getBufferedPosition() return value for live dash stream

[kanthicn1]

I am using getBufferedPosition( ) - getCurrentPosition( ) to get an estimate of the remaining playback buffer at any point of time, as suggested in #4023.

I am using a DASH test stream with fixed segmentDuration of 6 seconds to test this. When I observe the value returned by getBufferedPosition( ) alone, I expect it to increase in jumps of segmentDuration (6 seconds in my case). But, sometimes there is a slow ramp-up of this value which goes beyond segmentDuration during the segment download. (Attached plot of values for easier understanding).

I have no idea how this can be happening. If getBufferedPosition() only returns the presentation time of the last chunk in the queue, how can this value increase in granularity lower than segmentDuration? I hope my question is clear and some one can tell me what's going on.

I answered my question by following the code more closely. So, I will close this issue.
getBufferedPosition() doesn't always return the presentation time of the last chunk. The extractor "commits" decoded bits as and when they are decoded. So, the non-segment-duration increments in the buffer value makes sense.
