This is one reason why I have the `seekback` option disabled by default

32k is too small i agree

I can see the reasoning here, but as "small enough" here means 32K, I don't
think this would be worth doing on a per-muxer basis. Maybe if we had a more
general way to tell the muxer about segment boundaries, or if segment.c
provided a single AVIOContext, with a write() function that passes thro

Why can't you just set this in your application?
Not everyone is listening on a full setup where they can hear the dynamic range.

In the case of most calls to end_ebml_master, the target is within the current
segment, but in this case, it's in the first segment or header file, so if the
context was marked as non-seekable manually (as in segment.c), avio_seek will
ignore that and execute it anyway. This is fine in other use

This prevents sub-muxers from trying to seek back to the beginning of the
whole stream, only to find themselves overwriting some video data in the
current (often last) segment.
We only do this when not writing individual header/trailers.
