You will notice after the video starts that if you try to jump to another position in the video it will reset and start over. So that is the problem.
As you can see the source is external. This uses JW PLayer, but I have tried with other players to.
I have tried with other hosts and video formats and its the same issue.
Can somebody help me with this cause I'm stuck?
I don't think the source media file being on another server/domain has anything to do with your problem.
You have a progressive download video here, and seeks just fine to the point of download. Yes, it does restart from the beginning if you try and seek past the last downloaded mark, but that is to be expected. (How could a client seek into data it doesn't even have yet?)
You have two choices:
Tweak the player so that it never attempts to seek beyond the last downloaded point. If you are only going to have clips this small that this solution seems fine.
Put the clip behind a streaming or psedu streaming server. (More appropriate for longer clips.)
Streaming: red5, Wowza, FMS, etc
Pseudo streaming: apache/lighttpd/etc with mod_h264_streaming + some client side logic denote the position to stream to

I'm developing an application, where it is necessary that a video is exactly at the playback position, where it should be if there were no lack of data, even if there is such.
eg. video.currentTime == timeSinceTheVideoWasStarted
The tolerance is about 0.1s and it is also possible to increase or decrease the playback speed a little bit to match the time.
All the media data is cached in a ObjectURL, but the decoding may be slow, because the application is very computation intensive.
I thought about setting the correct playback time at the playing event, but when data is present again and the currentTime is updated this will case the next lack of data.
I'm using the video element as a video texture source in WebGL as described here.
The fixed points are that the video is downloaded from a local server (for example http://localhost:8000/assets/foo.mp4) and displayed on WebGL. Your Soulutions may include different video decodings than the native <video>.
To reproduce it: Do something CPU intensive and play a video - it won't be smooth. (As you would expect)
I hope you can help me.
EDIT:
The main thing I worry about is the situation, I aleady experienced many times while nornaly working, likely windows itself is doing some sync disk IO, which causes everything to wait, even the mouse cursor...
I'll try it out to compensate small time differences (< 1s) by the playback speed
I'm using dash.js reference player and I'm trying to do frame-wise steps through a video by simply pausing and calling seek() with the appropriate timestamps on each step.
But there is an annoying delay after each step, because the player seems to keep reloading the same segment again and again.
The screenshot shows the requests:
The first step caused segment 19 to be (re-)loaded. After some idle time, the next 3 segments were loaded, too. Then I did 5 steps in a row, each of which resulted in a request for segment 19.
Is there any way to make dash.js cache a segment while I'm stepping through its content?
This would be an interesting read for your issue, even though it seems Ahmed Basil had answered well. DASH Monitoring
I would recommend using an SDN-based script with P4/OpenFlow to run your player with the segmented video, the reference player automatically records all the segments that are loaded into the player and send them to the client.
If you use a tool like Wireshark, you will be able to see all the segments used in the experimental run. To answer your question, the player usually reloads the same segment when there is an interruption (network or physical) wise.
It could be trying to change the segment root folder due to the player's preferences and resolution used. It will always reload a segment when that condition appears or it's trying to change a resolution due to an interruption. To conclude, yes there is a way to make dash.js cache a segment while it's playing a file. Simply make the Wireshark application monitor your player, this way you will see all the segments used, shown in the image here.
I'm trying to write a nodejs website for streaming html5 video (webm, mp4). But don't know how to know when user finished viewing video. That mean, we need a start point (the point that user start to view video), and an end point(the point that user finished to view video). And we can know how many percents that they are viewed the video.
The video are located at our server.
The video HTML element (which is a subclass of MediaElement) has currentTime and duration properties that you can look at in JavaScript, and also a bunch of events you can listen for, like onplay, onplaying, onpause, ontimeupdate, etc.

I'm building a video player where each scene is filmed from multiple angles. All videos are hosted on YouTube. I'd like to allow the user to be able to switch between angles seamlessly during playback.
To facilitate this, I need a way to load videos from YouTube without playing them. That way I can load alternate angles in the background while one angle is playing. When the user switches angle, the new angle should be at least partially loaded and ready to play immediately.
Unfortunately, I can't find a way to load a video without playing it.
The loadVideoById method autoplays the video as soon as the request to load the video has returned so that won't work.
Is this possible?
There's no way to cue up a video and force it to pre-buffer.
You can load (as opposed to cue) a video and then immediately pause it, and it may or may not pre-buffer, but that's dependent on a number of factors and is outside your control as someone using the API.
There is a program at enounce.com that it will increase the play speed of a video in a browser. I think that 95% of videos on the internet run on flash therefore this tool can be useful. I am wondering how that program was created. Maybe they modify the html source in the browser? perhaps it looks for the swf video playing on your browser and it injects some JavaScript on that html element to increase the speed. I been researching on Google and I think it is possible to alter the playback speed of a video with JavaScript. If it is not modifying the html page then it will be nice to at least know how this can be achieved. Also if a video plays on your browser it has to be saved somewhere in your computer I believe. That's why you can seek back and forth once the video finished downloading. why is it that it is almost impossible to find it and the only way of getting that video will be by capturing the packages with a package sniffer? anyways that is not my question I am just really curious on how that program achieves doing what it does. it speeds up everything even Pandora songs.
MySpeed seems to intercept the media stream coming from the server into the Flash player that sits in your browser. It changes the speed on the fly, and sends the result to the Flash player.
PS: If you need to control the playing speed of your own videos I recommend looking into the VLC Browser Plug-in, or the QuickTime player, which also has very good speed control features (from Javascript). Or you could use the HTML5 <video> tag.
Afaik, Flash-based players like Longtail/JWPlayer and Nonverbla don't have very good support for this.
