Handling crashes when using libVLC to decode a stream

Postby hvz » 18 Sep 2015 12:00

I've made a program that uses libVLC to receive and decode audio streams.

Sometimes - depending on the stream format - libVLC crashes, usually when for example some packages have been losts. This only happens for certain codecs.

My problem is that - because libVLC is calling my code, and not the other way around - I don't know how I can catch the exception that occurs so I can handle it gracefully instead of having it kill my application. Is there a solution for this?

As you know, the only way to protect your app from actual crashes is to run separate processes.

That's the only way to be 100% safe, but my experience is that you can catch almost any crash and at least shut down gracefully (or restart) and write some logging using try/catch. So that's what I would like to do here as well.

How and how well to catch run-time exceptions is platform/OS dependent, and really out of scope of a LibVLC forum.

Well, sure. But the thing is: If I could call VLC instead of having VLC call me, it would work (at least under Windows). The way things are now I'm going to have to search for a different solution; only a very small percentage of people who use my software use the VLC integration, but the majority of bug reports that I'm getting are in fact VLC bugs.

You're not making much sense. LibVLC being a library, obviously your program calls LibVLC, not the other way around.
