Hi Harsh,

Mohammad_T_1 · ‎09-13-2015

I am reading about Intel Media SDK from last 5 days but not able to start working with it, to stream frames for Encode/Decode in VC++, please help me with starter example. I have already linked it's lib to VC++ project and included Media SDK headers to it. Guide me please/

Harshdeep_B_Intel · ‎09-14-2015

Hello Mohammad,

Yes, we do have MediaSDK encode/decode samples that can help you get started, steps below

Download and install sample ver 6.0.068 from here: https://software.intel.com/en-us/media-client-solutions-support/code-samples.
Sample_decode.exe/Sample_encode.exe available at (installed path/_bin/x64/) and content at same path (_bin/content)
Example - decode command line : “sample_decode.exe h264 –i inputfile –o outputfile –hw -w -h

Let us know if any further questions:

Thanks,

Hi Harsh,

Error comes when i install Intel@MediaSamples6.0.0.48/49 Setup. Error message is:

The installer has encounter an unexpected error installing this package. This may indicate a problem with this package. The error code is 2503.

Now what is supposed to do.

Mohammad_T_1 · ‎09-15-2015

Hi Harsh

I got samples by installing Intel@MediaSamples6.0.0.49 Setup on other system. But in Project: sample_encode not able to understand how it is filling sInputParams structure from command line.? What parameters it is getting from command line to fill it's structure?

Harshdeep_B_Intel · ‎09-15-2015

HI Mohammad,

Can you send me you system information? Check and verify if you have latest driver installed on your system from here: https://downloadcenter.intel.com/. Share a log for analyzer tool at (Installed folder/media_sdk/tools/media_sdk_analyzer.exe). It will be interesting to investigate cause of error during samples installation.

Now, the version of samples you are downloaded MediaSamples6.0.0.49 is the old version. As I suggested in previous comment, install samples version ver 6.0.068 which are the latest. In sample_encode sInputParams structure accepts many parameters from the command line like target usage, codec, width, height and many more and the parameters accepted from command line by the structure is defined is pipeline_user.cpp file.

Also, samples are bit complex and we have a simplified samples (tutorials) using which you can understand the various parameters calls in mediasdk. Take a look at simple_3_encode tutorial to get started.

Thanks,

Hi Mohammad,

Thank you for logs. I tried on one of our system and was not able to see the installer issue. Can you try again installing latest samples version 6.0.0.68 after updating your system to latest drivers (15.40.7.4279) from here. Let me know how it goes.

Thanks,

AaronL · ‎09-16-2015

It was earlier suggested to use the sample_encode or sample_decode samples to understand how to create an application that makes use of the Intel Media SDK for encoding/decoding purposes. But, both of these samples are fairly complicated and not necessarily a good starting point for figuring this stuff out.

Instead, the tutorials, available at https://software.intel.com/en-us/articles/media-sdk-tutorials-for-client-and-server , are generally a much better way to learn how to develop software that uses the Media SDK, and then the sample_encode and sample_decode samples can be used for reference purposes but not as a starting point.

Harshdeep_B_Intel · ‎09-16-2015

Hi Aaron,

Thank you for your feedback. Agree, samples are bit complicated to understand as a starting point and we are working on making them simpler. Hence as part of the effort, as you pointed out and as suggested before "Also, samples are bit complex and we have a simplified samples (tutorials) using which you can understand the various parameters calls in mediasdk. Take a look at simple_3_encode tutorial to get started. " tutorials are good starting point for mediaSDK.

Thanks,

Hi Harsh ,

I updated Intel driver but samples code unable to run. But i have created my program from new sample_3_encode which you have provided. Till now i have done these things: 1- Initialize Session, 2- Set Parameters, 3- Done Query, 4- Allocate Surfaces. All this 4 steps successfully done but, now GetFreeSurfaceIndex( , ) function is not supported , i don't know why.

Few functions which are not working are: GetFreeSurfaceIndex( , ), MSDK_CHECK_ERROR( , , ), LoadRawFrame( , ), MSDK_BREAK_ON_ERROR(), MSDK_SLEEP(), MSDK_CHECK_RESULT( , , ).

Help me out about this issue, which Header or Library is required. I have already install INDE Media SDK. and included : #include"mfxaudio++.h"
#include"mfxvideo++.h"
#include "mfxjpeg.h"
#include <iostream>
#include <memory>
#include "mfxastructures.h"

and linked libmfx.lib.

Help me

Help me out please

Harshdeep_B_Intel · ‎09-17-2015

Hi Mohammad,

Please consider making following changes to code:

Include "mfxstructures.h" and "mfxdefs.h" header files.
The input file extension is (mp4) which is a container. As input codec ID is set to AVC, using a splitter tool,get the H264 bitstream and provide it as input. Please go through the media-sdk manual for input supported formats for mediasdk.
MSDK_CHECK_ERROR, MSDK_BREAK_ON_ERROR are defined macros, Please define them before there usage or attach "common_utils.h" header file.
I do not see MSDK_SLEEP defined in the code, these are OS- specific type definitions and has to be defined before used.

Please go through the tutorial code simple_3_encode carefully again, and define all the parameters before calling them and attach all required files as shown in tutorial.

Thanks,
