0000002c change_extension
00000134 EyeFi_RenameCR2toAVI
00000168 EyeFi_RenameAVItoCR2
0000019c EyeFi_RenameDNGtoCR2
000001d0 EyeFi_RenameCR2toDNG
[ DEPENDS  ]   eyefitrk.dep
Will load on:
    1100D, 500D, 50D, 550D, 5D2, 5D3.113, 5D3.123, 600D, 60D, 650D, 6D, 700D, 7D, EOSM

Atached here the compiled module, as usual please take time to report back if worked or not.
