Ffmpeg vcodec h2642/22/2024 ![]() ![]() For example, in a game recording and streaming scenario like streaming to using Open Broadcaster Software (OBS), encoding being completely offloaded to NVENC makes the graphics engine bandwidth fully available for game rendering. With complete encoding (which is computationally complex) offloaded to NVENC, the graphics engine and the CPU are free for other operations. On Ada, multiple NVENC coupled with AV1 enables encoding 8k video at 60fps alongside a higher number of concurrent sessions. AV1 is the state of the art video coding format that supports higher quality with better performance compared to H.264 and HEVC. Introducing AV1 encoding with Video Codec SDK 12.0 on NVIDIA’s Ada architecture. ![]() #查看缺失依赖位置 find /usr -name 'libavdevice.so.58' #export出来 export LD_LIBRARY_PATH =/usr/local/lib/įfmpeg -re -rtsp_transport tcp -i “rtsp:///vod/mp4:BigBuckBunny_115k.NVENC - Hardware-Accelerated Video Encoding 如果出现 ffmpeg: error while loading shared libraries: libavdevice.so.: cannot open shared object file: No such file or directory异常 #进入ffmpeg目录 cd ffmpeg #新增 export PATH = $PATH:/usr/local/ffmpeg/bin ![]() #安装 make & make install #新增 vim /etc/ld.so.conf, configure -prefix =/usr/local/ffmpeg -enable-gpl -enable-libx264 #新增 export PATH = $PATH:/usr/local/x264/binĮxport PKG_CONFIG_PATH =/usr/local/x264/lib/pkgconfig configure -prefix =/usr/local/x264 -enable-shared -enable-static -enable-debug Make sudo make install #复制同步 sudo ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/Īdd_header 'Access-Control-Allow-Credentials' 'true' #add additional HTTP headerĪdd_header 'Access-Control-Allow-Origin' '*' #add additional HTTP headerĪdd_header Access-Control-Allow-Headers X-Requested-With Īdd_header Access-Control-Allow-Methods GET,POST,OPTIONS Īdd_header 'Cache-Control' 'no-cache' } configure -prefix =/usr/local/nginx -add-module =. ![]() Yum install -y openssl* ncurses-devel pcre-devel ![]()
