You can use Adobe Flash with h.264 and AAC. It is the only solution with wide support. Everything else will cause technical problems for many users. There is no official and recognised standard about video or audio on the Internet. Every browser has its own.
As others have mentioned, FLAC is the thing for the absolute best (lossless) audio. However, there's something to be said for also offering high-quality (>300kbps) MP3 or Ogg Vorbis files; they'll be smaller and good enough for many users.
For video, h.264 seems to be the current winner, albeit with a complex legal landscape.

FLAC 是无损的，因此它应该提供您需要的所有质量。文件大小将大于有损格式（例如 .MP3）。
我将使用 H.264 （MPEG4 第 10 部分）对视频进行编码。它是目前可用于高质量视频的最佳编解码器。
FLAC is lossless, so it should provide all of the quality you need. File sizes will be larger than lossy formats (like .MP3).
I'd encode the video using H.264 (MPEG4 part 10) for video. It's the best codec available for high quality video right now.
您可以将 Adobe Flash 与 h.264 和 AAC 结合使用。这是唯一得到广泛支持的解决方案。其他一切都会给许多用户带来技术问题。互联网上没有关于视频或音频的官方且公认的标准。每个浏览器都有自己的。

正如其他人提到的，FLAC 是绝对最佳（无损）音频的选择。然而，还可以提供高质量（>300kbps）MP3 或 Ogg Vorbis 文件；它们会更小，但对于许多用户来说已经足够好了。
对于视频，h.264 似乎是当前的赢家，尽管其法律环境很复杂。
