Intel Media SDK:2012
The article "Video Conferencing features of Intel Media Software Development Kit" tells thatlow latency encode and decode is a new feature of MSDK2012 for video conferencing applications.
I tested the different latencies of h264 encoder(the sample filter in MSDK)underdifferent presets:first, set the preset parameter to PRESET_LOW_LATENCY(m_EncoderParams.preset= CodecPreset::PRESET_LOW_LATENCY) , then set to PRESET_BEST_QUALITY.
Then,simply using a mirror to test the latency:
And I got the following data:
But the result shows that the latencies are very high(the resolution is only640*480),and arenearly the same with different presets.Why?
What latencies can you get with such test?
