[satinder_s_]

Hi ,

I am working on media sdk and I successfully installed media sdk on linux and I also installed intel media sdk with gstreamer . But gstreamer can not play a single video . Gstreamer giving following error every time :

gst_vaapi_decoder_parse assertion decoder != NULL failed

But using samples of media sdk I am able to play ES stream but that is play very fast when I am using -hw option , for -sw that is playing smooth . But I wanna play using -hw and I also wanna play other video formats so What I can do in that situation ? 

following are main issues : 

Gstreamer is not working 

media sdk -hw very fast and flickering

Hi,

We need more information to investigate your issue.

Could you give answers following questions?

* Platform, OS, MediaSDK version,

* Have you tried through gstreamer command line testing with "gst-launch-1.0"?

* Could you attach one of your ES?

* And if OS is linux, please collect "$ vainfo" output.

Regards,

Peter.

Actually I wanna use gstreamer for play ts file because media sdk only works on es .

[Ishmael_Sameen]

Can you remove gstreamer vaapi from your system? It should be in your LDPATH (libgstvaapi.so.x.xx)

[satinder_s_]

ok , I did not remove but I think we can remove it .

[satinder_s_]

I did not find and locate libgstvaapi.so.x.xx , So please let me know I can do now , Please help asap.

Hi Satinder,

It seems like you are using Media server sdk.

Its gold bkc is CentOS.

I know that it's tough to enable Media SDK in Ubuntu.

I have some suggestions.

1. Can you verify Media SDK operation with Media SDK samples here?

    - https://software.intel.com/en-us/intel-media-server-studio-support/code-samples

    If every tweak was correct and Media SDK is working good basically, these samples should be working also.

    You can just try sample_encode and sample_decode.

2. About elementary stream you are using,

    Is this output from Media SDK?

    if not, why don't you create sample from Media SDK and use for now?

Regards,

Peter.
