Hi all,
As the successive of this topic, I still couldn’t get IJPE run. Following the sample, my code is like:
/********************************* Initialization *********************************/
// Initialize NvMedia structures
err = NvSciBufModuleOpen(&bufModule);
err = NvSciSyncModuleOpen(&syncModule);
err = NvSciSyncCpuWaitContextAlloc(syncModule, &cpuWaitContext);
imageSize = m_width * m_height * 3;
LOG_DBG("NVDrive: Encode start, imageSize=%d\n", imageSize);
err = NvSciBufAttrListCreate(bufModule, &bufAttributeList);
status = NvMediaIJPEFillNvSciBufAttrList(NVMEDIA_JPEG_INSTANCE_0, bufAttributeList);
status = PopulateNvSciBufAttrList(
YUV420SP_8bit,
m_width,
m_height,
true, // needCpuAccess
NvSciBufImage_PitchLinearType,
2, // planeCount
NvSciBufAccessPerm_ReadWrite,
256U,
NvSciColorStd_REC709_ER,
NvSciBufScan_ProgressiveType,
bufAttributeList);
err = NvSciBufAttrListReconcile(&bufAttributeList, 1U,
&bufReconciledList, &bufConflictList);
appBuffer = static_cast<NvMediaAppBuffer*>(malloc(sizeof(NvMediaAppBuffer)));
memset(appBuffer, 0x0, sizeof(NvMediaAppBuffer));
err = NvSciBufObjAlloc(bufReconciledList, &appBuffer->bufObj);
ijpeCtx = NvMediaIJPECreate(bufReconciledList,
n_inputs, // maxOutputBuffering
MAX_BITSTREAM_SIZE, // maxBitstreamBytes
NVMEDIA_JPEG_INSTANCE_0); // HW instance id
/* The reconciled list is needed for later */
NvSciBufAttrListFree(bufAttributeList);
NvSciBufAttrListFree(bufConflictList);
status = sAllocEOFNvSciSyncObj(ijpeCtx, syncModule, &eofSyncObj);
status = NvMediaIJPERegisterNvSciSyncObj(ijpeCtx, NVMEDIA_EOFSYNCOBJ, eofSyncObj);
status = NvMediaIJPESetNvSciSyncObjforEOF(ijpeCtx, eofSyncObj);
/*********************************Image Processing*********************************/
// Convert dwImage from CUDA to NvMedia
CHECK_DW_ERROR_NOTHROW(dwImageStreamer_producerSend(m_cuda_image, m_streamerCUDA2NvMedia[inputNum]));
CHECK_DW_ERROR(dwImageStreamer_consumerReceive(&m_nvmedia_image, 1000, m_streamerCUDA2NvMedia[inputNum]));
dwImage_getNvMedia(&dw_nvmedia_image, m_nvmedia_image);
appBuffer->bufObj = dw_nvmedia_image->imgBuf;
// Compress image
status = NvMediaIJPEFeedFrame(ijpeCtx, appBuffer->bufObj, nvmedia_compress_quality, NVMEDIA_JPEG_INSTANCE_0);
// Rest of the code
The NvMediaIJPEFeedFrame() always return a NVMEDIA_STATUS_ERROR, which means all the error code doesn’t apply to this error.
One suspect from my side is from the description of the function NvMediaIJPEFeedFrame: NvMediaIJPESetAttributes() must be called at least once to configure NvMediaIJPE. Although I don’t have Huffmann Table or quantization-table, I tried to set the quality attribute like this:
NvMediaJPEncAttributes attr;
attr.quality = nvmedia_compress_quality;
status = NvMediaIJPESetAttributes(ijpeCtx,
NVMEDIA_IMAGE_JPEG_ATTRIBUTE_QUALITY,
&attr);
But it still doesn’t work . But honestly I don’t think I need to set it since the function NvMediaIJPEFeedFrame already has this argument.
NvMediaIJPEFeedFrame(
const NvMediaIJPE *encoder,
NvSciBufObj bufObj,
uint8_t quality,
NvMediaJPEGInstanceId instanceId
);
Any help is appreciated, thanks.
Best regards,
