I want to display on the iPhone screen video stream RTSP. Can throw the source code of the project or details on how to implement it. Found 2 project, but they have not compiled:
https://github.com/mooncatventures-group/RTSPPlay
https://github.com/mooncatventures-group/RtspFrames-test
Source code from the site VLC also does not compile, no files.
Tell me, is it possible to record the stream to a video file? And how is it implemented?
Thanks in advance.
You can use FFmpeg for displaying RTSP video stream.
As example you can look at my project hosted on github.
It's movie player for iOS using ffmpeg and OpenGLES.
For me appears that the best choice is
https://github.com/durfu/DFURTSPPlayer
Yes, it's pretty old and it won't work out of the box, but if you'll update mpeg libraries to 3.0, refactor project to ARC and get rid of deprecated mpeg methods, it seems to be a good choice. Definitely better than VLC.
All above can be found here https://github.com/rozum-dev/DFURTSPPlayer

Now I try to record audio in browser in small pices by RecordRtc js library.
What I've explored for this moment:
Inspite of what codec and format I point in RecordRtc options Chrome want to record only webm;codecs=opus audio, Firefox want to work only with ogg and only firefox know what the ogg is this, my android-mobile-webview records wav (I haven't checked Ff, but chrome is definitely not gonna work with wav)
Is there any crossbrowser solution in this branch? maybe I just need to explore another js recorders? Or I have to be prepared to recode every formats from one to another by my hands if I want to unify audio format in my project.
I event cannot find any generalized information about what codecs-browsers supporting pairs there are.
Next I'm gonna send these blobs to another user one by one and than play it by MediaSource.souresBuffer that of cource have pretty much differences in its way to work in defferent browsers too.
May you share any experience or good practices in all this browser-audio-recording stuff with me?
I alredy have been checking different combinations of borwsers and codecs, talking with chatgpt about possible solutions, but it only advice to checking codecs suppornig by methods like MediaRecorder.isTypeSupported and recoding audio by ffmpeg.js if sth wrong.

Can an augmented reality DESKTOP application be made on Unity or any other 3D engine using a webcam.? if yes, then what other extra tools and softwares are required?
Yes you can create AR apps using Unity. I prefer using ARToolKit as it is open source. Have a look here for necessary downloads: http://artoolkit.org/download-artoolkit-sdk (scroll down to the "Download Unity Section")
Here you can find the documentation for using Unity with ARToolKit:
http://artoolkit.org/documentation/doku.php?id=6_Unity:unity_getting_started
Vuforia does not support desktop for now. But artoolkit support.
And easyar supports.
Of course it can be done using Unity, take a look at ARToolkit, there are also a dozen of other tools.
Here you can find an old post about the subject.

I want apply effect to video from camera roll.
So, I use GPUImage. By the way, I can't build GPUImage project with error.
Error is "OpenGL/OpenGL.h" not found.
I use Xcode5.0 with Mac 10.8.5. I want compile GPUImage project for iOS7.
or do you know another way?
If you're getting an error about OpenGL.h in an iOS project, you're using the wrong side of the framework. You're somehow trying to include the Mac port of the framework in your iOS application. Don't do that.
Instead, follow the step-by-step instructions under the section "Adding the framework to your iOS project". These guide you through adding the iOS framework to your project. You could also look at the various sample applications that come with the framework to see how this all works.

Does anyone know how to make a movie (avi / mpg) thats uploadable to YouTube from a series of PNG images? Also, how would I add a .caf audio file to that videostream?
There are plenty of libraries like x264 to do this type of thing for you, but you'll probably need to use a library. Video encoding is not an easy task.
I'm pretty sure you can do it with ImageMagick which has been ported to the iPhone Try the 'convert' command. (I haven't done this myself, so you might need to do some research on the latest iPhone port and how to use the command.)

I'm writing an iPhone app where I'd like to display some simple musical notation (just a chord or two).
This question is a call for suggestions on the quickest way to go about it. For instance:
Is there any iphone OR objective-C libraries for doing this that I'm missing?
Are there any examples of open-source objective-C software in the wild I could look at? It wouldn't have to be iPhone specific.
If there isn't any objective-C code to do this, anyone know of any musicial-notation rendering software in other languages?
Indeed, MusicKit is an audio tool, not a symbolic tool like you need.
I don't know of any open-source Objective-C music notation programs. However, the recently-released Zong! Viewer is an open-source (GPL) Java program. You can't run Java on the iPhone, of course, but it might give you some ideas for structuring your software. MuseScore is an open source music notation editor that might provide more ideas.
So far the only iPhone music notation application I know is pocketscore. It has the great idea of exporting MusicXML files via e-mail so you can work on your music later with a more full-featured program than you can write on an iPhone.
There might be other open source programs you can check out on the MusicXML software list. Good luck!
This is an objective-c music analysis framework which may have what you need:
