Hello everyone,
I'm thinking on a virtual/augmented reality project in which you wear a wielders mask (like this) and an android smartphone attached to its vizor. Because the phones screen is going to be so close to the eyes I need to know if it's possible to change the user interface to side by side parallel format stereoscopic view. That way it will be possible for the eyes to focus to the image onscreen with the aid of convex lenses. It doesn't have to be 3D, i just need a technique to turn what's shown on the screen to side by side parallel format.
Please reply, thanks...

I should wait for a couple of months if I were you. Check this out: Oculus Rift search for it on YouTube, this thing is awesome and I think is totally what you're looking for, only better!

I have been converting some 3D movies to watch on the Evo 3D. 16:9 movies display perfectly. However, if a movie has an aspect ratio wider than 16:9, the Evo 3D always plays it stretched. The Evo does not allow you to change the playback mode between "best fit" and "full screen" while in 3D mode. That being said, if you choose "full screen" while in 2D mode and switch to 3D, the result is as expected: no black bars, but video stretched. If you choose "best fit" while in 2D mode and switch to 3D, black bars appear (as you would expect), BUT the video remains stretched, and the black bars actually trim the image.
So, other than editing the video and adding black bars, it looks like we're stuck with stretched faces. =(
Has anyone else noticed this? Any other solutions?
Thanks!

EDIT: Forgot to mention, 1st picture is 3D full screen, 2nd picture is 3D best fit, 3rd picture is 2D full screen, and 4th picture is 2D best fit.
It was right in front of my stoopid face!
Change Handbrake's cropping to custom, at least for videos whose source is 16:9 anamorphic.
Continuing the monologue...
I came across a 1920x800 file, and Handbrake doesn't seem to have the ability to add black bars, so I ended up cropping Left/Right to fill screen while maintaining the correct aspect ratio. This is good in a way because you maximize the use of the Evo 3D screen, but I may not want to do that to every wider 3D movie I come across.
Does anyone know of a quick and easy way to add black bars to an mp4?
Thanks.
M
EDIT: Yeah... don't do what I did (crop left/right). Pretty dumb move.
Yes, the cropping thing is a bad idea because it will crop the right side of the right image and the left side of the left image, leaving you with a completely misaligned 3d image.
I am at the same point as you are (or were). Cropping is not the way to go, but i will try to add black letterboxing bars. This seems to be not possible in Handbrake, but there must me some video encoding software that will let me do this. I will post if i have a solution.
As i do not like letterboxing, it would be ideal to have a solution here it would be possible to crop from the middle of the video, where the left border of the right and the right border of the left image are, if you know any video software that can do this, please post it!
I crop them, because if I don't I have black bars and I wanna use the whole screen when watching 3D.
How do you crop a SBS 3D video? All video encoder programs i know let you cut away the right and left border, but if you have a SBS 3D video, you would need to cut away the middle of the video too, where the other borders of the two images meet.
If you have a method to do that, please share it, as i too would like to use the whole screen.

