Member Function Documentation

void Mist::InOutBase::bufferFinalize ( unsigned long tid )

inherited

Wraps up the buffering of a shared memory data page.

Registers the data page on the track index page as well

Parameters

tid	The trackid of the page to finalize

void Mist::InOutBase::bufferLivePacket ( JSON::Value & packet )

inherited

Buffers a live packet to a page.

Handles both buffering and creation of new pages

Initiates/continues negotiation with the buffer as well

Parameters

packet The packet to buffer

void Mist::InOutBase::bufferLivePacket ( DTSC::Packet & packet )

inherited

Buffers a live packet to a page.

Handles both buffering and creation of new pages

Initiates/continues negotiation with the buffer as well

Parameters

packet The packet to buffer

void Mist::InOutBase::bufferNext ( DTSC::Packet & pack )

inherited

Buffers the next packet on the currently opened page.

Parameters

pack	The packet to buffer

void Mist::InOutBase::bufferNext ( JSON::Value & pack )

inherited

Buffers the next packet on the currently opened page.

Parameters

pack	The packet to buffer

Note: Internally calls bufferNext(DTSC::Packet & pack)

void Mist::InOutBase::bufferRemove	(	unsigned long	tid,
		unsigned long	pageNumber
	)

inherited

Removes a fully buffered page.

Does not do anything if the process is not standalone, in this case the master process will have an overloaded version of this function.

Parameters

tid	The trackid to remove the page from
pageNumber	The number of the page to remove

bool Mist::InOutBase::bufferStart	(	unsigned long	tid,
		unsigned long	pageNumber
	)

inherited

bool Mist::Output::closeOutputFileForRecording ( )

inherited

void Mist::InOutBase::continueNegotiate ( unsigned long tid )

protectedinherited

std::string Mist::Output::getConnectedBinHost ( )

protectedvirtualinherited

Reimplemented in Mist::HTTPOutput.

std::string Mist::Output::getConnectedHost ( )

protectedvirtualinherited

Reimplemented in Mist::HTTPOutput.

unsigned int Mist::Output::getKeyForTime	(	long unsigned int	trackId,
		long long	timeStamp
	)

protectedinherited

long unsigned int Mist::Output::getMainSelectedTrack ( )

inherited

Returns the ID of the main selected track, or 0 if no tracks are selected.

The main track is the first video track, if any, and otherwise the first other track.

void Mist::OutRaw::init ( Util::Config * cfg )

static

void Mist::Output::initialize ( )

virtualinherited

Trigger:: The "CONN_PLAY" trigger is stream-specific, and is ran when an active connection first opens a stream.

Its payload is:

streamname
connected client host
output handler name
request URL (if any)

The "USER_NEW" trigger is stream-specific, and is ran when a new user first opens a stream. Segmented protcols are unduplicated over the duration of the statistics log (~10 minutes), true streaming protocols (RTMP, RTSP) are not deduplicated as no duplication ever takes place. Its payload is:

streamname
connected client host
User agent checksum (CRC32 of User-agent string)
output handler name
request URL (if any)

Reimplemented in Mist::OutDashMP4.

void Mist::InOutBase::initiateMeta ( )

inherited

Opens a shared memory page for the stream metadata.

Assumes myMeta contains the metadata to write.

static bool Mist::Output::listenMode ( )

inlinestaticinherited

void Mist::Output::onFail ( )

virtualinherited

Called when stream initialization has failed.

The standard implementation will set isInitialized to false and close the client connection, thus causing the process to exit cleanly.

Reimplemented in Mist::HTTPOutput, and Mist::OutHTTP.

virtual bool Mist::Output::onFinish ( )

inlinevirtualinherited

Reimplemented in Mist::OutProgressiveOGG, and Mist::OutJSON.

virtual void Mist::Output::onRecord ( )

inlinevirtualinherited

Reimplemented in Mist::HTTPOutput.

void Mist::Output::onRequest ( )

virtualinherited

Reimplemented in Mist::OutRTSP, Mist::OutRTMP, Mist::HTTPOutput, and Mist::OutProgressiveOGG.

bool Mist::Output::openOutputFileForRecording ( )

inherited

void Mist::Output::prepareNext ( )

virtualinherited

void Mist::Output::reconnect ( )

inherited

Connects or reconnects to the stream.

Assumes streamName class member has been set already. Will start input if not currently active, calls onFail() if this does not succeed. After assuring stream is online, clears nProxy.metaPages, then sets nProxy.metaPages[0], statsPage and nProxy.userClient to (hopefully) valid handles. Finally, calls updateMeta()

bool Mist::Output::recording ( )

protectedinherited

void Mist::Output::requestHandler ( )

virtualinherited

Reimplemented in Mist::HTTPOutput, and Mist::OutPush.

int Mist::Output::run ( )

inherited

Trigger:: The "CONN_OPEN" trigger is stream-specific, and is ran when a connection is made or passed to a new handler.

Its payload is:

streamname
connected client host
output handler name
request URL (if any)

The "CONN_CLOSE" trigger is stream-specific, and is ran when a connection closes. Its payload is:

streamname
connected client host
output handler name
request URL (if any)

Todo:: generate payload

void Mist::Output::seek ( unsigned long long pos )

inherited

void Mist::Output::selectDefaultTracks ( )

inherited

void Mist::OutRaw::sendHeader ( )

inherited

void Mist::Output::stats ( )

inherited

void Mist::Output::stop ( )

inherited

Clears the buffer, sets parseData to false, and generally makes not very much happen at all.

void Mist::Output::updateMeta ( )

inherited
