Constructor & Destructor Documentation

cRecorder::cRecorder (  const char *    FileName, int    Ca, int    Priority, int    VPid, int    APid1, int    APid2, int    DPid1, int    DPid2 )

Creates a new recorder that requires conditional access Ca, has the given Priority and will record the given PIDs into the file FileName. Definition at line 22 of file recorder.c. References active, esyslog, fileName, fileSize, index, isyslog, lastDiskSpaceCheck, MakeDirs(), NO_PICTURE, cFileName::Open(), pictureType, recordFile, remux, ringBuffer, and SpinUpDisk().

cRecorder::~cRecorder (    )  [virtual]

Definition at line 57 of file recorder.c. References cReceiver::Detach(), fileName, index, remux, and ringBuffer.

Member Function Documentation

void cRecorder::Action (  void    )  [protected, virtual]

Implements cThread. Definition at line 109 of file recorder.c. References active, dsyslog, fileName, fileSize, cRingBufferLinear::Get(), I_FRAME, index, LOG_ERROR_STR, MINVIDEODATA, cFileName::Name(), NextFile(), NO_PICTURE, cFileName::Number(), pictureType, cRemux::Process(), remux, ringBuffer, safe_write(), uchar, and cIndexFile::Write().

void cRecorder::Activate (  bool    On )  [protected, virtual]

This function is called just before the cReceiver gets attached to (On == true) or detached from (On == false) a cDevice. It can be used to do things like starting/stopping a thread. It is guaranteed that Receive() will not be called before Activate(true). Reimplemented from cReceiver. Definition at line 66 of file recorder.c. References active, cThread::Cancel(), recordFile, and cThread::Start().

bool cRecorder::NextFile (  void    )  [private]

Definition at line 91 of file recorder.c. References fileName, fileSize, I_FRAME, MEGABYTE, cFileName::NextFile(), pictureType, recordFile, and RunningLowOnDiskSpace(). Referenced by Action().

void cRecorder::Receive (  uchar *    Data, int    Length )  [protected, virtual]

This function is called from the cDevice we are attached to, and delivers one TS packet from the set of PIDs the cReceiver has requested. The data packet must be accepted immediately, and the call must return as soon as possible, without any unnecessary delay. Each TS packet will be delivered only ONCE, so the cReceiver must make sure that it will be able to buffer the data if necessary. Implements cReceiver. Definition at line 102 of file recorder.c. References active, esyslog, cRingBufferLinear::Put(), and ringBuffer.

bool cRecorder::RunningLowOnDiskSpace (  void    )  [private]

Definition at line 78 of file recorder.c. References DISKCHECKINTERVAL, dsyslog, fileName, FreeDiskSpaceMB(), lastDiskSpaceCheck, MINFREEDISKSPACE, and cFileName::Name(). Referenced by NextFile().
