Understanding H264 and DASH file formats

The H264 format, also known as AVC (Advanced Video Coding), is a widely used video compression standard. It is known for its high-quality video output and efficient compression, making it ideal for streaming and storage. On the other hand, DASH (Dynamic Adaptive Streaming over HTTP) is a streaming format that allows for adaptive bitrate streaming of multimedia content over the internet. DASH enables smooth streaming by adjusting the video quality in real-time based on the user's internet speed.
