# WebCodecs API
This directory contains the Blink implementation of the [WebCodecs API](https://www.w3.org/TR/webcodecs/).
It provides low-level access to browser media encoders and decoders, both software and GPU-accelerated.
## Core Interfaces
The main IDL interfaces of the API and their corresponding C++ implementation
* **`VideoFrame`**: (`video_frame.h/.cc`) - A wrapper around `media::VideoFrame` for use in Blink and JavaScript.
* **`AudioData`**: (`audio_data.h/.cc`) - A wrapper around `media::AudioBuffer` for uncompressed audio data.
* **`EncodedVideoChunk`**: (`encoded_video_chunk.h/.cc`) - A wrapper for a `media::DecoderBuffer` containing a chunk of encoded video.
* **`EncodedAudioChunk`**: (`encoded_audio_chunk.h/.cc`) - A wrapper for a `media::DecoderBuffer` containing a chunk of encoded audio.
* **`VideoDecoder`**: (`video_decoder.h/.cc`) - Manages the video decoding process by calling `media::VideoDecoder`s.
* **`VideoEncoder`**: (`video_encoder.h/.cc`) - Manages the video encoding process by calling `media::VideoEncoder`s.
* **`AudioDecoder`**: (`audio_decoder.h/.cc`) - Manages the audio decoding process by calling `media::AudioDecoder`s.
* **`AudioEncoder`**: (`audio_encoder.h/.cc`) - Manages the audio encoding process by calling `media::AudioEncoder`s.
* **`ImageDecoder`**: (`image_decoder_external.h/.cc`) - Manages decoding of image formats (e.g., PNG, JPEG, GIF).
