Thanks. The dump is called VRAM.BIN. Focus peaking build is the thread
with focus assist experiments.

of RAM, I'm afraid I can't allocate that much...
This means:
- only vector cropmarks can work here
- zebras and focus markers will overwrite Canon menus (and I can't fix that)
Can you post a screenshot of Magic Lantern screen on the external monitor?

camera on something, that's even better.
This time, the VRAM file will have around 4 MB.
Diff (what I've changed in the code since the last build):
- dump_seg(YUV422_IMAGE_BUFFER, 720*480*2, "B:/VRAM.BIN");
+ dump_seg(YUV422_IMAGE_BUFFER, 1920*1080*2, "B:/VRAM.BIN");

Alternatively, there are a number of different upload services you can
use for files that are larger than the average email host allows:

A buddy of mine uses StrongSpace, which has a nice simple interface:

* the LiveView VRAM (which is 720x480 without ext monitor) is 1920x1080.
Now, questions:
* Does the ML display center itself when you press Record? (with HDMI
monitor attached)
(from Cropmarks wiki page: "While recording it will switch back to 480p")
* Now I'm curious what happens with the other buffer, which we use for
silent pictures. Take a silent picture with the HDMI connected and
send it to me.
* The other unknown is how do we know when the monitor is connected.
To find this, you need to follow this procedure:
- I assume HDMI can be connected while the camera is on (there are
entries about this in hotplug_task)
- If anything goes wrong, take the battery out quickly
- Put a second camera to record the screen of your 550D (there will be
some very small text, so focus it well).
- Press Debug->Toggle draw_prop (you will see codes on the screen)
- Connect/disconnect HDMI display a few times
- After that, disable draw_prop and do a Debug -> dump dmlog
* If the camera display goes off when plugging the ext monitor, you
need to repeat the same thing by recording the HDMI display.
- Send me the movie(s) and the LOGxxx.LOG file(s) from your SD card.
See http://vimeo.com/groups/magiclantern/forumthread:236295 for an
example of how to do it (there's a link to a movie like the one you
should get)

¿is it the overlay segment? ¿from where dumps the bmp of display? if it is so we have a issue with HDMI output, not only we need scale all ML graphics (menues and so on) but also make aspect ratio corrections from 3:2 to 16:9.
Alex
Yes.
¿is it the overlay segment?
No. It's the segment from which are computed the zebra and histogram
=> can be downscaled.
The overlay becomes 960x540: http://magiclantern.wikia.com/wiki/Cropmarks
I believe the BMP gets cropped.
Cristian, can you take a pic of your HDMI screen outside LV mode? (in
M mode, for example).

If you can do another movie where I could read the fine print, that

whether the HDMI monitor is plugged in or not.

----------
When you look at the back of the camera there you see a detailed moving image stored in a video ram segement (vram). (I'll call this the ML vram .. as this is the one that Trammell used to calculate the Zebras)
When Canon help (or ML help) is displayed, it is stored in the overlay.
The is a nice mapping between the LCD screens 'overlay data' and the ML_Vram (1:1 pixel)
----------
Plug in an STD-def HDMI screen and you may everything goes a bit mad - but its actually ok.
What happens now is that the ML_VRram has empty black borders on the left and the right, and the image in the centre is squeezed in a bit. Its still the same resolution as the Overlay.
So ... if you do zebras .. there is still a 1:1 mapping. (720 horizontal resolution in both)
----------
Plug in an HD HDMI screen.
The ML_Vram now has a resolution of 1920 (I think) - including the bars on the side, and the Overlay resolution goes up form 720 -> 960 pixels.
Based on this ... I have wild guess that what you are seeing is the Zebras (or cropmarks) shifted to the right by ... (vram has twice as many pixels horizontally).
Based in my earlier guesswork (some may call theories), I guess all that is needed is for the Zebras or Cropmarks to now write their output to every other horizontal pixel (ie stretch by two).
Hope this helps! (Note: haven't got around to testing properly with a HD monitor yet .. )

Here is an extract from my vector cropmark code so that I can stretch/shrink my cropmarks.
It is not 100% perfect. Probably +- pixel in the Y axis, and +-2 pixels in the X axis.
I haven't learnt how to use DryOs properties yet ** , and so there is a bug in this code when using a HD_HDMI screen in Record mode ... which is that is doesn't register the fact that they screen resolution is zapped down to 480p (I'll sort this out later!).

