H264 Auto key frame controls method

[Elston]

I have set the H264 encoder to generate the IFrames automatically. But after debugging I see that internally the key frame control method is set to interval with the interval set to 250.

I thought auto should really have generated an IFrame whenever required. Am I missing something here? If so can someone point me out to the right way of setting the Auto mode.

Thanks,

Elston,

How did you set the key frame control? If it is automatically set the key frame, it needs to set the encoding parameters as follows before init the encoder():

key_frame_controls.method=0;
key_frame_controls.interval=0;

Also which version of Intel IPP are you using?

Thanks,
Chao

I am using IPP 6. I am settingkey_frame_controls.method = UMC::H264_KFCM_AUTO and not setting any value for interval.

However on debuging I see that it internally setskey_frame_controls.method = UMC::H264_KFCM_INTERVALandkey_frame_controls.interval = 250

Hi,

Could you have a check on the new 7.0 release? I think this feature was added in the new release.

Thanks,
