sir:

         using sample_multi_transcode_drm transcoding 1080p.h254(900 frame), sometime, the sample_multi_transcode_drm dont end its process which still use memory and cpu(very little),  and the transcoding file only part is completed.    i use the command "top", get the fact what the sample_multi_transcode_drm would always be  here, the content of transcoding result file dont change. 

        if i want to end the process of the sample, i must using "kill PID" command.

Hi Shiyin, 

To debug this better can you give us more details about the issue you have reported above like system details-processor and graphics info, the cmd line you are using? I have tried this multiple times scenario at our end and didn't the issue. Process is killed on it's own after the file write completes.The cmd line I have used for my testing - 
./sample_multi_transcode_drm -i::h264 ducks.h264 -o::h264 out.h264 -w 1920 -h 1080 -b 10000 -f 30 -hw

Can you confirm if you have modified the sample and are you seeing this issue with a particular input? Is this issue only seen with sample_multi_transcode or with other samples as well?
Please let us know your findings. 

Thanks,
Surbhi

sir:

          i use ./sample_multi_transcode_drm -i::h265 ducks.h265 -o::h265 out.h265 -w 1920 -h 1080 -n 900 -b 1000 -f 30 -hw -pe  e5400a06c74d41f5b12d430bbaa23d0b, but the problem come. i need some time to test the problem.

Hi, 

It wasn't clear from your earlier post whether you are doing h264 or h265 transcode. I am wondering what are your system specifications and which Media Server Studio and sample version are you using? Please confirm o/p of below tests- 

1. If behavior is only seen for HEVC to HEVC transcode?
2. Any specific inputs causing this? Please send us the input to reproduce this issue at our end. 
3. Do you see same issue when doing HEVC encode or decode only?

Thanks,
Surbhi
