  • Forum Post: Re: IUNIVERSAL_Status

    Chris Ring
    A bit of background may be needed, and the docs can definitely be cleaned up. In general, the *_Status structs (in all XDM interfaces, including IUNIVERSAL) are algorithm 'output' from a control() call. The mention of 'read only' in the doc is from the caller/app POV - the intent is...

  • Forum Post: Testing h264Dec rev.2.00

    Ja Maitan
    We are in the process of testing the h264dec rev.2.00. To run the test we need to build a test app that can display a video clip downloaded into dm6437 eval board. I am using CCS 3.3. As a test template, I used testAppDecoder.pjt which comes with h264dec distro (on my computer it is in "D:\dvsdk_2_00...

    jialin fan
    hi, these days I was implementing a new codec on dm6446, and then I used xdm to encapsulate this codec, later I added it into the decodeCombo.x64P, meanwhile I use decode demo to test the new decodeCombo.x64P. when I was using the xdm to encapsulate the codec, I realized these functions: #pragma CODE_SECTION...

  • Forum Post: Re: Specific H264 codec parameters (how to set?)

    Chris Ring
    There is an article with some details on extending XDM structs (and fields). Typically, you'll #include the codec-provided ih264venc.h file to get the codec-specific definitions, then you can use those definitions when initializing the XDM fields. Chris

  • Forum Post: How to build the *.l64 to pass QualiTI checking?

    JuliannH
    Hi there, I'm trying to make a speech codec XDM-compliant to pass the QualiTI checking. When I use CCSv3.3 to build the input of QualiTI (say, **.l64), CCS has problems to locate some certain header files like: #include <ti/xdais/dm/isphdec1.h> #include <xdm.h> .... I probably can...

  • Forum Post: Re: Need Clarification on XDM :: Data Structures

    Chris Ring
    So long as you assign params.size = sizeof(IVIDDEC1_Params), it doesn't matter whether the struct you allocate in your app is "really" sizeof(IVIDDEC3_Params) big or sizeof(IMP2DEC_Params) big. The codec won't know. As a recommendation though, if your test app _really_ only want...

    Hi, I am working in Video Codec testing & as of now i am doing a test procedure which is now being doubted by my colleagues. Normally we used to run codec with Base class params mode or with Extended class variables (if codec supports) My Way of test Procedure for Basic Param from my understanding...

  • Forum Post: Re: DM365 MPEG4 encode noise at inputWidth>=160

    Chris Ring
    By design, the codec is supposed to indicate whether the encoded output buffer was filled by the codec using the CPU - my understanding is that the codec indicates this via the IVIDENC1_OutArgs.encodedBuf.accessMask field. If that field has the XDM_ACCESSMODE_WRITE bit set, the codec wrote into that...

  • Forum Post: Re: VoLIB/Codec Server Integration

    Dennis E
    Thanks for the reply, Our purpose for looking at this library is to process the audio to detect the presence or absence of speech. 8kHz is probably fine. I know the VAU component supports XDAIS. Does it make more sense to try to export this component directly by our codec server or to write a "wrapper...

  • Forum Post: VoLIB/Codec Server Integration

    Dennis E
    We have a need to integrate algorithms from the VoLIB into our existing codec server (for the OMAP3530/C64+). Our server currently contains a number of audio & video encoders and decoders, as well as a custom video processing algorithm we wrote in-house that uses DSPLIB 2.1, IMGLIB 2.01, and VLIB...

  • Forum Post: Re: how to implement extra function (for example, process and control) for writting warppers around g729 codec.

    Chris Ring
    If you're using Codec Engine you use the APIs appropriate for the XDM class. For example, if your codec implements ISPHENC1, you'll use Codec Engine's SPHENC1 APIs . If you're not using Codec Engine but rather just invoking the codec directly, you'll have to call the fxns through...

    Frank Talbot
    Hi, We're testing an in house encoder application that uses TI's H.264 Platinum encoder (v. 2.10.00.06) on a DM365 eval board. The example application that comes bundled with the encoder works, so I know the right pieces are in place in Linux. When we try to run our encoder application...

    According to the following TI wiki page: http://processors.wiki.ti.com/index.php?title=RTSC_Codec_And_Server_Package_Wizards there should be some sort of RTSC Codec Package Wizard that was used to create the packages found in c64xplus_g711_2_00_000_production. Likewise there should be some sort of...

    Hello Janet, You still haven't answered my question. I have already been two both wiki pages, and neither page provides enough information on how to "consume" a package. Likewise, on the Codec Engine wiki it says: "If you intend your algorithm to be consumed by Codec Engine,...

    Hello, I haven't seen the first five compilation errors that you listed in your posting. I believe that they were caused by difference in our tool chain paths, which in turn affect our respective include paths, i.e. "${CG_TOOL_ROOT}/include" "C:/ti/xdctools_3_22_03_41/packages"...
