sorry for the convoluted and subjective question, but multimedia is totally out of my area of expertize.
I know there are several alternatives to embed video on a page. There is HTML 5 <video> tag, there is video/ogg content type which seems nobody uses, there is Flash SWF embedding or Flash FLV progressive, I think Silverlight has something and finally there is external hosting.
My needs are for a commercial site video tour, it has to be fairly good quality. Good hosting is around USD $100/mo (I looked at viddler.com, the ones 37signals use), over my budget. Is there a good, commercial, hosting at under USD $20/mo ?
So I'm considering the alternatives. I believe my best bet is on SWF, is a tested technology, supported by plenty of platforms. Besides I'll need to use their charting components anyway later down the road. What tool do I need? Standard Flex Builder, Professional Flex Builder or I can use the free Flex SDK?
What other alternatives are there?
There are already many Flash applets that will play video in any browser that has the Flash plugin (as new as possible, hopefully). For example, Flowplayer is pretty much ready to use out of the box. All you have to do is embed it on your website and point it towards whatever video file you want to show.
I assume you're not hosting the next YouTube, in which case a quality webhost with generous or unlimited bandwidth caps would be enough. (I have used Site5 for $5/month before and haven't been banned, at least :p).
As for quality, generic FLV uses an older codec that's not so great. Newest flash player can use the excellent H.264 codec (what YouTube uses for HQ and HD video) in MP4 container (take a look at this tutorial). Of course, the higher the bit rate, the better the quality, but the slower the video loads.
For playing videos that you control Flash is probably your best bet. The JW player is pretty good and fairly cheap to purchase for commercial sites. It's very easy to setup too.
You just need to make sure that you're serving files that Flash can play.

Good luck!
You could make a youtube account, upload your videos there and then embed them on your site. It is free to use, widely supported, and you can reach a bigger audience that way.

In short, I want to record presentation audio, create time markers for that audio in a database, and then provide marker-navigation of that audio content from a web page. What technology (e.g. HTML5 Audio, RTMP) can support this?
My requirements in more detail:
quickly navigate to server-side marked points in server-stored audio, from the browser.
avoid any proprietary client-side software, such as Silverlight; although due to penetration Flash is acceptable, and future-looking standards like HTML5 media are acceptable, provided it ships with the latest browsers.
prefer to leave the 30-50 minute audio files un-split rather than pre-splitting on the selected markers; so that the markers can be seamlessly changed later.
like to keep licensing cost minimal; although single-purchase licensed server-side technologies are fine.
prefer to do most of this from IIS, where I have most experience. however, a parallel streaming server such as Adobe with Windows APIs is acceptable.
Here are my best guesses on a solution so-far:
the presentations will be compressed and stored in mp3 files (but really, any advice on an easily seekable format for speech recording is welcome).
the client will play a unicast stream rather than download file chunks (although TBR, below, challenges this assumption)
HTML5 is not ready, so flash will be required at the client
IIS Media Services is no-go as it requires Silverlight for seekable audio
The leading products in this space, such as Adobe Media Server 5, are probably large kits with their focus on video media. I can probably find a more focused tool like Icecast to reliably do what I need.
OK, I'll bite. I went and looked for how people actually address this, and it's how I said it is in my comment.
Setting HTML5 audio position (it's so close it almost makes this question a dupe)
I've also found this nice blog post from 2009 that describes the further technical possibilities and options. The latter part revolves around advanced video use cases and Ogg, but the first part should apply just fine to <audio>.

After several years working with commercial and custom Flash video players, such as Flowplayer and jwplayer, I decided to open my work to html5. I like the idea of having a Flash impersonation of html5, so I tried medialements.js, video.js and jplayer. None of them are production ready and they all fail to meet my goal, which is playing a video on a webpage, desktop and mobile, live and vod.
Does anyone has a suggestion for a working web video player, apart from the commercial ones?
TIA

I can get to what you are saying. Videojs is a leader in HTML5 video and considered state of the art by many though I think it falls short on some aspects especially for iOS/Android and Live streaming. Here is a list that compares some common actors of the market.
After much time playing with the different players available I decided to build my own HTML5 video jQuery based player. I learned so much while doing so and if you are planning on re-using it for your projects it will be much faster to tweak your own player rather than trying to build something up on a player someone else built. Now doing so requires you like JavaScript and are happy to deal with the cross browser testing. This article can give you a place to start. Digging in further would require you take on board the W3C spec.
