The great news is that most software packages that are designed for streaming come with encoders as part of the application. Let’s take a look at some of the options you have when it comes to encoding your video data for streaming. You can read more on this in Dacast’s What is HLS Streaming and When Should You Use It article. The latter cuts up videos into smaller chunks to transmit quicker and is the most common way to live-stream now due to their specifications being more easily modified – they’re also considered faster and more reliable than other methods. Most encoders use RTMP (real-time messaging protocol) or HLS (HTTP live streaming) formats. The aim is usually to match your output to the average viewer’s setup – the higher your bitrate, the more bandwidth your audience needs to be able to view it properly. If you’re streaming video online, your viewers will need to have fast-enough bandwidth to be able to watch it without issues. To Encode Your Streaming DataĪll you really need to know if you’re just getting started is that an encoder will translate and communicate your media (audio, video, graphics) in an appropriate format for your desired output. Note: Dacast have a really nifty Video Encoding Glossary which you might want to bookmark to help with some of the definitions, if you’re unsure. How you choose to encode your data will depend on the output, as with all conversions it’s a tradeoff and balancing act between file sizes, compatibility and quality. Video (and we’re including audio and graphics here too) needs to be converted in order for it to be compatible with most potential outputs, and that’s where an encoder comes in. Encoding is part compression and part making a video as universal as it can be by creating compatibility with as many devices as possible. Raw uncompressed video files are huge data behemoths, but you can watch films over your regular internet connection in high-definition just fine, and that’s because the data has been encoded.