Okay, i have had success in adding letterbox bars. I have converted a 1280x538 video to a 960x540 and added letterbox bars, so it is displayed without distortion now. I don't like the black bars though, so i hope DexterMorganNL will elaborate on his method to crop the sides of 3D SBS video.
P.S. I used Sothink video converter, in the "advanced" tab on the right side of the window just select 960x540 as "Dimension" and click on convert.
I crop the Top and Bottom below away when converting with handbrake. It works good, I already watched 3D movies that I needed to crop.
It looks like we misunderstood each other then. It seems you were talking about movies with a lower aspect ratio than the phone's screen, for instance 4:3 (=1.33:1). If you add black bars to the sides of a video, it is actually called pillarboxing, by the way.
However i was talking about movies that had a higher aspect ratio and are therefore wider than the phone screen. For instance the video i converted to test the letterboxing had a resolution of 1280x528 which roughly equals 2.39:1, a common aspect ratio in cinemas.
For those videos, i currently have no alternative to letterboxing, as you cannot crop the sides because of the reason already described.
OK, i have sucessfully cropped the left/right borders by creating an avisynth script that first crops away everything but the center part of the left image that i want to keep, then does the same to the right image and finally combines the two center portions of the two images side by side. This is the script:
Code:
Sourcevideo = FFVideoSource("C:\Example\Example.mkv") # <= Loads the 3D-SBS source video
Lefteye = Sourcevideo.Crop(80,0,-720,-0) # <= Cuts away 80 pixels from the left side and 720 pixels from the right = the center portion of the left image is kept
Righteye = Sourcevideo.Crop(720,0,-80,-0) # <= Cuts away 720 pixels from the left side and 80 pixels from the right = the center portion of the right image is kept
Combinedvideo = StackHorizontal(Lefteye, Righteye) # <= puts togeter the two center portions side by side
Return Combinedvideo # <= Outputs the two portions as SPS 3D video.
This script was made for the 1280x528 mkv video i mentioned earlier. Obviously you have to change the amount of pixels to be cropped if you want to crop video of a different resolution. For a 1920x800 video, it would be 1084 and 124 pixels, for instance.
I used MediaCoder to load the avisynth script and encode the new cropped video. As the audio does not need to be changed, i extracted it from the original .mkv file with MKVextractGUI2 and loaded it with Mediacoder, enabling the "External File" checkbox (and also the "Copy Audio" one, as the audio should not be reencoded).
Of course you need Avisynth installed in order to do this, plus the FFmpegSource2 plugin.
So, i'm pretty happy and i think this answers the original question of the OP.

No problem, it would have been a waste spending time and effort to find a way to do this and then not share it.
If you have any question, let me know.
Oh, and btw, additionally to avisynth you need to have the FFmpegSource2 plugin installed, at least for .mkv files. It is possible you'll need other plugins for different input files, i am no expert on this stuff.
Heho
isn't there a community for software development for the evo 3d?
I`ve downloaded the SDK and got the 3DS Examples running well
using eclipse and my shooteru. I would like to programm a small
opengl 3d menu using min3d Framework. (see attachment)
Now i would like to use the code of the s3d demos to display this
menu in 3d, but i wasnt able to use the code for min3d renderer.
So i hoped there is a community for development for the evo 3d
but don't seem to be.
I made some changes to the min3D code to display stereoscopic 3D. It works on most samples, except 'Panorama', '3D in layout' and 'transparent layout'
The 3D can be enabled/disabled from the menu.
hey sound nice .. can you tell me how or send me some code snippets or something inspireing?
Both you guys might want to shoot toast a PM I know he was trying to get the 3d feature working on CM7. There might be lots of fun stuff there for you guys!
I had a look cm7's web and found that it only works on cdma evo. I unfortunately have a gsm phone. But thanks =)
Here is a link to the app:
http://www.fileserve.com/file/NwNcW2X/min3dSampleProject1.apk
You cannot tune the stereo convergence or separation. It 's fixed.
Enjoy
Thanx,
Nice,but apperently the speed of the Demo apps are noticeable slower.
Hmm now i see that its working but am not a bit smarter
Got some Tips how you did it? Also i have a question about the Panaorama Example.
I´m still new @ all the GL programming. I also created a skybox with nice skybox
textures from humus.name but i always see the borders of the box..
The textures are clamped to the edges of the box but if i rotate my Skybox
i see the edges.
thanks
Thomas
TommyX235 :
I also tried to make a skybox to display panorama, and I also got visible edges. I tried to displace cube's face, and/or displace textures with no result. I tried small box sizes 0.1 and large 10000 with same bad results.
The panorama sample is written by me and is not part of the min3D sample. It's a textured sphere.
Does anyone know if there already is a camera app out there which basically allows you to select an image from the gallery, set the transparency and it acts like an "onion skin" (transparent layer, like when you do animations)? Example: http://img-ipad.lisisoft.com/img/1/9/1907-2-overlay-camera-lite.jpg
The purpose for this will be for example copying a face expression and angle as precisely as possible, for later replacing in animated gifs (face swaps basically). It's really hard to look at an image on the computer and trying to take a selfie that's exactly the same expression and angle without a camera function like this.
If there isn't such a camera out there, anyone willing to make such an app? I'm sure it will be appreciated by the masses for a wide range of uses (like regular stop motion animation and such)
Greetings everyone!
I'm trying to make an app as part of a project of mine where I need to illuminate the object I'm taking a picture of (front camera) with different colours, provided by the screen itself. I'm new to android programming and so far have only been able to access the camera (the one in the back, since from my research it is not possible through intent to access the one in the front automatically), take a picture of it and show it.
While taking a picture I need different colours illuminating it. I've heard that this is possible in iOS with some versions of snapchat, which creates a "simulated" flash, illuminating the front screen in white. How could I manipulate this to get other colours?
I am experimenting on a Sony E4 dualsim, which is version 4.4.4. Don't know if that makes any difference at all... Would it also be easier to do it with iOS? Unfortunantely I do not have access to one, but this is a mandatory part of my project, so might be able to get some money to invest in a phone!
Thank you!
Guys, just seconds ago, I found, that there's the (from what I guess) new photo pro app from xperia 1 III is available here apkmirror.com
I tried to install and it worked!
Not able to take a screenshot as it's forbidden by system (not really necessary, sony). It has the new basic mode, that was shown on press release.
What are the differences with the mark II version? Difference in image quality or options?
From my guess, what sony is going to archive in future models, is to combine the normal and the pro-app, so there would be no need to develop and maintain two different apps - that saves money for them.
The linked app is already combined, some settings are slightly different insinde the pro-modes. You can switch to effects from basic-mode. I'm going to try to abandon the normal app and see, if the new one misses anything.
Thanks for posting that. I've tried it and it's great except that I normally open photo Pro in manual mode but this new app defaults to the basic camera app so you then have to change it to the camera pro app yourself. A small thing but just one more step that we didn't have previously when the two were separate apps. I see no setting to change how it opens by default so if anyone else does...
On a positive note, I may be imagining a slight thing but I think quality has maybe improved fractionally. To be specific, everyone has raved about this phone taking RAW files that you can develop yourself ( even though I think most flagship phones do now ) but I have always found that indoor shots with this phone in RAW always require a tripod which means you are just as well getting your real camera out. The ISO has to be low otherwise there is so much noise that even tools in lightroom struggle to fix it. But I think I see less noise now in handheld shutter speeds in low light.
But thanks to OP for spotting this app & bringing it to our attention.
BTW, how does anyone know this is the app from Xperia 1 iii when it's not released yet? Is there information on Sony website?
Many thanks.

