What is an Encoder?

RTMP encoder
An encoder converts video file types to make them easier to broadcast.

A live video encoder is a tool that converts a video from the RAW format to the digital format. On one end, video footage from a camera is fed to the encoder. This footage is converted into a different format in real-time. The purpose of the conversion is to prepare the video to be broadcasted over the internet. 

You can use either a hardware encoder or a software encoder. Each comes with a set of benefits and drawbacks. 

Hardware vs. Software Encoders

Hardware vs. Software Encoders
You can use either a hardware or software encoder when you live stream.

There are two types of encoders: hardware and software. A software encoder is a program that works with your online video platform. It uses your computer’s processing power to encode and deliver the video.

A hardware encoder is a dedicated device. They come in various forms. Some are small and suited for mounting on a camera. Others are backpack-mounted or rack-mounted for use in studios or broadcast vehicles.

Hardware encoders are typically considered superior to their software counterparts because they produce a higher quality stream. However, hardware encoders are typically a much larger investment than software encoders. 

Depending on the type of broadcasting you are doing, the investment in the hardware may be worth it. Since there are software encoders for under $100, it is worth testing them out if you’re not sure whether or not you’re ready to make the investment.

What is RTMP Streaming?

RTMP streaming is a method of streaming that is different from its predecessors in the sense that it maintains constant contact between the video player and the server. This constant contact makes RTMP streaming very robust and reliable.

For many years, Flash Player and RTMP worked hand-in-hand to produce ultra-low latency live streams.

Many consider RTMP streaming outdated since it was so closely intertwined with the Flash Player technology, which is completely dead in terms of OTT streaming today. However, the RTMP technology lives on via RTMP encoders.

Common Video Streaming Protocols

Now that you have a better idea of the purpose of video streaming encoders, let’s go a quick comparison of the most common video streaming protocols.

RTMP Streaming Protocol

RTMP Real-Time Messaging Protocol
RTMP is a live streaming protocol that transmits video files from the encoder to an OVP.

Most encoders use the format RTMP. RTMP stands for Real-Time Messaging Protocol. RTMP streaming is a delivery method designed for live-streaming. It’s not a codec, but RTMP commonly uses the H.264 codec. Simply put, the purpose of a live streaming encoder is to encode video feeds into RTMP or another live streaming protocol and send them out to a streaming server.

The RTMP protocol is no longer commonly used to deliver streams to viewers. Most often, a modern option like HLS streaming protocol is preferred. Since RTMP is still the standard for delivering your streams to your online video platform, the two work together to make the magic of live streaming possible.

To put things into perspective, your video follows this path:

  1. Recorded by camera
  2. Fed to RTMP-enabled encoder and prepared for delivery using the RTMP 
  3. Sent to your online video platform
  4. Prepared for delivery to viewers using the HLS protocol
  5. Sent to viewers

This path is traveled almost instantaneously. RTMP and HLS rely on one another to bring your live stream to your audience.

HLS Streaming Protocol

HLS stands for “HTTP Live Streaming.” It is a streaming protocol that was originally designed and used by Apple. HLS is actually responsible for the phasing out of Quicktime.

HLS works by chopping up videos into smaller clips to make them easier to transmit over the internet.

Although it is praised for its compatibility, HLS has about 15-30 seconds of latency.

RTSP Streaming Protocol

RTSP, also known as Real-Time Streaming Protocol, is a lesser-known protocol for streaming video online.

This protocol was designed to control the streaming servers used in entertainment and communications systems. RTSP servers sit between the live stream and the viewer, issuing “play,” “pause” and “record” commands.

When the RTSP controls the server to client connection, video on demand streams are used; when it controls the client to server connection, RTSP utilizes voice recording streams.


RTMP and RTSP are both streaming protocols, meaning they are sets of rules that govern how data travels from one system of communication to another. If the video data you’re trying to send to your viewers is a car, then the streaming protocol is the roads that the car takes to get from one place to another.

