One of the biggest challenges that has faced live productions over the years is the Internet. The lack of network infrastructure has made it near impossible to use the Internet to send remote cameras or productions. Trust me, we live in Australia and understand just how hard it can be to send video over what seems to be a tin can pieced together with some fishing line and being held up by a Hills Hoist!

You may have a satellite truck at your disposal but not every one has that luxury! Haivision saw an opportunity to create a protocol that would not only allow for remote video to be easily transmitted, but also be utilized if you had an unreliable Internet connection. This led to the creation of SRT. SRT uses secure streams and easy firewall traversal to optimize streaming performance and deliver high-quality video over even the most unreliable networks.

Hey Haivision, friendly suggestion: it'd be nice to have this vid posted on YouTube instead of having to enter personal info! As a protocol, it is content agnostic, although the industry uses it along with an MPEGTS container, which is the de facto standard in broadcast industry.

It can also be used with TCP, which is more reliable but has larger latency. It also supports encryption and bonding. There is also a white paper which can be found here or there. A very good source of info is the SRT Cookbook. Short answer: NO or not yet? Long answer: None of the main streaming services support the SRT protocol for ingest. If you're using exclusively these services, no need to read further.

If you are able to set up your own streaming server, maybe redirecting your streams to the main services like Twitch or YouTube and are interested in achieving low-latency with improved network resilience, read on. The other category of users who could potentially be interested belong obviously to the professional broadcast industry.

This wiki entry can be considered as fairly advanced in that it requires access to a server and being able to set it up. The configuration of OBS itself ranges from easy to medium in terms of difficulty. Additionally, though it is technically not a server, FFmpeg can be used in listener mode to ingest an SRT stream. It won't be able to serve the stream as a real genuine server would do. In the same way srt-live-transmit can be used to listen to an srt or udp stream and relay to a final srt URL.

This could be useful to two pc setups although NDI is probably a more common solution. In a Media Source, uncheck 'Local File'.

Please comment below about missing information or errors. Posted by David Hay at PM 2 comments:. There are a few free video streaming services that support low-latency streaming over the internet, notably Mixer and YouTube ultra-low latency. Assuming that you are already using OBS for streaming to an external destination, we'll use the "recording" feature to send to Haivision's srt-live-transmit application.

The -v means verbose mode, which allows us to read what it is doing. I haven't done any testing, but I'm assuming that decreasing the Keyframe interval should decrease latency, and decreasing the Audio Bitrate is probably fine to decrease bandwidth usage.

Assuming that Git is already installed, to start using it with terminal commands we need to set up a couple of things: git config --global user.

This means that once a video signal is compressed, there is no further loss. As a practical example, generation 2 and generation of a decode-to-encode sequence would be identical.

Where we can use it? You can join apps and hosts to long chain without quality degradation. Also you can easy re-configurate your production workflow. All you need - good local-network it's not problem and not expensive instead SDI communications.

It does not provide any codec. SRT is codec agnostic. This protocol uses modern techniques only for one task: low-latency delivery of data not only video. Cooperation workflow:. So let me explain who is winner NDI codec was designed for perfect quality for many times encode-decode cycles. This table is bandwidth requirements for NDI stream. It's very heavy for Internet connection. Winner is Also it allows use modern codec like h for low-bandwidth transmission NDI: provides low-latency workflow between nodes inside Studio without quality degradation.

Like most websites our site uses cookies to ensure that we give you the best experience. GOT IT.Absolutely make the feature request for SRT Encoder support. Wirecast Feature Request Form. SRT would give us another option to use without the additional cost of zixi. SRT should be implemented similar to how NDI works meaning it should work a couple of different ways. There are many use cases however one would be that an event has different physical locations that are not on the same internal network so NDI may not be a good option.

Perhaps not directly related but some find this interesting regarding our Lightspeed Live Stream product and Closed Caption Insertion. If you've already requested it, please email using your case number and ask for a status update.

Hope this doesn't take the 6 years it took to implement ASIO. I have been learning about SRT streaming and would love for Wirecast to get on board and be apart of it. Love your product and have been using it for years. If you fill out the Feature Request Form and specifically ask about its status update we may be able to inform you.

Frankly you guys needs to step it up. This is something I could see myself walking away from your platform for.

Just being honest. Disappointed to see that your reputation for lagging behind innovative trends is well earned. There's an increase in demand for a variety of features so priorities are relative to the demands and also the complexity of implementation. Implementations also need proper testing as a premature release of a critical feature not thoroughly vetted in advance, would a problem.

I'd like to challenge you Craig. I think the demand for the features is unchanged. What we are seeing is an increased demand for video streaming overall. The people who are interacting now probably already had demand for newer more advanced features, but it was latent demand. I know of a number of users who have not been using Wirecast because of perceived functionality gaps Before my time, I am told that many people advised that Rendezvous was not ready for production use.

I hope that we can find the balance between delivering new features faster and stability and reliability of those features.

There was always demand for this capability It is just more visible due to the increased demand for video in general.

I sent in a feature request for SRT and received this encouraging reply. No word on availability. We are working on the ability to transmit via SRT for our upcoming release Wirecast Can you confirm if you are looking to ouput SRT or ingest it? We will document your request with our product development team for evaluation.

Feature requests are reviewed periodically and prioritized based on number of customer requests. I would like to add my voice to the feature request for SRT both incoming and outgoing. We are receiveing daily requests for assistance with streaming from all sectors; ability to ingest SRT from a small software module at the contributor end directly into Wirecast would be a game-changer for us.

If you broadcast weekly this can get tedious, so with a little bit of coding we can automate the process. This will require a F acebook account with admin rights to a page if you broadcast through that page as well as a G oogle account.

We are going to create a Google Spreadsheet with an associated Google Apps Script that will run every week to schedule your live video. In the last few weeks I have been to quite a few conferences around Alberta, and have been reflecting on the ideal conference size. A conference should involve information sharing and discussions or networking, the latter may be less possible at larger conferences.

There is an ocean of information available, but I'd argue that through the internet we already have that available. So perhaps the ideal conference size is between and participants. Large enough for a diversity of perspectives, but small enough to be able to meaningfully share those perspectives and get to know people. We tend to value growth as a measure of success, but perhaps we need other metrics. Similar to the Callysto nbgitpuller bookmarklethere's the code for a bookmarklet to open a Jupyter notebook from GitHub in Google Colab.

Copy that link and you can use it to open the notebook in Colab. If you prefer a bookmarklet that just opens the notebook in Colab rather than giving you a link to paste somewhere then use this one: ColabGitOpener As always, comment if you encounter any issues or have any suggestions.
