// 4:2:0 pictures of one size, here decoded from a clip; Egami.Video writes WebM and IVF and plans the frames for you.
using Vp8StreamEncoder encoder = new(pictures[0].Width, pictures[0].Height);
for (int i = 0; i < pictures.Count; i++)
{
    Vp8FramePlan plan = new()
    {
        KeyFrame = i % 30 == 0,     // a key frame a second at 30 frames a second
        RefreshGolden = i % 10 == 0, // and a golden frame to fall back on every tenth
        Quality = 70,
    };
    Vp8EncodedFrame frame = encoder.Encode(pictures[i], plan);
    packets.Add(frame.Data.ToArray()); // a WebM block or an IVF frame; frame.LumaPsnr says how close it came
