In Section 8.4.4, the selection of the first fragment to push to the Source Buffer is ambiguous, when random_access_time falls on a fragment boundary. When this happens, there will be two values of r for which
tk[k,r]≤ random_access_time and tk[k,r+1]≥ random_access_time
holds true.
This could potentially cause different receiver behaviour where the first fragment pushed may or may not be presented. Then, the observation that the total playback duration is a specific value would not be tenable.
