libvlc视频开发遇到了个大问题，求解啊

[l8409]

问题：

客户端上有个打开文件的按钮，响应函数如下：

void CViewLeft::OnMyButtonFileOpen()
{
	CFileDialog fd(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, NULL, NULL);
	
	CString oriPath;
	CMainFrame* pMain = (CMainFrame*)AfxGetApp()->m_pMainWnd;

	if (fd.DoModal() == IDOK){
		if (pMain->m_MediaPlayer != NULL && 
			libvlc_media_player_get_state(pMain->m_MediaPlayer, &pMain->m_media_ex) == libvlc_Playing){
			libvlc_media_player_stop(pMain->m_MediaPlayer, &pMain->m_media_ex);
		}
		pMain->m_strPath = fd.m_ofn.lpstrFile;
		pMain->m_strPath.Format("%s", pMain->OnAnsiToUtf8());

		pMain->OnPlay();
	}
}

第一次打开一个视频文件不会存在问题，可以正常播放，然后再去打开一个文件就会卡死。

OnPlay()函数如下：

void CMainFrame::OnPlay()
{
	char path[100];
	CViewLeft* pLeftv = (CViewLeft*)m_wndSplitter.GetPane(0, 0);

	if (m_strPath.IsEmpty())
		return;
	strcpy(path, m_strPath);

	if (m_pInstance == NULL)
		m_pInstance = libvlc_new(vlc_argc, vlc_argv, &m_media_ex);

	if (!m_isinit_libex){
		libvlc_exception_init(&m_media_ex);
		m_libvlc_drawable = (libvlc_drawable_t) pLeftv->GetDlgItem(IDC_MY_MEDIA_PLAY)->GetSafeHwnd();
		m_isinit_libex = 1;
	}
    m_media = libvlc_media_new(m_pInstance, path, &m_media_ex);
    m_MediaPlayer = libvlc_media_player_new_from_media(m_media, &m_media_ex);
    libvlc_media_player_set_drawable(m_MediaPlayer, m_libvlc_drawable, &m_media_ex);

	libvlc_video_set_spu(m_MediaPlayer, 0, &m_media_ex);
    libvlc_media_player_play(m_MediaPlayer, &m_media_ex);
	libvlc_media_player_set_rate(m_MediaPlayer, 1, &m_media_ex);

	pLeftv->m_btnPlay.SetIcon(IDI_ICON2);
	pLeftv->m_sliderPro.ShowWindow(SW_SHOW);

	m_ls = libvlc_Playing;
}

到底是什么问题，求解啊

怎么没有人应呢，高手快进啊

你得先看看卡在哪里吧，是否需要先将先前的那个关闭？

[123_321_1234567]

OnPlay的18行之前，先将media_player释放掉： if( m_MediaPlayer ) { libvlc_media_player_stop(m_MediaPlayer,ex); libvlc_media_player_release (m_MediaPlayer); m_MediaPlayer = NULL; }

应该是VLC的Stop接口，调用的时候卡死，好像是出现了死锁！

[这歌声无聊可是辉煌]

这个问题解决了吗？

[糊涂*张]

问题解决了吗？ 我也是有时调用Stop接口的时候卡死

你没释放掉现有的资源，释放就行了。 if (m_pvlc_player) { libvlc_media_player_stop(m_pvlc_player); libvlc_media_player_release(m_pvlc_player); m_pvlc_player = nullptr; }
