If you feel you need to dive into further detail, Udemy has a great online course on Encoding for Multiple Screen Delivery by Jan Ozer from Streaming Learning Center. If you want to learn more, a few more fundamental concepts are covered in the following posts in this series: To learn more about containers and the role they play in streaming, check out our post on adaptive streaming. You now know how Codecs work and how container formats differ from video formats. More examples of containers are shown in the picture below. The flash container could also hold video encoded with vp6 instead of H.264. Flash (.flv) is a container format that utilizes H.264 for Video and AAC for Audio. One of the biggest sources of confusion about video is not realising that the file format (aka container format) is completely different from the video format (the video codec). The process of changing the container format of a file for delivery to a different target platform is called transmuxing. If you want to change the way the data is being read, you can swap out the container without changing the file type. It defines how the video, audio and other data is stored within the container. The figure below depicts the creation of an encoded video file from original video and sound files.Ī Container or wrapper format can literally be thought of as a container for the actual video. For example, YouTube live player accepts only H.264 video codec. Different players accept different types of codecs. Common video codecs (also called video format) include MPEG-4/H.264 and WebM(VP8). Audio and Video CodecsĪ Codec is technology used to compress the data. This post is a part of our educational series on Live Streaming Basics for the Newbie and Video on Demand Basics for the Newbie.
