What is FLV?

FLV (Flash Video) was the standard format for web video streaming before the rise of HTML5 video.

What is MJPEG?

MJPEG files are built around lossy compression. Designed for security cameras, ip cameras, digital camcorders, they use the video/x-motion-jpeg MIME type and typically range from varies by content.
