dual_iso with 600D error: pgm width
« on: August 15, 2013, 10:03:58 PM »
I make a testshoot with dual_iso 100/1600. Using cr2hdr, a dng-file is not generated and I get this error:

Code: [Select]
Input file     : 1.CR2
Full size      : 0 x 0
Active area    : 0 x 0
Error: pgm width
I do not find this error string in cr2hdr.c. The tmp.txt looks like this

  no, opensuse 12.3

which programs? dcraw works and exiftool works too

latest dcraw?
  Latest from opensuse 12.3. But this dcraw-version is from last year. I updated to the recent dcraw, but no changes.

This error string
Code: [Select]
Error: pgm width where does this come from? As I said before, cr2hdr.c does not contain such a string. So I don´t know, where to search for the reason of this error.

Dual iso is only supported on 5d3 and 7d.
These are the only models that have two separately programmable ADCs

Compiling from actual MagicLantern source results in the same error (Kopfkratz)

I'm having similar issues with a dual iso test shot from my 700D:

Input file     : /tmp/IMG_5884.CR2
Full size      : 5280 x 3528
Active area    : 5208 x 3476
White level    : 13482
Black borders  : 72 left, 52 top
Black level    : 1982
ISO pattern    : BdBd RGGB
Interlacing method not supported
ISO blending didn't work


according to the source, BdBd means is_bright[0] && is_bright[2], so maybe the 700D uses another interleaving than other cameras?

cheers,

Check your ver of dcraw. I had no issue with 600D, 700D can't test.

latest 9.19 in Fedora 19. Also, the "BdBd - Interlacing method not supported" is from cr2hdr, not dcraw. I'll have to dive into cr2hdr.c as soon as I find the time.

the 700D definitely has another line interleaving scheme than the 5Dm3. cr2hdr reports "BddB RGGB" for the 5Dm3 and "BdBd RGGB" for the 700D. Page 5 of dual_iso.pdf talks about an interleaving pattern of l,l,H,H,l,l,H,H... for the 5Dm3, but I think the 700D uses something like l,l,l,l,H,H,H,H,l,l,l,l,H,H,H,H....
To illustrate, I cropped the first top left 32x32 pixel out of a 5Dm3 and 700D CR2, respectively:



Needless to say, current cr2hdr interpolation algorithms do not like this. I'll look into this some more, but maybe someone has some input already?

I found the error.

This happens, because my pc is set to my native lanuage (german).

As I can see in cr2hdr.c, you use dcraw to fill tmp.txt with important values and you read from tmp.txt to process the dual-iso-file. But you search for english expressions. Because of my system-settings, dcraw writes geman expressions to tmp.txt. So they never can be found and used for further processing.

If I change my system to english, decoding the dual-iso-file is running fine:

Code: [Select]
LANG=en LC_CTYPE=en LANGUAGE=en ~/cr2hdr 1.CR2
Maybe it would be a solution to hardcode the language to english for running cr2hdr?. No plan, how this can be done, because I cannot code in C, just read a little...

Does it work if you do the same trick in cr2hdr.c, for the dcraw command line?

Like this:

        snprintf(dcraw_cmd, sizeof(dcraw_cmd), "LANG=en LC_CTYPE=en LANGUAGE=en dcraw -v -i -t 0 \"%s\" > tmp.txt", filename);

@ alex

I read a bit about programming. Trying to learn it somehow ...

What do you think about this construct? This runs under OpenSuse. Windows and MAC I cannot test.

Code: [Select]
#if defined(__linux__)
/* Linux */
snprintf(dcraw_cmd, sizeof(dcraw_cmd), "LANG=en LC_CTYPE=en LANGUAGE=en dcraw -v -i -t 0 \"%s\" > tmp.txt", filename);
#else
/* all other OS */
snprintf(dcraw_cmd, sizeof(dcraw_cmd), "dcraw -v -i -t 0 \"%s\" > tmp.txt", filename);
#endif
