ffmpeg 6.0 bindings

[iamcarbon]

It looks like we've got a new build of ffmpeg this week. This is a request, when time allows, to port the new bindings! As usual, many thanks for maintaining this project.

We may also want to consider bringing the minimum .NET framework target from net45 -> net462 to match Microsoft's support policy and target net6.0 directly (instead of .NETStandard 2.0/2.1).

If .NETFramework is ever dropped, this also opens up the possibility of replacing [DllImport] with [LibraryImport] in the future.

Okay, I'll dig into.

I also vote for ffmpeg 6.0 bindings but I don't agree to dropping .NET Standard 2.0 as it is still widely used for libraries. For example legacy .NET Core 3.1 and .NET 5.0 projects cannot reference net6.0 target. Change from net45 -> net462 is ok but nuget package already has net472 target.

If .NETFramework is ever dropped, this also opens up the possibility of replacing [DllImport] with [LibraryImport] in the future.

I guess [LibraryImport] is available only with net7.0+ . This can be supported with #if NET7_0_OR_GREATER statements without dropping .NETFramework.

So my suggestion is we have these targets:

net45/net462 -> can be dropped (or stay if people vote)
net472 -> should stay if net45/net462 is dropped, can be dropped only if netstandard2.0 stays
netstandard2.0 -> should stay (can be referenced from net472, net3.1 and net 5.0)
netstandard2.1 -> should stay (can be referenced from net3.1, net 5.0, net6.0)
net7.0 -> can be added for cutting edge features like [LibraryImport]

If we would like minimal targets in nuget package, I think these targets will be sufficient:

netstandard2.0 -> current .NET Framework users (net472, net48) and legacy .NET Core users (net2.1, net 2.2)
netstandard2.1 -> current .NET users (net3.0, net3.1, net 5.0, net6.0)
net7.0 -> cutting edge .NET users

Note that netstandard2.0 can be referenced from down to net461 (some support DLLs may be copied to bin by VS) but net472 supports it natively.

I'll drop only outdated frameworks - they mostly used by China users - might be fragmentation in packages but I'll try to avoid

While we wait for V6 bindings, what's involved in releasing a 5.1.2 build?

[Ruslan-B]

Releasing makes no sense as there is no change in API , but I'll create packages as some bug fixes have to be done.

Great! Thankyou. Is it a big step to ffmpeg6?

Appears to be working - testing now - I'll publish packages tomorrow if no issues found.

[adamhewitt627]

Any update on this?

[Ruslan-B]

I published packages, basics are working fine

[adamhewitt627]

Thank you very much, I look forward to getting into it now.
