Is it necessary to convert uploaded files to FLV format for online playback?

Converting uploaded files to FLV format is not necessary for online playback as there are many modern video players that support various file formats. To ensure compatibility with most devices and browsers, it is recommended to use HTML5 video player with fallback options for older browsers. This way, users can upload videos in different formats and the player will automatically handle playback. 

// HTML5 video player with fallback options
<video controls>
  <source src="video.mp4" type="video/mp4">
  <source src="video.webm" type="video/webm">
  <source src="video.ogv" type="video/ogg">
  Your browser does not support the video tag or the file format of this video.
</video>
