Description Jean-Yves Avenard [:jya] 2023-02-26 01:51:57 PST 
Following bug 252938; under memory pressure memory eviction will occur in all active ManagedSourceBuffer.

The current eviction algorithm will only evict data prior the current playtime and in future data non-contiguous from the currently played segment.

We should fully clear non active source buffers or non-active tracks if possible.
