Why is h.265 so difficult to popularize?

Because the high licensing fee is unbearable for hardware manufacturers. If mobile phones, televisions, tablet computers, set-top boxes, MP4PLAYER and other playback devices are all equipped with H265 hardware decoding function, manufacturers need to pay hundreds of millions of yuan of patent fees to HEVC advance department every year, and no one wants to buy this account. At present, only computer CPU can do soft solution, and mobile phone CPU can directly card. If the device does not support playback, no matter how good the technology is, it is useless.
