What did you do?
Start playing the video, click into the timeline to seek to a different spot of the video.

What did you expect to happen?
The player to seek and continue play.

What actually happened?
The player seeked to the spot, the video changes to that frame, but doesnt continue playing. Also: player is frozen now, not possible to press play again. Console output ends with "calling switch_()" and then "switch_", just like if it would work. It also fires all the "timechanged" and "seek" events, just doesnt ever play again.

Seeking does work if I seek by using the html5 api. It also works if I press the "-30s" Button of the Edge HTML5 video controls. Seeking also works perfectly in Chrome and Firefox.

I encoded the video like this:

ffmpeg -i "$source_absolute" -c:v libx264 -preset ultrafast -tune fastdecode -g 100 -crf 28 -vsync passthrough -c:a aac -strict -2 output.mp4

And then created the dash files like this:
MP4Box -dash 4000 -frag 4000 -rap -bs-switching no -segment-name segment output.mp4

Does anyone have an Idea wat the Problem is?

edit:

Also, the video and audio data is muxed into one file.

If I put seperate segments for audio and video into the mpd file, it works perfectly with the dash-if dash.js.

@mchanton, we can't reproduce your issue from the MPD in your gist without also having access to the segments. Can you post them somewhere for us to try?

Here's a 2 minute test clip with segments and mpd:
https://drive.google.com/file/d/0B5FcVrgW0GCXdHJIdmlMZXpldjg/view?usp=sharing

Created with this ffmpeg call:

ffmpeg -ss 3600 -loglevel error -i video.mp4 -t 120 -c:v libx264 -preset ultrafast -tune fastdecode -g 100 -crf 28 -vsync passthrough -c:a aac -strict -2 output.mp4

With the content you sent via drive, I am unable to reproduce on Edge 15. Here's a demo:

What Edge version do you have? (Check navigator.userAgent and look for Edge/XX.)

Thanks for checking my video!

I tested your demo page on Edge and it worked for me as well. Then I used the dom inspector of Edge and realized that that Demo page isn't using the html5 native video controls, it uses own controls inside the dom. This means the video is getting seeked with the javascript api and not the native controls. My error only happens with native controls. Seeking with the javascript api works for me too.

Is using own custom video controls (seekbar, play button etc.) the way to go?

[joeyparrish]

We intend to support the native controls, as well. You shouldn't always have to implement your own (although it does give you much more UI and UX freedom to do so).

Let us try again with native controls.

[joeyparrish]

I can reproduce on Edge with native controls, and I'm well on the way to a fix.

[joeyparrish]

The fix has been cherry-picked for v2.1.7.

Thanks a lot for fixing it!
