MFXVideoENC_ProcessFrameAsync can be used for bitstream encoding ( PAK)

Hi,

In the Media encoding pipeline  we do  Mode decision(ENC) and Bitstream packing (PAK) to encode a frame.

I see in one of the examples fei_encpak,cpp files we use the "ProcessFrameAsync" API to invoke ENC or PAK by passing different parameters like the following.

m_pmfxENC->ProcessFrameAsync(&eTask->in, &eTask->out, &m_SyncPoint);

m_pmfxPAK->ProcessFrameAsync(&eTask->inPAK, &eTask->outPAK, &m_SyncPoint);

but in the mediasdkembedded-man document there is no mention of PAK processing using this API.

my question is ,can i use the  "ProcessFrameAsync" API to invoke PAK as well ,as mentioned in the example code?

Thank you
