Details

Bug is a sub-task of bug 1118126. To properly implement the range removal algorithm we need to be able to identify where the random access points in a track buffer are located. In fragmented mp4, those are: Stream Access Point of type 1 or 2 as defined in Annex I of ISO/IEC 14496-12. (ref http://www.w3.org/2013/12/byte-stream-format-registry/isobmff-byte-stream-format.html#iso-random-access-points) In webm, this is the start of a Cluster (e.g last resync point). WebM parser provides an API to retrieve those (GetOffsetForTime), mp4 MoofParser doesn't. API needs to be added to ContainerParser.
