实际上问题的一部分来自玩家 - 这么弱的问题

使用ffmpeg-3.3.2-1.mga6.tainted的命令：

ffmpeg -i dscn0146.avi -pix_fmt yuv422p -s 640x480 dscn0146_hq.ogv -y

输入元数据：

Guessed Channel Layout for Input Stream #0.1 : mono
Input #0, avi, from 'dscn0146.avi':
  Metadata:
    encoder         : 
    maker           : NIKON

    Stream #0:1: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 22050 Hz, mono, s16, 352 kb/s
Stream mapping:
  Stream #0:0 -> #0:0 (mjpeg (native) -> theora (libtheora))
  Stream #0:1 -> #0:1 (pcm_s16le (native) -> vorbis (libvorbis))

正常处理，但会发出警告：

[swscaler @ 0xd3c3a0] deprecated pixel format used, make sure you did set range correctly

输出元数据：
