TI中文支持网请问老师，我先将根文件系统带的那个dm816x_1080p_demo.264用命令./decode_a8host_debug.xv5T -i ../data/videos/dm816x_1080p_demo.264 -w 1920 -h 1080 -o sample.yuv -c h264转换成sample.yuv这个文件后，再用命令./display_a8host_debug.xv5T -i ./sample.yuv -d 2 想用电视播放出来，是通过SD接到电视的AV上，结果却在电视显示雪花，请问这可能是什么原因，是不是需要配置什么地方或修改源代码才行啊？？？？

用的是ezsdk的，在uboot里面我设置了启动参数setenv bootargs 'console=ttyO2,115200n8 notifyk.vpssm3_sva=0xBF900000 ti816xfb.vram=0:16M earlyprintk root=/dev/nfs nfsroot=192.168.1.101:/home/zhouyun/ezsdk/filesystem/rootfs,nolock rw mem=128M vram=16M'
但我发现在启动的最后有这样一些错误提示：

上面的发现了fb相关的错误，不知道是不是有什么影响？
