当我尝试运行一些自定义节点来处理一些.avi视频时,我有这样的错误:我猜这个错误与opencv有关,我已经尝试了所有的sloutions,甚至重新编译了带有FFMPEG标志的vision_opencv,并且将urgraded ffmped与--enable-shared --enable-gpl --enable-swscale,但仍然没有运气。

我不能继续我的项目,直到我解决这个问题,我已经浪费了10多个小时才解决这个问题,所以如果你们想到任何解决方案,我会很高兴尝试一下。
答案 0 :(得分:0)
这是一个ffmpeg错误/功能:并非所有转换都会加速。在编译我自己的ffmepg 0.6.2或0.7 rc1时,这些警告消失了(Ubuntu版似乎有它们)。不确定要使用的标志。
