Member Function Documentation

◆ AutoSelectTrack()

int DecoderBase::AutoSelectTrack ( uint  Type)
protectedvirtual

Select best track.

In case there's only one track available, always choose it.

If there is a user selected track we try to find it.

If we can't find the user selected track we try to picked according to the ISO639Language[0..] settings.

In case there are no ISOLanguage[0..] settings, or no preferred language is found, the first found track stream is chosen

Returns
track if a track was selected, -1 otherwise

Reimplemented in AvFormatDecoder.

protected

Definition at line 1169 of file decoderbase.cpp.

◆ BestTrack()

int DecoderBase::BestTrack ( uint  Type,
bool  forcedPreferred,
int  preferredLanguage = 0 
)
protected

Determine the best track according to weights.

Select the best track. Primary attribute is to favor or disfavor a forced track. Secondary attribute is language preference, in order of most preferred to least preferred language. Third attribute is track order, preferring the earliesttrack.

Whether to favor or disfavor forced is controlled by the second parameter.

A preferredlanguage can be specified as third parameter, which will override the user's preferrence list.

This function must not be called without taking m_trackLock

Returns
the highest weighted track, or -1 if none.

◆ DoFastForward()

bool DecoderBase::DoFastForward ( long long  desiredFrame,
bool  discardFrames = true 
)
virtual

Skips ahead or rewinds to desiredFrame.

If discardFrames is true and cached frames are released and playback continues at the desiredFrame, if it is not any interviening frames between the last frame already in the buffer and the desiredFrame are released, but none of the frames decoded at the time this is called are released.

Reimplemented in AvFormatDecoder.

◆ DoFastForwardSeek()

void DecoderBase::DoFastForwardSeek ( long long  desiredFrame,
bool &  needflush 
)
protectedvirtual

Seeks to the keyframe just before the desiredFrame if exact seeks is enabled, or the frame just after it if exact seeks is not enabled.

The seek is not made if framesPlayed is greater than the keyframe this would jump too. This means that frame-by-frame seeking after a keyframe must be done elsewhere.

If the seek is made the needflush parameter is set.

Parameters
desiredFrameframe we are attempting to seek to.
needflushset to true if a seek is made.

◆ SyncPositionMap()

bool DecoderBase::SyncPositionMap ( void  )
virtual

Updates the position map used for skipping frames.

There are different sources for position maps, depending on where we are getting the stream from.

positionmap sources: live tv:

  1. remote encoder
  2. stream parsing decide keyframedist based on samples from remote encoder

watching recording:

  1. initial fill from db
  2. incremental from remote encoder, until it finishes recording
  3. then db again (which should be the final time)
  4. stream parsing decide keyframedist based on which table in db

watching prerecorded:

  1. initial fill from db is all that's needed
