多位比特率在Windows上使用FFmpeg播放HLS [英] Multi bitrate live HLS with FFmpeg on Windows
问题描述
我正在尝试将一个直播流编码到苹果HLS for Windows上。我正在看不同的选择，并且可以做到这一点，但是不能支持HLS的CDN分发，只要我能看到。此外，它花费了很多钱。
我发现这个网站是： http://www.espend.de/artikel/iphone-ipad-ipod-http-streaming-segmenter-and- m3u8-windows.html
我现在可以轻松地设置单个比特率流，但我的目标是一个适应性的多比特率直播流。可能吗？对于VOD内容，可以轻松地创建不同的品质，然后在新的m3u8中连接到他们，但是如何在现场完成？
我当然可以设置三个优质的实时流，并将它们连接到一个m3u8中，但是在这种情况下，我将如何将它们与GOP进行对齐？
我的初步想法是拥有一个ffmpeg实例创建所有质量，并将这些输出重新流向新的ffmpeg实例，只需将其重新分配并分配给分段器。但是我需要一些在实例之间本地流的方法。可以这样做吗？
如果有人有一个很好的解决方案，或者可以链接到其他能够在Windows上实现HLS的软件，我会欣赏任何输入。 p>
有一个美好的一天！

只是让人们知道，我最终使用 http://www.ioncannon.net/projects/http-live-video -stream-segmenter-and-distributor / 在一个linux虚拟机上，它的效果非常好。编译过程中遇到麻烦，但有几个问题可以解决这些问题。
I am trying to encode a live stream into Apple HLS for iPhone on windows. I was looking at different options and wowza can do it, but doesn't support CDN distribution of HLS as far as I can see. Plus it costs a lot of money.
What I did find was this site: http://www.espend.de/artikel/iphone-ipad-ipod-http-streaming-segmenter-and-m3u8-windows.html
I can now set up a single bitrate stream easily, but my goal is an adapive multi-bitrate live stream. Is it possible? For VOD content it can easily be accomplished with creating the different qualities then linking to them in a new m3u8, but how would this be done in live?
I can of course set up three quality live streams and link to them in an m3u8, but how will I get them GOP-aligned in this case?
My initial thought was to have one ffmpeg instance create all qualities and re-stream those outputs to new ffmpeg-instances that just remux and pipe to the segmenter. But I would need some way of streaming locally between instances. Can that be done?
If anyone has a nice solution to this, or can link to other software capable of live HLS on windows, I would appreciate any input.
Have a great day! Regards Carl
Just to let people know, I ended up using http://www.ioncannon.net/projects/http-live-video-stream-segmenter-and-distributor/ on a linux virtualbox and it works great. I had trouble compiling it, but there were a couple of forks that fixed those problems.
