How to implement RTMP/RTSP protocol for sending video to server ios(live streaming)?

Anybody know how to use FFMpeg for live streaming in ios? Where do I download the FFMpeg library from? Can somebody give some hint about where to start? I don't have any code in this question because I have no idea what to ask.

Upload file of huge size to server and track progress of uploading in iOS

I have a requirement in my application, to upload a file (pdf,audio,video, etc) to server with huge sizes. I need to upload the file in background and also indicate the user with a progress bar.
I tried to Google and found few stack overflow pointers to use NSUrlconnection and implement delegate methods.some pointed to ASHTTPClient. I am looking for best solution or readymade solution, if it is available. I am posting here, hoping someone might have come across a similar requirement and whose pointers would help me a lot.
Any pointers and if possible with code snippets is highly appreciated.
Thanks in advance.

Progress Bar in Google Drive Upload

Is there any way to create a progress bar for uploads to Google Drive?. I'm using the Google Drive SDK for Javascript. I can not find anything at all in their documentation.
Really appreciate it a little help.
I have consulted many codes, practically all I've found on Google during these weeks, but none show me the solution.
The last thing I've tried is webkitSlice, but really it seems a little crazy to implement that solution. I've tried and Google Drive I returns an error.
I find it impossible not to find any site with an upload with progress bar across the network.
The truth is that I'm going crazy with this issue. I have a website that is finished but without a progress bar can not see the light.
UF, thanks for your help.

What is the starting point for simple image indexing for search tool

I'm bulding a small photo gallery website and I need a function that detect duplicate images (don't need to be be 100% accurate, just like Google Image Search).
I'm using a very new language (Golang) so I don't think there is any available library for this out there.
So what is the starting point for me? Please give me some keyword about this. Or if you have any material that is simple and easy to understand, please share me.
I think this blog post is simple and easy to understand.

XML based image gallery in ios development help needed

I searched every where and tried to do learn from the Apple document, but did not success. Actually I learned to fetch XML, learned to Load Image, but not in the combined form.
Please suggest me some example if it does exist.
I came here by asking the same question, After some struggle I've found an interesting article by IBM:
http://www.ibm.com/developerworks/library/x-iosslideshow/
This should help you ( and me) to build the gallery.
If not just add it as a "Guide" on how to achieve that.
If I learn how to do it properly I'll let you know how.
Cheers,
Wolf
