I use live555 lib under windows.
I write code to get MPEG file duration:
TaskScheduler* scheduler = BasicTaskScheduler::createNew();
BasicUsageEnvironment* env = BasicUsageEnvironment::createNew(*scheduler);
MPEG1or2FileServerDemux* demux =
MPEG1or2FileServerDemux::createNew(*env, inputFileName, False);
if(demux)
return double(demux->fileDuration());
In ealier versions of live555 all works fine, but in newest version
process terminates abnormally on line
MPEG1or2FileServerDemux::createNew()
I check source code and found bug in BasicTaskScheduler.cpp
In this file lines from line 73
#if defined(__WIN32__) || defined(_WIN32)
int err = WSAGetLastError();
// For some unknown reason, select() in Windoze sometimes fails with
WSAEINVAL if
// it was called with no entries set in "readSet". If this happens,
ignore it:
if (err == WSAEINVAL && readSet.fd_count == 0) {
err = 0; // BUG at this line
// To stop this from happening again, create a dummy readable socket:
int dummySocketNum = socket(AF_INET, SOCK_DGRAM, 0);
FD_SET((unsigned)dummySocketNum, &fReadSet);
}
if (err != EINTR) {
#else
must look like this
#if defined(__WIN32__) || defined(_WIN32)
int err = WSAGetLastError();
// For some unknown reason, select() in Windoze sometimes fails with
WSAEINVAL if
// it was called with no entries set in "readSet". If this happens,
ignore it:
if (err == WSAEINVAL && readSet.fd_count == 0) {
err = EINTR; // err SHOULD be EINTR for the further comparision
// To stop this from happening again, create a dummy readable socket:
int dummySocketNum = socket(AF_INET, SOCK_DGRAM, 0);
FD_SET((unsigned)dummySocketNum, &fReadSet);
}
if (err != EINTR) {
#else
Is this right?
