WebMay 4, 2024 · Hi I have a NVIDIA Jetson AGX Xavier and I need to perform hardware encoding for some h264 video streams. My solution is based on FFMPEG with h264_nvenc encoder. I read from this post that hardware encoding is currently not supported by Jetson AGX Xavier. My first question is if it’s possible to have a timeline indicating when the … WebEnabling GPU video decoder/encoder. TorchAudio can make use of hardware-based video decoding and encoding supported by underlying FFmpeg libraries that are linked at runtime. Using NVIDIA’s GPU decoder and encoder, it is also possible to pass around CUDA Tensor directly, that is decode video into CUDA tensor or encode video from CUDA tensor ...
