Slice Based Encoding on OMAP5

Hello Pushpa,

I suggest you taking a look on a similar thread e2e.ti.com/.../767443

Hi Yanko,

I have set the configurations accordingly as mentioned in the referred post

/************** Encode Preset Mode *************************/

OMX_VIDEO_PARAM_ENCODER_PRESETTYPE presetType;

presetType.eEncodingModePreset = OMX_Video_Enc_User_Defined

err = mOMX->setParameter(
mNode,(OMX_INDEXTYPE) OMX_TI_IndexParamVideoEncoderPreset,
&presetType, sizeof(presetType));

/************************* Slice COding Type **************************/

OMX_VIDEO_CONFIG_SLICECODINGTYPE slicetype;

slicetype.eSliceMode = OMX_VIDEO_SLICEMODE_AVCByteSlice;
slicetype.nSlicesize = 1000;

err = mOMX->setConfig(
mNode, (OMX_INDEXTYPE)OMX_TI_IndexConfigSliceSettings, &slicetype, sizeof(slicetype));
CHECK_EQ(err, (status_t)OK);

/************************* Data Sync Mode for Input ********************/

OMX_VIDEO_PARAM_DATASYNCMODETYPE dataSyncMode;

ataSyncMode.eDataMode = OMX_Video_EntireFrame;

err = mOMX->setParameter(mNode,(OMX_INDEXTYPE)OMX_TI_IndexParamVideoDataSyncMode,
&dataSyncMode, sizeof(dataSyncMode));

/************************** Data Sync Mode for Output ****************/

OMX_VIDEO_PARAM_DATASYNCMODETYPE dataSyncMode;

ataSyncMode.eDataMode = OMX_Video_SliceMode;

err = mOMX->setParameter(mNode,(OMX_INDEXTYPE)OMX_TI_IndexParamVideoDataSyncMode,
&dataSyncMode, sizeof(dataSyncMode));

Also getBufferFxn and PutBufferFxn callbacks are implemented

But  I am getting following error during getBufferFxn call

Hello Pushpa,

You need to set getBufferFxn and putDataFxn call back functions to send the partial output buffer to encoder and to get the slice data from encoder along with setting outputDataMode to IVIDEO_SLICEMODE.

Slice output from OMX encoder is possible but not in low-latency mode. i,e encoder encodes full frame as a group of slices. If this is what you want this can be supported with proper setting of OMX encoder.

Try to apply following initial configuration:

OMX_VIDEO_PARAM_DYNAMICPARAMS dynamic_params;

OMX_INIT_PARAM(&dynamic_params);
dynamic_params.nPortIndex = OMX_VIDENC_OUTPUT_PORT;

OMX_GetParameter(encoder_handle, OMX_TI_IndexParamVideoDynamicParams, &dynamic_params);

IH264ENC_DynamicParams *h264_params = &dynamic_params.videoDynamicParams.h264EncDynamicParams;

h264_params->sliceCodingParams.sliceCodingPreset = IH264_SLICECODING_USERDEFINED;
h264_params->sliceCodingParams.sliceMode = IH264_SLICEMODE_BYTES;
h264_params->sliceCodingParams.sliceUnitSize = 1300;
h264_params->sliceCodingParams.streamFormat = IH264_BYTE_STREAM;

OMX_SetParameter(encoder_handle, OMX_TI_IndexParamVideoDynamicParams, &dynamic_params);

Hi Yanko,

Yes currently Ducati implements getBufferFxn and putDataFxn callback functions to send the partial output buffer to encoder and to get the slice data from encoder along with setting outputDataMode to IVIDEO_SLICEMODE.

Also I have set following parameters

h264_params->sliceCodingParams.sliceCodingPreset = IH264_SLICECODING_USERDEFINED;
h264_params->sliceCodingParams.sliceMode = IH264_SLICEMODE_BYTES;
h264_params->sliceCodingParams.sliceUnitSize = 1300;
h264_params->sliceCodingParams.streamFormat = IH264_BYTE_STREAM;

I can see from that logs that the frame is encoded with multiple slices, but fails after some 7 or 8 iterations. I have attached the logs

Please let me know if anything more is needed to configure
