I get the same error when calling VideoSource.StartVideo(). My code replicates this example from SipSorcery: https://github.com/sipsorcery-org/SIPSorceryMedia.FFmpeg/blob/master/test/FFmpegFileAndDevicesTest/Program.cs

Tried it with having VideoSource file at different locations on my local computer but all give the same System.AccessViolationException: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

EDIT: was able to fix this issue by also including:

AudioSource.OnAudioSourceEncodedSample += AudioSource_OnAudioSourceEncodedSample;
RTCPeer.OnAudioFormatsNegotiated += (audioFormats) =>
{
    AudioSource.SetAudioSourceFormat(audioFormats.First());
};

This was necessary even without calling AudioSource.StartAudio()
