- Discontinuity on seek.
I only see a flush requirement, which probably does not need to be done
indirectly through blocks.
- On silence and packet loss.
Decoders should behave the same. Silence is more or less SPU.
Output previous buffers, then use new timeline, tag first block output
from the new timeline with discontinuity.
The complexity being the delayed timeline reset/packetization of
remaining blocks. (usually related to block_Bytestream usage *)
* which does not currently seems currently properly used for frame
consolidation cases in packetizers (ex: mpegaudio/SEND_DATA:).
