Crash playing CDDA Audio
Posted: 22 Apr 2024 10:55
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.
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
It looks like something is corrupting the heap and at a random free it crashes. Is there something wrong with my calling code?
Thanks
