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. FFmpeg should be used for evaluation or quick integration, but it may not provide control over every encoder parameter. NVDECODE and NVENCODE APIs should be used for low-level granular control over various encode/decode parameters and if you want to directly tap into the hardware decoder/encoder. This access is available through the Video Codec SDK.
A: After you download the SDK, please refer to the "ReadMe.txt" which lists the minimum required display driver version. You need to install the right drivers or else the SDK will fail to start and this is the first thing you should check in case there is an initialization failure.
A: We strongly recommend all application developers to go through the programming guides in detail before writing any application. In particular, for some hints on this question, please go through the following sections in the documentation. These sections provide valuable tips for optimizing latency/memory utilization and choosing the right settings for different use-cases.
A: Video encoding latency consists of two components: (a) Latency due to encoding algorithm (e.g. B-frames, look-ahead, VBV buffering), and (b) Latency due to the processing required to encode the bits using hardware or software. For a typical end-to-end streaming scenario to incur low latency, it is important to lower both components as much as possible. Typically, latency in (a) can be minimized by choosing infinite GOP with IPPPP... structure, no look-ahead and lowest possible VBV buffer for the given bitrate and available channel bandwidth, without giving away too much of encoding quality. Each of these can all be set via NVENCODE API. In Video SDK 10.0 and above, setting the tuning info to low-latency or ultra-low-latency will set most of these parameters automatically. Latency contributed by (b) can be minimized by choosing the correct preset, and rate control mode with correct number of rate control passes. Naturally, 2-pass requires more time to encode than 1-pass rate control mode. Running quarter-resolution first pass requires less time than running both passes at full resolution.
In addition to the above, the overall encoding latency is also affected by efficient application design (or lack thereof). Since NVENC can run in parallel to CUDA and graphics workload, it is important to ensure that the NVENC pipeline is kept fed with data and the context switches between NVENC pre-processing (which uses small amount of CUDA bandwidth) and other graphics/CUDA workload are minimized. The specifics of this depend on the workload, but should be analyzed using a tool such as GPUView (available as a part of Windows Performance Toolkit).
A: First of all, it is important to note that the aggregate video encoding performance of GPUs is not solely defined by the raw number of NVENCs on the GPU silicon. As anyone familiar with video encoding will know, talking about video encoding performance without any reference to encoding quality is meaningless. For example, one can encode a video at blazing fast speed, without any regard to quality and claim extremely high performance, doubling the performance on GPUs with multiple NVENC engines. But such usage may not be of much use in practical situations. Therefore, it is important to think of encoding performance at a specific quality. NVIDIA encoding benchmarks use the bitrate savings compared with open source encoders x264 and x265's medium preset output, as a measure of the encoding quality. The performance vs. quality spectrum thus obtained is published for various generations of GPUs on Video Codec SDK web site. Most of the commonly used presets on Pascal have an equivalent preset in Turing with similar quality and 2x performance, thereby making it possible to get the same performance from both GPU generations, despite Turing GPUs having only 1 NVENC engine. This requires the application to choose appropriate encoding settings, depending upon the GPU in use. For low-latency presets and tuning, Turing NVENC provides equivalent settings to achieve higher performance per NVENC than Pascal NVENC for latency tolerant encoding. For latency-sensitive (low-latency) encoding, Turing NVENC does not provide 2x performance, but that's not needed because most of the low-latency scenarios are bottlenecked by the graphics/CUDA utilization and not NVENC utilization.
In short, despite the reduction of number of NVENCs from Pascal to Turing, one should be able to achieve equivalent encoding performance per GPU, in most practical use cases by adjusting the encoding settings to normalize the encoding quality.
A: NVENCODE API expose APIs which allow users to query the maximum API versions supported by the underlying driver. Depending on the maximum API version supported by driver, the application can launch code at runtime compiled with the appropriate API.
