PXC_STATUS_ITEM_UNAVAILABLE trying to playback recorded data from rssdk file

[Jiawen_C_]

I recorded a .rssdk file using the Raw Streams example and am trying to programmatically read the data using the SDK. I recorded several files at various resolutions, framerates, and formats with the color stream only (depth, ir, left, right, all disabled). The files load fine in Clip Editor and I can export them through the interface to a directory of PNGs.

However, I can't seem to read it using the SDK. I followed the sample here: https://software.intel.com/en-us/blogs/2015/10/15/how-to-record-and-playback-streaming-sequences-in-intel-realsense-sdk

01	PXCSenseManager* sm = PXCSenseManager::CreateInstance();

02	pxcStatus sts;

03	// Set file playback name

04	sts = sm->QueryCaptureManager()->SetFileName(filename, false);

05

06	// Enable stream and Initialize

07	sts = sm->EnableStream(PXCCapture::STREAM_TYPE_COLOR, 0, 0);

08	sts = sm->Init();

I can confirm that SetFileName succeeds: if I give it an invalid filename, it correctly returns PXC_STATUS_FILE_READ_FAILED. sm->EnableStream also succeeds with PXC_STATUS_NO_ERROR. However, no matter what I do, sm->Init() fails with PXC_STATUS_ITEM_UNAVAILABLE.

I tried various combinations of sm->QueryCaptureManager()->SetRealtime(true / false) and ->SetPause(true / false) without any success.

I can further confirm that sm->QueryCaptureManager()->QueryNumberOfFrames() works correctly - returning the correct number of frames.

Surprisingly, even though sm->Init() fails, sm->QueryCaptureManager()->QueryImageSize(PXCCapture::StreamType::STREAM_TYPE_COLOR) returns the correct image size (correctly varying with which filename I pass in).

What am I doing wrong?

Have you tried to playback the clip using Raw Streams sample? If it doesn't work, please upload small failing clip to some share so we can check it.

I seem to have a similar problem trying to playback a recorded rssdk file. I use the example code from the documentation 

01	PXCSenseManager* sm = PXCSenseManager::CreateInstance();

02

03	// Set file playback name

04	sm->QueryCaptureManager()->SetFileName(filename, false);

05

06	// Enable stream and Initialize

07	sm->EnableStream(PXCCapture::STREAM_TYPE_COLOR, 0, 0);

08	sm->Init();

09

10	// Set realtime=false and pause=true

11	sm->QueryCaptureManager()->SetRealtime(false);

12	sm->QueryCaptureManager()->SetPause(true);

13

14	// Streaming loop

15	for (int i = 0; i < nframes; i+=3) {

16

17	// Set to work on every 3rd frame of data

18	sm->QueryCaptureManager()->SetFrameByIndex(i);

19	sm->FlushFrame();

20

21	// Ready for the frame to be ready

22	pxcStatus sts = sm->AcquireFrame(true);

23	if (sts < PXC_STATUS_NO_ERROR) break;

24

25	// Retrieve the sample and work on it. The image is in sample->color.

26	PXCCapture::Sample* sample = sm->QuerySample();

27

....

28

29	// Resume processing the next frame

30	sm->ReleaseFrame();

31

}

32

33	// Clean up

34	sm->Release();

The code works most of the time. However, when the recording includes any of the Depth + Confidence modes, the program crashes. It seems that the sense manager fails to initialize and line 8 sm->Init() returns error -3 PXC_STATUS_ITEM_UNAVAILABLE.

Curious if this problem has been resolved yet.
