[pjsip] wav_player.c calls EOF callback twice

[Ryan Littrell]

I'm using a local build sipek sdk and pjsip trunks. I noticed in the log the
wav player calls the EOF callback twice. In the second call, the free(args)
fails. Any thoughts?

Log:

EOF Code:

static PJ_DEF(pj_status_t) on_wavplayerEof_callback(pjmedia_port*
media_port, void* args)
{
       PJ_LOG(3,(THIS_FILE, "on_wavplayerEof_callback, media_port: %d",
media_port));
       pj_status_t status;
       wavplayerEof_Data* WavePlayerData = ((wavplayerEof_Data*) args);

       // Read info from args
       pjsua_call_id call_id = WavePlayerData->callId;
       pjsua_player_id player_id = WavePlayerData->playerId;

       //Destroy the Wav Player
       //status = pjsua_player_destroy(player_id);   // ! Problem if
Destroying Here : cash at the end of callback, for most of wavs files

       // Free the memory allocated for the args
       free(args);
       PJ_LOG(3,(THIS_FILE, "End of Wav File, media_port: %d", media_port));

       // Invoke the Callback for C# managed code
       if (cb_wavplayerEnded != 0)
               (*cb_wavplayerEnded)(call_id, player_id);

       if (status == PJ_SUCCESS)    // Player correctly Destroyed
               return -1;                      // Don't return PJ_SUCCESS,
to prevent crash when returning from callback after Player Destruction

       return PJ_SUCCESS;             // Else, return PJ_SUCCESS

}      //// -> goes back to the function wich has invoke the callback :
fill_buffer() in pjmedia\src\pjmedia\wav_player.c
       /////   CRASH HERE WITH MOST OF WAV FILES, if player has been
destroyed above ////
