用的是EVM-DM368
Lewis Lee：
dvsdk4.02?tvp5146工作了吗
kai chen2：
回复 Lewis Lee:
对 是dvsdk4.02 以log信息来看tp5146是工作了！
Lewis Lee：
回复 kai chen2:
你用示波器看看，我感觉是视频采集芯片的问题，你再仔细看看。
我原先碰见过类似的问题，就是视频采集芯片根本没工作。
kai chen2：
回复 Lewis Lee:
测了下，是在工作的

回复 kai chen2:
我也出现了次情况，不过sensor是mt9p031；目前还没解决；
fang zhang：
解码显示线程都已经正常跑起来了。是不是视频显示被OSD挡住了，所以你看不到视频？ 尝试修改一下OSD配置。
peng zhang5：
./encode -v test.264 -y2 -o 参数后面加个 -o 试试
peng zhang5：
对了 你的视频源是什么 是composite口进来的 还是Component（分量） 还是Component？
