Hi,

I need some help to implement 720P

We use IPNC_RDK_V2.8.0, FullFeature usecase, and want to change the data flow D1 to 720P.

We Modified the file "multich_tristream_fullFeature.c" as below:

...

pCameraOutPrm = &pCameraInstPrm->outParams[1];

pCameraOutPrm->dataFormat = SYSTEM_DF_YUV420SP_VU;

pCameraOutPrm->scEnable = FALSE;

pCameraOutPrm->scOutWidth = 1280; // 720

pCameraOutPrm->scOutHeight = 720; // 480

pCameraOutPrm->standard = SYSTEM_STD_720P_60; // SYSTEM_STD_NTSC;//SYSTEM_STD_PAL;

pCameraOutPrm->outQueId = 1;

...

encPrm.chCreateParams[1].defaultDynamicParams.inputFrameRate = 60; //30

...

But it doesn't seem to acting, as I saw by VLC, it's resolution remains 720*480.

I wonder if it support 720p use this method, or any other advice ?

by the way, it works when modified to SYSTEM_STD_PAL(720*576) using above method.

Thanks alot!

Jacky.

Below is serial port info, no error occurs:

[m3video] 13297: ENCODE: Creating CH1 of 1280 x 720, pitch = (1280, 1280) [PROGRESSIVE] [NON-TILED ], bitrate = 2000 Kbps ...

Hi Pei,

Which IPNC RDK release version are you using?

Hi, Rajat

We use IPNC_RDK_V2.8.0.

I've tried to modify the 1080P to 720P by two ways:

1. Modify the CameraOut param, then both the 1080P_H264 and 1080P_MJPEG should changed to 720P,

but it's failed.

2. Add Scaler Link to 1080P_H264 and 1080P_MJPEG to change the resolution, and the MJPEG chain works fine, but the H264 failed.

It seems that some bugs in the H264 Encode module:

=====code=====

encLink_h264.c --> enclink_h264_set_algObject() -->

UTILS_assert((status->videnc2Status.bufInfo.minOutBufSize[i].bytes < algCreateParams->mvDataSize));

=====code=====

the "algCreateParams->mvDataSize" changes according to the resolution, but "status->videnc2Status.bufInfo.minOutBufSize[i].bytes" remains the same in both the condition of 1080P and 720p.

So, do you test 720P_H264 in this version?

And the D1 chain, could be changed to CIF, QCIF, etc... if yes, how ?

Thanks very much.
