Linux/DRA746: some 264 streamer decode failed

Hi Gao, 

With latest SDK, I am not observing any error for elementary stream and you mp4 stream.

You can check the codec version with remote proc logs. Execute below command on target, it will show the versions of all codecs integrated with IPUMM

cat /sys/kernel/debug/remoteproc/remoteproc1/trace0

Thanks

Ram

Hi Gao,

Whether my ti decoder sdk version is older? The newer sdk maybe ok?

I did not see any error with latest CODEC release in standalone. Also Vega analyser did not show any error with extracted stream.

All the latest codec versions are here : https://git.ti.com/ivimm/ipumm/trees/master/extrel/ti/ivahd_codecs/packages/ti/sdo/codecs

Hi Gao,
The latest codec versions are as below:

Decoders:
1. H264D-02.00.21.01
2. MPEG4D-01.00.15.01
3. MPEG2D-01.00.17.01
4. VC1D-01.00.02.05
5. MJPEGD-01.00.16.01

Encoders:
1. H264E-02.00.09.01
2. MPEG4E-01.00.02.01

Hi Prashanth,

Can you print the frame number, inputBytes to the codec & bytesConsumed by the codec & share the log.

VIDDEC3_process mInCount 1, mInArgs->inputID=0xb5902f28, fd 0x20, mInput 0xb5a04000, size 3035, bytesConsumed 3035, timestamp 0.000, err 0

From log above, mInCount is the frame number, size is inputBytes to codec and bytesConsumed. And err is the result by codec.

I attach log named ti_264_decode_fail.zip for you.

Best Regrads.

Thanks Gao, for the logs.

Looks like some extended parameter setting is causing this issue. With Base class params it works fine. Please share the param settings. I will suggest you the modification required.

Hi Prashanth,

Thanks for you answer. Params are set below as shows:

int32_t DecoderH264::initCommonStaticParams()
{
    // xxx other codec support; viddec3test uses IVIDDEC3_Params
    mParams = (VIDDEC3_Params*)dce_alloc(sizeof(IH264VDEC_Params));
    if( !mParams ) {
        ERROR("DEC Parameter memory allocation failed");
        return -1;
    }
    mParams->size = sizeof(IH264VDEC_Params);
    mParams->maxBitRate      = 10000000;
    mParams->displayDelay    = IVIDDEC3_DISPLAY_DELAY_AUTO;
    mParams->numOutputDataUnits  = 0;

    // set the max width and height, as bigger as possible
    mParams->maxWidth            = 4096; //mWidth
    mParams->maxHeight           = 4096; //mHeight
    mParams->maxFrameRate        = 30000;
    mParams->dataEndianness      = XDM_BYTE;
    mParams->forceChromaFormat   = XDM_YUV_420SP;
    mParams->operatingMode       = IVIDEO_DECODE_ONLY;
    mParams->displayBufsMode     = IVIDDEC3_DISPLAYBUFS_EMBEDDED;
    mParams->inputDataMode       = IVIDEO_ENTIREFRAME;
    mParams->metadataType[0]     = IVIDEO_METADATAPLANE_NONE;
    mParams->metadataType[1]     = IVIDEO_METADATAPLANE_NONE;

    mParams->outputDataMode      = IVIDEO_ENTIREFRAME;
    mParams->numInputDataUnits   = 0;
    mParams->errorInfoMode       = IVIDEO_ERRORINFO_OFF;

    return 0;
}

int32_t DecoderH264::initSpecificStaticParams()
{
    ASSERT(mParams);
    mH264Params = (IH264VDEC_Params *) mParams;
    mH264Params->dpbSizeInFrames = IH264VDEC_DPB_NUMFRAMES_AUTO;
    mH264Params->pConstantMemory = 0;
    mH264Params->presetLevelIdc = IH264VDEC_LEVEL41;
    mH264Params->errConcealmentMode = IH264VDEC_APPLY_CONCEALMENT;
    mH264Params->temporalDirModePred = TRUE;
    mH264Params->detectCabacAlignErr = IH264VDEC_DISABLE_CABACALIGNERR_DETECTION;
    mH264Params->bitStreamFormat = IH264VDEC_BYTE_STREAM_FORMAT;
    mH264Params->decodeFrameType = mDecodeIOnly ? IH264VDEC_DECODE_I_ONLY : IH264VDEC_DECODE_ALL;
    DEBUG("mDecodeIOnly %d", mDecodeIOnly);
    return 0;
}

int32_t DecoderH264::initCommonDynamicParams()
{
    if (!mDynParams) {
        mDynParams = (IVIDDEC3_DynamicParams*)dce_alloc(sizeof(IH264VDEC_DynamicParams));
        mDynParams->size = sizeof(IH264VDEC_DynamicParams);
        mH264DynParams = (IH264VDEC_DynamicParams *) mDynParams;

        mDynParams->displayWidth  = 0;
        mDynParams->frameSkipMode = IVIDEO_NO_SKIP;
        mDynParams->newFrameFlag  = XDAS_TRUE;
    }

    // common parameters
    mDynParams->decodeHeader  = mDecoderHeader ? XDM_PARSE_HEADER : XDM_DECODE_AU;

    return 0;
}

int32_t DecoderH264::initSpecificDynamicParams()
{
    return 0;
}

First, I set decodeHeader to PARSE_HEADER mode because I want to parse w/h from stream header.

After I got stream resolution, set decodeHeader to DECODE_AU mode again.

Besides, I note that these params are work well for other 264 streams.
