527748826c
- Re-visited the race condition fix in the cDvbPlayer (thanks again to Andreas Schultz). - Changed the VFAT handling to allow users who normally use it but have forgotten to set it when compiling a new version of VDR to at least see their recordings made with VFAT enabled (thanks to Christian Rienecker). - Added some missing teletext PIDs (thanks to Joerg Riechardt). - Fixed PID handling for cReceiver. - Added a missing #include to ringbuffer.c (thanks to Martin Hammerschmid). - Now using CC, CFLAGS, CXX and CXXFLAGS in Makefile. - Changed the cDevice class to allow plugins to implement their own devices (see PLUGINS.html for details).
