ios - difference between Hybrid and Hardware decoding -

Hybrid and hardware decoding settings exist for the iOS player (such as an app player or opener). Both are designed for the H.264 codec (usually to play HD files with H.264 codecs). I do not understand the difference between them.

Can anyone explain me?

When a decoder is labeled as a hardware decoder, So that means decoding is done entirely by the hardware block in the forum. When such a Fixed Function Hardware Block exists, one of the main factors is believed that the functionality will be limited, only those features supported by the hardware decoder will be supported and In case, a new feature is required, you have to go for the same redesign and re-spin .

The main advantage of the hardware decoder is that it is usually power efficient because the hardware is specially designed to implement functionality. Additionally, overall system performance is also optimized to match the output formats of the hardware decoder block to GPU

When a decoder is set to software Is labeled as decoder, it is a pure software based implementation of the codec running on the CPU. This implementation functionality helps in increasing the functionality of the built-in codec because it is just a replacement for the older version of the SW version.

The main disadvantage of a software decoder is that this power will be intensified, with large memory access for large video resolutions, the need for power for software decoder is greatly increased and the battery is rapidly drained It is certainly not a good option for long offers of big offers and playback.

Hybrid decoders is another class that integrates a software module that acts as a pre-processor usually with a built-in hardware engine For example, if there is an underlying high performance DSP or SIMD engine, then the serial part of decoding such as pre-processor CIVLD and other header / bit parsing can operate, Intra Prediction , Motion compensation will be a more complex mathematical part of the operation by an underlying hardware segment

some hybrid decoders Regarded as the hardware decoders Expertise, but they renewed Hardware Decoders are available today worldwide.