Live streaming in HTML5 video is limited today: HLS for iOS and Android > 4.1 and coming in fast MPEG DASH (it has a JS lib for live and on demand here). If you want to cover a large audience for live video streaming you still need to consider flash.
Coursera has these interactive questions in the middle of their video lecture
how could I go about implementing this myself,
or better yet, does this feature exist for public use somewhere?
Furthermore, I'm trying to decide which HTML5 video player / platform to invest in and the key criteria would be feature-rich (so as to not reinvent the wheel / spend lots of time implementing video player features) as well as highly customizable (for those custom needs).
I.e. which player should I use to get the quiz up,
but in the near future I would also need to add the speed feature that Coursera has
I need Closed Captions support
and would like to overlay slides every now and then
plus all the expected features of switching between different source resolutions (360p, 720p etc), it should work in IE, Firefox, Chrome, Safari, Android and iOS native browsers etc
Candidates
In terms of customizability and feature-set, SublimeVideo seems to come on top, but I don't know when they will support subtitles.
Haven't researched Flowplayer much, would that be better for my purposes?
Jwplayer is good for all the standard features, and includes subtitle support, but I haven't really seen any plug-ins, aesthetic skinning aside, deep customization does not really seem to be their focus / strength?
Or videojs
Or something else yet ?
Flowplayer and Jwplayer are amazing players and you could do what you want, but in the free version you can't remove their branding. I try to stick to opensource projects you you don't worry about licenses.
I've done something similar as you need with Mediaelementjs. It supports all you need at the moment, and they will support the variable speed at some point on the future as announced in their website. However it has been like that for more than a year now since I started watching, so probably your "near future" is before their "coming soon".
I think your best free option will be Videojs. They also support all you need. For the variable speed there is this plugin.
Basically you set up a listener in the timeupdate event, and when it reaches the point that you need, you attach the quiz html to overlay the video area.
I have used flowplayer extensively. I'm just now starting to dive more into their new HTML5 version. The licensing for flowplayer is reasonable. It does have a plugin for doing subtitles and the cue point functionality works great. I also like that they have the Flash version that works well for fallback and I still use it for rtmp streaming.
I have built a video presenter with synchronized slides using the flash version which I'll be changing over to have an HTML5 version. I use it to produce speaker videos with Powerpoint presentations. Sometimes we have surveys (live) so I have also been planning to build in the option for a survey slide.
You can take a look at what I have built as an example here (it has some lose ends). Example synchronized video slide presentation (I have no affiliation with Flowplayer. WebVideoDesk, branded on the linked page, is a service I am planning to launch someday.)
I notice that there are many libraries out there for playing HTML5 audio, but ain't the whole idea of HTML5 audio that we don't need a library for this to work properly?
If I don't need Flash fallback, but a simple solution for streaming music (my own) that can also play each track after each other, do I then need a library like jPlayer or Soundmanager2?
I know I need different audio formats, but that's not a problem as I won't have many tracks online.
The "whole idea" of HTML5 audio is that end users and web page authors shouldn't need to rely on a browser plugin to play audio - the functionality should be included in the browser, and controllable directly from standardised HTML/JavaScript.
I haven't used an HTML5 audio library, but looking at the jPlayer and Soundmanager2 home pages, it looks like the main functionality they offer is fallbacks for browsers that don't support HTML5 audio.
I suspect they might also have some built-in custom UI for playing audio though, in case you don't like the native audio controls that browsers provide.
You could use straight-up HTML5, but you'd soon realize that has a whole host of problems.
Library's like jPlayer (which is great by the way) account for many common issues like browser support, optimization and fall-backs etc.
If you want to code all that yourself you can, but a popular library will be leaps ahead and it's the wise choice to take.
The truth is, HTML5 offers very powerful features, but its support is thin at this current moment in time. It's all to make your life easier!
HTML-5 audio actually encompasses two distinct factions at this point. One is the audio tag and the other is the Web Audio API. The former is a quick mechanism for playing an embedding audio files, the latter is a way to play,process and manipulate audio in a low-latency manner acceptable for game development and more professional environments where features like reverb effects,filters,"3D" sound and other characteristics are needed. But to answer your question, the only real reason to use a library for the HTML 5 audio tag is (in my opinion) for backward compatibility between browsers as well as ease of use for things like multi-shot file triggering and event handling.
