Why the switch to encode2? All previous versions were using the
send/receive API, and seeing SVT also uses a decoupled input/output API,
it was certainly the most adequate option.
Were you running into some issue? A quick look at v12 shows you were
using ff_alloc_packet2(), which afaik you shouldn't have. It's meant for
the encode2() API only, where user provided buffers are allowed, and it
alone does not ensure the packet will be reference counted, which is
required for the send/receive API.
