I use m_pmfxSession->SyncOperate(...,MSDK_ENC_WAIT_INTERVAL);
I find SyncOperate take 60ms.
My video frame resolution is 1920*1080
How to improve it?

Thanks

I met the same problem too. Posted it and got Petter's answer. His reply is very helpful.
BTW, You have to give more information about how do you use SyncOperate at your encoder side. The most possible reason is how fast to clean encoded buffer in CEncTaskPool. If you are using RTP streaming, you have check your network speed.

Hi kkbee,

If low encode or decode latency is important to your usage I suggest you take a look at the following paper:

And thanks for your input Jiuxiang.

Hi,
Thanks for jiuxiang and Petter's response.
How can I know ifI set low latency success or not?
Do you have any data about how much latency this library require in low latency and non-low latency mode.

Thanks

Hi kkbee,

If you follow the suggested decoder and encoder configuration you should see latency below 10ms (especially if you are using HW codec).

Petter
