lv_set_raw / lv_select_raw
« on: December 11, 2016, 10:16:59 AM »
These are used for selecting the LiveView raw stream (aka "raw type", see PREFERRED_RAW_TYPE in raw.c).

There is a function that gives some more information about these modes: lv_select_raw in 70D, 80D, 750D/760D, 5D4 and 7D2. The debug strings also reference the PACK32 module (which is something that can write a raw image to memory), so probably this setting connects the input of PACK32 to various image processing modules from Canon's pipeline.

Some related pages: Register_Map, EekoAddRawPath, raw_twk, 12-bit raw video, mv1080 on EOSM...

The names appear to match between DIGIC 5 and 6 cameras, so here's a summary of the LV raw modes:

DIGIC 4 has a different mapping. 60D:
Code: [Select]
RSHD     => 0x0B
SHADE    => 0x01
HIVSHD   => 0x07
ORBIT    => 0x09
DEFCORRE => 0x04
CCD      => 0x05 (currently used)
DEFMARK  => 0x06

There are more valid raw types than the ones named in the above tables. For example, on 5D3 (trial and error):
Code: [Select]
0x00 => valid image stream in some unknown format
0x01 => bad
0x02 => scaled by digital ISO (DEFCORRE?)
0x03 => bad
0x04 => SHADE (bad pixels, scaled by digital ISO)
0x05 => bad
0x06 => bad
0x07 => DEFMARK (bad pixels)
0x08 => HIVSHD (bad pixels, appears to fix some vertical stripes)
0x09 => bad
0x0A => bad
0x0B => bad
0x0C => bad
0x0D => bad
0x0E => RSHD (bad pixels, scaled by digital ISO)
0x0F => bad

0x10 => CCD (clean image, some vertical stripes in certain cases)
0x11 => bad
0x12 => DEFCORRE (scaled by digital ISO)
0x13 => bad
0x14 => valid image stream in some unknown format (different from 0)
0x15 => bad
0x16 => bad
0x17 => bad pixels
0x18 => bad
0x19 => bad
0x1A => bad
0x1B => bad
0x1C => bad pixels
0x1D => bad
0x1E => bad pixels
0x1F => bad

0x20 => valid image stream in some compressed format?
0x21 => bad
0x22 => clean image
0x23 => bad
0x24 => bad
0x25 => bad
0x26 => bad
0x27 => bad pixels
0x28 => valid image stream in some compressed format?
0x29 => bad
0x2A => some strange column artifacts
0x2B => bad
0x2C => bad
0x2D => bad
0x2E => some strange posterization
0x2F => bad

0x30 => valid image stream in some compressed format?
0x31 => bad
0x32 => clean image
0x33 => bad
0x34 => valid image stream in some unknown format
0x35 => bad
0x36 => bad
0x37 => bad pixels
0x38 => valid image stream with some missing columns?!
0x39 => same
0x3A => clean image
0x3B => bad
0x3C => bad pixels, strange column artifacts (like 0x2A, but with bad pixels)
0x3D => bad
0x3E => posterization (same as 46)
0x3F => bad

0x40 - 0x7F => same as 0x00 - 0x3F (checked most good modes and some bad modes)

On 5D3 and 60D, the raw type "CCD" is the one we are using for raw video.

On EOS M, the only valid raw types appear to be 7, 11, 48, 50, 75, 80, 87 according to dfort.

Would be nice if somebody has the patience to try all the raw types on the 70D, as it's the only camera that runs ML now and has lv_select_raw.

I'm doing more extensive tests on the EOSM but to be clear these values are for rbrune's mv1080 experiments at commit 85b9246. On the development version that is on the main repository there are many more valid PREFERRED_RAW_TYPE addresses. a1ex suggested this change which opens up even more possibilities:

[EDIT] Just realized that this has already been merged into the raw_video_10bit_12bit branch so it is available now.

Code: [Select]
     {
         .name = "LV raw type",
         .priv = &lv_raw_type,
-        .max = 64,
+        .max  = 0xFFFF,
+        .unit = UNIT_HEX,
         .help = "Choose what type of raw stream we should use in LiveView.",
         .help2 = "See lv_af_raw, lv_rshd_raw, lv_set_raw, KindOfCraw...",
     },
