wxcam-users Mailing List for wxCam

I found WXcam and like it. More features than Guvcview and less resource hungry than Cheese. I do have two questions (hopefully minor ones).

First: Is there any PDF documentation/manual about WXCam... settings, tweaks, etc??

Second: Is there anyway to add additional video effects?  For example - in Cheese, I can make my skin greenish like the "Hulk" in the movies.

   Hi, wxcam is now using alsa, but before 1.1 it was using /dev/dsp ... Are you using the last version?
   If you are already updated, it could be useful to post all the message that wxcam prints in the console (start it using a terminal)

Hello, i'm using an easy cap video capturer pluged into a ps2, and i'm using your software to use the playstation with my laptop screen. The problem seems to be that for some reason i can't get any sound, the picture is great and fluid. I could only get sound with "Vlc" but the image was laggy so i can't use it. If you could help me I would apreciate it.

Thank You

Felix

hello i'm from argentina
i recently bought a Banana Pi mini pc
i want it to run a Lubuntu system
it works with the wxcam?
it has a short or a long delay with the video in the screen?
congrats for your software and thank you

Hi Folks,
                I have installed WXCAM on Mint 17 32Bit and it works
fine with the Video Movement Detection.  But would like to know how I
can get Snapshot/image/picture to save a single image with Movement
Detection.
 
Thanks,

with cordial greetings and thank your work and great contribution to 
free software, I need to know if you can help with the following error

Dear wxcam developers,

I have installed wxcam on ubuntu saucy 13.10, and got it working with a
couple of tweaks here and there.
it's by far the best cam app out there and I'm oldschool when it comes to
that. ( if it works don't change it)

I recently upgraded to ubuntu trusty 14.04
and wxcam has issues with trusty.
I tried reinstalling wxcam and the error I got was libmjpegtools 19 >=
required in short!
went to the software centre and the version installed is version
libmjpegtools 2.

*tried fixing it by compile/build the package myself with some good ubuntu
forum help (thanks: TOZ):*


*install build essential packagesCode:*

sudo apt-get install build-essential


*install wxcam required packagesCode:*

sudo apt-get install libwxgtk2.8-0 libwxgtk2.8-dev libxvidcore4
libxvidcore-dev libv4l-dev cimg-dev libmjpegtools-dev libasound2-dev
libgtk2.0-0 libgtk2.0-dev libglade2-dev intltool




*The 64-bit fix was not needed.download the source from
http://sourceforge.net/projects/wxca...ar.gz/download
<http://sourceforge.net/projects/wxca...ar.gz/download>prepare, build and
install the packageCode:*

tar xzvf wxcam-1.1.tar.gz
cd wxcam-1.1
./configure
make
sudo make install


*execute itCode:*

wxcam

*when entering wxcam at the end I got this error*

Hi all,

just joined this list. Trying to use my 64bit laptop with wxcam but I've got
openSuse on it and the libraries required are all over the place and all sorts
of different names. Can anybody reccomend a distro which is an easy target for
building the 64 bit version on?

I get an dependancy error:
libasound2(>> 1.0.24.1)

I use ubuntu 2.6.32-42 generic pae and I just did an apt-get  update
now its version 1.0.22

any suggestions

Thanks

Hey guys, what's up? :-D
I wanted to tell you that we´ve developed a few filters that work perfectly
on HD webcams, using SSE assembler on amd64 architecture.
I`d like to commit those changes to the repo for you to test them and, if
you like them, add them to the main software branch =)
Just let me know and I'll send you the source code and instructions for
compiling. It's really easy, you just have to install nasm and configure it
on netbeans.
best regards
galimba

I change /dev/video0 to /dev/video1, click OK, it tells me the application
needs to be restarted but when it starts up, it's looking for /dev/video0
again.

Hi wxcam developer!

You might be aware that wxcam is not compatible with famous Raspberry Pi
(Raspbian):
http://www.raspberrypi.org/phpBB3/viewtopic.php?p=113506#p113506

The problem is with libmjpegtools-dev dependency, which is not in the
Raspbian repo.

May be you can suggest some good solution or some change in the source code
to
allow wxcam run on standard Raspbian?

Thank you for excellent software,
Danil

how can I change the format** to 320x240, 160x120 or 80x60

for this project a minimum frame rate 16fps is probably required…

if I change format by deleting and typing, I get error message: 

frame height is 240 but image height is 480.

How do I change the Image height?

regards

Jonathan

**640x480 wxcam wfm Arch on Raspberry Pi the frame rate is low  ~1-2fps

Hi Team,

We are working on wxcam application for displaying the remote video, We 
want to disable the local video display and want to display the remote 
video,which part of the code i really need to comment to disable the 
local video and at the same time i want to render the remote video on 
the GUI.

We will be highly thankful to you since we are not able to understand 
your event based code clearly.

Hi All,

             Wxcam application is used to display local rendering video.In my application I am using wxcam to rendering remote video.
             I wanted to know in wxcam which buffer is used to copy the video content.If you can give us the call flow of function it will
             be helpful for us.

Hello!
Thanks for the response!
It's solved (!!) :-)

I'm now compiling the assembler sources and linking everything without
problems.
We figured that it was generated by NetBeans, and so we downloaded it and
loaded the project. At first I was sort of against using NetBeans... I'm
sort of a dinosaur who uses vim+command line, but in the end: I have to
admit that NetBeans is a pretty confortable IDE.

Poking around the NetBeans 7.1.2 configuration I was able to add and
compile the assembler code. It didn't take much efford, tho I had to change
the way the ASM functions were declared inside the headers because netbeans
uses g++ and the SSE functions we're generating have to be interpreted as C
functions.
A simple declaration was needed: *extern "C" {void asm_function();}* for
every assembler function.

Thanks again!
ttyl
Sebastian
