无法编译 HTTP-Live-Video-Stream-Segmenter-and-Distributor

Question

我在 Ubuntu 11.10 上运行，打算编译 HTTP Live Video Stream Segment and Distrbutor。

按照here 的指示，我设法相应地设置了FFMpeg。但是当我尝试配置它时遇到了这个错误。

gcc -v -Wall -g live_segmenter.c -o live_segmenter \ -lavformat -lavcodec -lavutil -lvorbis -ltheora\ -lbz2 -lm -lz -lfaac -lmp3lame \ -I/tmp/old_ffmpeg/包括\ -L/tmp/old_ffmpeg/lib

以下是错误信息：

似乎缺少一些库，但我不知道它是什么。

如何解决这个问题 - 已更新

只要加上 -lva 就可以了

gcc -v -Wall -g live_segmenter.c -o live_segmenter \ -lavformat -lavcodec -lavutil -lvorbis -ltheora\ -lbz2 -lm -lz -lfaac -lmp3lame -lva\ -I/tmp/old_ffmpeg/包括\ -L/tmp/old_ffmpeg/lib

Answer 1

您缺少 libva，而且您也不需要它。您可以将 --disable-vaapi 添加到 ffmpeg 配置中。否则，您需要将 -lva 添加到您的 LDFLAGS。
