Hello TI,
We're using EzSDK and run the h.264 encoder When we set frame-rate, occasionally, the output bit-rate drops, which indicates that the encoder doesn't use the new frame-rate value to properly calculate the bits budget per frame.
For example when bit-rate is set to 1500kbps and frame rate is 50FPS, all is well, and the output bit-rate is indeed around 1500kbps. When we set new frame-rate to 25FPS and reduce the number of frames accordingly, without changing anything else, we occasionally get just ~750kbps on the encoder output.
can you please advise ?
static void frameRate( OpenMAX::ComponentHandle & handle, unsigned frameRate )
{
OMX_VIDEO_CONFIG_DYNAMICPARAMS parameters = OpenMAX::ComponentParameters::initParameterStruct< OMX_VIDEO_CONFIG_DYNAMICPARAMS >();
OpenMAX::ComponentParameters componentParameters( handle );
parameters.nPortIndex = OMX_VIDENC_OUTPUT_PORT;
componentParameters.getConfig( OMX_TI_IndexParamVideoDynamicParams, parameters );
parameters.videoDynamicParams.h264EncDynamicParams.videnc2DynamicParams.targetFrameRate = frameRate * 1000;
parameters.videoDynamicParams.h264EncDynamicParams.videnc2DynamicParams.forceFrame = IVIDEO_NA_FRAME;
componentParameters.setConfig( ( OMX_INDEXTYPE ) OMX_TI_IndexParamVideoDynamicParams, parameters );
}
