Can someone help me with HTTP Dynamic Streaming?
I have been googling the crap out of this. I am a video producer for a Non-Profit and in the next couple of weeks we are launching an online training, half of which requires watching multiple different video clips – for this particular training around 50 deferent online videos. I’m a bit experienced with encoding video for the web (FLV, H.264) but would love to know more about HTTP Dynamic Streaming. As of now we just use a progressive download type of playing. We recently hired a web dev and knows servers a bit but didn’t seem like he knew anything about HTTP Dynamic Streaming – said maybe we should search the internet for an auto detecting flash player? Anyways, is this something that I should be looking into for our organization if we do a lot of online video? If we purchased Flash Media Server would this be all we need? Is there like a Dummies book on this subject? Thanks for any help

Thanks Saeroner for showing interest in HDS. This is definetely a new era technology.
As I said in my earlier post, I would like you to encourage to download the developer version of the FMS. In case of HDS, this version restricts you to 30 minutes of viewing time.
So for example, once you have installed the FMS, go to <installation-dir>/samples/videoPlayer/videoplayer.html. Open the player and yourself evaluate the HDS vs progressive HTTP
For progressive HTTP, you may play http://localhost/vod/sample1_150kbps.f4v
For HDS, you may play http://localhost/hds-vod/sample1_150kbps.f4v
Though, video quality may not be different, but you may find buffering happening in case of progressive, while HDS will be instant delivery.
Other than this, the main point that I feel you might be really interested as online training company is that you may not like to freely distribute the content to the subscribers.. In case you can win the trust of training content creater that his/her content will be completely protected and can be viewed only to those having rights to view it, it will encourage content creater to host their content on your solutions. Today when premium content creation is so expensive, one would not like it to be get pirated by progressive downloads..
FMS within HDS provides you facility to completely protect your content. Though that's a bigger step..
Other than this, in today's world.. Desktops are not the only medium to watch the content.. Tablets, mobiles are replacing the desktops for day to day purposes like video watching, social site browsing etc... Though tablets and devices may not be attached to high bandwidth network all the time, but HDS provides you flexibility to host streams with different bit-rates and do an adaptive bit rate switching... In such case, progressive download may not at all give you that seamless experience and would require hell lot of time for video to first completely download and start..
You only need client side management in flash for the HDS. HDS requires OSMF player that you either download or build yourself as per your customisation.

Can someone help me with an iCloud problem when I take a picture with my iPhone 4s it some of the times go to my ipad2 but mostly it doesn't can anyone help me out
I'm assuming you have Photo Stream set up of both devices. However, it seems many users are experiencing the same as you - my take is that streaming photos is not foolproof yet.

I have iOS 7. When I go to the itunes store on my ipod touch it gives me a blank screen with nothing on it. I restarted my ipod touch and it didn't work. Can someone help me with this?
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Go to Settings>iTunes and App stores and sign out and sign back in
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device. -

Hi, can someone help me with my External HDD??? Please
Hi, Can someone help me with my Extenal HDD???
PleaseAfter you have all of the files from the External HDD you want to save, to format the HDD:
Open Launchpad
Open Utilities
Open Disk Utility
Select Hard Drive to format (the external HDD)
If you want to change partition size or number select Partition Table
Select number of partitions and adjust sizes if more than one
Name the partitions
Select the format from the pop-up menu (use Mac OS Extended (Journaled))
If it is not already selected, select GUID Partition Table
Click OK
Click Apply
And it should do the formatting for you.
Note: giving a name may come after the format selection, I sometimes get that out of order but it will lead you through the process. -
HI everybody i want to ask if you come me in help, i want to draw paths but when i use stroke options with pen or brush settings i loose quality when i zoom in , can someone help me with pen settings???
The work path is a vector object, and infinitely scalable, but when you stroke it, Photoshop lays pixels on a layer that follow the path. These pixels are raster based and can not be scaled without loosing quality. You do have options. If you want to make the raster layer bigger, transform the work path and stroke it again. Or work at a higher resolution in the first place.
Incidentally, you can't stroke a Path with the Pen, because it is a Vector based tool, and stroking is a raster based function. -

I have followed the instructions to update Flash Player, the Installation Fails at about 90%, it says that there is an Application running (Safari) and it says to close all the apps. and start again ... but I already close all the Applications ... none is running ... can someone help me with this issue ??? Thanks ...
Dear Dominic
Brilliant reply. Simple English. Simple to follow instructions. And it worked immediately, first time.
Why couldn't the Apple and Adobe corporations get their programming right first time? We spend billions of UK pounds and US dollars with them. They reply with incompetent programming such as this, and arrogance to their customers in issuing faulty systems without doing the most rudimentary checks.
Anyway, I certainly shan't be buying another Apple as this is the most unreliable, most incomprehensible, most illogical and downright thoughtless shoddy piece of computer kit which I have ever owned. And all of it is rubbish ~ emails disappear, photos can't be organised properly, spreadsheets don't work, Pages is laborious… the list goes on and on...
But thanks to you Dominic, I have been able to load Adoble Flashj… maybe eyou should get a job at Apple, and set them all on the right course to how to work simply and correctly with customers.
Thanks again,
David -

My iphone 4S Black 16 GB with IOS 7.0.4 turns off randomly in low battery less than 15% and also when I am taking pictures from my front camera in low battery of 30%. This is happening very often. Can someone help here with advise? The phone is slightly more than 2 years bought from singapore I live in India
Either your battery is failing or your battery gauge needs to be recalibrated. Start by recalibrating:
When it shuts off charge for just a minute or two, then restart (hold HOME and SLEEP until an Apple logo appears). Deliberately run the battery down until the phone shuts off at 1%. If it shuts off above 1% repeat the above until you get to 1%. Then charge for 4 hours with the wall charger without using the phone. This process will recalibrate the battery gauge.
To prevent this from happening again about once a month run the battery all the way down to 1%, then continue until the phone shuts off. Apple recommends this in their battery help article, but they don't say why you should do it. The have some hokum about "keeping the electrons moving." Honestly! The iPad battery tip gives the correct reason.
If this does not resolve the problem you most likely need a new battery. If you are near an Apple store take the phone in and they can test the battery for you.
