WinEC 7 AM35x TI codecs missing in image

Other Parts Discussed in Thread: AM3517

Hi,

I found all the TI codecs in the path C:\WINCE700\3rdParty\dvsdk_wince_01_11_00_02\.

In my image I have checked all the components

 

But I don't have any files in my image (e.g. H264VideoDecoder.dll is missing). Why?

Best regards,

Andreas

    Hi,

    I noticed, that I need to add DVSDK as Subproject to my platform builder project to add the neccessary *.dll's to the release image. But now I get the following error message if I play an avi video with H264 codec:

    PID:05720022 TID:05E9002E H264: FPS will be printed after every 100 display frames

    I have add the following components to my image:

    At the moment I'm not sure, if the codecs are supported by the AM3517?

    Best regards,

    Andreas

    The issue you are running into is related to the AM35X processor.  AM35X does not include a DSP so it can not use the DVSDK functionality.

    So there is no MPEG-4 or H264 codec for AM35x available. Is this correct?

    Where can I get codecs for WinEC 7 and AM35x which also support NEON?

    The is correct there is no hardware codes for the AM35X.

    In WEC7 Microsoft does provide software codecs and could be enabled for WEC7.
