VPS and Dedi you have control over shell_exec and you can turn it on or off at your discretion. So you will be able to use ffmpeg if you want to.  But i would read about the security risk of enabling shell_exec first before you do. 

Update: well i think there is another way but still some hosts turn that feature off as well. 

What i mean by that Franz is that most successful business is built locally and then expands.  So for example if your website is a dating service, then you hit every bar, every restaurant, every little diner, every grocery store and hand out your cards. Sponsor a local event, sponsor an event for the boy scouts or cub scouts. Do you know how many single moms and dads are doing the cub scout deal or soccer deal.  The name soccer mom didnt just come out of the blue ya know lol, thats where your market is.  That is how you get growth, local members then build from there. 

this is great I am getting so much information.

Dave you are right about marketing your site.

Questions guys if you are starting a dating site as a example, what advertisement companies you guys are going with. do to the fact Google doesn't like dating, relationship or etc sites? for adsence profits?

Also how do you guys use seo within your site like keywords?

Im in the U.S

O yeah Franz that's great to hear that your shared hosting allows the ffmpeg because as Dave said most shared hosting does not. 

Hi Zack!

For monetizing your website, I recommend to do it directly with your users, there are many plugins in the store which you can get more profits than advertisements with a third party company. And you keep your users inside your website, I think this is the best way to go.

Wow Dave, I didn't know that. I was looking in my back office for where I can place my keywords to help my seo.

Hello senior developer thanks for you input it is much appreciate it. . I was going to monetizing my website by adsence, and cpm ads and etc. Can you recommend any plugins that can aid that's in the store to add in the monetization of my site?

. Also, I am really thinking about developing a dating/social site along with just my local social community any suggestions for plugins for a dating site?

Dave im a little confused, I thought you mention that you understood google no longer even uses key words as part of their algarythum.

Also, Is there a place in the back office to place keywords in?

Example: 

<meta name="description" content="Free Web tutorials">
<meta name="keywords" content="HTML,CSS,XML,JavaScript">

mplayer - too bloody complicated

jwplayer, no go, you have to pay for using it.

flowplayer - no go same deal

And the others i dont trust. 

So really my only other option especially if we want to play flv files is to use flashplayer and swfObject (which is old and not being developed anymore)  but still works.  

If you want to play flv files and you have another solution let me know here ok, if not i will try to do the flash deal.  

Thanks :) 

also remember that ogg-ogv-and webm cannot always play with html5 because they are not always video/webm /ogg or /ogv file types, many of them are application/octet-stream which html5 will reject

Thanks Tammy also good info... I am up to my bald spot in documentation here and every time i think i have the perfect plan, i read a page that says whoopp cant do that :(

ffmpeg is already integrated so no turning back now.   Also i decided that you must have ffmpeg 2.0+ or php5.4+ to save me from having to support legacy commands that are deprecated. 

OK so ill forget about the flash for now, and just have the videojs running.  The other problem is that there is no test for html5, you have to test for a specific feature.  But since most browsers will do mp4 for the non ffmpeg then i guess thats good enough.   Those with ffmpeg have no worries they can do pretty much what they want.
