Why do streams lag




















Antiviruses are programmed to stop any software that is leeching your bandwidth in the background. As a streamer, upload and download is constantly in progress and thus falls on the list of things that are stopped by the antivirus software.

There are two workarounds for this. Either you can switch it to gaming mode while streaming twitch or you can deactivate it. The latter is an option for all antiviruses while the former is only applicable in new and updated antivirus software. Internet connection is a bigger problem and is comparatively difficult to know and solve. As a streamer, you have to be very careful about it. Having a good internet connection is a must and also to make sure that you are getting a consistent bandwidth throughout the day.

The best way to check your internet speed is by running a quick and simple speed test. Just check your internet through a speed test whenever you are going over to twitch. This speed test will give a good idea of how the internet is performing. If the internet connection is slower than expected then doing a few tweaks would greatly help.

The reason Twitch won't load for you might also be related to issues in a specific country or territory. There's a quick fix for that—simply use a VPN.

Alternatively, if you already use a VPN, this might be the issue behind Twitch streams not loading. In such a case, you might disable your current VPN and see if anything changes for you. Probably the easiest step to take in finding a solution for Twitch lagging is to try using a different browser. If your twitch stops running for unknown reasons or doesn't even start then it's probably due to your browser.

Updating it is also a solution to the problem but if you are too lazy to do that then probably switching over to a different browser e. Firefox, Opera is the best thing for you. This mostly happens if you are using Chrome as your sole browser. Chrome is notorious for taking up a lot of memory and thus leaving little to nothing for your stream.

You can simply solve this by going to your Chrome settings and turning off "hardware acceleration. Twitch lagging mostly happens if you are using Chrome as your sole browser. Open the Google Chrome browser on your computer by double-clicking its desktop shortcut or by searching for it in the Start menu. Click on the three horizontal points at the top right of the browser window.

It should read: Customize and control Google Chrome when you float above them. This opens a drop-down menu. Click on the Settings option at the bottom of the drop-down menu and scroll down this page to the "Advanced" button. Make sure you click on it. Scroll down the new page again until you reach the System area. To disable hardware acceleration in Google Chrome, clear the Use hardware acceleration checkbox next to the input. Sometimes videos don't play smoothly because of improper conversion, video file corruption, improper download, and downloading from unverified sources.

These deep-rooted technical problems require video repair tools to correct video playback. There are lots of tools out there that can help you to repair your corrupt videos. Wondershare Repairit - Video repair is one such tool.

It supports two repair modes. Quick repair is to repair various video errors. The advanced repair can repair your corrupt videos by analyzing the data and technology of the sample video shot by the same device. Below are some key features of Wondershare Repairit:. Add the video you want to repair on the software's interface. This step applies to videos you want to repair using one of the tools repair modes: Quick Repair.

This will simply remove the errors in your corrupted videos once you click "Repair". Recoverit Video Repair lets you preview the files from which errors have been scanned and removed. Next, you can save the files when you click "Save".

This step is only for the second repair mode: Advance Repair. This latency can range from extremely low thousandths of a second to values closer to the duration of a video frame.

Changing encoding parameters can lower this value at the expense of encoded video quality. The encoded video takes time to transmit over the internet to a VDS.

This latency is affected by the encoded media bitrate lower bitrate usually means lower latency , the latency and bandwidth of the internet connection, and the proximity over the internet to the VDS. Since the internet is a massively connected series of digital communication routes, the encoded video data may take one of many different routes to the VDS, and this route may change over time.

Because these routes take different amounts of time to traverse and the data may be queued anywhere along the route , it may arrive at the VDS out of order. A special software component called a jitter buffer reorders the arriving data so it can be properly decoded. When configuring the jitter buffer, one must choose a maximum time boundary inside of which data can be reordered. This time boundary provides the latency of the jitter buffer. As the latency is lowered, the risk of losing late data increases — while choosing a higher latency ensures more late data is recovered.

In order to provide a quality viewing experience across a range of devices, a good streaming provider should provide ABR. There are two general ways to accomplish this: Either the encoder streams multiple quality levels to the VDS which are directly relayed to viewers , or the encoder sends a single high-quality stream to the VDS, which then transcodes and transrates it to multiple levels.

Typically, the transcoding and transrating takes about as long as a segment of encoded video more about segments later , but it can be faster at smaller resolutions and lower bitrates.

The two differ in their latency and scalability. Understanding these differences is integral to choosing a streaming solution.

They can potentially be very low latency as low as the network latency from the VDS to the viewer , however, their support for adaptive streaming is spotty, at best. Furthermore, scaling these protocols to large numbers of viewers becomes very difficult and expensive. They also have built-in support for adaptive playback, and have more broad native support on mobile devices. The way these HTTP-based protocols work is by breaking up the continuous media stream into segments that are typically 2—10 seconds long.

These segments can then be served to viewers by a standard web server or content distribution network. HTTP-based protocols are generally better suited to most live streaming scenarios due to better feature support and scalability. The disadvantage of these protocols is that the latency is at least as long as the segment length, and can be as bad as 3—4 times the segment length for example, iOS devices buffer 3—4 segments before even beginning to play the video.

Whether viewing on a phone, a computer, or a TV, it takes time to decompress the media data and render it on the screen.

This latency is determined by the capabilities of the viewing device. A streaming solution that uses non-HTTP-based protocols can achieve a lower latency. Per our estimates above, latency will likely be in the range of about 1. However, this solution will not scale well beyond about 50— simultaneous viewers. A streaming solution that uses HTTP-based adaptive bitrate mechanisms will have a slightly higher latency range about 3.

Realistically, it will usually be in the 15—45 second range. Since this approach uses HTTP-based mechanisms that can leverage off-the-shelf CDNs, it can theoretically support a very large number of simultaneous viewers without difficulty. Some attributes of your total latency may be within your control. Your encoder settings, the jitter buffer, the transcoding and transrating profiles, and segment duration may be configurable. At BoxCast, we take great pains to automate as many of these choices as possible to maximize your stream quality and ensure a delightful viewing experience.

In addition to automating these choices, we make it possible for you to broadcast high-quality video — even when you're set up in less than ideal networking conditions.
