[Live-devel] Current playing file stats

[Dex]

Thanks Ross,

Currently I am streaming without the use of 
MediaSession/MediaSubsession, check the below pseudo-code for how I am 
streaming the files:

Groupsock rtpGroupsock
Groupsock rtcpGroupsock
SimpleRTPSink *videoSink =  SimpleRTPSink::createNew
RTCPInstance* rtcp = RTCPInstance::createNew
ByteStreamFileSource* fileSource
videoSource = MPEG2TransportStreamFramer::createNew
videoSink->startPlaying

So my question would be where would I fit the MediaSubsession in the 
above context?

Thanks,

So for example if I could get/retrieve the last read byte index, or the elapsed  time relative to the currently playing file, or anything else that helps in the said regard, then I could use this information to update the GUI accordingly.
