Approach to HDR and Tonemap on Android

At Meta, we deeply invest to ingest and playback with the best media quality for our users.

This becomes especially challenging with the advancement in camera capture capabilities of new devices and products such as Reels that allow users to add special effects on top of these videos.

As the HDR color space evolves on Android with different OEMs supporting different HDR formats, at Meta we need to correctly read these formats and apply the appropriate tonemap(conversion to SDR) so that such videos are not busted on upload and playback.

Video Client Infra has solved the challenging problem to correctly tonemap different format HDR videos on Android devices, at a frame level. This helps to preserve the media quality, minimum latency impact and keeps these videos still compatible with all the awesome effects loved by our creators.

We also plan for HDR transcode and ingestion, as the HDR format is standardized for all OEMs.
