Hi,Everybody.
I use DM365 + DVSDK4.0.0.21 + H264Codec2.30.00.04 to encode a D1@Pal video and transmit it through a wireless device, whose bandwidth is 1.3Mbps max.
Encoder params use SLICE+GOP+VBR.
The average bitrate is 800Kbps,and I don't want to exceed to 1Mbps, But I cannot control the max bitrate. When in some scene, the bitrate will go to 2.5Mbps, which is unacceptable.
I have try CBR, but there is a "breathing" reflection(picture will shake in every IDR frame).
So VBR is the only way to achieve it?
Here is sample param settings:
stStaticEncodeParams.videncParams.encodingPreset = XDM_HIGH_QUALITY;
stStaticEncodeParams.videncParams.rateControlPreset = IVIDEO_STORAGE;
stDynamicEncodeParams.rcQMax = 45;
stDynamicEncodeParams.rcQMin = 0;
stDynamicEncodeParams.rcQMaxI = 42;
stDynamicEncodeParams.rcQMinI = 0;
stDynamicEncodeParams.rcAlgo = 1;
stDynamicEncodeParams.maxDelay = 100;
and the max bitrate is not work:
stDynamicEncodeParams.maxBitrateCVBR = 900000; or
stStaticEncodeParams.videncParams.maxBitRate = 900000;
So how can I use VBR but not exceed 1Mbps?
Here is my settings:
