Obtaining Media File Information in Visual C++ Using FFPROBE

A short demonstration on how to utilize the ffprobe command to extract information about media files such as wav / MP4 files.

The ffprobe executable comes with the complete ffmpeg package and can be obtained from here:


Once downloaded and installed, the ffprobe executable resides alongside the ffmpeg and ffplay executables as shown:

Serializing data in MFC / Visual C++

This post shows you how to utilize the built-in file handling capabilities that MFC has in order to serialize your data, that is, how to read from or write to a disk.

Using the MFC document object

One way is to use the MFC document object to do the serializing for you. This will be demonstrated by creating a simple SDI (single document interface) using the AppWizard.

Select File > New > Project and select the Visual C++ > MFC Application as the choice of installed template:

Using boost::property_tree

Some short examples of how to use the Boost property tree in order to read from and write to XML files.

Reading XML into a Boost property tree

Here’s how to read an example XML into the Boost property tree and traverse each of the the “item” sections within this XML, given that items may contain differing subsections:

For this XML example file “test1.xml” I use the following example XML taken from the Microsoft MSDN page:

Using a subset of the boost libraries in Windows

For many C++ applications I very much want to use the Boost libraries, just not the whole set.

This post explains how to use the bcp tool to create a subset of the Boost libraries in order to leave out unnecessary libraries and tailor it to the needs of your project. One nice thing about bcp is that it can be run at any time so as to update your Boost dependencies as and when the need arises.

Converting a SYSTEMTIME to a std::string in C++

A short recipe outlining how to output a SYSTEMTIME value as a std::string.

The example format will be “YYYY-MM-DD HH:MM:SS.MMM”

I specifically wanted to include milliseconds.

In this example I employ three possible techniques:

1. MFC CString
2. std::ostringstream
3. sprintf

Using boost::filesystem

Examples of using boost::filesystem for various things as and when I encounter them…

Many have been lifted from the StackOverflow site.

For reasons of brevity and clarity I generally avoid extraneous code such as exception handling etc in these examples and just focus on the techniques themselves.

1. Copying a directory

This recursively uses boost::filesystem::create_directory to create a copy of a directory including its contents, sub-directories etc.

For example the MyStuff folder:


Use the following code snippet to re-create a copy of the MyStuff folder, and rename it MyStuff2:
