Hardware encoder on Surface Pro X

Question

According to docs https://www.cpu-monkey.com/en/compare_cpu-qualcomm_snapdragon_microsoft_sq2-1850-vs-qualcomm_snapdragon_microsoft_sq1-1805 MS SQ2 (Adreno 690 GPU) has support for hardware encoding to h264, hevc and vp8. Where we can find the API? I've Surface Pro X and in Task Manager I see that GPU has Video Encode, but I can't use it. I would like to see the API that would have allowed me to encode h264 on SPX. Video Decode can be done using DirectX, so I'm asking only for encoding. It could be useful for libraries like ffmpeg (currently, ffmpeg on Surface Pro X supports only software encoder).
