[FFmpeg-devel] APV codec with OpenAPV support

[d.frankiewic]

Hi, 

 

I'm Dariusz from Samsung Electronics, you can know me from last VDD in
Korea, I was presenting APV.

 

I'm glad that Mark created native APV decoder. As you might know we're also
working on APV implementation for FFmpeg. 

Our approach is different from yours but they can exist in FFmpeg in
parallel. We're using external library OpenAPV for encoding and decoding:
https://github.com/AcademySoftwareFoundation/openapv

This OpenAPV implementation will be also used by Google in next Android 16:
https://developer.android.com/about/versions/16/features#apv

In our approach we have implemented: encoding, decoding and mp4 muxing.
Today we will send patches.

 

So I think now it's a good moment to review both implementations and
integrate them in parallel in FFmpeg.

 

What's your opinion about that?

 

Regards,

Dariusz

Hi Dariusz,

The general "policy" is that external libraries are not used if we already
have a native implementation. Unless that native library has capabilities
(e.g encoding in this case) that we don't have.
