Render frames concurrently

Hello!
As far as i can see, it is not possible to render multiple frames concurrently when transcoding a video.
Is it on the roadmap to support concurrency? Or did anyone implement anything in this direction?
Thanks for your help.

Start by reviewing LiTr's transcoding pipeline and the points where video frames are rendered. Determine whether concurrent frame rendering is feasible with the existing Android hardware-accelerated design, then define completion criteria around safely rendering multiple frames concurrently without breaking output or ordering.
