Linux/TDA2EVM5777: 3D Surround Encoder fail

Dawei Zhang

Part Number: TDA2EVM5777

Tool/software: Linux

Hi ,

I'm developing base on lvds_vip_multi_cam_3d_srv demo. I try to dump 4CH Original(1280*720) video & 1CH display(880*1080) video.

I use the Merge_Link merge 4CH original video with 1CH display video. It will pass 5CH to encode. When the application run few seconds. The terminal

prints fail "Assertion @ Line: 1793 in iva_enc/encLink_common.c: chId == pReqObj->InFrameList.buffers[i]->chNum : failed !!!".

What 's the reason? Is the encoder encode speed is too slow or something else?

Thanks.

Zhang.

Hi Zhang ,

what is number of channels created as encoder . ?

Hi Chetan,

Here is the create log:

CH0~3 is the original video.
CH4 is stiching video
I scale the CH4(stiching video, original 880*1080), and the APP can run normally. But the stiching video is not what i want.
Can codec encode different resolution video at the same time? Thanks.

Best,
Zhang

yes ,

IVA (encoder hardware) has the capability,

You need to configure the encoder for that,
This is not validated in the vision sdk package.

Hi Chetan,

I can only find this configuration is APP code:

//set configuration to h264
//pLinkChPrm->format = SYSTEM_IVIDEO_H264BP;
pLinkChPrm->format = SYSTEM_IVIDEO_H264HP;
pLinkChPrm->profile = 100;
pLinkChPrm->dataLayout = VENC_FIELD_SEPARATED;
pLinkChPrm->fieldMergeEncodeEnable = FALSE;
pLinkChPrm->enableAnalyticinfo = 0;
pLinkChPrm->enableWaterMarking = 0;
pLinkChPrm->maxBitRate = -1;
pLinkChPrm->encodingPreset = SYSTEM_XDM_MED_SPEED_HIGH_QUALITY;
//pLinkChPrm->encodingPreset = SYSTEM_XDM_HIGH_SPEED;
/* Set encodingPreset to SYSTEM_XDM_USER_DEFINED
* if SEI/meta data needs to be enabled */
/* pLinkChPrm->encodingPreset = SYSTEM_XDM_USER_DEFINED; */
pLinkChPrm->rateControlPreset = SYSTEM_IVIDEO_LOW_DELAY;
pLinkChPrm->enableHighSpeed = FALSE;
pLinkChPrm->enableSVCExtensionFlag = FALSE;
pLinkChPrm->numTemporalLayer = 0;
pLinkChPrm->overrideInputScanFormat= 0;
pLinkChPrm->fieldPicEncode = 0;
pLinkChPrm->IDRFrameInterval = 1;

pLinkDynPrm->intraFrameInterval = 30;
pLinkDynPrm->targetBitRate = 10*1000*1000;
pLinkDynPrm->interFrameInterval = 1;
pLinkDynPrm->mvAccuracy = SYSTEM_IVIDENC2_MOTIONVECTOR_QUARTERPEL;
pLinkDynPrm->inputFrameRate = 15;
pLinkDynPrm->rcAlg = 0;
pLinkDynPrm->qpMin = 0;
pLinkDynPrm->qpMax = 51;
pLinkDynPrm->qpInit = 25;
pLinkDynPrm->vbrDuration = 8;
pLinkDynPrm->vbrSensitivity = 0;
/* Set maxPicSizeRatioI to 1 for IDR or I-Frame only mode */
pLinkDynPrm->maxPicSizeRatioI = 640;

Do you mean reconfigure this or something else? Could you give me a configuration. Or where can i find a SDK have validated and can encode different resolution video.

Another question, If i set fps 30. I found some chunnel will drop frames. Fps 15 can work well. Or I configure encoder in low mode(low bitrate/format/encodingPreset) then frames will not drop. Is the codec's capacity is not enough.

Hi Chetan,

I can not find the IVA's performance data. Could you share me these. We may need to make a evaluation.
Thanks.

Zhang

Hi Chetan,

I change

pLinkChPrm->fieldMergeEncodeEnable = FALSE;
to
pLinkChPrm->fieldMergeEncodeEnable = TRUE;

Then I can record 4CH(1280*720) + 1CH(880*1080). But i found the fps is 15 even the original fps is 30; And there is new problem when i exit APP.
Log is here:
"
[HOST] [IPU2 ] 517.007899 s: ENCODE: Link ID 150995023: Stop in progress !!!
[HOST] [IPU2 ] 517.008052 s: ENCODE: Link ID 150995023: Stop done !!!

I'm not familiar with codec. Is my configuration correct?
