openframeworks

Error LNK1104 cannot open file ';.obj' project1 D:\project1\source\project1\project1\LINK 1 I'm using visual studio 2015 and openframeworks, I'm fairly new to the c++ language. I couldn't find a line of code which refers to this file. Has anyone had a similar error or does know any tips to find the cause of this error? The build-process has two main step: compile link In the compiling stage the obj files are built from the source file. In the linking step these obj files are "concatenated" resolving unresolved references and builds the final output (static/dynamic library or an executable).

I am having Xcode 4.4 on OS X Lion. I'd like to install the Mac 10.6 SDK - also known as macosx10.7 SDK - because I need to compile openFrameworks. I found that I need to download additional tools from this site . However I didn't find any 10.6 SDK there. I also tried looking in Xcode Preferences -> Downloads -> Components, but there is no way. I am wondering how can I install previous SDKs for Xcode? Rob Napier Unfortunately, Apple tends to make this much harder than you'd like. You can't download SDKs by themselves. They come as part of specific versions of Xcode. So you have to download the

I am trying to get an interpolation of one color to another shade of the same color. (for eg: sky blue to dark blue and then back). I stumbled upon some code that could be used if the range was from 0-255 or 0-1. However, in my case, I have the RGB codes for Color1 and Color2, and want the rotation to occur. Color 1: 151,206,255 Color 2: 114,127,157 Any ideas how to go about this? hyde I suggest you convert RGB to HSV, then adjust its components, then convert back to RGB. Wikipedia has an article about it, and it's been discussed here before: HSL to RGB color conversion Algorithm to convert

I understand that this is a very open ended question. I have done some initial reading into FFmpeg , but now require some guidance. Problem I have a video input.mov . I would like to overlay another video on top of overlay.wov . The result should be a single video ( output.mov ). Notes Done some initial reading into FFmpeg and read this question . Thanks - C. Edits Backend is Go/Ruby. Open to using a new language. The audio from the first video should be kept. Setting the interval at which the overlay starts would be great. Current Solution ffmpeg -i input.mov -i overlay.mov -filter_complex "

I am writing a program in C++ and openFrameworks that should hopefully implement an image retrieval system by colour matching. I have got an algorithm to find the match in a database by an rgb value. For example, if I have a database of 1000 pictures on my computer and I have a query rgb value 255,0,0 the program would look through 1000 pictures and find the closest match. However, my problem is that I want it to also look for the match on the web. I have been trying to find how to get images from websites, however, if you don't know the specific url of the image it's hard to get hold of the
