HI,

 On going through sample_full_transcode provide @ https://software.intel.com/sites/default/files/MediaSamples_Windows_5.0.491.98719.msi

I observed trancoding video is good with Software acceleration, on providing hardware acceleration option video is not converted properly facing lot issue.

Please find the information below:

System info:
    CPU:    Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz
    OS:    Microsoft Windows 7 Enterprise 
    Arch:    64-bit

Intel(R) HD Graphics                         9.17.10.3517        Active

Commandline : sample_full_transcode.exe -i "c:\1\Sample.mp4" -o c:\1\out.m2ts -v:b 1000 -acodec:copy -hw

player used : VLC

Issue nature : after completing in transcode using hardware acceleration , on opening file in VLC player progress status of video is end, if we try fast forward video getting struct and only i am able to hear audio no video seen. Note: Same issue is not happening when i used software acceleration in command line.

Also attaching media analyzer log and snapshot off issue in attachment.

Hi Ram,

I have checked it on my system(i5-4300U) and I didn't see any issue with HW. From your analyzer logs it seems that HW is not supported from API version 1.5, can you please query which version is being used? 
Also you are using a 2nd generation system, due to which it is possible that it would not support MSDK capabilities completely. 

Thanks,
-Surbhi

Hi Ram, 

Thank you for reporting the issue. Unfortunately, we are not able to download the system analyzer, can you please upload it again. Also can you please download latest drivers from downloadcenter.intel.com. It can might be a driver issue. Please let us know your results with latest driver.

Thanks,
-Surbhi

I have also tested on haswell[4th Genration ] system and the sample is working fine and use API version 1.7

where as in 2nd and 3rd Generation it use API version 1.4 only, so this might be reason for the issue.

still i am doing lot of testing :) 

@Surbhi thanks for the information.

Regards,
RAM S
