[PATCH 0/7] MR10200: mf/tests: Add support for MF_TOPONODE_MARKIN_HERE to transform node.

[Brendan McGrath (＠redmcg)]

After a seek, Media Session may drop all samples with a PTS prior to the seek time.

It will drop the samples if they are output from a TopologyNode with the
MF_TOPONODE_MARKIN_HERE attribute set. If a sample starts before the seek time,
but ends after, it will be trimmed.

A trimmed sample will have its PTS adjusted to match the seek time, and its
duration reduced by the time removed.

If the sample is an uncompressed audio sample, it will also trim the samples content.
Removing the trimmed data from the beginning of the buffer.
