如何使用WinFF将Lagarith .avi视频转换为MP4

Question

我有一堆用Lagarith编解码器编码的.avi视频。我们希望将它们转换为无损.MP4格式，以便可以在html上轻松播放。如果可能，我希望保持视频规格保持不变，只需将视频转换为MP4。

我尝试了WinFF以及一些手动编写的FFmpeg代码[没有任何具体的Lagarith编解码器参考]，但它们都创建了一个无法播放的视频（既不用于Windows播放器也不用于HTML5播放器）。此外，FFmpeg返回像bellow一样的异常。

修改 这是WinFF生成的FFmpeg代码，这段代码给出了以下异常：

"C:\Program Files\WinFF\ffmpeg.exe" -y -i "C:\Desktop\Videos\input.avi" -f mp4 -r 29.97 -vcodec libx264 -preset slow -vf scale=640:480 -b:v 1000k -aspect 4:3 -flags +loop -cmp chroma -b:v 1250k -maxrate 1500k -bufsize 4M -bt 256k -refs 1 -bf 3 -coder 1 -me_method umh -me_range 16 -subq 7 -partitions +parti4x4+parti8x8+partp8x8+partb8x8 -g 250 -keyint_min 25 -level 30 -qmin 10 -qmax 51 -qcomp 0.6 -trellis 2 -sc_threshold 40 -i_qfactor 0.71 -acodec libvo_aacenc -b:a 112k -ar 48000 -ac 2 "C:\Desktop\Videos\output.mp4"

第二次编辑： 以下是我收到的完整例外情况：

kely reason is either wrong type (e.g. a video option with no video streams) or
that it is a private option of some encoder which was not actually used for any
