Error 142 Age Of Mythology Extended Software To Enable

Initially, limited and well-nested, the standard is now very broad and evolving in various directions.

In all these cases, prior to being delivered through our content delivery network Open Connect, our award-winning TV shows, movies and documentaries like The Crown need to be packaged to enable crucial features for our members.

In this post, we explain these features and how we rely on award-winning standard formats and open source software to enable them.

The output of an encoder is a sequence of bytes, called an elementary stream, which can only be parsed with some understanding of the elementary stream syntax.

For example, detecting frame boundaries in an AV1 video stream requires being able to parse so-called Open Bitstream Units (OBU) and identifying Temporal Delimiters OBU.

However, high level operations performed on client devices, such as seeking, do not need to be aware of the elementary syntax and benefit from a codec-agnostic format.

The packaging step aims at producing such a codec-agnostic sequence of bytes, called packaged format, or container format, which can be manipulated, to some extent, without a deep knowledge of the coding format.

At Netflix, we strive to provide an experience where you never see the lips of the Queen of England move before you hear her corresponding dialog in The Crown.

They rewind and replay their favorite chess move in The Queens Gambit.

They skip introductions and recaps when they frantically binge-watch Lupin.

They make playback decisions when they watch interactive titles such as You vs.

Wild. Due to the nature of the audio or video compression techniques, a player cannot necessarily start decoding the stream exactly where our members want.

Under the hood, players have to locate points in the stream where decoding can start, decode as quickly as they can, until the user seek point is reached before starting playback.

This is another basic feature of packaging: signaling frame types and particularly Random Access Points.

Adaptive streaming technologies require that streams of various qualities be encoded to common constraints but they also rely on another key feature of packaging to offer seamless quality switching, called indexing.

Indexing lets the player fetch only the corresponding segments of the new stream.

Decryption modules need to be initialized with the appropriate scheme and initialization vector.

Hardware video decoders need to know in advance the resolution and bit depth of the video streams to allocate their decoding buffers.

Being able to signal all these elements is also a key feature of modern packaging formats.

Reducing the friction when on-boarding a new device and making sure that our content will be playable on old devices for a long time is very important.

The ISO Base Media File Format (ISOBMFF) is the key packaging standard in the entertainment industry as recently recognized with a Technology Engineering Emmy Award by the National Academy of Television Arts Sciences (NATAS).

Streams encoded with well-established codecs such as AVC and AAC can be carried in ISOBMFF files, but the specification is also regularly extended to support the latest codecs.

The Media Systems team at Netflix actively contributes to the development, the maintenance, and the adoption of ISOBMFF.

As an example, Netflix led the specification for the carriage of AOMs AV1 video streams in ISOBMFF.

Figure 2 illustrates the complexity of ISOBMFF today through the concept of brands, a concept similar to profiles in audio or video standards.
