H.264 (MPEG-4 AVC) and H.265 (HEVC) exist as codecs that are standards for video compression. However, both have complicated licensing issues, and the disadvantage was that they would have to pay a high licensing fee in order to adopt them for products and services, and as a result, prices for products and services would also rise. AV1 is royalty-free, but the compression efficiency is 20% higher than the conventional VP9 .
Netflix basically uses H.264 as the codec, and since 2016, it has also adopted VP9 as a download function on smartphones. In 2018, we are optimizing codecs .
The AV1 decoder used in the Android application is dav1d developed by VideoLAN , and it is said to be optimized to play Netflix 10-bit color compatible content.

However, although the AV1 has a small playback load, it has the drawback that the computational cost for the encoding time and compression ratio is enormous, so hardware support is also very important for the development of the AV1.
