基督教费尔德曼: The two main codecs I'm going to talk about are VVC and AV1, and I wanted to shortly introduce who's doing these.

对于VVC, that is the Joint Video Experts Team, the ITU and MPEG who joined together to do this standardization. And they also joined together for AVC and HEVC. So, the standardization goes on through these parent bodies, and if you want to 提出一些 in the standardization, if you want to get your patented technology in to a codec, you have to be a member of either of these organizations, 然后你就可以进去了, 提出一些. 但总的来说，它是非常开放的. You just have to be a member, then you can propose stuff. Also, the documentation and the software are all open. It's all freely available on the internet. 只要去, 这里有一些链接和参考资料, 去那里, you can read thousands of standardization documents if you want to. 一切都是开放的.

Of course, the goal of the standardization here is always a licensed model. So 最后, you will have to pay for it. 这就是我的想法? 你获得了专利技术, 并达到标准, and 最后 you earn your money back by somebody paying for the licensing of that. AV1，这有点不同. It's mainly done by the Alliance for Open Media, which is technically a non-profit industry consortium. 主要贡献者, 尤其是对AV1, 是谷歌, Mozilla, 和思科, who were all already working on open source, 免费视频编码技术, 他们就这样联手了. I don't want to exclude the work of anybody else. There are other companies as well who contributed. These are just the biggest companies contribution-wise, who contributed here.

Also, the specification of the software is all open source. And the idea here, is not to make money by licensing the codec. 所以使用编解码器是免费的. You can use it for whatever you like, it's free.

当然, 你必须同时考虑两个身体, both standardizations are in it for the money, they're not doing it because of the good of the world. For the companies which are in the AOM, 主要是, 他们想节省终端成本, 当然, 最后. So they want to stream the same quality at lower bandwidth and save money, save a lot of money.

The licensing situation, that's a big one. And actually, I'm an engineer, so I'm just gonna try to state facts, or mostly facts here. 对于VVC 当然, the standardization is still going on. 这是未知的. 我们不知道. It will not be free, you will have to pay for it. 有多少? 没有人知道. One of the problems is that the HEVC situation--that's what I called it--could repeat. So，在… standardization body, no change to the standardization has been done. It could theoretically happen, the same thing with HEVC could happen again. No measures have been done to prevent that, unfortunately.

Also, JVET is not directly responsible, they are just a technical committee. They just take about and think about the techniques. 他们不考虑专利. So it would've been, the responsible ones would've been the parent bodies, but nothing changed there.

There's also the Media Coding Industry Forum. 我们只是想推广VVC, and try to think about how to implement licenses, 但他们没有任何实权. 这是最大的问题. They can only propose, bring together, and talk to people, and try their best.

如何用FFmpeg制作VVC

Anytime you start working with a new codec, there are some fundamental tests that you should run to achieve optimal performance/quality optimization. 在本文中, I'll take you through those tests while encoding VVC using a version of FFmpeg that includes the Fraunhofer VVC codec.