I want so serve some videos on my site. They are available as .MP4 files gotten from a FlipShare camera.
Now I tried converting them to WMV (which succeeded, but when embedded in html in a <object id='mediaPlayer' width='320' height='285' classid='CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95' etc' tag, users have to install an addon and the user experience of 10 Windows Media Players on the site isn't just so good.)
So then I looked at youtube and wondered how they do it, but I can't figure out what format they convert the video to.
So my question is: What format do I have to convert my video to, to show it in a player which does not need to be installed in the users browser. What tool do i need and what is the html code to embed such a video?
As you can see: starting from scratch.
PS: I often hear: This or that file extension is just a container, there can be anything inside. If you're using this in your answer, can you explain this to me, because I never understood this. For me a .cs is a c# file and a .doc a Word file, and not 'a container'.
This isn't an easy question. The basic answer is that you need to use a format that the user's computer already supports. There is no one answer to this question. YouTube encodes videos as MP4 and embeds them in the page with a Flash-based movie player, and Flash is pretty widely supported, but you'll notice that Flash isn't available on a lot of mobile platforms — so anybody using an iPhone is shut out if you go the Flash route.
HTML5 introduces the video tag, which is meant to solve this problem once and for all, but there's still a hiccup even there — most HTML5-enabled browsers support h.264-encoded video, but Mozilla supports Ogg Theora instead. YouTube is currently experimenting with a <video>-based player, so this does seem like the future.
I believe the current best practice to support the most people possible is to encode as h.264, try to serve as a <video> element, and have a Flash-based player as a fallback if that doesn't work (which can play the same h.264 file).
I'd say the most popular solution at the moment - utilized by YouTube and other major video portals - is H.264 encoded Flash-based Video. Flash can play Video since... I think Version 8 or 9, and has since gained significant market share.
My personal favourite Flash player is LongTail Player, but it isn't free for commercial use.
Here's a SO question with a list of Flash based players including open source ones.
Flash won't play on iPhone and iPad, though.
If you want to support computers with Flash Player 9 (I've seen some around, but I don't have any hard numbers) you will need to encode FLV files (which use a codec named Sorenson I think).
The upcoming alternative is HTML 5 Video but suport for that in browsers is nowhere near a major market share.
This question requires a re-answer now that it's no longer 2010 and HTML5 videos (as utilized by most video hosting sites) and chunk-based videos (sent as responses to periodic XHR requests - as utilized by Youtube) are the norm. While there is no best way to add video to your site, Flash is definitely nowhere close to even being good as of the time of writing of this answer.
The simple un-researched answer is: Just use a video tag and it'll work out!
This is simple and intuitive, and should work fine in many of your use-cases.
The researched answer is: Unfortunately, upload the video on Youtube and embed it on your site.
The pros and cons of embedding on Youtube over just having a video tag:
The pros:
Allows you to offer your video in a multitude of qualities.
Very bandwidth efficient. Youtube is bandwidth efficient for your users since it reencodes videos, and is also bandwidth efficient for you since you'll no longer be serving your videos off your own hosting.
Offers features like closed captions, automatic subs, playing at multiple speeds, full screen player, etc.
The cons:
It's a very heavily monetized service, chances are they'll want to put ads on your video if any of its content isn't 100% originally yours.
It has very strict laws/terms and conditions that you need to adhere to, at least in my opinion.
It tracks your users. If your application requires privacy and you can't rely on your users to protect themselves, then Youtube isn't ideal.
Other alternatives that mix the pros and cons of those two options are:
Using a Javascript video library to get HTML5 video along with some of the pros of using youtube, but none of its cons.
Using FFMPEG on the server side, for bandwidth issues.
Using some CDN that supports video to deliver the video, for reliability and bandwidth issues. My current favorites are ones that rely on service workers and the bittorent protocol, to stream from users to each other, but whether that suits you or not depends on your application.
Using AWS storage services to store the video, and AWS gateway/CDN services to serve it, which might be a great solution cost-wise and efficiency-wise if you don't want youtube but don't want to store videos on whatever infrastructure is serving your website.
Sources of this answer: Personal experience. As much as I didn't want to answer from experience, this question really needed a new answer! Feel free to edit it with something more concrete.
Converting your video MPEG-4 with H.264 will get you 97% coverage on current browsers across desktop and mobile, although some Android devices don't support hardware acceleration for this format. To address that you could also serve WebM with VP9 codec.
