>Then this while loop can look identical to the while loop above.

In the first while loop of evictCodedFrame, there is a process to add thirtySeconds to rangeStart and rangeEnd.
Even if this process is repeated, rangeStart will not be larger than maximumRangeEnd before rangeEnd.
Therefore, the removable MediaSamples in the range from rangeStart to maximumRangeEnd is removed.

I think it is correct to compare the end of the range(rangeEnd) when processing in descending order, and the start of the range(startRange) when processing in ascending order.
