video on demand chunk size

Hi There,

I am using Http Streaming for Video On Demand. Everything works well.

Currently I got an issue that I wanna add a feature that can manually change bit rate.

This is done and works, however the time that starts taking effect is around 6 seconds.

I think this is determined by the chunk size. So I set the chunk size to 2 second, but it still doesn’t work.

I did change the property to this:

sanjoseChunkDurationTarget

2000

Integer

Can someone explain or direct me to the right path?

Thank you

You also have to adjust the key frame frequency. Take a look at this article:

I don’t think you can do it per session or per stream, but you can do per application instance something like this:

appInstance().getLiveStreamPacketizerProperties().setProperty("cupertinoChunkDurationTarget", "10000");

Thank you Richard,

What if I need to play different video files with different key frame frequencies, as the chuck size is set.

Thank you Richard, I think I will stick with this
