I was trying the DMAI based application in the DVSDK package on the DM6467 TI EVM.
The application is not able to detect the camera input and prints the following message on the console. [EMAIL PROTECTED]:/work/vrb_6467# ./encode -v vrb.264 Encode demo started. Error: Failed to detect input video standard, 720P component input connected? I have tried connecting the NTSC as well as PAL camera, and also a DVD player output to the VIDEO IN port of the DM6467 EVM. I am not sure as to what is going wrong in the DMAI application. The version numbers for the packages which I have are - dvsdk_1_40_00_21 - dmai_1_00_00_15 - codec_engine_2_10_00_15 - dvsdk_demos_1_40_00_14 – This is where the DMAI application resides. - dm6467_dvsdk_combos_1_11 – This is where the codec packages and server executable resides. - framework_components_2_10_00_15 - xdais_6_10_00_03 I also ran the DVTB application provided in the same package. The DVTB application detects the capture, however the output is black & white (see the chrominance conversion fail messages). This atleast means that DVTB accepts the camera input. However, even though I configrue the DVTB to accept a NTSC input the output of the DVTB is in the PAL (720x576) format, with lines 481 - 576 being junk. ./dvtb-r -s 1.dvs [DVTB-LOG]: dvevmStEngine.c: Codec Engine Runtime initialized setp vpfe width 720 PASS: setp setp vpfe height 480 PASS: setp setp engine name encode PASS: setp setp videnc1 codec h264enc PASS: setp setp videnc1 numframes 300 FAIL: setp func videnc1 -t capture.264 [DVTB-LOG]: dvevmStFuncDispatcher.c: Starting Thread for command <videnc1>PNDG: func [DVTB-LOG]: dvevmStEngine.c: Engine <encode> opened.
