1849321 - Implement 2.2 of VideoDecoder#Decode: check if the data passed in is a key frame when it's required, and throw synchronously

Status: NEW

(Core :: Audio/Video: Web Codecs, task)

Description

[Paul Adenot (:padenot)]

https://w3c.github.io/webcodecs/#dom-videodecoder-decode, 2.2 reads:

Implementers SHOULD inspect the chunk’s [[internal data]] to verify that it is truly a key chunk. If a mismatch is detected, throw a DataError.

As a reminder, SHOULD means:

3. SHOULD This word, or the adjective "RECOMMENDED", mean that there
   may exist valid reasons in particular circumstances to ignore a
   particular item, but the full implications must be understood and
   carefully weighed before choosing a different course.
