I have another situation here with metadata. It is not behaving as I believe,
from reading the documentation, it should.
pair = insert_metadata(drop_metadata(master_source))
master_metadata_f = fst(pair)
master_meta = snd(pair)
...
s= switch(id="foo",
track_sensitive=false,
[({!baz}, master_meta), ({true}, s)]
The FIRST time that foo switches to master_meta, it correctly updates the
metadata on s to be what the insert_metadata sets it to.
When the stream fails, as it inevitably does, due to buffer underruns, the foo
switch switches to the original s, and updates the metadata.
BUT! When the stream at master_meta comes back, due to the buffer catching up,
the foo switch correctly switches back to it (can see it in the logs), but it
does NOT update the metadata.
The docs for switch() say:
replay_metadata (bool – defaults to true): Replay the last metadata of a
child when switching
to it in the middle of a track.
I'd read that to mean that, by default, it should be doing the right thing. But
it isn't.
Why isn't it doing that then? My (naive) understanding is that master_meta
still contains the last metadata it was set to. I'm logging the activity of
master_metadata_f, so I know with certainty that it's set correctly.
