请问怎样把CIF大小的yuyv格式视频和WAV音频交织成一个AVI文件?
我使用ffmpeg提示未知格式错误:
$ ffmpeg -i foobar1.wav -s cif recVideo_ch_1.yuyv out.avi
libavutil 49.10. 0 / 49.10. 0
libavcodec 51.71. 0 / 51.71. 0
libavformat 52.22. 1 / 52.22. 1
libavdevice 52. 1. 0 / 52. 1. 0
libavfilter 0. 1. 0 / 0. 1. 0
libswscale 0. 6. 1 / 0. 6. 1
libpostproc 51. 2. 0 / 51. 2. 0
built on Sep 28 2008 16:03:53, gcc: 4.1.2 20070925 (Red Hat 4.1.2-33)

是还要装什么库吗?还是应该指定其它选项,找了下没找到。 |
