Lyrics Video Creator is one of my favorite software projects that I've ever done! The software was developed for Windows using C# and WinForms. The main goal of the software is the creation of karaoke videos. We used the FFMPEG library to get quality videos. Audio file processing is implemented using of NAudio library.
Karaoke software technical solutions
The most important requirement for a Lyrics Video Creator is a good high-quality video and sound. We had to provide really good quality for users because many of them use karaoke videos on smart TVs.
Video processing in karaoke software
Modern smart TVs provide very high resolutions and our karaoke software has to provide at least 4K video. On the other side, video processing should not take too much time.
I have chosen the FFMPEG library for video processing in this karaoke software. FFMPEG has GNU 2 license, we have not to pay for his using. FFMPEG has good documentation and many developers use it and share their experience on the Internet. This library provides good quality and speed at the same time.
All video processing inthis karaoke app was done using FFMPEG as an external library, managed by command line scripts. I have done several projects using this approach before. This solution looked good!
Audio processing in karaoke software
Reading and processing of audio streams in karaoke software was done using NAudio library. This is an old but very reliable solution. I'm using NAudio in many of my projects.
Users interface in Lyrics Video Creator
Using the software is very easy and comfortable. The user has to provide lyrics and an audio file. Lyrics may be loaded from a file or typed in manually. Sound stream uploads from the music file. There are two types of backgrounds available: static image or video background. The software has many settings including settings for result video and animation.
Lyrics markup by time marks is the final step before video creation. The user can save all data in the project file and continue working on it next time.
Development of the app required many hours, but the result looks so good!
