MPEG-DASH VOD scrubbing

Hi,

We’ve noticed that it takes close to 20 seconds for playback to resume when scrubbing ahead on the sample file using the MPEG-DASH sample player. Playing the same sample file using other protocols does not exhibit the behavior. Is this a known issue with MPEG-DASH? We’re running Wowza 4.0.6.

Thanks

Hi,

You may want to try adjusting the MPEG-DASH Packetizer parameters to see if this will reduce any latency.

There’s a How-to guide here.

Thanks Daren. The guide refers to live content. I was asking about VOD content. To reiterate, I’m trying to play the sample.mp4 file in the contents folder of the wowza installation.

Thanks Daren. You’re right, that works much better!

Hi,

That article does have a VOD adjustment further down the page, but upon reflection isn’t the issue.

Looks like it’s player related.

If you use this latest js player here, you’ll find it performs MUCH better when scrubbing through.

Our Manager UI test player is a bit behind some of the latest.
