I've just made simple YouTube player in SDI using embedded links inside the TWebBrowser component, and managed to create auto play and loop (loop one and loop all) buttons as well as quality changing radio buttons, but they're all based on hyperlink changes, and therefore does not perform a change while video playing, but have to send "Go" command again. I've implemented it with the buttons mentioned above, but it's annoying to restart video when making a change, especially if I just want to set loop somewhere in the middle of the song.
Is there any way of maybe reading current time and set then set link with that time starting, or any other way of solving this, so when pressing the button, the action will be accepted with no refresh, or won't restart the video from beginning?
The default buttons for changing quality within the player itself does exactly that, but can't find a command.
Also, on YouTube there is a button in playlist to loop, as well as randomize, but can't find them either.

I can't find a simple yes/no answer - maybe my inability to ask the right question. I'm probably not seeing the obvious.
https://developers.google.com/youtube/iframe_api_reference
If I set-up the iframe api example as per the linked page, with an appropriate header (e.g. viewport etc.) then when I view the page in Chrome on the desktop, I can click on the video area to play, and pause the video. I do not need to use the play/pause control.
If I view the same site on my Note 4, I can touch the video area to play. But in order to pause, I have to click on the (now tiny) pause control. Touching the video area does nothing.
I know I can programmatically add some other element and initiate a pause via the API ... but I don't think I can add a touch or onclick event to the player ... and the player state change event won't be any good if the player isn't changing state on subsequent touches?
Yes / No (trying to keep within non-vague / discursive guidelines) ... is it possible, without "hacks" to pause the video, on mobile, with a touch to the video area?
I suspect not, as YouTube's own site, on my Note 4, behaves in the same way. I just can't find any discussion/questions about it. I ask the question, as it seems counter-intuitive to reduce the control area on a smaller touch device for pausing. It's annoying to me ... trying to use embedded YouTube in CSS3D where I have a video-wall 2x2 and the controls become tiny. I might have to overlay a transparent control element for touch but just want to check I haven't gone mad.
I'm looking for a way for my users to take a video (defaulting to front facing camera, but with the ability to switch) lasting 2 seconds, display that video immediately and have it loop indefinitely (no controls displayed). Essentially mimicking a 2 second gif. I would like to do this in app so they can see the video before posting, and potentially retake. Any ideas? I've found some functionality here: https://developer.apple.com/library/ios/documentation/MediaPlayer/Reference/MPMoviePlayerController_Class/index.html#//apple_ref/c/tdef/MPMovieControlStyle but it doesn't seem to address the entire problem set.

