I have subtitles prepared in .ssa (SubStation Alpha) format and they work fine in VLC player. I would like to play this video from my local machine within reveal.js presentation with subtitles displayed. How?
I see this: https://github.com/spiegeleixxl/html5-ass-subtitles but it is dated and from the description, limited.
Am I limited to .vvt format as per here http://www.html5rocks.com/en/tutorials/track/basics/?
Would be good to know if there is an established workflow for this.
Thank you.

Here are the only 2 options I found:

I want to display ads with VAST ad tag and with a HTML5 player. I'm currently trying to use videoJS with Vast Ads Plugin and I'm noticing I can't get the videoJS player to work without having a video content (video element with a src attribute for the video content).
Does anyone know a simple way to use a video player for just ads from VAST, and without video content? Google IMA3 SDK allows that, but I'm now looking for video plugins to cover IE use case (which Google IMA3 SDK does not cover).
Thank you!
There is a dirty way to do this. You can get the ad video url from the plugin that already parsed by it. Then just paste as src to video tag.
If the player you are using support only running pre-roll, that's obviously the best choice. Since that's likely not the case, I would recommend creating a small 1 second long black video MP4 and setting it as the content, with all video controls disabled. This was the lowest friction solution for me, as I didn't need to ask the player anything special of the player. The pre-roll plays, and the user briefly sees black at the end, which may not really be noticed.
I'm setting up video.js and would like to use a single video encoding format (H264) in order to save space (it would save over 50% in my case). video.js falls back to a flash player when HTML5 video isn't possible, but I'd like it to also fall back when H264 support isn't present too (in Firefox, for example). Is there some way to make this happen?
You could try detecting support for that format directly if you needed to - although I agree, it should fallback to Flash automatically.
http://diveintohtml5.info/detect.html#video-formats gives an example of detecting support for h264
You don't need to do anything. That is what will happen.
It works here, for example. Do you have a URL where it's not working for you?
I am planning to build a system to broadcast public events (trials, meetings, conferences).
A key request will be the insertion of live subtitles to the A/V stream.
The subtitles will be "live" since they will be produced by an operator while the event will happen.
I suppose the HTML5 "track" element is not yet implemented by any of the major browsers, but: can I expect to eventually use it for live subtitles? Will I be able to inject the subtitle to the page while the stream is playing?
Please Look at the following links. Looking at the link i am having to believe it should be possible as they are using Js to show subtitles
http://www.storiesinflight.com/js_videosub/
http://cuepoint.org/
You may also consider http://mozillapopcorn.org/ which is to show content on timing of the video. So technically u can use this with ajax to show/stream subtitles
There are HTML5 video JS libs that support subtitles (eg: VideoJS supports the .srt format, there are several easily Google-able others), however to the best of my knowledge none of them support streaming subtitles.
I think you may have to build your own solution for this. If I were to do it, I'd probably try doing something with Socket.IO's broadcast functionality that can push data out to all connected clients at once, and have your client-side JS listen for new subtitle events and render them on screen as they come in. You can use plain ol' CSS to overlay the text over the HTML5 video.
I have few links to .mp4 video files like
file1.mp4
file2.mp4
file3.mp4
I need to play them all in player as one file. Actually not necessarily "as one" file, the player must act like it's one file. My best guess is to create custom controls and playback area for MPMoviePlayerController and divide the playback by time slices.
For instance
file1.mp4 file2.mp4 file3.mp4
-----------|------------|------------
Is this a good approach? Can this be done anyhow easier?
Also, the server, from which I'll get the videos is not customizable and I can't convert videos to MPEG-2 and stream them via .m3u8 files.
Thanks in advance
I guess you can use AVQueuePlayer. It supports multi-item playback. Haven't tried that myself (I used AVPlayer for single-item playback). I believe that AVQueuePlayer usage should reduce your overall efforts. ( You will still be responsible for drawing playback controls )
I sticked up to the scenario I described in the question and was able to create the player component.
I want to make simple project which play flash video file from online.
I've searched some articles and read carefully.
But I can't understand, how to play flash video files on iPad by Code.
So I need help from you.
Please.
Simply put, without being jailbroken, No you cannot.
The closest thing to being able to view flash in iOS is Frash, and I am not even sure if it is actively being developed or supported any more.
You can always check out the open source project for Frash. by Comex.
All IOS devices don´t support Flash player, but is be possible to use a Javascript or HTML5 player for video.
No, iWhatever's currently do not and to the best of my surfing knowledge, have no intention of supporting flash format due to some argument between apple and adobe.
At the end of the day, the Flash video format is a container for a movie that’s been compressed by some codec. If you can get to the source file, you know the format of the container, you know the codec that was used to encode the video, and you know how to write code to convert that into audio streams and video frames, then yes, you can play Flash videos on the iPad.
So, to recap:
Get the Flash video file.
Get to the encoded video data in the Flash file.
Decode the video and convert it, either into raw audio and video or to another format that the iPad can play.
Play the result of #3.
Needless to say, this is quite the endeavor. It’s better to download the movies to your desktop and convert them there before loading them into your application.
Yes you can! The question is whether or not you can play the video itself not whether or not ipads support flash player.
the answer is this.. new versions of "flash video" have a f4v file extension. These videos are basically a h.264 mp4 files. You "may" be able to play it in an ipad simply by renaming it to .mp4
If that doesn't work then use a utility like Miro to convert your "flash video" to a format that your ipad will accept. http://www.mirovideoconverter.com/
