Before HTML5 was launched, videos were played in the browser with the help of Flash like a plug-in. The HTML5 video is exciting for web designers from across the globe.
Dozens of elements and attributes for building the websites are supported by the specifications. Multimedia audio and video format tags are included in these features.
The audio and video elements of HTML5 support playing of media without the need of plug-ins.
The media is handled by video and audio codecs. There are different browsers available and all these do not support media formats of the same type to implement HTML5 on the web.
All new versions of major browsers can display video using HTML5. The media formats supported by HTML5 audio and video elements are the WebM, Ogg Theora Vorbis, MP4 H.264, MP4 Flac, MP3, Flac etc.
Here are few things that developers should know about HTML5 on the Web
• Major video types supported by HTML5 are the MP4, WebM and Ogg/Ogv.
• WebM and Ogg work for Mozilla Firefox, Google Chrome, Opera. MP4 will work for Safari and IE9.
• Since most users are turning to mobile, there is need to adopt HTML5 for the media types.
Let us now know how to play videos in HTML5. The controls attributes of HTML5 video adds controls such as volume, play and pause. Include height and width attributes to prevent flickering while the video is loading.
The autoplay attribute helps the video to start automatically. Three supported video formats are available and these are the MP4, Ogg and WebM. For the video element, HTML5 defines the DOM methods and properties.
This will help the user to set the volume and duration as well as allows loading, playing and pausing the video. Important HTML video tags are <Video> which defines the video, <source> that defines multiple media resources for audio and video elements and <track> that defines text tracks in media players.
Closed captions and subtitles can be added easily to HTML5 in simple steps. HTML5 video display closed captions from WebVTT file. To get the file, submit the video file for transcription and captioning to a professional company.
Upload the caption file you get to the folder as your video. Add track element in the video HTML code. Save changes and update webpage.
HTML5 video is highly searchable, unlike the Flash video. All the modern browsers support that HTML5 video. The advantage of using HTML5 video is that the video will be viewable on mobile devices.
Flash is not supported by most mobile devices and if people do not use HTML5 videos for their websites, they may lose views.
Integrating HTML5 video to the website requires only less code. Loop, autoplay, controls and poster tags can be used.
There is no need to build a video player to add video to the web and it can be done very quickly so that developers can save time.
HTML5 is the latest version for building websites the features are similar to the previous versions but it comes with various new features.
There are built-in video and audio playback and there is no need to use any third party programs.
Another interesting feature is offline caching, Users will not need active internet connection to load elements of the webpage if they have already visited the site earlier.
Another reason to use HTML5 is the mobile optimization for mobile website and application creations.
When it comes to HTML5 video, it is constantly compared with Flash technology. Let us see some differences between them here.
HTML5 video advantage is in mobile space. HTML5 video content offers better battery life than Flash for smartphones, tablets and laptops.
Coming to desktop space, many versions of Flash are available and newly created videos do not play on older versions of Flash. There are also some issues with HTML5 video.
The technology is not yet supported universally. Seventy-five percent of the videos on the web are viewed using Flash. HTML5 video playback was added to YouTube in only 2011.
Eighty-five percent of the most visited websites use flash on their websites in various forms.
Running speed of HTML5 is high on different platforms and slow with Flash. Finally, HTML5 video is definitely the future but the days to abandon Flash are still down the road.
