Hi There,
Does MSDK sample_decode_drm work for you ?
Can you send the output of following command line for understand your system ?
$ ls -l /dev/dri
$ lspci –nn | grep -i vga
Thanks,
Zachary

Today I tried again, and was able to run it. Please find the attached log for more details.
After running both decoder app (./simple_decode out_qsv.h264 raw ) and encoder app(./simple_encode -g 1280x720 -b 1000 -f 30/1 out_qsv.h264 op.mp4), i combined both audio and video file (output of encoder) using ffmepg (ffmpeg -i op.mp4 -i output.aac try.mp4 ).
When i played try.mp4, only audio track was coming, no video present (some blurred image was coming). Please let me know, is it the right way to verify the things or not? Please suggest me how to verify the outputs media SDK application.

Hi ,
The output of MSDK sample_encode is bare H264 stream, not mp4. can you check the parameter of ffmpeg when do the audio and video combination.
if you want verify the output of sample_encode, just playback the output. like use VLC or MSDK sample_decode with parameter -r.
Thanks,
Zachary
