Media Player 6.4

Media Player 6.4

1, 怎么获得 01:50 / 03:20 这个播放时间?

2, OnError怎么捕获错误码?

3, OpenState, PlayState的值哪有文档? MSDN上找不到具体值(可能是我没找到)

1.long total = (long)m_player.GetDuration();
CString time = GetStringTime(total);
CString CProgramer_EditView::GetStringTime(long sec)
{
int h = 0;
int m = 0;
int s = 0;

if(sec >= 3600)
{
h = sec / 3600;
m = (sec - 3600*h)/60;
s = (sec - 3600*h - 60*m);
}else
{
m = sec/60;
s = sec - 60*m;
}
CString str;
str.Format("%d:%d:%d",h,m,s);
return str;

}

2.TRY{
if(leftvoice == LEFT_SD)
m_vidoHold.m_media.SetBalance(LEFT_SD);

来自window media sdk,但是我的实践中数值好像不对,0的状态好像没有,其他状态数值减一!
也就是Stopped状态其实是0,Paused状态是1 ... 以此类推

wwwllg(wwwllg) :


unsigned long total = (unsigned long)m_pMedia->GetDuration();

GetDuration是总时长， Position是当前时段
