Note: Most of the processes described in the below articles talk about video, but audio content works in such a similar way that they are generally applicable to audio too.
Planning
- Planning your transition from Flash video to HTML5 video
- Transitioning from Flash to HTML can take several months and may require new skills and software. This guide shows you how to plan for that transition, and contains two main parts, Content audit and Decision points.
Process
- File format conversion
- Once you've planned out what you want to do, the first step is to convert your video files into formats compatible with HTML embedding.
- DRM and authentication
- If your media requires authentication/rights to access, you'll need to work out how to hook up the necessary DRM and authentication mechanisms.
- Video advertising
- You may also want to incorporate advertising into your video delivery system, via an ad network.
- Distribution
- A CDN is a popular choice for effective delivery of media content.
- Video and audio players
- There are a number of ways to play back web media depending on the scale of your needs and whether you need ad integration and digital rights management.
- Subtitles and closed captions
- Just as audio and video may need transcoding for the web, subtitles and closed captions may also need to be converted and made available.
API reference
- The
<video>and<audio>elements - The basic elements that allow embedding of media into web apps.

- Media Source Extensions API
- The Media Source Extensions API (MSE) provides functionality enabling plugin-free web-based streaming media. Using MSE, media streams can be created via JavaScript, and played using
<audio>and<video>elements. - Credential Management API
- The Credential Management API lets a website store and retrieve both user and federated credentials. These capabilities allow users to sign in without typing passwords, see the federated account they used to sign in to a site, and resume a session without the explicit sign-in flow of an expired session.

Firefox handles many types of audio and video content on web pages. This article explains which media formats you can play and how to control, save, and open them.
Table of Contents
- 1Supported formats
- 2Audio and video controls
Since the use of certain audio and video file types is restricted by patents, a third-party application is required to use them. Firefox, however, is able to play natively open media and some types of patented media.
Open media
Firefox can play the WAVcontainer format (.wav, .wave file types) containing uncompressed audio in PCM at 8 or 16 bits per sample.
Vorbis audio, Opus audio, Theora video, and VP8 video are free audio/video compression formats for use without patent restrictions. They can be viewed in Firefox if they are embedded in the following container formats: Ogg (.ogg, .oga, .ogv, .ogx, .spx, .opus file types) or WebM (.webm file type).
Firefox also supports FLAC (Free Lossless Audio Codec) playback (.flac file type) and MP3 playback (.mp3 file type).
Patented media
AAC and H.264/MPEG-4 AVC are patented audio/video compression formats. They can be viewed in Firefox using built-in OS libraries (so neither Mozilla nor you need to pay a fee) if embedded in the MP4container format (.mp4, .m4a, .m4p, .m4b, .m4r, .m4v file types).
Firefox supports WebM/VP9 video on systems that don't support MP4/H.264.
Tip: In order to test your system, some sample video files are available in the “Video For Everybody” Test Page at camendesign.com.
