libvlc 1.1.0 threads deadlock

[sinha_aditya]

While executing multiple media player in a single file, starting and stopping them, it is observed that after a while while stopping media player the thread hangs in pthread_join. I assume it expects some thread to terminate. On further exploration it is observed that there is one more thread (inputThread) which is waiting for a mutex which is not currently being held by any other thread. On debugging I found that the thread having the lock is terminated, as mutex owner is not present in the process. Following is the stack trace of the threads

[Rémi Denis-Courmont]

I cannot see any code path that could possibly "leak" rtp.c's lock_sink in the way you describe in either 1.1-bugfix or master VLC trees.

I think that i ran into the same problem here: viewtopic.php?f=32&t=78972

you can observer there are 8 threads waiting on vlc_joinj similarly 8 threads are hanging on mutex when calling rtp_del_sink. I think there is correlation between these threads.

Following is the test program for the same
#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
#include <vlc/vlc.h>
#include <string.h>
#include <unistd.h>

void handleVideoEventsCB(const libvlc_event_t* pEvt, void* pUserData);
void* vlcPlayer(void*);
libvlc_instance_t * inst;
int main(int argc, char** argv)
{
int numThreads=20;
if(argc >= 2)
{
numThreads=atoi(argv[1]);
}
const char * const vlc_args[] = {
"-I", "dummy", /* Don't use any interface */
"--ignore-config" /* Don't use VLC's config */
};

inst = libvlc_new (sizeof(vlc_args) / sizeof(vlc_args[0]), vlc_args);

pthread_t threadArray[numThreads];
for(int i=0;i<numThreads;i++)
{
pthread_create(&threadArray,NULL,vlcPlayer,NULL);
}
pause();
}

void* vlcPlayer(void*)
{
while(1)
{
libvlc_media_player_t *mp;
libvlc_media_t *m;
libvlc_event_manager_t* m_pEvtManager;
char vlcOption[500];
memset(vlcOption,0,500);


m = libvlc_media_new_path (inst, "test.mp4");

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);

libvlc_event_attach(m_pEvtManager,libvlc_MediaPlayerEndReached,handleVideoEventsCB,mp);
sprintf(vlcOption,"sout=#transcode{acodec=alaw,channels=1,samplerate=8000}:rtp{dst=%s,port-audio=%d,port-video=%d}",
"10.0.5.31",7060,7062);

libvlc_media_add_option(m,vlcOption);

libvlc_media_release (m);

printf("\nStartting Playing Media");
libvlc_media_player_play (mp);
sleep(5);
/* Stop playing */
printf("\nStopiing Playing Media");
libvlc_media_player_stop (mp);

/* Free the media_player */
libvlc_media_player_release (mp);
}
}


void handleVideoEventsCB(const libvlc_event_t* pEvt, void* pUserData)
{
printf("\nvlc Event=====");
}

It is as I said... That code does not dead lock here. (I had to remove the while(1) otherwise it never ends though)

[sinha_aditya]

Using the debugger I observe that thread which is waiting on pthread_join is waiting for thread to terminate which is waiting on mutex within rtp_del_sink () function.
The purpose of the while(1) loop is to create multiple vlc player instances over the time. So its a kind of stress testing. The idea is to have around some n instances of vlc_player at any instant.
The threads hangs after around 1-2 hour of stress testing. In single run I never observed that thread hangs.
So I am looking into way to debug it.
You can simulate the above condition by executing the sample code.
Hope to get some idea about the condition.

[Rémi Denis-Courmont]

There are not too many threads that can lock the lock_sink you're complaining about. In fact, there are only two of them: the one that calls pthread_join(), and the ThreadSend() thread. Personally, I cannot reproduce the bug and I cannot find any place where it could happen, so I will assume that this is a problem with your pthread implementation, until proven wrong.

[sinha_aditya]

while starting the application libvlc emits following error messages
LibVLC has detected an unusable buggy GNU/libc version.
Please update to version 2.8 or newer

Is this the cause of the problem ?

[Rémi Denis-Courmont]

Could be.

[sinha_aditya]

after linking vlc with glibc.2.11.2 following error is generated bu test program

[0x8216fd4] main stream output error: stream chain failed for `transcode{acodec=alaw,channels=1,samplerate=8000}:rtp{dst=10.0.5.31,port-audio=7060,port-video=7062}'
[0x822a984] main input error: cannot start stream output instance, aborting

I am currently using gcc-4.5 with glibc-2.11.2

Looking for some resolution from your end

[Rémi Denis-Courmont]

It is likely a codec problem, but without verbose logs only an omniscient being would know.
