I'm making an application in Qt to show bitcoin charts (perhaps to trade in the future as well).
I want it to be presented in the traditional OHLC (Open High Low Close) format.
So far the only ways I found to chart the price data was in Python (and not easy to update in realtime at all). Anyone knows a good chart library for C++/Qt that I can use here?
I see Qt, has Qt charts, but that's a paid library and I want my project to be free.
The QCustomPlot library can create OHLC and candlestick charts:
The class you're looking for there is the QCPFinancial plottable. For realtime display, you can change all the data with setData(...) and access or modify existing values with the data() method.
I've used QWT for live charts in biomedical applications and liked it a lot.
http://qwt.sourceforge.net/
It has a trade plot class you could have a look at:

I am looking for a API/web service for me to retrieve a list of landmarks, points of interest (and their GPS coordinates) near a given city. I tried google places including the query Place Search and type point_of_interest, but the results do not seem satisfactory.
For example, to Paris, I need an answer:
Eiffel Tower, Arc de Triomphe, Champs Elysees, ...
What would you advise me to find such information.
A couple options:
Foursquare Venues Platform
Factual Places API
Google places has the flag "point_of_interest" but only to show, not for search (see Table 2 in https://developers.google.com/places/documentation/supported_types)
Google Earth on the other hand has what you need. See the icons for Tourist destination, Monument and Historical Place in https://support.google.com/earth/answer/180709?hl=en#what
However I am not sure if there is an API for this data, or if you need to find a way to extract it from GE.

I am looking for a library to record images from a webcam and sound from the microphone and generate a video file (avi, mpeg or any other format).
I would prefer a cross-paltform solution (Windows, MAC and Linux) and something in C/C++ or Python.
Any recommendation and/or sample code?
Update: Folowing #Rory reccommendtation, i found this example of webcam viewser with Python and gstreamer. Unfortunately it requires v4l2src plugin which is not provided (correct me if I am wrong) with the Winodws build. Which plugin should be used on Windows?
gstreamer is an open source multimedia framework with C & Python bindings.

I am looking for an online file conversion site which converts DOCX, DOC, PPT, PDF etc. to JPG files using an API (RESTful etc.).
I do not mind paying for the service but am unable to find an such service online.
One that might work for you is convertapi (http://www.convertapi.com/).
I recently used this to enable the following conversions for an app :
doc/docx --> PDF
ppt --> jpg
doc/docx --> jpg
They have a very simple REST api that's easy to implement : (http://www.convertapi.com/api/word-pdf-api)
You probably should also have a look at the CloudConvert API, which, as far as I know, supports your mentioned formats.
Convertapi doesn't do ppt --> jpg at the moment.
