The Intel Media SDK is unable to decode a stream of raw H264 video from a camera. Is Media SDK suitable for streaming applications?

[dmotw1]

Hey,

I am trying to decode an H264 video stream coming in from the camera but I keep getting ERR_MORE_DATA and it is never able to reach to the decoding phase of the code.

Platform:

Intel Atom E3950 (Apollo Lake)

OS:

Ubuntu 16.04 LTS

Steps Taken:

The setup required to run the Media-SDK is done by following documentation:

https://software.intel.com/en-us/articles/build-and-debug-open-source-media-stack

I am also able to run the sample projects provided on git successfully. Specifically, the sample_decode example is able to take in the raw H264 file and spit out the YUV format. This makes me assume there is no issue with missing drivers from Intel.

I also pulled the "decode" sample from tutorial and was able to run that and used it as my reference which I found at the following link:

https://software.intel.com/en-us/articles/media-sdk-tutorials-for-client-and-server

I also read the steps required to setup the Media SDK on the following link:

https://software.intel.com/en-us/articles/framework-for-developing-applications-using-media-sdk

Problem:

But none of this works. When I run my code the MFXVideoSession_DecodeHeader(Session, &Bitstream, &Videoparam) returns ERR_MORE_DATA. The buffer that is being passed has around 32000 bytes of data, I was able to check this value in the debugger. And the code is never able to get to the point of decoding phase and stays stuck here.

How can I solve this problem?

I am not sure if the intel Media SDK supports real time decoding and I would like more insight on that too.

Note:

The API version that I am able to query in the code gives me that it has Version 1.28. The repository was cloned from github a month back.

Thanks in advance.

Hey Alberto,

It looks like that this thread has already been moved to Embedded Products. Do I still need to do anything on my part for someone to respond to my question or just need to wait till they respond?

Thanks.

Hey Maecenas_INTEL,

Thank you for your response. Unfortunately, I cannot. However, when I was trying to build the Yocto image, I am facing some errors and the build fails. I can try and verify this on Yocto if I am able to build the Yocto image. Where can I post the Yocto errors? If you could provide me the link to that I would be grateful.

Also, by the time I can run the Yocto, is there a way you can help me debug the situation on Ubuntu.

Regards,

Devang
