WebCodecs API

This directory contains the Blink implementation of the WebCodecs API. 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::VideoDecoders.
  • VideoEncoder: (video_encoder.h/.cc) - Manages the video encoding process by calling media::VideoEncoders.
  • AudioDecoder: (audio_decoder.h/.cc) - Manages the audio decoding process by calling media::AudioDecoders.
  • AudioEncoder: (audio_encoder.h/.cc) - Manages the audio encoding process by calling media::AudioEncoders.
  • ImageDecoder: (image_decoder_external.h/.cc) - Manages decoding of image formats (e.g., PNG, JPEG, GIF).