Apologies for the 'jibberish' - what I was trying to write down was a possible software solution to the problem.

Looks like a HD HDMI monitor connected with ML in LiveView mode (1920 vram, 960 Overlay), then record is pressed (720 vram, 480 overlay). And you are experiencing the bug that I also have in my own code (in which I have not yet distinguished between the HD_HDMI monitor in 480 p mode, from the STD_HDMI monitor in 480p mode - the dryos has yet another 'squeeze' ratio).
This being the case - the Zebras should appear at a point 2 x the position of the item from the left of the screen (for the Live View mode = non-record mode)
And if that is the case - a new zebra plotting routine is required (in ML).
In my own code base - I've accepted this - and haven't written that piece of code yet.

What aspect ratio does the liliput monitor have? Does the image look
stretched on the monitor? (record a ball, for example).
Also try with an older ML (maybe the 0.2.0 release) which has
Debug->Draw palette. Take a picture of the ext monitor, with the
palette on the screen, when not recording, and another one when
recording. You may need to disable global draw so that the palete
remains on the screen.

The monitor is 16:9, but i can force 4:3 in the Menu.
All possible tests and writeups on resolutions, aspect ratios etc have
been done here:
http://videos.smallhd.com/the-truth-about-canon-dslr-output-signals/
The t2i seems to switch and squish the signal when recording - i can
confirm this.
Additionaly - I cant find a build with draw palette enabled :)

The standby mode is 1920x1080i @ 59.94FPS, the record mode is 720x486i @
59.94FPS. These modes are NOT affected by the PAL/NTSC setting of the
camera nor the recording format (480p/720p/1080p, 24,25,30,50,60FPS)!
As you can see the ML-Zebra/Focus-OSD is shifted some pixels to the
right and down. In standby pressing the DISP button changes the live
view area which messes up all the ML-OSD.
Deti
Alex
I've found some other buffer sizes: http://magiclantern.wikia.com/wiki/VRAM/550D
What I'm missing is the size of 0x44000080 in standby mode with HDMI
connected. Cristian's 422 silent shot is 1056x704. When a SD monitor
is connected, silent shots are 1024x680. I believe it should be higher
with HDMI monitor.
Sawo said zebra works OK when recording with HDMI connected. How about
focus peaking?
Alex
(zebra uses 0x40D07800, focus uses 0x44000080 because it has higher
resolution... at least when ext monitor is not connected)

I have been doing quite a bit of reading into the lilliput monitors (I don't own one, was trying to figure out if it is a good idea or not).
The whole resolution/aspect thing looks pretty subtle and complicated.
That link that sawomedia posted earlier does explain it really well
http://videos.smallhd.com/the-truth-about-canon-dslr-output-signals/
This is what I believe is happening... any or all of this information may be incorrect. ;-)
The lilliput monitor has a resolution of 800x480, aspect ratio of 15:9.
While recording the 550D sends a 675x450 image centred on a 720x480 (486?) signal.
This results in black bars at the side and top.
Unfortunately the monitor doesn't seem to make very good use of this signal, the best results seem to be gained when having it set to DVI mode and 4/3 aspect.
Hope some of this info is useful, here are some images to help illustrate the results.
The first is from the smallhd page linked above.
and from a forum post showing the different display options.
http://www.dvinfo.net/forum/view-video-display-hardware-software/484963-550d-t2i-lilliput-8-869gl-problem.html

The resolution is horrible, but it would work with focus peaking.
Focus Peaking points are bit shifted to the right, zebras dont work at
all.
I can provide a screenshot if necessary.
I (naively) that RCA would work without a hassle, as the image is just
pushed to the external monitor.

Or take pictures.

external monitor.
I suggest to try these steps:
* With HDMI in standby (not recording), LV should be 1920x1080.
* Dump the RAM (last item in Video menu) => you'll get a 256MB file named 0.BIN
* Run hunt.py to find those numbers. To do this, change those 2 lines:
A = findaddrs(1056) --- replace with 1920 or 3840
B = findaddrs(704) --- replace with 1080
Post the output here (it will find pairs of addresses which may
contain VRAM resolution).

