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.

The client application should also query the capabilities using the respective capability APIs before enabling any feature. 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. A: Video encoding latency consists of two components: a Latency due to encoding algorithm e. B-frames, look-ahead, VBV buffering , and b Latency due to the processing required to encode the bits using hardware or software.

This determines the rate at which frames are going to be encoded. Bitrate : Enter the bitrate appropriate for your Upload Speed, as we discussed in the previous section. Keep in mind that some platforms have a maximum bitrate i. Keyframe Interval : Set to 2. Streaming platforms may limit what you can select here, and most require a setting of 2.

Preset : Select Quality. You can change this to Max Quality to enable 2-pass encoding; this will provide you a minor quality increase but may cause problems in limited situations in maxed out GPUs.

Profile : Set to High. Profile determines a group of settings in the H. Look-ahead : Checked. This allows the encoder to dynamically select the number of B-Frames, between 0 and the number of B-Frames you specify. B-frames are great because they increase image quality, but they consume a lot of your available bitrate, so they reduce quality on high motion content.

Look-ahead enables the best of both worlds. Psycho Visual Tuning : Checked. This enables the Rate Distortion Optimization in the encoder, which greatly optimizes the way you use bitrate, improving image quality on movement.

GPU : 0. If you have 2 GPUs in your system, you can select which one is used to encode. This is not recommended, as NVENC is already very efficient and the little gain you can get from using a second card is lost by having to copy the frame to the second GPU. Max B-Frames : Set to 4. If you uncheck the Look-ahead option, reduce this to 2 B-Frames. Recording Settings.
