That controls whether or not the (optional) FFMpeg-based backend is built. The only special CMake variable is the boolean This library using the standard CMake process. To the directory where you have unzipped the SDK. To utilize a custom SDK, set the NVIDIA_VIDEO_CODEC_SDK CMake option These headers enable additional features that can improve the quality of the This library can optionally make use of the NVIDIA Video Codec SDK headers Information would be lost in the scenario above. Note that the underlying H.264 stream does not support alpha channels. Pipe_destroy(dec) // destroy the decoder when finished Use_frame(rgb, width, height) // blit, save whatever. Nvpipe_decode(dec, strm,N, rgb, width, height, NVPIPE_RGB) Recv(socket, strm, from_network_byte_order(N). Osize on the encode side will become N in the sample decode scenario: pipe* dec = nvpipe_create_decoder(NVPIPE_H264_NV) ) īe sure to destroy the encoder when done. Uint32_t size = to_network_byte_order_zu(osize) Send the frame size and compressed stream to the consuming side. Nvpipe_encode(enc, rgba, width*height*4, output,&osize, width, height, Pipe* enc = nvpipe_create_encoder(NVPIPE_H264_NV, bitrate) Nst uint64_t bitrate = width*height * fps*f_m*0.07
Id* output = malloc(max_osize) // place for the compressed stream. Network communication aspects, allowing your application to dictate theĪ sample encoding scenario: nst size_t width=., height=. The library is specifically designed to be easily integratable into existing If you're looking for ultimate encode/decode performance, you may want to consider using NvCodec directly.
Please note that NvPipe acts as a lightweight synchronous convenience layer around the NVIDIA Video Codec SDK and doesn't offer all high-performance capabilities. Networked interactive client/server application. It is a great choice to drastically lower the bandwidth required for your Provides access to NVIDIA's hardware-accelerated codecs as well as a fallback NvPipe is a simple and lightweight library for low-latency video compression.
