This is known as streaming latency.ДЇor one-way transmissions, some latency is no big deal. For example, some protocols can instantly transfer data from the hardware encoder to the destination, whereas others take more time. In addition, some streaming protocols will only work with particular codecs, whereas other protocols are codec-agostic.Дifferent video streaming protocols can deliver video online with varying degrees of delay. Different hardware encoders support specific sets of streaming protocols.

ItвЂ™s a set of rules that decides how to cut up the encoded video into smaller chunks and deliver it to the destination, on time and in the correct order. Streaming protocols: What they are and how they workДЄ streaming protocol is a method by which multimedia is delivered to the streaming destination. No matter how high the bitrate or how powerful the hardware encoder, low bandwidth can become the bottleneck for streaming quality.ДЄbove is a screenshot of the encoding settings tab in Pearl Web UI In addition to adequately chosen bitrate, another crucial factor for high-quality online video delivery is sufficient local upload bandwidth.

For example, the video bitrate range for a 1080p at 30 fps stream is between 3,000вЂ“6,000 Kbps, whereas the bitrate range for 4K 60 fps streaming is between 20,000вЂ“51,000 Kbps. The bitrate setting will depend on the chosen codec, resolution, and frame rate. On the other hand, setting the bitrate too high may cause video buffering for viewers because the file size becomes too large. A low bitrate setting will cause the live stream to look jittery and low quality. The higher the bitrate, the higher the video quality вЂ“ but also the larger the file size.ДЇinding the right bitrate setting is about balance. Bitrate is commonly measured in kilobits per second (Kbps) and less frequently in megabits per second (Mbps). BitrateД«itrate describes how much data is transmitted per unit of time. Standard frame rates include 24, 25, 30, and 60 fps, with 30 fps being the most widely used setting for online streaming. Frame rateДЇrame rate is the number of images encoded per second, in frames per second (fps). Simply send the highest quality stream and the CDN will present the viewer with a range of resolutions. If the CDN youвЂ™re using includes transcoding (many do), thereвЂ™s no extra work to be done on your end. Higher streaming resolutions such as 4K are less popular because they require significant processing power, upload bandwidth, and 4K resolution support on the viewerвЂ™s side.Д«ecause everyoneвЂ™s setup is a little different, itвЂ™s good practice to give viewers a choice of resolutions when viewing your content. Encoding resolutionД®ncoding resolution is the video frame size, expressed in pixels as width x height.

The most commonly used audio codec is called AAC. Note that audio gets encoded separately from the video. It promises identical quality to H.264 at about half the bitrate, decreasing upload bandwidth requirements. H.265/HEVC is the next generation of codecs after H.264/AVC. H.264/AVC is arguably the most commonly used codec today. Not all video codecs are fit for live streaming.ДЄ few examples of widely used video codecs for streaming are Motion-JPEG (MJPEG), H.264/AVC, and H.265/HEVC. Different codecs provide different types of compression to fit specific use cases. CodecsДЄ codec is the compression method for making media files smaller.

Here is an overview of the key encoding parameters users have control over. Streaming platforms often offer a list of recommended encoding settings for live streaming. Generally speaking, the higher the settings (within specific value ranges),the higher the video quality. Encoding settings: Key terms to understandД®ncoding settings have a direct impact on stream quality.
