wowza4.4.1: getStartTimecode() & getMaxTimecode()

Wowza Streaming Engine

Hi,

I am trying to find a duration of the stream for rtmp and hls.

I see that the

IMediaStream.getMaxTimecode()

returns a duration of the stream. (possibly rtmp? if the incoming stream is rmtp)

and

LiveStreamPacketizerCupertinoChunk.getStartTimecode()

for each TsChunk’s start time in milliseconds duration from the first ts chunk(0)

My question are,

  1. is this two timeCode are synced?

(I understand that there is a delay between the two but are they counted in the same way based on the same stream? or counted individually?)

  1. it looks like
LiveStreamPacketizerCupertinoChunk.getStartTimecode()

might be just a sum of each ts’s duration… is it a sum of the ts chunk’s duration or the actual timecode

Thank you

Oli

Hello Oli

  1. These two are not synced, and the answer to number 2 covers the reason for that.

  2. The LiveStreamPacketizerCupertinoChunk.getStartTimecode() returns the sum of each ts file’s duration in milliseconds.
