I checked the code mentioned, and it works as expected.
But now I have a question... is possible to do the same (stream only
N mins of file, or make an infinite loop) from the server side?
Well, if you want to only stream N minutes of a file - without the
client asking you to do this - then the best/right way to do this
would simply be to create a new file in advance, by editing the
original file, and then asking your clients to stream from the new
file instead.
As for streaming a single file over and over again, in an infinite
loop (again, without the client asking you to do this): You could do
this, but you'd need to write a new "FramedFilter" subclass that sits
in front of your "ByteStreamFileSource" class (and presents the
illusion of delivering a single, unbroken stream to the downstream
object (a "MPEG2TransportStreamFramer")). You'd also need to write a
new "OnDemandServerMediaSubsession" class (replacing the existing
"MPEG2TransportFileServerMediaSubsession" class) that uses your new
"FramedFilter" subclass.
Also, because you're streaming a Transport Stream file, you'd need to
make sure that the 'discontinuity flag' is set at the start of the
file, so that PCR values (and thus presentation times) don't get
messed up when the server loops back to the start of the file.
None of this really has anything to do with 'trick play' (in
particular, you won't be creating index files at all), because - from
the client's point of view - you're not doing anything other than
playing a simple stream.
