使用 Xuggler 时提高 Theora 的视觉质量
我正在寻找正在使用 Xuggler 制作使用 Theora 编码的视频的其他用户。我尝试了很多不同的选项来使用预设来获得“良好”的质量,但均无济于事。我希望获得接近使用 Miro 转换器工具默认值生成的质量。遗憾的是,网络似乎没有太多可说的,除了我们都应该“使用 ffmpeg2theora”,这在使用 Xuggler 时不是一个选项,在这种情况下我必须使用 Xuggler。

I'm looking for fellow users, who are using Xuggler to produce video encoded with Theora. I've tried a lot of different options to get "good" quality using presets to no avail. I would love to get quality anywhere close to what I can produce with the Miro converter tools defaults. Sadly, the web doesn't seem to have much to say except that we should all "use ffmpeg2theora" which is not an option when using Xuggler, and I have to use Xuggler in this case.

同事/客户在相关项目中找到了解决方案。该解决方案非常简单,由以下三行代码组成:

This forces Xuggler to encode using a constant bitrate of 200kbps and with a frame rate of 25 fps. I hope this helps my fellow Xuggle users out there.
A solution was found by a colleague / client on a related project. The resolution is surprisingly simple, and consists of the following three lines of code:
