NEW YORK – Adobe says it is still on track to launch the latest version of its Flash Player for smart phones in the first half of the year.

Adobe Systems Inc. was planning to demonstrate Flash 10.1 at the Mobile World Congress trade show in Barcelona, Spain, this week.

Flash is used to play Web videos and games. Mobile systems that will work with the full Flash Player include the BlackBerry, Google’s Android, Palm’s WebOS, Windows Mobile and Symbian, used on Nokia’s smart phones.

The online video delivery experience

When delivering online videos there are generally two distinct ways to do it. HTTP Progressive Download or Streaming. You may assume that all videos are streaming, but you’ll be surprised to know that most aren’t.

So what are these two methods? How do they differ? What are the advantages and disadvantages of both? Why would I want to use one method over another?

Progressive Download
All web servers are capable of progressive download. This is merely the method of a video file being delivered via HTTP to a browser. This is similar to someone downloading a file from your website. In fact the video is delivered in the same manner that an image, a CSS, a JS, PDF, or any other file on your web site is.

The real difference is that media players can begin to show the video while it’s downloading. For example, a FLV file being delivered via HTTP Progressive download will begin to play in your Flash Player as soon as a little bit of data is received by the browser. The same is true for Windows Media files. Quick Time will wait until the entire file is downloaded before it plays, unless the QuickTime player on the PC/Mac is set for progressive play. So be careful when posting QuickTime videos.

It’s quite obvious when a video is being delivered via HTTP Progressive Download. You will typically see the little status bar grow as the video downloads. You won’t be able to move the scrubber button past the amount that has downloaded already. This makes it impossible to jump to the end of the video before that portion has downloaded. If you have a slow web server or limited bandwidth or the end user is on a slow Internet connection, then it’s possible for the enduser to notice buffering.

Buffering occurs when the download can’t stay ahead of video. The video will stop while it downloads more. If you pause the video and it allow to download a large portion, then you can watch the video uninterrupted. In either case, this is a poor enduser experience, this is when you would consider using a CDN.

There is a technology called Psuedo or Seek streaming. This method utilized TCP/IP Range Requests to allow the user to jump to any portion of the video and the player will make a range request of the file to download that portion. This method is usually only for FLV videos and requires special services, or servers and custom Flash players to function.

When a video is delivered via HTTP, it is actually downloaded to the end users computer. This is good and bad. It’s good because if the person watches the video again, it’s already cached on their computer. It’s bad because it makes it extremely easy for someone to steal your content.

Finally, if someone only watches the first minute of your video but doesn’t stop the download, the browser will download the whole file and you will pay for the delivery of the file even though the person didn’t watch the whole thing.

Streaming Video
Streaming video requires access to a streaming media server. Some servers are Flash Media Server, Wowza Media Server, Windows Media Server, Darwin Media Server (QuickTime), Real Media Server. These servers usually require licensing and may cost several thousands of dollars.

Some well known streaming protocols are RTMP, RTSP, and MMS.

When a video streams, it is being sent via UDP protocol to a player on the end users compter. The user will have the ability to fast forward or rewind the video. The video isn’t being downloaded to the end users computer so it is less likely that the content will be stolen. Also if the user only watches 5 minutes of a 30 minute video, then you only pay for the delivery of 5 mintues, not the whole video.

The biggest disadvantage of streaming over progressive download is if the user watches the same video over and over you will pay for the delivery of it each time.  Videos are also streamed at what ever bit rate they are encoded at.  Keep this in mind when creating HD quality video.  8Mbps video may sound and look great, but most homes can’t sustain an 8Mbps connection.  If you have really high bit rate video, consider delivering via HTTP.

Most web hosting providers or Content Delivery Networks (CDN) will have streaming media servers available to use. Historically, Flash video was more expensive to deliver than other forms. Recently prices have compressed and you will find that it costs about the same to deliver Flash or Windows Media files. In the past I would have said if your video is more than 10 minutes in length deliver it via Stream and less do progressive. Since prices have come down, I would consider streaming for any length video since streaming typically begins to play faster than progressive.

