The purpose of this app is to upload an mp4 video format and convert it into an mp3 audio format. You might see this feature online, those online video converters. But today, we will create a desktop application, not a web application.
MP4 is a new popular format for video and audio. Converting an MP4 file into an MP3 file converts the audio portion of the MP4 into an MP3 file. For example, you have a movie file in MP4 format. You want to separate its background music and store the background music as a file. You can use this tool to convert the sound portion of a video file.
MP4 and MP3 are popular video and audio file formats. Sometimes, you may need to extract the audio from an MP4 file and convert it into an MP3 file for compatibility or editing purposes. FFmpeg is a powerful tool to do this, but it can be intimidating for non-technical users.
HI I have always use realplayer to download videos from you tube and then convert to MP3 now the videos are actually downloading as MP4 and when you try and convert them to MP3 realplayer asks you to upgrade and again as the other person I dont really want to. Some videos still download as flv but some come as MP4.
