The rocDecode core APIs
|
||
|
|
********************************************************************
|

|
|
|
||
|
|
The rocDecode core APIs are intended for users who want to have full control of the decoding pipeline and interact with the core components instead of the utility classes. The :doc:`Using the rocDecode videodecode sample <../how-to/using-rocDecode-videodecode-sample>` provides an introduction to using the utility classes.
|
||
|
|
|
||
|
|
The rocDecode core APIs are exposed in header files in the |apifolder|_ folder of the `rocDecode GitHub repository <https://github.com/ROCm/rocDecode>`_.
|
||
|
|
|
||
|
|
:doc:`The rocDecode parser API <./rocDecode-parser>` is exposed in |rocparser|_. It contains functions that create and destroy the parser, as well as functions that parse the bitstream.
|
||
|
|
|
||
|
|
:doc:`The hardware decoder API <./rocDecode-hw-decoder>` is exposed in |rocdecode|_. It contains functions that create, control, and destroy the decoder, as well as functions that decode the parsed frames on the GPU.
|
||
|
|
|
||
|
|
:doc:`The software decoder API <./rocDecode-sw-decoder>` is exposed in |rocdecodehost|_. It contains the same functionality as ``rocdecode.h``, but all the operations are run on the host rather than the GPU.
|
||
|
|
|
||
|
|
:doc:`The bitstream reader API <../how-to/using-rocDecode-bitstream>` is exposed in |bitstreamreader|_. It provides an alternative to the FFMpeg demuxer and contains a simple stream file parser that can read elementary files and IVF container files.
