HDR Media Capabilities
Image HDR support coming to Firefox?
MediaCapabilities? implementations are missing features needed to check for feature/playback support on a variety of platforms.
- HDR fields currently ignored by Chrome (seems to be in the works https://chromium-review.googlesource.com/q/MediaCapabilities)
- WebKit? sights fingerprinting issues (Chrome uses `powerEfficient: false` for configurations that require software decoding)
- Dolby needs to join the W3C? to make and move proposals forward
- on PS5?, decodeInfo calls fail after more than 25 calls (synchronous or for the lifespan of the app?)
- What is the state of `transition` support detection? https://github.com/w3c/media-capabilities/blob/main/explainer.md#transitioning-between-stream-configurations
Example use-case
- Badging for DolbyVision? profile 8 metadata usage requires decodeInfo to expose whether `hdrMetadataType` that maps to HLS SUPPLEMENTAL-CODECS attribute is supported (vs ignored).
Should issue be filed here https://github.com/w3c/media-capabilities/issues ?
