◆ onReadData()

int io.agora.mediaplayer.IMediaPlayerCustomDataProvider.onReadData ( ByteBuffer  buffer,
int  bufferSize 
)

The player requests to read the data callback, you need to fill the specified length of data into the buffer.

Parameters
bufthe buffer pointer that you need to fill data.
buf_sizethe bufferSize need to fill of the buffer pointer.
Returns
you need return offset value if succeed. return 0 if failed.

◆ onSeek()

long io.agora.mediaplayer.IMediaPlayerCustomDataProvider.onSeek ( long  offset,
int  whence 
)

The Player seek event callback, you need to operate the corresponding stream seek operation, You can refer to the definition of lseek() at https://man7.org/linux/man-pages/man2/lseek.2.html.

Parameters
offsetthe value of seek offset.
whencethe postion of start seeking, the directive whence as follows: 0 - SEEK_SET : The file offset is set to offset bytes. 1 - SEEK_CUR : The file offset is set to its current location plus offset bytes. 2 - SEEK_END : The file offset is set to the size of the file plus offset bytes. 65536 - AVSEEK_SIZE : Optional. Passing this as the "whence" parameter to a seek function causes it to return the filesize without seeking anywhere.
Returns
whence == 65536, return filesize if you need. whence >= 0 && whence < 3 , return offset value if succeed. return -1 if failed.
