Nvidia Video Encoder Api
There are no way to notice why video encoder session initialization is failed.
Nvidia video encoder api. We can not find the api to get concurrent session limit on nvidia codec sdk. Defines a helper class for v4l2 video encoder. The nvenc hardware takes yuv rgb as input and generates an h 264 hevc compliant video bit stream. Discussion in this link is almost same this issue.
It s a system and hidden file. This file is part of nvidia video encoder api. Nvdecode and nvencode apis should be used for. It can relieve the burden of cpu so as to make the pc perform fully accelerated video encoding using the gpu of the nvidia graphics card.
Gpu hardware accelerator engines for video decoding referred to as nvdec and video encoding. Nvencodeapi dll is usually located in the system sub folder and its usual size is 348 992 bytes. Refer to v4l2 video encoder for more information on the encoder. The nvencodeapi dll is a nvidia video encoder api version 1 0 0.
The video encoder device node is dev nvhost msenc the category name for the encoder is nvenc. Nvidia video codec sdk encoder vnvencodeapi pg 06155 001 v11 1 chapter 1. Dda interop sample application demonstrate usage of windows desktop duplcation api. With decoding encoding offloaded the graphics engine and the cpu are free for other operations.
Nvencodeapi dll is developed by nvidia corporation. I the client should call nvencgetencodeprofileguidcount to get the number of supported encoder guids from the nvidia video encoder interface. Samples demonstrating how to use various apis of nvidia video codec sdk nvidia video. 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.
Sample applications that demonstrate usage of nvidia video sdk apis for gpu accelerated video encoding decoding. Ffmpeg should be used for evaluation or quick integration but it may not provide control over every encoder parameter. Definition at line 59 of file nvvideoencoder h. Do we have the way to get workaround this issue.
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. Samples demonstrating how to use various apis of.
