TMX320DM365 Digital Video Evaluation 板子采集标清问题



bootargs=console=ttyS0,115200n8 noinitrd rw ip=dhcp root=/dev/nfs nfsroot=192.168.1.88:/home/person/workdir/filesys,nolock mem=60M video=davincifb:vid0=OFF:vid1=OFF:osd0=720x576x16,4050K dm365_imp.oper_mode=0 davinci_capture.device_type=1

这个是bootargs参数,

摄像头是输出vbs pal和ntsc视频的,接在了开发板的composit输入端,

通过encode -y 2 -I 1 -v test.264 进行捕捉视频

结果提示Error: Failed to create capture device. Is video input connected?

摄像头已经过测试没有问题,

DVSDK4.02的环境,谁可以解答下,谢谢
