The crash happens in LAV Splitter itself. To be specific in the code that handles the Vorbis audio. The extradata is empty and that isn't handled properly.

File also plays with old gabest splitter.

But then how do you explain that after remuxing to MKV the LAV Splitter handles the Vorbis audio tracks just fine?

Sigh. Because this bug is not triggered in that situation. There is probably also bug in FFmpeg's Ogg parsing code. Your comments are not helpful.

Here is another "not helpful" comment...

If LAV Splitter and FFmpeg based source filters like FFMS2 and LSMASH all are buggy when it comes to opening OGG files then my conclusion is that the OGG format is obsolete or broken enough so that nobody cares to support it. Remux to MKV... (MP4 also works fine.)

It is possible that the audio track uses the even more ancient Vorbis ACM codec which is not fully compatible to the output of e.g. oggenc2.

File plays ok with LAV 0.68.1-4, and got broken by FFmpeg update.
