Update PyTorch and TorchAudio with nightly builds ¶ | GPU GI CI PID Type Process name GPU Memory | | Fan Temp Perf Pwr:Usage/Cap| Memory-Usage | GPU-Util Compute M. | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. † For details on NVDEC/NVENC and FFmpeg, please refer to the following articles. 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.
