[Live-devel] compilation error

[Kohler, Jeffrey]

That's a pretty standard C++ compilation error.

 

The base class you're deriving from is declaring some functions but
isn't defining any implementations for them.  In order for you to derive
from that class, you need to provide your own implementations of those
functions.

 

The lines right below "due to following members" should tell you what
functions you need to implement.

 

Looking at OnDemandSeverMediaSubsession.hh it looks like the two
functions you need are:

            createNewStreamSource()  and createNewRTPSink

Hi,

I tried to make a class which inherit livemedia
OnDemandServerMediaSubsession class.

I define a static function createNew which call the constructor, like in
a lot of LiveMedia classes.

When I try to compile, the following errors occur :

 

error C2259: 'MJPEGOnDemandServerMediaSubsession' : cannot instantiate
abstract class due to following members:

 

I made a lot of test, but this error remains.

Has anybody ever had this kind of error ?

 

Thanks,

 

Guillaume
