Why is h265 not popular?

The reasons why h265 is not popular: 1. h265 real-time encoding is difficult, and the complexity of h265 encoding increases geometrically compared with H264; 2. The h265 encoder is difficult to use; 3. h265 decoding is difficult, and the h265 algorithm is complex Compared with H264, the speed is improved by 2 to 10 times.

Why is h265 not popular?

Reasons for not being popular:

• h265 real-time encoding is difficult

##In After video collection, it is necessary to reduce the amount of video data while ensuring visual effects. Coding and compression are particularly important during data transmission and storage. The complexity of H.265 encoding increases exponentially compared to H.264, and the encoding time also increases. It is difficult to achieve real-time encoding with existing terminal equipment, so it is difficult for live broadcast platforms to use H.265 encoding to play videos at this stage.

• h265 encoder is difficult to use

H.265 only stipulates a range of available technologies. Many features can be used when encoding, and Its not mandatory. Therefore, the difficulty of using the H.265 encoder is about 2-3 times that of h.264.

• h265 decoding is difficult

H.265 brings a compression efficiency that is much higher than H.264, and also brings a higher The decoding difficulty of H.264 is several times higher, the algorithm complexity is 2-10 times higher than that of H.264, and the amount of calculations soars to 400-500GOPS. Complex calculations pose severe challenges to the processor.
