How To Stop Buffering Problems When Live Streaming

How To Stop Buffering Problems When Live Streaming

How To Stop Buffering Problems When Live Streaming

Live streaming has a charm to it. People stick to watching it for long without batting their eyelids. But, just when you start getting into sync with the live stream does that dreaded thing starts to happen! Buffering. The small rounded dots seems to go on forever.

“Why does my video keep buffering?”

At least one-half of viewers who watched a live stream swear to ask this question helplessly.

There are 5 common reasons that cause buffering issues:

  • 1. The connection between the live video encoder and the server is interrupted
  • 2. The Internet connection speed is inadequate to accommodate the encoder’s bitrate
  • 3. Extinguishing the bitrate available for the live streaming platform
  • 4. Excess load on the server making it to crash
  • 5. The Internet bandwidth may be inadequate to push the live stream completely

Is it possible to spot what causes buffering issues in live streaming and seal them once and for all?

In most cases, YES. Here is how to fix it.

  • Adaptive Bit-rate Streaming
  • Keep the Bandwidth Under 1 Mbps
  • Maintain a Higher Upload Speed
  • Set a Lower Keyframe Interval
  • Don’t Overload Your Encoder
  • Pick Wired Encoder Above a Wireless One

1. Adaptive Bit-Rate Streaming

Quite often, in live streaming, as well as on the Internet, it is not easy for data to reach the server. Due to network issues or system issues, the data might not cross to the server completely, as a result of which buffering problems kick into the live stream.

But, there is a quick fix. Adaptive bit-rate streaming helps combat these issues by streaming the video in lower quality than totally disconnecting the stream. Adaptive bit-rate streaming ensures that the live stream is not interrupted and continues with a bit rate that adapts to the available bandwidth.

2. Keep The Bandwidth Under 1 Mbps

YouTube reports that mobile video consumption doubles every year. Mobile has replaced TV and desktops as the main device for media consumption. So, there is a compulsion to make your live stream compatible with mobile devices.

A good practice to achieve mobile-friendly or any screen-friendly live streaming is to keep the bandwidth under 1 Mbps. If your bandwidth exceeds 1 Mbps, there is a high chance that the live stream will experience buffering issues. Most encoders come with the flexibility to set the bandwidth at which your video stream must happen. As a golden rule, fix it under 1 Mbps and your live stream must work fine and smooth.

3. Maintain A Higher Upload Speed

Your upload speed and live streaming buffering are directly connected. It is ideal to have twice the upload speed compared to the bitrate. When the upload speed falls, the stream gets delayed in reaching the user or gets distributed in broken packets which are shown as buffering.

To avoid that maintain a higher upload speed, which means you will require a higher Internet bandwidth. Other factors like a wired encoder will also contribute to the live stream upload speed.

4. Set A Lower Keyframe Interval

Setting an optimum keyframe interval can help mitigate the issues in video buffering. However, there is a catch. You cannot set two keyframes two farther from each other, nor can you set them too close.

If set apart in longer intervals, the video stream may not be capable of responding when there is a network hitch. If kept too close, the quality of the live stream will deplete. A keyframe interval of 2 to 3 seconds between each other works fine in most cases.

5. Don’t Overload Your Encoder

An encoder is a bridge that forges a connection between your camera and the user’s screen. The encoder is what transmits the video as it is from the camera across the Internet to the user screen. That said, it is obvious that your encoder will have to handle serious traffic regularly.

If you pile it with additional heavy-duty tasks like recording the live stream simultaneously, there is a huge risk that the encoder will snap from functioning. This will inevitably cause live streaming issues. However, this should not happen if you pick a conducive encoder that can handle heavy-duty live streaming as well as its recording easily.

6. Pick Wired Encoder Above a Wireless One

Wireless encoders are good and help reduce the clutter in a physical recording environment. But, they have some inherent cons. Wi-fi-connected encoders might get their signals messed with neighboring signals. Also, if there are plenty of users logging into the same wifi network, the live stream has a fatty chance of being disrupted.

Using a cloud video encoder is the only option you have, go for dedicated wifi with a good throw area for a buffer-free live stream. On the other hand, you can go for a wired encoder which will ensure that the stream flows uninterruptedly at all times.

Scientists Have Developed A Tiny Camera That Can Take Photos Of Your Brain

Scientists Have Developed A Tiny Camera That Can Take Photos Of Your Brain

Scientists have developed a camera lens the size of a grain of salt that can capture higher-quality photographs of the insides of our bodies than existing technology.

Cameras are now everywhere. They’re on computers, phones, doorbells, and other devices, and they’re so little because light intensity sensors have been miniaturized.

Traditional imaging systems, on the other hand, rely on a set of lenses to make pictures less fuzzy, and they place a physical restriction on how compact cameras may be.

Meta-optics is another technique. These employ hundreds of thousands of tiny “nano-antennas,” which are microscopic structures that can catch and re-emit light on a nanometer scale. A sheet of paper is approximately 100,000 nanometers thick.

Cameras based on this technology have previously been developed, but their pictures have often been poor or had small fields of view. Now, researchers have suggested “neural nano-optics,” a hybrid of the previous technologies with machine learning.

According to the researchers behind it, it is capable of capturing full-color shots with a 40-degree field of vision, due in part to a deep learning computer program that aids in image construction.

According to the team’s assessment, the image quality is “on par” with that of a commercially available compound lens 550,000 times larger.

The accompanying photographs appear to illustrate that the brain nano-optics images are comparable to the compound lens images, which include photos of fruit dishes, chameleons, and flowers.

The small camera “may permit new possibilities” in medical imagery within people’s bodies, including brain imaging, according to research explaining the technique. According to the study, numerous of these cameras might be distributed across surfaces like “optical ‘dust.’”

According to a news statement from the Princeton University Engineering School, the new optical system incorporating the nano-antennas is just half a millimeter wide.

“It’s been a struggle to create and set up these small things,” Ethan Tseng, a computer science Ph.D. student at the university who co-led the research, stated in a press statement.

“It’s difficult for this specific purpose of taking the big field of view RGB photos because there are millions of these minute microstructures, and it’s not apparent how to build them optimally.”

To get around this, co-led author Shane Colburn of the University of Washington’s Department of Electrical and Computer Engineering created a computer simulation that evaluated several settings automatically to assist them to locate ones that worked.

On November 29, their study, titled “Neural nano-optics for high-quality thin lens imaging,” was published in the journal Nature Communications.

MTN Exposes Akufo Addo’s Government; Reveals How They Were Forced To Increase Call and Data Charges

Ghanaian Telecommunication Giants, MTN have offered an explanation as to the ridiculous upward adjustment in their call and data packages in recent times.

Subscribers of MTN would have realized in recent times that the network’s prices for Mashup and internet are not like before as customers are now paying more for less talk time and data access.

However, in an explanation offered by one of the Network’s Customer Relations personnel on social media, in response to a query from a customer, MTN is basically not at fault here.

According to the said customer service representative, the Network is only responding to an order from the regulator (Government) to adjust their prices upwards in order to allow for a fair competition with other networks.

This has led to many Ghanaians wondering the sense in such a directive by the regulator considering the fact that competition is supposed to bring a reduction and not an increase.

Meanwhile, Government as the regulator, is yet to respond to the issues.