So, to summarize:
* I know how to detect if a monitor (HDMI or SD) is plugged in:
PROP_INT(PROP_USBRCA_MONITOR, ext_monitor_rca);
PROP_INT(PROP_HDMI_CHANGE, ext_monitor_hdmi);
* BMP VRAM sizes are known (found by Trammell). 720x480 or 960x540.
* There are LOTS of resolution combinations of the image VRAM buffers:
http://magiclantern.wikia.com/wiki/VRAM/550D
* I've found a method to get the buffer size when external monitor is
NOT plugged in and camera is NOT recording
(this means zoom 1x 5x 10x, photo liveview, video liveview in all 4
movie resolution presets). Seems reliable in my tests.
* TODO:
- how to get buffer sizes when external monitor is NOT plugged and
camera is RECORDING (I'll try this tonight)
- how to get buffer sizes when external monitor is plugged? (both
recording and not recording)
(not yet solved, but we have some guesses)
Other stuff to be solved:
* Coord transformation between LV and BMP (was not needed until now,
because they are usually the same size). Should be very fast. I think
it's only a downsampling by 2.
* Coord transformation between HD and BMP (I'm using this in focus
assist code). It seems to be more than a simple scaling. Not
time-critical.
* Cropmark transformation (was not needed). Trammell proposed separate
bitmaps (best quality, but inconvenient). I think scaling will get a
usable result. Also, not (too) time-critical.

simply have to calculate the whole vertical resolution for Disp x1/x2
with this aspect ratio to the the horizontal number of pixels:
1080*3/2=1620. So you will have to look for 1620x1080 in the RAM -
that's all.

Other question: when recording with HDMI plugged, zebras are already
in sync, which means the pitch of the LV buffer (0x40D07800) is 720*2
(i.e. horizontal resolution is 720px). This is also confirmed by your
test (Untitled 1_3).

Yes the zebras are in sync, the focus peaking not.

Well the 640 is the width of the live view area which also can be 1320
or 1620. According to this knowledge we can determine the where to draw
the OSD:
- in the 640 mode the LV area is already centered with no borders
- in the 1320 mode the LV area starts at offset 300
- in the 1620 mode the LV area starts at offset 150

- Zebra uses the LV buffer: 0x40D07800
- Focus peaking uses the HD buffer (due to higher resolution): 0x44000080
- We are drawing on the BMP buffer
With builtin display, LV and BMP happen to have the same resolution.

should use this buffer for all those image related operations. The
positioning of the overlayed BMP content has to be adapted dynamically
to the found LV areas. Is the BMP buffer resolution always 720x480?
When we take the HD buffer only, we can do zebra and focus peaking in
one for loop to avoid reading several times the same buffer.

The HD buffer depends on:
- Video resolution (even when not recording!)
- zoom 1x 5x 10x (we may ignore that and disable zebras/focus in zoom mode)
- recording / non recording state
And it seems it does not change when we plug the HDMI buffer. This can
be confirmed/infirmed with silent pics (but not in current builds).
Here are my latest hypotheses about this buffer (not yet 100% confirmed):
http://magiclantern.wikia.com/wiki/VRAM/550D#0x44000080
Morgan Look
> And the output resolution changes due to this?! Pretty strange...
This post shows how (on the 5D), some of the LV info stuff is presented
outside the active video area (into the black bar area). So this buffer
resolution changes is making room for these I guess.
This implies you may be able to put additional information into the
black borders around the video in various modes.
Morgan.
Alex
size: http://magiclantern.wikia.com/wiki/VRAM/550D#0x44000080
The main guess is that this buffer does not change its size when
plugging an external monitor. To validate this, silent pics taken in
all modes should be decoded correctly by 422-jpg.py from this zip.
Without monitor connected, the test worked for me in the following modes:
- Photo: zoom x1, x3, x5
- Video: full HD, 720p, 640crop (both recording and not recording)
- 640 non-crop, when recording only
It dit not work in 640 non-crop when not recording (I've got only
horizontal bands).
Can you do the silent picture tests with external monitor (HD or SD) plugged in?
Deti
> Can you do the silent picture tests with external monitor (HD or SD) plugged in?
Deti
Alex
Can you test also in 720p and maybe 640 modes?
Another bug: in 720, while not recording, sometimes works and
sometimes not. Probably the buffer is dynamically allocated from a
list of preset addresses?