Choosing between RTMP vs RTSP streaming protocols greatly depends on your individual business needs and how many extra steps you are willing to take to make your content playable on your website.


As we mentioned, RTMP and HLS work together to bring streams to life. They have complementary functions.

RTMP transmits the video from the encoder to the online video platform.

HLS transmits the video from the online video platform to the viewers’ devices.

Configuring Your RTMP Encoder in 6 Steps

RTMP Encoder
Follow these 6 steps to set up your RTMP encoder.

In order to prepare for a smooth live stream, you have to make sure all of your RTMP settings are properly configured. 

Here is a 6-step walkthrough for configuring your RTMP encoder.

1. Connect Your Video Sources

Setting up your video capturing equipment is an important step in broadcasting.

The first step is to connect your video sources. The method that you use to do this differs depending on whether you’re using RTMP encoder hardware or a software encoder.

If you’re using a hardware encoder, the method is simple. Generally, hardware encoders have dedicated cable inputs for video cameras. These may include SDI inputs as well as HDMI. Additionally, some encoders support cameras via wifi. Generally, these systems are plug-and-play.

The method for connecting cameras to software encoders may be a little more complex. Generally, this involves installing a “capture card” on a desktop computer. Laptops and other devices can use external capture cards that often attach via USB.

Once your camera is physically connected to the encoder, it should be auto-detected. You can select it from a dropdown menu of “inputs.”

2. Create a New Live Channel and Connect Your OVP

The next step is creating a new live channel. This actually occurs via your online video platform. 

To complete this step with Dacast, follow these steps:

  1. Log into your account.
  2. Click “Live Channels” in the left-hand sidebar.
  3. Click the orange “Create” button in the upper right.
  4. Enter a title for your new live channel, then click “Add New.” 
  5. Click the “Encoder Setup” tab in the top-center of the screen
  6. This tab shows three simple setup steps. The first step involves selecting a publishing point (optional) and selecting a bitrate, resolution, and aspect ratio (also optional). The settings you select in your encoder will override these settings.
  7. The second step allows you to select an encoder. Select the option that matches the encoder you’re using, or select “other RTMP encoder.”
  8. Finally, on the right side of the window, a dialogue box will appear with a stream URL, a login, and a password. Leave this window open.

After your new live channel is created, you’ll need to link your encoder to Dacast. This involves navigating your encoder settings, usually labeled something like “Broadcast Settings” or “Output.” Enter your Dacast stream URL, username, and password here. Your encoder is now connected to your online video platform.

3. Select Video and Audio Encoding Options

The next step is to select your video and audio settings. First, select a resolution, such as 1920 x 1080 (full HD) or 720 x 480 (standard definition). In this step, you’ll also select a bitrate and a codec. It’s most common to use H.264 video compression, or advanced video coding (AVC) for video, and AAC for audio.

Get an embed code so that you can run a test before your broadcast.

At this point, we recommend that you carry out a brief test stream. A test stream begins with embedding a video player on your website. Since this is just a test, you may wish to use a private webpage.

The exact method for embedding live streaming video to your website depends on the online video platform you’re using. If you’re using Dacast, we provide simple embed codes that can be pasted into any website to display your video. 

5. Conduct a Test Stream

Now, you’re ready to begin a test stream. Head to the Dacast back office and hit the toggle to turn your live channel “On.” Turn on your cameras and start recording. Since this is a test, it doesn’t matter what you’re streaming. Begin your live stream from the RTMP-enabled encoder you’re using to stream.

Visit the web page you embedded your video player on and take a look at how the stream is working. Test it out with both a desktop computer and a mobile device.

If you’re having problems here, you’ll need to do some live stream troubleshooting. Troubleshooting can be frustrating, so try to be as systematic as possible. Check every link in the system. Ensure that cables are connected and that settings are correct. If you need more help, consider contacting Dacast technical support.

6. Start Streaming

You’ve now fully configured your RTMP encoder and are ready to begin live streaming. Feel free to now copy your video player over to whatever web page or site you plan to stream on. 

You are now ready to begin your live stream.
