[Live-devel] Scheduler Questions

[Jeff Oliver]

Not knowing the nitty gritty of the scheduler used in the streamer 
library, I have a question about a sequence of events as such.

I have modified the library to allow for skipping though the file (i.e. 
Fast Forward).  So...a client issues a PLAY command and the media starts 
to stream.  Each time a RTP packet is created, the file source is read, 
hence the file pointer moves.  The client then sends another PLAY 
command which instructs the server to start fast forwarding.  I kick off 
a delayed task that does a fseek on the file.

The potential issue I have is doing the fseek at the same time as the 
fread.  How does the scheduler work?  Do i have to mutex these 
accesses?  Or is everything still single threaded, so it wouldnt be a 
big deal.

The follow up question is, im targeting this application to a dual Xeon 
system, so if this scheduler is single threaded, is it feasible to 
convert it to a multi-threaded application?  Would it buy me anything if 
I did?
