Should work with all resolutions. 16bit is only transport layer.
Dispmanx is saving snapshots to 16bit RGB (RGB565) and then VNC is setup to use RGB555. So only shifts in VNC server can be problem.

And one comment. Tested only headless with TV out as display.

Hello. I have been playing with dispmanx_snashot and using LibVNCServer and created a simple VNC server. It takes snapshots from screen via dispmanx and sends them via VNC. It can also view the 3D demos from hello_pi. The code is here: https://docs.google.com/file/d/0B0ImsXFDXpRBYkthTHMzWlRQUWc/edit...

Hello

I am interested in Wayland/Weston. I am looking in raspbian repositories and can't find weston. Wayland is there, but weston not.
I know that weston now has raspberry pi backend so I want to try.

I am doing something wrong?

Hello. That was the same resolution. But on framebuffer there is overscan. So I get only 656x416 resolution and on the border is black. But when I snapshot it with dispmanx_snapshot I get the full resolution of TV and it is 720x480. The screenshot were taken in 10s distance. So first I saved dispman...

Hello. I have created utility to save snapshot of screen via dispmanx_snapshot. See thread: http://www.raspberrypi.org/phpBB3/viewtopic.php?p=376546#p376546 Now I have tested it and saved screenshots of terminal, xwin and 3d demos with it. Then I looked into pictures closer and I see that characters...

Hello.

I am planning to do some kind of window manager and I plan to combine OpenVG and OpenGLES2.
My idea is to render OpenVG commands to OpenGL texture and display this texture with EGL/dispmanx.

Does someone knows an example of this. Is this possible to do?

hanzelpeter

Hello.

I have got it running. Great app.
Do you have some other examples of functions?

I am not good in math.

Thanks.

Hello. I have installed games from PiStore (openarena, etc). Now I am running little out of space. I looked on filesystem and found that in: /var/lib/indiecity/pistore/Installers are the downloaded installers for games. And in /usr/local/bin/indiecity/InstalledApps are installed games. How I can del...

Hello. I just started to use dispmanx to draw content on screen. I followed hello_pi/hello_dispmanx.c So I've got my picture on screen and now I need to update that picture. I have used vc_dispmanx_resource_write_data to write picture to element. But how I can i update the element to show next frame...

hanzelpeter

I think they are both right. If you have black borders around text try disable_overscan=1 in config. Then tvservice and fbset should report the same. I think this is all about overscan.

Hello all.

I have found a solution. It is all about using Menu on LCD monitor and turning off AV Mode.
See this: http://www.overclock.net/t/579884/samsu ... n-problems

So now I am very happy. I have crystal clear texts in console.

Hello.

I have resized the SD Card. I am using the same RPi and same SD card in my work office and at home.
So now I have succesfully installed and runned OpenArena on the same SD card.
So the size of SD card was not the problem.

hanzelpeter

Hello.

Just try it on my LCD monitor with mouse and keyboard and Openarena is working !!!.
Yes. so now only to be curious why download in my work office is not working.
We have switched off all firewalls rules and then also direct connect without firewall and download was not working.

Peter.

Now returned to my home computer whichone I used for registering with indiecity and tried to run PIStore. Now t magically works. (also My Libraty, profile and download) So I downloaded OpenArena succesfully on my home setup. Tommorow will see if it also runs. (as I have no monitor for RPi at my lapt...

Now I have played with PIStore. Removed via sudo apt-get remove pistore, deleted /home/pi/indiecity and also /var/lib/indiecity. And than reinstalled pistore and now I cannot even browse My Library.

Hello. I have successfully installed PI Store and I want to download and install OpenArena. But I have a problem. I can succesfully login into PiStore and added OpenArena to download, but donwload is not starting. Do someone know on which TCP port download is working? I can see details, browse PiSto...

hanzelpeter

Hello.

I am stuck. On my LCD monitor the disable_overscan=1 makes my command line moved to left and bottom and I can't see login prompt.

Can disable_overscan=0 and overscan_left be combined?
But also with disable_overscan=1 the text console is not "crystal" clear.

Any ideas?
Thanks.

hanzelpeter

Hello. I have a question about HDMI/TV resolution and default size of framebuffer width/height. My setup HDMI LCD Monitor: tvservice -s = 1920x1080, fbset reports 1824x984 TV with NTSC: tvservice -s = 720x480 fbset reports 656x416. My problem is that on HDMI LCD monitor the console text is not cryst...

Hello. I have been searching on internet for overview of BCM SoC of raspberry pi but can't find something usefull. I saw that raspberry pi firmware is now open-sourced, but there is still some BLOB as closed source. And my question is where is this blob?. Also for OpenGL this libGLES is passing comm...

Hello. I have some crazy setup for my RPi. I have only notebook and TV card inside notebook. I connected RPi to notebook via cross ethernet cable. I can connect to RPi via SSH.

Hello. I am thinking of buying RPI, but at first I am looking on some window system on it. I know RPI has OpenGLES and EGL support. Is there some window system that can run on top of firmware's EGL and GLES? I checked wayland source code and I don't think it will run. Or can someone point me to pure...
