YouTube generally play video through two separate files, one have video frames but no sound, another have just audio tracks. So I believe maybe there's a way to make WebM videos able to hear, that is, use two separate recording methods to get video frames and audio tracks, then inject audio into WebM.

Note it's not possible to capture directly as PNG - the JPEG data comes direct from the camera driver (although possibly this could be done by requesting data in YUV_420_888 format). if I use YUV_420_888 format to get a lossless result, there wouldn't be any HDR info to add to the PNG result). To my eyes, such circumstances should be documented in Open Camera Help. I think UltraHDR is only currently supported via JPEG and HEIC formats, so there's a gap here If this is right, and could be reproduced...

The official PNG specification also added HDR support, making it possible to interchange HDR information with other image formats. https://www.w3.org/TR/png-3/

On this page I saw there is the following description: Note that a particular mobile device might support additional formats or file types that are not listed in these tables. In addition, if you use a MediaCodec directly, you can access any of the available media formats regardless of the supported file types and container formats. If Open Camera supports MediaCodec API it's possible to provides supports for more media formats, and cross over some technical limits, e.g. WebM without sound.
