php curl vs browser

Yes.

The SID refers to a session, and is only valid temporarily, and for a given browser/ip address combo. In this case your SID isn't valid for that request. SID's are not transferable. G2 is designed to be queried by browsers which maintain session via the cookie (which is the normal way for the SID to be returned) and not by things like curl. You can't copy a SID from a browser url and expect it to work anywhere else.

@suprsidr: does ImageBlock/curl work for images that require a login/password to view? The core.DowloadView method will also work, if images are not protected.

I actually have a file that was for streaming flv based on xmoov if you are interested.

FlashYourWeb and Your Gallery with The E2 XML Media Player for Gallery2

Thanks suprsidr I'll have a look into it.
How do I use it?

Yes you are right with that.

Maybe suprsidrs approach is the better one.
I'll try to add seeking capability.

greets
littlejam

Ok, seeking is now possible.
However there is no security at this point so there is some more coding that have to be done.
I'm crawling through the g2-api for the right calls. Hints are welcome ;-)

The script works with JWPlayer (v. 4.5).
It must be placed into the modules/flashvideo/lib-directory of G2.
The flashvars should look somehow like this...

there would be some code inside this if the spamfilter would accept it 

type=http
streamer=url to mediaStreamer.php
file=g2_itemId.g2_serialNumber.g2_GALLERYSID

It is important that the file-parameter consists of more than the g2_itemId (more precisely: more than only numbers) otherwise the JWPlayer throws an error which can only be avoided by changing and recompiling the player itself.
I added g2_serialNumber and g2_GALLERYSID divided by dots; at the moment these are of no other purpose than preventing JWPlayer from failing.

Thanks a lot suprsidr.
The script works now as expected :-D

It only works good and simple with .flv-files.
Even if you encode with AME you have to insert the metadata with another tool.
I used flvtool2.exe

flvtool2.exe -U C:\myclip.flv

This adds the metadata.
After that you can upload the file into g2 and seek to any point in the clip.