If you are looking at using a service such as a CDN or Cloud Computing and they say you can stream your videos, confirm with their tech support that they are utilizing a streaming server and not just offering bandwidth.

If you are delivering Flash videos, then you should be delivering via RTMP or RTMPE protocol for streaming and http for progressive. Windows Media uses either MMS or RTSP. Quicktime and Real Media use RTSP.

I hope you find this article of interest? This is a good guide to help you through deciding to use streaming delivery of videos or HTTP Progressive Download.

You may be asking yourself, what is a Flash Player?  or Why do I need one?  I have my Flash videos, won’t Internet Explorer or Firefox play them?  Have you ever tried to play a .FLV file on your computer?  You probably weren’t too successful in doing so.  .FLV is not a format that Windows Media Player or QuickTime player supports.  You can’t just link to a FLV file on your web page and expect the video to play like you would if it were a WMV or MOV file.  So how is it, that all these web sites have a Flash videos on them?

Whats unique about Flash is that you can create a customized player that embeds in a web site and plays the.  FLV (and some other formats) on the web site.  There are stand along FLV players you can get for your desktop, but most people don’t have those installed because FLV isn’t the type of video file that gets downloaded to a computer.  It’s main purpose in life is play through a web browser.

In the old days (about 5 years ago), the idea of Flash and Video together was silly.  There was no FLV format and you had to embed the video file into a SWF, making the SWF a huge file.  The video wouldn’t play until the whole SWF loaded.  A lot of that changed as the FLV format became widely used.  The FLV would play through a Flash Player and supported progressive downloads (meaning you can watch the video as it downloaded).  Then along came Flash Media server and streaming and now the fun really started!  To read more about the differences between streaming and downloading, click here.

What exactly is a Flash Player?

Using an application like Adobe Flash, you create a small application and compile it into a Shockwave File (SWF),  when the SWF is embedded on the web page, it can accept commands to play media files and FLV is one of those media files.  SWF players are usually very small and download quickly while the web page is loading.  What’s so great about creating SWF players is that they can look and feel how you want.  You can add buttons and functionality.  You can add features like chat, or interactivity, advertising, social media aspects, and easily track video usage.  Think about a little bowling game built into the player, as you are watching a bowling video you can play the game.  All those nifty little animated advertisements you see on web sites, those are mostly Flash SWF files.

How easy is it to make a Flash Player?

Not too easy if you don’t know what you’re doing.  But there are some simple, and cost effective ways to add Flash Video to your site.  One of my favorites is the JW Player by LongTail Video.  This player is OpenSource and free to download (for non-commercial uses).  It’s one of the most popular players out there now and rightfully so.  Besides being a fairly easy to use player, it supports all kinds of plug-ins and since it’s OpenSource you can create your plug-ins or skins.

Here are some of my favorite add-on’s to the JW Player:

• Easy Advertising (they bring quality ads right into your video and you get paid)
• Viral Marketing (add embed, link and comments to your videos)
• Related videos (add a list of related videos for the viewer to see)
• Built in Google Analytics (track the behaviour of each video file)
• HD Button (click a button to swtich between HD and SD versions of the the video)
• Accessibility (Add closed captions to your videos)
• Play Lists (Create play lists displaying multiple videos)
• Player Analytics (Track player movements like, start, stop, pause, etc)
• YouSearch (Search for YouTube videos and plays them inside the JW Player)
• Dozens of pre-made skins to change the look and feel of the player

You can see that the JW Player is very flexible.  They have a great support community and will even provide tech support via email for free!

If you’re looking to add Flash Videos to your web site, there is no real reason to make a custom Flash Player.  A good developer would charge you several hundred to thousands of dollars to develop a player.  Instead use a pre-made one.  Of course there will be times when creating your own custom and branded player is essential.  When that time comes, expect to spend some money and time developing it.

In the mean time, try out JW Player or Flow Player as an inexpensive and easy to use alternative.
