why framePackingSEIParams dose not take effect

HW:Dm8168

SW:EZSDK 5.05.1.4

We set the framePackingSEIParams parameter as:

tStaticParam.videoStaticParams.h264EncStaticParams.stereoInfoParams.stereoInfoPreset=IH264_STEREOINFO_ENABLE_DEFAULT;
tStaticParam.videoStaticParams.h264EncStaticParams.stereoInfoParams.topFieldIsLeftViewFlag= 1;
tStaticParam.videoStaticParams.h264EncStaticParams.stereoInfoParams.viewSelfContainedFlag=0;

tStaticParam.videoStaticParams.h264EncStaticParams.framePackingSEIParams.framePackingPreset=IH264_FRAMEPACK_SEI_ENABLE_DEFAULT;
tStaticParam.videoStaticParams.h264EncStaticParams.framePackingSEIParams.framePackingType= IH264_FRAMEPACK_SIDE_BY_SIDE;
tStaticParam.videoStaticParams.h264EncStaticParams.framePackingSEIParams.frame0PositionX=0;
tStaticParam.videoStaticParams.h264EncStaticParams.framePackingSEIParams.frame0PositionY=0;
tStaticParam.videoStaticParams.h264EncStaticParams.framePackingSEIParams.frame1PositionX=8;
tStaticParam.videoStaticParams.h264EncStaticParams.framePackingSEIParams.frame1PositionY=0;

eError = OMX_SetParameter (pHandle, OMX_TI_IndexParamVideoStaticParams,
&tStaticParam);

But ,there is no change in the h264 bitstream.

Hello,

You could check the h264 dec user guide.

By default the frame packing SEI encoding coding params is disable.

If you want to enable it, the framePackingPreset should be set to IH264_FRAMEPACK_SEI_ENABLE_DEFAULT or IH264_FRAMEPACK_SEI_USERDEFINED per the user guide.

Have you try set it as USERDEFINED?

Best Regards,

Margarita

Hello,

I am not a codec expert but could you try to disable stereoInfoPreset and in case Frame packing SEI coding is enabled then input content type (coding type) should be Progressive coding.

Let me know the result.

Best Regards,

Margarita
