1080p30 4channel encode & display usecase

If your output format is YUV420 in the capture path, you will not be able to use VIP portion in DEI driver since there is no free path available in the capture for the DEI.

Thx for reply.

I don't use 420out on Capture PATH.

My chain is as follows.

Capture(1080p30 * 4)  422OUT --> DUP ----> DEI(1080p30 * 4) --> 420OUT --> Encode (1080p30 * 4)

                                                                  |---> swMs(1080p30*4) --> Display

And, swMs cannot be created with any SC instance except SC5.

I decided to set display frame rate to 15.

And instead enabling dual output(420p/422p) of DEI.

So. my chain was changed to as follows.

Capture(1080p30 * 4)  --> DUP ----> DEI ---> 420out(1080p30 4ch) -----------> merge --> Encode (1080p30 * 4 + 480p30 * 4)

                                                                   |-> 422out(480p30 4ch) -> nsf ->|

                                    |---> swMs with SC5(1080p15*4) --> Display

But, there are frame drops in DEI 420P of DEIHQ out path about 20%(30fps->25fps)

I don't know the reason of fps drop.

This is detailed statistics of DEI

After some debug, I found that the frame drops came from encoder.

I assign encoder as follows.

static SystemVideo_Ivahd2ChMap_Tbl systemVid_encDecIvaChMapTbl =
{
.isPopulated = 1,
.ivaMap[0] =
{
.EncNumCh = 2,
.EncChList = {0, 1}, // 2ch 1080p30
.DecNumCh = 0,
.DecChList = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
},
.ivaMap[1] =
{
.EncNumCh = 2,
.EncChList = {2, 3}, // 2ch 1080p30
.DecNumCh = 0,
.DecChList = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
},
.ivaMap[2] =
{
.EncNumCh = 4, 
.EncChList = {4, 5, 6, 7}, // 4ch D1
.DecNumCh = 0,
.DecChList = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},
},
};

DEI_HQ's VIP out is connected to IVAHD0. and IVAHD0 cannot encode 2ch 1080p30.

But, if I disable swMs & display path, there's no frame drop.

Is encoder affected by swMs or display?

Hi, again.

I migrated to DVR RDK 4.1. And I found the MultichHD usecase

in dvr_rdk/mcfw/src_linux/mcfw_api/usecases/ti816x/multichhd_vcap_venc_vdis.c

I commented out ENABLE_FAKE_HD_MODE, because my custom board does not use TVP5158.

And the test result shows frame drops too.

Any idea?
