Method Details

start

public boolean start(MediaIO io,
 int new_width,
 int new_height,
 int new_chs,
 int new_freq,
 boolean seekable)

Starts decoder.

Parameters:

io - = MediaIO interface

new_width - = change video width during decoding (-1 = no change)

new_height - = change video height during decoding (-1 = no change)

new_chs - = change audio channels during decoding (-1 = no change)

new_freq - = change audio frequency during decoding (-1 = no change)

seekable - = do you need to seek position during playback?

startFile

public boolean startFile(String file,
 String format,
 int new_width,
 int new_height,
 int new_chs,
 int new_freq)

Starts decoder.

Parameters:

file - = file to write to.

format - = format of file (see MediaCoder.AV_FORMAT_...) (NULL = auto detect)

new_width - = change video width during decoding (-1 = no change)

new_height - = change video height during decoding (-1 = no change)
