Video Streaming: What is, How Does it Work, Challenges in App Development
Looking at the modern tendencies of the network’s development and Internet speed increase the services which work with video content gain popularity. Live video streaming allows solving such issues as increasing brand recognition, engaging the audience from all over the world, growing traffic, generating leads faster, establishing real-time interaction with potential clients, etc. Though this cutting-edge technology allows receiving multiple positive results in a short time, it carries lots of challenges to those, who intend to apply it through a custom-built solution. Let’s look closer into the matter.
Playing a video file online looks like a simple task, but it’s only at first glance. It can be compared with the work of a simple computer, which contains video files. The access to them can be received with a simple link. Actually, such a variant really exists and has a right to, but it’s wrong. First, let’s find out what video streaming is and how it’s realized.
How to Make a Video Streaming Website: Technical Implementation
Generally, everything looks like it’s described above with video streaming platforms. So, what does video streaming mean? There is a remote server, which can be accessed from the net and on which certain video files can be uploaded, there is also an open API for getting the links to the video. However, it should be considered that video files should be prepared for uploading; it’s realized both on the client and on the server side.
Traditionally the preliminary files compression or their conversion to the appropriate format occurs on the client side with the help of predefined codes. Such a preparation will simplify the player setup. It will be not necessary to configure it for different types of video, with different formats, codecs and the pitfalls of the budget segment devices. In addition to the potential bugs avoidance the compression reduces the size of the files which should be uploaded to the server.
Unfortunately, at present, the access to the high-speed Internet or WiFi is not always available. While in big cities this problem will not be a problem for the majority of users, at some points of high people density or out of the networks of the new generation reach one should consider that the users should be able to use the app and the service as a whole comfortably. A 10-megabyte file is much easier to download than a 100-megabyte file with a similar duration, especially when the connection speed is low.
After the video uploading, there should be server-side post-processing of the file. There are some common formats for video streaming: HLS (HTTP Live Streaming) and MPEG-DASH (Dynamic Adaptive Streaming over HTTP). Though the principle of their work is different, in fact, it is adding the keyframes to the video. These are the image frames that are taken directly from a video at regular intervals. When the video is rewind, the users see these frames.
To put it simply, it’s the pictures we see instead of the black screen at the moment when the video is being loaded. Along with the image, service information is added from where the file should be transferred further. Also, when playing a video, the quality of the client connection may deteriorate, so there are formats that allow choosing the video quality. Meaning that if the connection is good, the video will be demonstrated in its best quality and if the connection is poor, the video quality will be worse, but it will be played without permanent stops and pauses.
So as you can now see, even though the advancements of streaming technology are great, there are still hurdles to overcome. Fortunately, most of the tools to cope with the challenges already exist, however, there is a difficulty: to use helpful add-ons and components a high learning curve of the developer is required, and this directly affects the time it takes to implement this functionality.
Challenges in Video Streaming Development with a Tight Budget
Everybody should realize that video streaming service development requires huge financial investments. If you use the format mentioned at the very beginning of the article, you are likely to get the following challenges in video streaming development:
- Long time of the video files uploading to the server;
- Possible loading errors. This may be due to a timeout on uploading a large file;
- Long video buffering time due to the fact the file fails to contain additional details about the keyframes;
- Great server response time, since in case of the limited budget it will not be possible to add geo-distribution support. Not only should the possibility of geo-distribution, but also synchronization of information between servers be considered;
- Possible problems in the Asian network segment.
It is logical to assume that with a small budget, you cannot expect high servers’ capacity. So the technical aspect is the additional area of expenditure, which adds up to the cost of development and can exceed the client’s financial expectations. The average cost of video streaming service is approximately $80,000. Nevertheless, this figure is not absolute, as various factors can influence it.
The Client’s expectations
A limited budget often forces clients to abandon most functionality and build an MVP model that is not intended for heavy workloads. Unfortunately, most customers don’t realize that MVP is not a minimal viable product but a full-fledged service with fast access and maximum functionality just at a lower cost.
In the context of video streaming services, the client will expect fast content uploading, no buffering or any delays during video playback in case he is far from the server location.
It is very important to explicitly explain to the customer that an MVP variant in this context is more suitable for idea testing, or just for its demonstration to the investors, but not for the first product release. The main reason for not making an MVP variant release is that you may make a poor first impression on the users and it will be difficult to return their loyalty later.
There are many things you can save on a limited budget, but not when building a video content service.
