Hello. I want to do HW encoding/decoding in jetson. I am using jetpack 4.6. I have finished the ffmpeg implementation in one step and this is the result. $ ffmpeg -codecs | grep 264 ffmpeg version git-2022-08-09-d931554 Copyright (c) 2000-2022 the FFmpeg developers built with gcc 7 (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) configuration: --enable-cuda-nvcc --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --enable-gpl --enable-shared --enable-libx264 libavutil 57. 32.101 / 57. 32.101 libavcodec 59. 42.101 / 59. 42.101 libavformat 59. 30.100 / 59. 30.100 libavdevice 59. 8.101 / 59. 8.101 libavfilter 8. 46.101 / 8. 46.101 libswscale 6. 8.102 / 6. 8.102 libswresample 4. 8.100 / 4. 8.100 libpostproc 56. 7.100 / 56. 7.100 DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders: h264 h264_v4l2m2m h264_cuvid ) (encoders: libx264 libx264rgb h264_nvenc h264_v4l2m2m ) ffmpeg -hwaccels ffmpeg version git-2022-08-09-d931554 Copyright (c) 2000-2022 the FFmpeg developers built with gcc 7 (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) configuration: --enable-cuda-nvcc --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --enable-gpl --enable-shared --enable-libx264 libavutil 57. 32.101 / 57. 32.101 libavcodec 59. 42.101 / 59. 42.101 libavformat 59. 30.100 / 59. 30.100 libavdevice 59. 8.101 / 59. 8.101 libavfilter 8. 46.101 / 8. 46.101 libswscale 6. 8.102 / 6. 8.102 libswresample 4. 8.100 / 4. 8.100 libpostproc 56. 7.100 / 56. 7.100 Hardware acceleration methods: cuda However, when I try to use the hardware decoder with the ffmpeg command, I get an error. nakayo@nakayo-desktop:~$ ffmpeg -y -vsync 0 -c:v h264_cuvid -i rtsp://192.168.2.191:8554/camera camera.mp4 ffmpeg version git-2022-08-09-d931554 Copyright (c) 2000-2022 the FFmpeg developers built with gcc 7 (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) configuration: --enable-cuda-nvcc --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --enable-gpl --enable-shared --enable-libx264 libavutil 57. 32.101 / 57. 32.101 libavcodec 59. 42.101 / 59. 42.101 libavformat 59. 30.100 / 59. 30.100 libavdevice 59. 8.101 / 59. 8.101 libavfilter 8. 46.101 / 8. 46.101 libswscale 6. 8.102 / 6. 8.102 libswresample 4. 8.100 / 4. 8.100 libpostproc 56. 7.100 / 56. 7.100 -vsync is deprecated.

Is there a mistake in the build method? Thank you.
