@ -80,9 +80,31 @@ Proposition:
decision.
Things to query:
- pad can do real random access (downstream peer can ask for offset != -1)
- min offset
- suggest sequential access
- max offset
- align: all offsets should be aligned with this value.
- pad can give ranges from A to B length (peer can ask for A <= length <= B)
- min length
- suggested length
- max length
Use cases:
- An audio source can provide random access to the samples queued in its
DMA buffer, it however suggests sequential access method.
An audio source can provide a random number of samples but prefers
reading from the hardware using a fixed segment size.
- A caching network source would suggest sequential access but is seekable
in the cached region. Applications can query for the already downloaded
portion and update the GUI, a seek can be done in that area.
- a live video source can only provide buffers sequentialy. It exposes
offsets as -1. lengths are also -1.
