您好！我们公司现在在使用NVIDIA Jetson Xavier NX，现在我们想在NVIDIA Jetson Xavier NX 上利用ffmpeg4.2支持NVIDIA硬件加速来实现编解码功能, 以便减少视频播放延时大的问题。我们查了NVIDIA的官网，根据官网介绍( Accelerated Decode with ffmpeg — Jetson Linux<br/>Developer Guide 34.1 documentation ): Accelerated Decode with ffmpeg Decode Functional Flow This section d…

Hi, Please refer to explanation in Question in NVDEC Accelerated Decode with ffmpeg - #3 by DaneLLL

您好！我按照您提供的Jetson TX2 and FFmpeg - Can’t initialize nvrm channel - #5 by DaneLLL 已经成功的编译好ffmpeg-4.2.7，make && make install 并且可以正常运行ffmpeg命令。我运行 ./ffmpeg -decoders命令时，打印信息如下： root@nvidia-desktop:/home/nvidia/working-fu/ffmpeg-4.2.7-nvidia# ./ffmpeg -decoders | grep nvv4l2 ffmpeg version 4.2.…

Hi, Hardware decoding should be enabled. You may run this command: ffmpeg-4.2.2$ ./ffmpeg -c:v h264_nvv4l2dec -i /opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.mp4 a.yuv And execute sudo tegrastats to check if NVDEC is up and running.

您好！我成功编译ffmpeg-4.2.7后，是可以正常运行fffmpeg命令来实现解码的。 fffmpeg命令实现解码运行后的打印信息如下： ffmpeg-4.2.7-nvidia# ./ffmpeg -c:v h264_nvv4l2dec -i /home/working-video/video-decenc-test/test_cut.h264 -r 30 -y /home/working-video/video-decenc-test/video-dec%03d.jpg ffmpeg version 4.2.7 Copyright (c) 2000-2022 the FFmpe…

您好！我编译好ffmpeg-4.2.7后，是可以正常运行./ffmpeg -c:v h264_nvv4l2dec -i /opt/nvidia/deepstream/deepstream-5.0/samples/streams/sample_720p.mp4 a.yuv命令来解码的。但是我修改./configure，在原来基础./configure --enable-nvv4l2dec --enable-libv4l2 --extra-libs=“-L/usr/lib/aarch64-linux-gnu/tegra -lnvbuf_utils” --extra-cflags=“-I /…

您好！我下载、编译、安装好了NVIDIA的ffmpeg，然后运行基于 NVDEC的硬件加速解码的ffmpeg命令，输出信息如下： ffmpeg-4.2.7-nvidia/bin# ./ffmpeg -c:v h264_nvv4l2dec -i /home/working-video/700818_023723.h264 -r 30 -y /home/working-video/video-harddec-test/video-dec%03d.jpg ffmpeg version 4.2.7 Copyright (c) 2000-2022 the FFmpeg developers b…

Hi,
Video Codec SDK is not supported on Jetson platforms. We have a package to enable hardware decoding with jetson_multimedia_api. Please check
