+GPU Decoder
+===========
+
+GPU decoder depends on ffmpeg for demuxing, uses NVDECODE APIs from the nvidia-video-codec sdk and uses cuda for processing on gpu. In order to use this, please follow the following steps:
+
+* Download the latest `nvidia-video-codec-sdk <https://developer.nvidia.com/nvidia-video-codec-sdk/download>`_
+* Extract the zipped file.
+* Set TORCHVISION_INCLUDE environment variable to the location of the video codec headers(`nvcuvid.h` and `cuviddec.h`), which would be under `Interface` directory.
+* Set TORCHVISION_LIBRARY environment variable to the location of the video codec library(`libnvcuvid.so`), which would be under `Lib/linux/stubs/x86_64` directory.
+* Install the latest ffmpeg from `conda-forge` channel.
+
+.. code:: bash
+
+    conda install -c conda-forge ffmpeg
+
+* Set CUDA_HOME environment variable to the cuda root directory.
+* Build torchvision from source:
+
+.. code:: bash
+
+    python setup.py install
