i am using postgresql, but that won't work with stock-mythtv.
i would'nt be surprised if the ReadStringList errors are caused by
mythtv relying on usleep doing a context-switch. the "backend" is the
mythtv-backend.
patch mythcontext.h to undefine usleep:
int mythsleep2(unsigned int microsec,char *file,int line);
#undef usleep
#define usleep(x) mythsleep2(x,__FILE__,__LINE__)
and mythcontext.cpp:
int mythsleep2(unsigned int microsec, char *file, int line)
{
fprintf(stderr,"sleep: %s : %d\n", file,line);
/* sync(); */
QWaitCondition qw_sleep;
/* pthread_yield(); geen RTC voor normale pthreads!!! */
qw_sleep.wait(microsec / 1000 + 1);
}
or any other yield you can think of.
you might try different treading style as well.
regards,
usleep
