4. TONIGHT
5. At London <Video> Technology
6. The Biggest Contest of the Year
7. The Winner...
8. Will Win BIG
9. AND
10. Will be the Undisputed*... *Not so much undisputed...
11. UDP Media* Transport *Lies...
12. Introducing...
13. SRT vs WHIP
14. SRT
15. SRT Secure Reliable Transmission
16. WHIP
17. WHIP WebRTC HTTP Ingest Protocol
18. What is SRT ?
19. Secure Reliable Transmission
20. srt://foo.bar:9710 Add url params for encryption, identi fi ers, latency
21. Open Source Transport Developed by Haivision, currently released under the Mozilla Public License
22. It is an expired IETF Draft Which isn't necessarily a bad thing
23. Uses UDP Not TCP
24. Push or Pull
25. Supports encryption but isn't mandatory
26. Defaults to ~120ms latency
27. Controlled latency Which can o ff er more time to recover from losses
28. Typically used for Media But doesn't have to be
29. Usually transports MPEG-TS And all of its subsequent parts it supports.
30. But in theory could be used to transport anything
31. Widely Supported
32. FFmpeg GStreamer VLC
33. Vmix OBS
34. Platforms Support It Ingress and Egress Broadcast Bridge being one of them
35. The SRT Alliance https://www.srtalliance.org/members/ Now Over 600 Members https://www.haivision.com/about/press-releases/srt-alliance-surpasses-600-members/
36. Cloudflare Wowza Dolby Sony Microsoft Alibaba Cloud Tencent Cloud AJA Ateme Bitmovin Paramount Matrox Red 5 Pro Eurovision/EBU Over 600 Members
37. YouTube recently joined the SRT Alliance https://www.haivision.com/about/press-releases/youtube-joins-srt-alliance/
38. Their Interop Plugfest is 9-11 May! https://www.srtalliance.org/srt-plugfest-guide-what-you-need-to-know/ https://www.haivision.com/resources/webinars/srt-plugfest (i.e. right now)
39. What is WHIP?
40. WebRTC HTTP Ingest Protocol
41. https://foo.bar/whip/endpoint
42. WebRTC Signalling Protocol
43. Designed to simplify WebRTC Ingress
44. It is an IETF Draft
45. Is TCP Not UDP
46. Has a partner protocol called WHEP WebRTC HTTP Egress Protocol
47. It is Starting to Gain Traction With Implementers & Providers
48. Twitch Dolby OBS GStreamer
49. Ultimately is just SDP over HTTP
50. No Media what-so-ever
51. That's WebRTCs Job
52. So What is WebRTC?
53. A Collection of Protocols
54. Can transport Data & Media
55. Offering the lowest latency But it's not easily con fi gurable (called playout delay)
56. The Goal is always Real Time
57. Media travels as encrypted RTP
58. It is a Peer to Peer protocol But a server can be a peer!
59. Being P2P means handling NAT scenarios using ICE But that's less important when one peer is a server
60. Session setup using SDP strings Yes... voodoo
61. Mandatory encryption
62. Multiple Codec Choices
63. Works on every device with a web browser
64. But can work elsewhere too! (Osprey Talon Encoders for example)
65. Designed to get Media from A to B with as low latency as possible
66. So WHIP vs SRT
68. Technically...
69. It's not really a competition
70. The Real Competition is...
71. WebRTC vs SRT
72. WebRTC is coming from behind.
73. But WHIP enables open adoption
74. WebRTC has never had that.
75. And that is so exciting.
76. YouTube supports WebRTC ingress (From a browser with a webcam - maybe WHIP soon?)
77. For me... there isn't a competition
78. There's just more choice.
79. The right tool for the right job.
80. Which tool is right is down to your circumstances.
81. Choose wisely.
82. Both have Pros and Cons.
83. Ultimately...
84. You can't be sad that you now have more options when streaming
85. You can't be sad that you now have more options for receiving a remote stream
86. What do they both have in common?
87. Changes QUIC may bring
88. Exciting times in media delivery
89. Much Love.
90. Not war.
91. Thanks!
