谢谢,不过我使用下面的命令之后,视频没有翻转呀:
- amro@home:~$ mencoder /home/amro/vedio/MOV01460.MPG -vf rotate=1 -oac copy -ovc copy -o a.mpg
复制代码
-ovc copy 是直接把视频数据复制到输出,所以翻转无效。视频无损翻转我就不知道了。- Available codecs:
- copy - frame copy, without re-encoding. Doesn't work with filters.
- frameno - special audio-only file for 3-pass encoding, see DOCS.
- raw - uncompressed video. Use fourcc option to set format explicitly.
- nuv - nuppel video
- lavc - libavcodec codecs - best quality!
- vfw - VfW DLLs, read DOCS/HTML/en/encoding-guide.html.
- qtvideo - QuickTime DLLs, currently only SVQ1/3 are supported.
- libdv - DV encoding with libdv v0.9.5
- xvid - XviD encoding
- x264 - H.264 encoding
