Nvidia Encoder Ffmpeg
Ffmpeg is one of the most popular open source multimedia manipulation tools with a library of plugins that can be applied to various parts of the audio and video processing pipelines and have achieved wide adoption across the world.
Nvidia encoder ffmpeg. The latter has more options to configure but both will give you comparable quality to x264 medium as long as you have a turing gpu encoder. The video hardware accelerators in nvidia gpus can be effectively used with ffmpeg to significantly speed up the video decoding encoding and end to end transcoding at very high performance. Ffmpeg vsync 0 hwaccel cuvid hwaccel device 1 c v h264 cuvid i input mp4 c a copy c v h264 nvenc b v 5m output mp4 optimizations. The hardware encoder and hardware decoder are referred to as nvenc.
Video encoding decoding and transcoding are some of the. I want to use ffmpeg to accelerate video encode and decode with an nvidia gpu. All encoder and decoder units should be utilized as much as possible for best throughput. Introduction all nvidia gpus starting with kepler generation support fully accelerated hardware video encoding and decoding.
Ffmpeg is an extremely versatile video manipulation utility and used by many related software packages. This article documents some of the ffmpeg command line switches require to perform hardware video encoding on both nvidia and amd gpus. Encode avi to h 264 video software encoding ffmpeg i input avi c v libx264 output mp4 encode avi to h 265 video software encoding ffmpeg i input avi c v libx265 output mp4. After the work spearheaded by rostislav pehlivanov and claudio freire the now stable ffmpeg native aac encoder is ready to compete with much more mature encoders.
With modern obs studio you have two options. Using ffmpeg with nvidia gpu hardware acceleration vda 08430 001 v02 1 chapter 1. Nvidia smi can be used to generate real time information about nvenc nvdec and general gpu utilization. The fraunhofer fdk aac codec library for android was added in 2012 as the fourth supported external aac encoder and the one with the best quality and the most features supported including he aac and he aacv2.
