rocDecode samples
********************************************************************

rocDecode samples are available in the `rocDecode GitHub repository <https://github.com/ROCm/rocm-systems/tree/develop/projects/rocdecode/samples>`_.

The ``ROCM_PATH`` environment variable must point to the location of your ROCm installation to use the samples.

FFmpeg development libraries must be installed to build and run samples that use FFmpeg for either demultiplexing or decoding:

.. code:: 

  sudo apt install libavcodec-dev libavformat-dev libavutil-dev

You can find a walkthrough of the ``videodecode.cpp`` sample at :doc:`Understanding the videodecode.cpp sample <../how-to/using-rocDecode-videodecode-sample>`.
