罗伯特•莱因哈特: SRT相对较新. I actually have a client that's having some problems with SRT and it's usually from server to server.

Teradek has got some SRT implementation in their encoders; Wowza supports SRT. I believe Haivision originated that spec and has made it open-source, 但它可以取代RTMP.

Philip and I have been joking about how some of these acronyms are poorly chosen. There was already something called SRT in video, related to caption files. 我不知道他们为什么选SRT.

当我们用谷歌搜索的时候, we might come up with a whole different tech stack than what we're talking about here. I would just say search for secure reliable transport if you want to find more 信息 about it.

Again, it's meant more for server-to-server. 这是一个推目标. I have a client right now that's approached me that is pushing from North America across the pond to Europe and they're using SRT to connect, and they were having issues with it because it was a relatively initial implementation by Wowza, 我说, “你为什么要用SRT? 你为什么不回RTMP呢?”

“我们也遇到了RTMP的问题.”

“If you're having issues with both RTMP and SRT, I don't think you can blame the transport, it sounds like something else is going on here, 因为如果RTMP超时了, then you probably have other network problems going on.”

Anyway, that's just a recent experience I've had with SRT that didn't seem to work out as well. But I do think that what I like about SRT is--I haven't really seen this talked about as an HEVC carrier but--since it is a push, 从设备中取出, 我很想看到一个装置, and maybe Teradek's already there with Wowza, 但我还没有测试过. But if I could do HEVC over SRT from a remote location for a webcast, 那太好了, 但当我打开我的AJA HELO编码器, 或者我打开视频编码器, I'm not seeing an SRT path there for HEVC. I did test a Cube from Teradek over a year ago that I believe I did not see an SRT update for at the time, so I had to do a UDP transmission as well for HEVC from that Teradek.

This is promising for encoders and media servers and media servers to talk to each other. 就我所听到的而言, it is not something that we would be using any day soon for client playback. It's not like I'm going to put some SRT URL in browser, because, again, that's a long road, right? 我的意思是, even if Haivision gives a lot of resources to it, I don't think they're going to convince all the browser vendors to just magically insert this by next year into their product.

Using SRT to Enhance Remote Production Quality

Epiphan's George Herbert describes how Epiphan uses SRT (Secure Reliable Transport) and remote contribution encoders with multiple remote guests to upgrade streaming quality substantially over what Zoom provides in this clip from his presentation at 流媒体 Connect 2021.
