Well, it's weird that none of the almost 2000 people on our LIVE555 developers' mailing list has complained about this.  So I don't know why you're the only person who is having a problem with this code.  But I agree that the code doesn't look kosher, and should be improved.

Does it make your compiler happier if you replace the line:

      long streamChannelIdLong = (long)key;


      u_int64_t streamChannelIdLong = (u_int64_t)key;
