seek accuracy?

[frankensound]

Hi,

I'm developing a website/flash application that can record and later synchronise two flv netstreams. Up until now we've been using fms but am just testing both wowza and red5.

In both cases I'm finding ns.seek(number) is not very accurate compared to fms. I'm guessing it is seeking only to keyframes and not to the accuracy of milliseconds within the stream as fms can. Can anyone confirm this is the case?

The website is for musicians so millisecond accuracy is very important.

thanks muchly.

Frank,

Add this Property setting to the /conf/[app-name]/Application.xml /Streams /Properties list:

<Property>
	<Name>seekTarget</Name>
	<Value>enhanced</Value>
</Property>

Richard,

I have a similar problem. We use the server to review short (less than 30 second) spots and when we scrub anywhere in the first 10 seconds it always starts over. I have used the above property to no avail. The streams are from .mov files in mp4 format.

Any ideas?

Scott,

Make sure that property is the correct Properties list (/Streams /Properties).

Higher fps and/or lower gop might help.

FPS is already at 30. don't have access to change gop. But can enable settings for streaming as "max packet sizes" and "max packet duration". We will set the duration for 100 milliseconds, not sure if it will make a difference.

And yes, I did have the setting under the Streams area of the file. that part does get a bit confusing.

I used enhanced, what is the most precise setting within that property?

thanks for the help,

Scott

The most precise setting is "enhanced"
