it will block in the following line:

OMTB-OMX_ErrorNone

OK

     

OMTB> omx api sendcommand state h264venc 0 waitforsem

 

why???

    You'll need to filter the buffers from the vpcc to the dei before passing them to the encoder.

    hi,Marcus Cooksey:

          You can look this post:

         http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/131892.aspx

     

        it should be possible to construct a pipeline with

        OMX-VFCC, OMX-TVP_CTRL (420SP, TVP7002 component-in)->OMX-H.264 VENC.

     

        But I fail to construct a pipeline as such. why?

    Hi Feng Xiao,

    Please find the attached modified omtb script which will solve the problem.

    The issue is with the configuration of "no of input buffers" of video encoder.

    VFCC -> H.264 Venc

    In the above usecase IL-Client (OMTB) "allocates the buffers on the output ports" of the VFCC component, these buffers are passed to the Input port of H.264 Venc component as "use buffer", so the no of allocated buffers should be same as no of use buffers.

    Thanks,

    Srinivas
