[Live-devel] Get one frame at an absolute time

Hello Ross,

I want to be able to request one single frame at an absolute time from the
RTSP Client. Is that possible?

In the client I'm sending a play command with the same absStart/absEnd.

Received 227 new bytes of response data.

> RTP-Info: url=rtsp://
> 192.168.1.6:9000/2/playback/track1;seq=21357;rtptime=771222272

In the server end, my own OnDemandServerMediaSubsession implements
seekStreamSource and I pass absStart/absEnd to my own FramedSource.

How should I implement my FramedSource doGetNextFrame so it only sends
frames until the absEnd is reached (in this case only one frame). Is there
any example FramedSource I can use as a template? Is this the correct way
to do this?

Thanks in advance.
