Crash playing CDDA Audio

[MattWheatley101]

I have some simple code that that tries to play CD audio from a CD, It works around 50% of the time. The other times it crashes with a critical error in the heap with the call stack pointing to a free in Win32DebugOutputMsg. I am using 3.0.20 of libvlc. Here is the code I am using to play the CD.

Code: Select all

libvlc_instance_t * pVLCInstance = m_libvlc_new(0, NULL); if (pVLCInstance) { libvlc_media_t * pVLCMedia = m_libvlc_media_new_location(pVLCInstance, "cdda:///e:/"); if (pVLCMedia) { m_libvlc_media_parse_with_options(pVLCMedia, libvlc_media_fetch_network, 10000); libvlc_media_list_t * pVLCMediaList = m_libvlc_media_list_new(pVLCInstance); if (pVLCMediaList) { m_libvlc_media_list_add_media(pVLCMediaList, pVLCMedia); libvlc_media_list_player_t *pVLCMediaListPlayer = m_libvlc_media_list_player_new(pVLCInstance); if (pVLCMediaListPlayer) { m_libvlc_media_list_player_set_media_list(pVLCMediaListPlayer, pVLCMediaList); int iCount = m_libvlc_media_list_count(pVLCMediaList); m_libvlc_media_list_player_play(pVLCMediaListPlayer); Sleep(20000); m_libvlc_media_list_player_stop(pVLCMediaListPlayer); m_libvlc_media_list_player_release(pVLCMediaListPlayer); pVLCMediaListPlayer = NULL; } m_libvlc_media_list_release(pVLCMediaList); pVLCMediaList = NULL; } m_libvlc_media_release(pVLCMedia); pVLCMedia = NULL; } m_libvlc_release(pVLCInstance); } }

Here is a picture of the callstack.

Any ideas, The Crash appears to happen after the call to "m_libvlc_media_list_player_play" and the debug output is as follows

Code: Select all

It looks like something is corrupting the heap and at a random free it crashes. Is there something wrong with my calling code?

Thanks
