SeekPreroll and CodecDelay also written by ffmpeg (with the same values) and
required for Opus.

Where do you see that? We don't write BlockVirtual
But we write real BlockGroups with Blocks, while ffmpeg writes SimpleBlocks
(except for the last). We should do that too as it causes overhead to not use
SimpleBlocks.
