compare with mfx plugin, it will occurs different error message

Comment 2 sreerenj 2018-06-04 23:15:25 UTC 
This is an issue with Open source Media Driver. All jpeg samples are failing to decode with the media-driver.
All works fine with MediaServerStudio2017 release. Could you please have a try?

Please file a bug against the media-driver.
Comment 3 zj,wang 2018-06-05 07:14:25 UTC 
this issue can not be duplicated with close source MediaServerStudio2017, so it is a media-driver issue
please refer to https://github.com/intel/media-driver/issues/178
Comment 4 sreerenj 2018-06-27 21:47:12 UTC 
Closing as won't fix.
