我在Ubuntu 11.10上运行，打算编译HTTP Live Video Stream Segment and Distrbutor。
按照here的说明，我设法相应地设置FFMpeg。但是当我尝试配置它时遇到了错误。
gcc -v -Wall -g live_segmenter.c -o live_segmenter \ -lavformat -lavcodec -lavutil -lvorbis -ltheora \ -lbz2 -lm -lz -lfaac -lmp3lame \ -I / tmp / old_ffmpeg / include \ -L / TMP / old_ffmpeg / lib中
以下是错误消息：

看起来有些库缺失，但我不知道它是什么。
如何解决此问题 - 已更新
只需添加-lva即可
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 / include \ -L / TMP / old_ffmpeg / lib中
答案 0 :(得分：6)
你缺少了libva，你也不需要它。您可以将--disable-vaapi添加到ffmpeg配置中。否则，您需要将-lva添加到LDFLAGS。
