First, since this is a TI codec, you should ask for it already XDC packaged. Given an XDC packaged codec, you should be able to just untar it into a directory, add that directory to your XDCPATH and begin using it from your app/config script.
---------------------------- The rest of this is background for the curious. There's some glossary here to help (interesting glossary words are highlighted in black): http://rtsc.eclipse.org/docs-tip/Glossary Every package has a name (defined in it's 'package.xdc' file), and the directory structure it's in must reflect that name. It can't arbitrarily be copied under the ce examples. The codec package is search for along the XDCPATH. Your statement below (highlighted in red) is not correct. The XDC tools don't recursively search deep into all directories on the XDCPATH, rather they just look for packages sitting in the directories named on the XDCPATH. So, if your codec is in a package named "ti.sdo.codecs.h264enc", it should be located in a directory ti/sdo/codecs/h264enc (e.g. you would find a file named 'ti/sdo/codecs/h264enc/package.xdc'). The directory which holds the 'ti' directory in this case, would be a repository, and would need to be located on the XDCPATH. While not necessarily recommended, if the Codec Engine examples are already on your XDCPATH (e.g., if your XDCPATH already includes dvsdk_1_40_00_28/codec_engine_2_10_01/examples), you could drop the codec package - with its fully qualified "ti/sdo/codecs/h264enc/..." name - into this examples/ repository. ---------------------------- And finally, if you're a codec vendor, or need to XDC package a codec library yourself, I'd recommend using the Codec Packaging Wizard: http://wiki.davincidsp.com/index.php?title=RTSC_Codec_And_Server_Package_Wizards It handles a lot of these naming details, as well as more complex issues like indicating stack usage and exported symbol name management for you.

Now, I go and build the dvsdk_1_40_00_28/codec_engine_2_10_01/examples/ti/sdo/ce/examples/server directory, and I get this message js: "/home/albertb/erezk_tests/dvsdk_1_40_00_28/xdc_3_00_06/packages/xdc/xdc.tci", line 275: exception from uncaught JavaScript throw: Error: xdc.loadPackage: can't find package 'ti.sdo.ce.examples.codecs.h264enc' along the path '/home/albertb/erezk_tests/dvsdk_1_40_00_28/codec_engine_2_10_01/examples/ti/sdo/ce/examples/servers/all_codecs/../../../../../..;/home/albertb/erezk_tests/dvsdk_1_40_00_28/codec_engine_2_10_01/packages;/home/albertb/erezk_tests/dvsdk_1_40_00_28/xdais_6_10_01/packages;/home/albertb/erezk_tests/dvsdk_1_40_00_28/dsplink-davinci-v1.50-prebuilt/packages;/home/albertb/erezk_tests/dvsdk_1_40_00_28/cmem_2_10/packages;/home/albertb/erezk_tests/dvsdk_1_40_00_28/framework_components_2_10_01/packages;/home/albertb/erezk_tests/dvsdk_1_40_00_28/biosutils_1_01_00/packages;/home/albertb/erezk_tests/dvsdk_1_40_00_28/bios_5_32_01/packages;/home/albertb/erezk_tests/dvsdk_1_40_00_28/xdc_3_00_06/packages;/home/albertb/erezk_tests/dvsdk_1_40_00_28/codec_engine_2_10_01/examples/ti/sdo/ce/examples/servers/all_codecs/./../../../../../..;'; try redefining the package path (XDCPATH). I understand that XDC can not find the codec, but why? As far as I understand, it should scan all the subdirectories of all the directory list in XDCPATH until it finds the required codec. If this is correct, the h264enc is (deep) under the dvsdk_1_40_00_28/codec_engine_2_10_01/examples directory, that is pointed by the "'/home/albertb/erezk_tests/dvsdk_1_40_00_28/codec_engine_2_10_01/examples/ti/sdo/ce/examples/servers/all_codecs/../../../../../.." directoy in the XDC path What am I doing wrong? -- Albert Burbea Harishonim 8 Ramat Gan 52502, Israel Tel/Fax + 972-3-7526016 Mobile: +972-52-3541842
