I'm trying build pjsip from source with video support by gcc on ubuntu. After i success full run ./configure and make dep, i run make and i have error below:
我正在尝试使用gcc在ubuntu上的视频支持从源代码构建pjsip。在我成功地完成了全部运行后。/配置并制作dep，我运行make，我在下面有错误:

Looks like most of errors you are seeing are rooted in the fact enum CodecID is not found. Not sure where it might be in your source, but this commit discusses renaming it to AVCodecID. Are you sure you have an up-to-date source?
看起来您看到的大多数错误都植根于enum CodecID没有被发现这一事实。不确定它在源文件中的位置，但是这个提交讨论将它重命名为AVCodecID。你确定你有最新的资料来源吗?
