Other Parts Discussed in Thread: OMAP3530

1.Is there any Sample Application for G711 codec to be used on DSP Side for OMAP3530 Board? 

2. When I am using encoding/decoding application the small "ti" logo is appeared at Display. how to disable this?

3.I want to display the local Image captured from camera on LCD but how to fill Buffer_Handle Parametes?

Regards,

Vineet

    I believe the example within dvsdk_3_00_00_29\codec_engine_2_20_01\examples\ti\sdo\ce\examples\apps\speech\dsponly will use the G711 codec on the DSP.

    The demo version of the codecs that come with the DVSDK will always have the TI logo, to run without the logo you need to use the production codecs which can be requested for free though here.

    This would depend on the format of your image and what the driver is configured to display, you may not have to do much at all. For an example of displaying an image from memory take a look at OMAP35x_SDK_1.0.2\examples\demo.c. This application uses the frame buffer driver to display bitmap RGB images using the default parameters, if your image from the camera is in the same format you can use the same display method. For further details on the display driver please reference chapter 6 of OMAP35x_SDK_1.0.2\docs\OMAP35x\UserGuide_1_0_2.pdf.

    Quick clarification, the Codec Engine examples that use a g.711 codec always use the _example_ g.711 codec distributed the XDAIS product, not the product-quality g.711 codec provided by TI's codec team (and, I think, with the DVSDK).  It should work fine and be fully functional, but it's not performance optimized at all for the C64+ device - just a C-reference implementation.

    And one more, the speech/dsponly example Bernie mentioned only builds for a BIOS-based system (e.g. single processor DSP like DM6437 or DSP-only side of an OMAP3).  Not sure what you're looking for, but this example doesn't provide the build/config for an ARM-based app that runs a _remote_ g.711 codec.
