Method 'add_OnAudioSourceEncodedFrameReady' in type 'SIPSorceryMedia.FFmpeg.FFmpegFileSource' does not have an implementation.

When I'm trying to:

FFmpegFileSource videoSource = new FFmpegFileSource("test.mp4", true, new AudioEncoder());

I'm getting this error:

System.TypeLoadException: Method 'add_OnAudioSourceEncodedFrameReady' in type 'SIPSorceryMedia.FFmpeg.FFmpegFileSource' from assembly 'SIPSorceryMedia.FFmpeg, Version=8.0.10.0, Culture=neutral, PublicKeyToken=null' does not have an implementation.

I've done a lot of tests, my target platform is Ubuntu Server, but I checked it on Windows 11. Also checked in net 8.0 as a target FW, result was the same. VideoTestPatternSource() works well (just a test after dozens of tries). The error is also repeatable in MP4 examples from SipSorcery repo.

OS: Ubuntu 24.04, Windows 11
Platform: ASP.Net, target net 9.0
Ffmepg v.7.0, v.7.1.1
Nuget:

<PackageReference Include="SIPSorcery" Version="8.0.22" />
<PackageReference Include="SIPSorceryMedia.Abstractions" Version="8.0.12" />
<PackageReference Include="SIPSorceryMedia.FFmpeg" Version="8.0.10" />

Downgrading to SipSorcery 6.2.4, obviously, solves the issue, but require to compile old version of ffmpeg, which leads to another problems.
Maybe there is some versions incompatibilities, but I didn't find out, which combination is fine.

@sipsorcery Good day. Is there something you could advice?

@linius that's my fault. The new OnAudioSourceEncodedFrameReady method was added to the abstractions library. I need to push a new version of this FFmpeg package to fix that exception. I will do so pronto.
