H.265 reduces traffic by about 50% compared to H.264, so in some cases, it makes sense to use H.265 to transport the video to the server.
High-Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a standard for encoding video content and images. Compared to H.264/MPEG-4, the codec offers twice the compression while maintaining the same quality.
There are several cases where it may be helpful to use H.265 for the transport path to the server. Since there are currently no H.265-capable video players, the video stream must be transcoded to H.264 after it arrives at the server so that the video player can display it.
