[vlc-devel] VLC deadlock at libvlc_media_player_stop(Even in latest release 1.1.0)

[Parveen Jain]

I am running this in Linux.
code for play and stop media is as:
Here I am creating inst only once in this function.createLibVLCInst(){ const char * const vlc_args[] = {               "-I", "dummy", /* Don't use any interface */               "--ignore-config" /* Don't use VLC's config */                };//	libvlc_exception_init (&ex);
	inst = libvlc_new (sizeof(vlc_args) / sizeof(vlc_args[0]), vlc_args);}
int PlayVideo(fileToPlay,char *ipAddr,int videoRtpPort,int videoRtcpPort,int audioRtpPort,int audioRtcpPort,void *userData) {    	char vlcOption[500];    memset(vlcOption,0,500);
	DP_LOG(TRACE_DEBUG,DP_INFO,"[videoStream::PlayVideo]->Entering");    //const char * file ="h263_alaw.mov";  
	libvlc_instance_t * inst = sSipVideoMgr.getInstance();	 	m = libvlc_media_new_path (inst, fileToPlay.c_str());
	mp = libvlc_media_player_new_from_media (m);
    // Create an event manager for the player for handling e.g. time change events    m_pEvtManager=libvlc_media_player_event_manager(mp);
	SetEventHandler(handleVideoEventsCB,userData);	sprintf(vlcOption,"sout=#transcode{acodec=alaw,channels=1,samplerate=8000}:rtp{dst=%s,port-audio=%d,port-video=%d}",ipAddr,audioRtpPort,videoRtpPort);
	libvlc_media_add_option(m,vlcOption);
	libvlc_media_release (m);			libvlc_media_player_play (mp);
	DP_LOG(TRACE_DEBUG,DP_INFO,"[videoStream::PlayVideo]->Exiting");
  	return 0; // only to prevent compiler warning}
int videoStream::stopVideo(){	/* Stop playing */	libvlc_media_player_stop (mp);
	/* Free the media_player */	libvlc_media_player_release (mp);}
Running this flow for almost 30 "H263 video" calls per second; and It freezes after every 3-4 hours of testing.
Let me know if you need any more info for reproducing it.
