SDR (Tone map from HLG to SDR in the backend)ĭevices that don't do not support HDR: SDR (Tone map from HLG to SDR in the backend) OEMs that add HDR support must support these formats, but can also support additional formatsĭevices support HDR (no HLG support only PQ): For user-generated content capture and playback, we require HLG10 to provide a consistent.For professional content playback, such as streaming movies, we require HDR10.To ensure consistency for developers and address key HDR use cases, we require OEMs to support aįew base formats on devices that support HDR: Transfer function, and color space handling. Which provides the core needs of HDR formats: 10-bit buffers, metadata (static, dynamic, and none), OEMs can enable any HDR format they choose with the Android HDR architecture, Note: HTTPS is not supported before Android 3.1. Protocol version 3 Android 4.0 and above.HTTP/HTTPS live streaming draft protocol:.The following network protocols are supported for audio and video playback: Lossless encoding can be achieved on Android 10 using a quality of 100. To minimize this audio/video drift, consider interleaving audio and video in smaller chunk sizes. For 3GPP, MPEG-4, and WebM containers, audio and video samples corresponding to the same time offset may be no more than 500 KB apart.For 3GPP and MPEG-4 containers, the moov atom must precede any mdat atoms, but must succeed the.Properly display Dolby Vision content on the device screen or on a standard videoīackward-compatible base-layer(s) (if present) to be the same as the combined Dolbyįor video content that is streamed over HTTP or RTSP, there are additional requirements:.Provide a Dolby Vision-capable extractor.Implementations that support the Dolby Vision decoder must follow these guidelines: Time and up to the maximum resolution supported by each codec on the device.