I always open the Pro app with a push on the camera button. The new Pro app can be configured to open in Pro mode when pressing the camera button, so it works great for me.
Thanks very much. Ye, I saw you can choose the default in new settings too. I'm enjoying the new app.
Good find. Works well on the Xperia 5II as well.

The is a setting for "Open in last mode used". Since I always use the Pro Mode that works for me.
After installing the APK, can't choose the photo pro as option with camera key.
What I need to do to choose the photo pro as default?
Had to remap power button gesture to use the photo pro app. Camera button does not have photo pro option after installing this APK

That's what I've done too, with button mapper app. Howerver, it does not work when screen is off for my non rooted device. Don't forget to set photopro bypass in button mapper when photopro is active.
Tap tap app is also an interesting option.
For now I removed the update and reverted to the original Pro app.

So the old PRO app was not able to be used wiht the front camera, right?
Is there a way how to downgrade to original Photo Pro w/o root? I fear the answer is no.
It seems this upgrade broke eye AF at least on 70mm camera. All pictures of my wife and daughter focused on eye are out of focus. . Also manual object tracking seems not to work at all.

Yes, it's easy. Go to settings, apps. Find the Photo Pro app in the list, click on it. From the menu, choose "remove updates". That's it.

I really hope that Sony will provide the new photo pro app on our device with the Android 12 update...
https://forum.xda-developers.com/t/can-someone-dump-the-stock-camera-apk-pretty-please.4300387/ someone posted this IV used it on the 5ii works like if you hit camera button it opens the none pro version also has a wheel like basic mode this is from Xperia 1iii
