Abstract: This registration is entered into the [[webcodecs-codec-registry]].
It describes, for VP8, the (1) fully qualified codec strings,
(2) the codec-specific {{EncodedVideoChunk}}
{{EncodedVideoChunk/[[internal data]]}} bytes, (3) the
{{VideoDecoderConfig/description|VideoDecoderConfig.description}} bytes,
and (4) the values of {{EncodedVideoChunk}} {{EncodedVideoChunk/[[type]]}}.
The registration is not intended to include any information on whether a
codec format is encumbered by intellectual property claims. Implementers and
authors are advised to seek appropriate legal counsel in this matter if they
intend to implement or use a specific codec format. Implementers of
WebCodecs are not required to support the VP8 codec.
This registration is non-normative.

Fully qualified codec strings {#fully-qualified-codec-strings}
==============================================================
The codec string is `"vp8"`.
EncodedVideoChunk data {#encodedvideochunk-data}
================================================
{{EncodedVideoChunk}} {{EncodedVideoChunk/[[internal data]]}} is expected to be
a frame as described in Section 4 and Annex A of [[VP8]].
VideoDecoderConfig description {#videodecoderconfig-description}
================================================================
The {{VideoDecoderConfig/description}} is not used for this codec.
EncodedVideoChunk type {#encodedvideochunk-type}
================================================
If an {{EncodedVideoChunk}}'s {{EncodedVideoChunk/[[type]]}} is
{{EncodedVideoChunkType/key}}, then the {{EncodedVideoChunk}} is expected to
contain a frame where `key_frame` is true as defined in Section 19.1 of [[VP8]].
Privacy Considerations {#privacy-considerations}
