Nvidia Encoder Api
This is a coarse level of control exposed by the nvidia encoder interface to the client.
Nvidia encoder api. Refer to v4l2 video encoder for more information on the encoder. We can not find the api to get concurrent session limit on nvidia codec sdk. The nvidia encoder interface exposes various presets to cater to different use cases which can be used by the client. The nvidia encoder supports use of the following types of devices.
Defines a helper class for v4l2 video encoder. Nvenc is nvidia s encoder. Ffmpeg should be used for evaluation or quick integration but it may not provide control over every encoder parameter. Nvidia video codec sdk get started if you are looking to make use of the dedicated decoding encoding hardware on your gpu in an existing application you can leverage the integration already available in ffmpeg.
Nvdecode and nvencode apis should be used for. Detail overview of nvenc encoder api swagat mohapatra senior lead engineer gpu multimedia sw agenda introduction to nvenc sdk detailed overview of nvenc api advanced topics rate control modes low latency encoding benefits of hw based encoder low power low latency high performance ease of programming nvenc video encoding solutions fixed function hardware nvenc entire encode pipeline. Gpu hardware accelerator engines for video decoding referred to as nvdec and video encoding. Nvencode api is a c api and uses a design pattern like c interfaces wherein the application creates an instance of the api and retrieves a function pointer table to further interact with the encoder.
This means that your gpu can operate normally regardless of whether you use this region to stream or record. Definition at line 59 of file nvvideoencoder h. It s a physical section of our gpus that is dedicated to encoding only. 2 4 encoder preset configurations the nvidia encoder interface exposes various presets to cater to different use cases which can be used by the client.
Other encoders such as x264 use your cpu to encode which takes resources away from other programs such as your game. Using presets through the encoder interface will automatically set all of the relevant encoding parameters. Nvidia gpus contain one or more hardware based decoder and encoder s separate from the cuda cores which provides fully accelerated hardware based video decoding and encoding for several popular codecs. Using presets through the encoder interface will automatically set all of the relevant encoding parameters.
With decoding encoding offloaded the graphics engine and the cpu are free for other operations. Do we have the way to get workaround this issue. The video encoder device node is dev nvhost msenc the category name for the encoder is nvenc.