A: For decoder, please refer to the NVDEC application note included in the SDK documentation to get an idea about performance. For encoder, the answer depends on many factors, some of which include: GPU in use and its clock speed, settings used for encoding (i.e. encode quality), memory bandwidth available, application design. It is especially important to note that GPU encoding performance is always tied to the encoding quality, and the performance can vary greatly depending upon the chosen settings. For example, B-frames, 2-pass rate control mode, or look-ahead will improve the encoding quality at the cost of performance. Encoding presets also influence quality vs performance trade-off significantly. Please refer to the table containing indicative performance figures for the video encoder in NVENC application note included in the SDK package.
A: Create separate Cuda streams for encode and decode. For NVDECODEAPI and NVENCODEAPI you can specify the stream where you want to Cuda kernels using CUVIDPROCPARAMS::output_stream and NvEncSetIOCudaStreams(..) respectively.
Suma: para descargar el cdec HEVC gratuito, el enlace ms-windows-store://pdp/?ProductId=9n4wgh0z6vhq ya no funciona. Afortunadamente, an puede obtener las extensiones de video HEVC gratis de otros sitios, descargar cdecs HEVC gratuitos y usar alternativas de cdecs HEVC.
HEVC (o H.265) se gan su reputacin a partir de septiembre de 2014 cuando la Asociacin de Discos Blu-ray y Apple anunciaron la compatibilidad del HEVC en sus productos. A partir de ese momento, el cdec de video se aplica a una amplia gama de campos, incl. GoPro, iPhone, cmaras modernas, videos de alta resolucin 4K/8K, transmisin en lnea, Blu-rays 4K, etc. Sin embargo, Microsoft no brinda soporte nativo para el cdec HEVC en Windows 11/10.
En este artculo, nos centraremos en cmo descargar extensiones de cdec HEVC gratis para reproduccin de video 4K/8K, cmo reproducir videos HEVC sin instalar paquetes de cdec HEVC/H.265 adicionales, explicar qu es el cdec HEVC, junto con errores y preguntas frecuentes sobre Reproduccin HEVC que ms preocupa a los usuarios.

Resumen: Puedes abrir "ms-windows-store://pdp/?ProductId=9n4wgh0z6vhq" para descargar las extensiones de video HEVC gratuitas del fabricante del dispositivo. Pero si esto no funciona, siempre puedes comprar y descargar las extensiones oficiales HEVC desde la Tienda de Microsoft. Mientras tanto, existen varios paquetes gratuitos de cdecs HEVC y VLC para ayudar a abrir videos HEVC H.265.
Los paquetes de cdecs facilitan la reproduccin de videos al instalar varios cdecs a la vez. Sin embargo, es probable que generen conflictos de software y estn llenos de adware o spyware. Por eso, Windows 10 introduce oficialmente las extensiones de cdec HEVC. Microsoft cobra $0.99 por su cdec HEVC oficial. Antes de descargar gratis las extensiones de video HEVC y realizar una compra, debes saber que:
Por cierto, Microsoft instala automticamente actualizaciones de seguridad para estos cdecs con el fin de garantizar la seguridad. Asegrate de habilitar "Actualizar aplicaciones automticamente" en "Configuracin". Sin embargo, algunos usuarios desafortunados estn encontrando errores con las Extensiones de Video HEVC de Microsoft en Windows 10. Por ejemplo, hay errores como la extensin HEVC no se inicia, no se puede descargar/instalar las extensiones HEVC despus de la compra, no se pueden abrir videos MKV con cdec HEVC, etc.
Exista un paquete llamado "Extensiones de video HEVC del fabricante del dispositivo" que se poda descargar de forma gratuita en Windows 10 desde la Tienda de Microsoft. El cdec HEVC gratuito es exactamente el mismo que las "Extensiones de video HEVC" oficiales de $0.99 de Microsoft, pero es gratuito. Sin embargo, no puedes obtener la versin gratuita de las "Extensiones de video HEVC del fabricante del dispositivo" a travs del enlace ms-windows-store://pdp/?ProductId=9n4wgh0z6vhq u otros enlaces.