Using Video
I have built a player app. It has play, stop, pause rewind and ff buttons.
Where would I find 'stock' icons for the buttons? Eg. the same ones used on the YouTube app and apparently all the other 'mainstream' player applications.
Also, when I go from stop to play or pause, there's a white 'flash' that happens behind the button. Is this something I create programatically behind the buttons?
I may be making something difficult out of something easy. I just don't want to create 'custom' versions if there real ones are readily available in the package.
I noticed there's been quite a few views of this page, and wanted to update the limited success I had.
I discovered an excellent website called Glyphish.com which has an incredible selection of artwork.
Hope this helps.
I'm having a small web app, which plays really short sound bits on the click of several buttons. It explicitly targets mobile Safari on iOS (iPad).
After reading here and elsewhere about the several "shortcomings" of HTML5 audio in this context on mobile Safari and trying a few "hacks" and tricks, I'm stuck with a situation where Safari seems simply (for the lack of a better word) broken:
I can play sound A (it takes a long time for it to start — I'm assuming it's downlading [again]?) on the click of button A. After that, clicking on button B will immediately play the sound A again. Same for button C. In some cases it will play a different sound, sometimes even the right one. But mostly sound A. The format in use was .aiff, is now .m4a .
After writing a few tiny versions myself, I decided to go with the Buzz library to handle the sound loading/playing/etc..
Funnily enough, their demo includes a game, which does pretty much exactly what I need and triggers the same faulty behavior. I even ended up in a situation where any audio player in mobile Safari in any tab would play a certain sound out of the Buzz demo game (!).
I was hoping a cache manifest might help overcome Apples preloading limitations and force the app to play the sound right after hitting the button in offline mode. But after confirming that the whole app had been cached, I can't play/hear any sound in offline mode.
Has anyone managed to get something like this to work somehow? (— Having seen how Apple handles certain things, I' don't expect much response, though… )
Update 1:
The example in this answer causes the same effect: How to synthesize audio using HTML5/Javascript on iPad
Update 2:
Updating iOS (and so Safari) seems to resolve the audio bug. The cache manifest doesn't seem to effect audio files, though. These files are just not available at all.
After removing the cache manifest the app works okay, but adding it to the "home screen" and reloading it prevents the audio from playing as well.
I wish I could tell you there's a magic formula to get all your html5 media to work perfectly, but there isn't. Mobile support for HTML5 audio/video is pretty poor right now; much further behind than its desktop predecesors. To make matters worse, each of the different platforms handle it differently and most of them only support it in semi-recent versions.
However, there are some tricks you can employ to get media files to work correctly in mobile Safari. In order to explain them, you'll need to understand some of its shortcomings.
1) You can't load multiple audio / video files
Its been my experience that the browser will only load one file at a time. If you play one file, go and play another, and then come back and it'll just load that file all over again. And, although I didn't try it myself, I don't believe a cache manifest will help you here.
What I had to do is combine all my audio files into one large audio file. Then, depending on which audio track was requested, I'd move the play position to the appropriate starting position and play that track. Then, I'd use a setInterval to examine the playback every few milliseconds to determine if the current play position hit the end of the track. Once it did, I paused it. Pluis, I gave myself a few seconds (2-3) between each track, just in case the phone's CPU was under a lot of load and checked the feed a little too late.
2) You can't auto-play audio / video files
Apple built into their HTML5 media tag technology the limitation that these tracks would only load and play in response to a user click event. That way, developers couldn't auto-play annoying tracks when you went to their websites.
When I was using audio/video tags, I was trying to build a rich media advertisement. So I hooked my audio/tracks loading to the banner click event, when you click a banner and expand the advertisement.
What I'd suggest you should do is have a small lightbox popup come up, asking the user if they want to turn on/off sound. You can attach your load functions to the click event of that popup box, regardless if the user turns the sound on or off.
Personally, I didn't have much luck using the load() function. I'd run that function to load the audio and then click play and it would just load it again. It could have always been that I just didn't do it right, so feel free to prove me wrong and get that working. What did is I told the track to play, so that way it would start loading, and then I'd use a setInterval to see if the current play time incremented just a few milliseconds. Once I noticed that it started to play the track, I'd immediately pause it.
3) Audio/Video tags are only supported in iOS 4.0 and higher
There's no trick to getting around this. Its just the facts.
Here's a few sites that helped when when I was developing with audio/video tags:

Good luck!
I have a video in my iPad app, but I dont want it to be able to go to fullscreen. However I do potentially want the user to be able to navigate to the part of the video that they want to see.
As far as I can tell there are only three options for the controls that you give the user:
None, Embedded, or Fullscreen.
None gives the user no control.
Embedded and Fullscreen basically give the use the same amount of control but just start in different states.
Basically what I want is Embedded with the switch to Fullscreen option taken out.
Anybody know if its possible? Thanks
You can set the controls style to "None", and then add your own custom view to navigate using a UISlider (I've done this in the past).
MPMoviePlayerController adheres to the MPMediaPlayback protocol, so you take the total playback time of the movie, multiply it by the UISlider value (when it changes), and then adjust the movie's playback head position.
You'll also need an NSTimer or KVO to monitor the playback time so it can update the slider UI element in realtime.
