Next we download the source code of FFmpeg 4.

State without impacting any branches by performing another checkout. You can look around, make experimentalĬhanges and commit them, and you can discard any commits you make in this Remote: Total 819 (delta 439), reused 0 (delta 0) To build FFmpeg with NVDEC/NVENC, we first install the headers that FFmpeg uses to interact with Video Codec SDK.

In the following sections, we build FFmpeg 4 libraries with NVDEC/NVENC support, then we demonstrate the performance imrovement using TorchAudio’s StreamReader/ StreamWriter. TorchAudio’s official binary distributions are compiled with FFmpeg 4 libraries, and they contain the logic required for hardware-based decoding/encoding. NVIDIA GPU with hardware video decoder/encoder.įFmpeg libraries compiled with NVDEC/NVENC support. To use NVENC/NVDEC with TorchAudio, the following items are required. Please check out this tutorial in Google Colab. This tutorial was authored in Google Colab, and is tailored to Google Colab’s specifications.
