Constructor Detail

H264TrackImpl

public H264TrackImpl(DataSource dataSource,
                     String lang,
                     long timescale,
                     int frametick)
              throws IOException

Creates a new Track object from a raw H264 source (DataSource dataSource1). Whenever the timescale and frametick are set to negative value (e.g. -1) the H264TrackImpl tries to detect the frame rate. Typically values for timescale and frametick are:

• 23.976 FPS: timescale = 24000; frametick = 1001
• 25 FPS: timescale = 25; frametick = 1
• 29.97 FPS: timescale = 30000; frametick = 1001
• 30 FPS: timescale = 30; frametick = 1

Parameters:

dataSource - the source file of the H264 samples

lang - language of the movie (in doubt: use "eng")

timescale - number of time units (ticks) in one second

frametick - number of time units (ticks) that pass while showing exactly one frame

Throws:

IOException - in case of problems whiel reading from the DataSource
