convert from avi to mp4 using ffmpeg
Solution 1
Old, but this post comes up tops in searches so...
ffmpeg should easily convert from avi to mp4 without re-encoding. (Do not specify new codecs!)
ffmpeg -i input.avi -c:v copy -c:a copy OUTPUT.mp4
Should also mention that batch conversions run most reliably when the script contains static data with each ffmpeg call on a new line (as opposed to having the script generate each call dynamically using variables).
Solution 2
I would suggest you use the latest version of ffmpeg. You don't need to download extra dlls.
Use libvo_aacenc
instead of libfaac
-crf 22
is high use lower say -crf 19
As far my experience I would use
ffmpeg -i input.avi -c:v libx264 -preset slow -crf 19 -c:a libvo_aacenc -b:a 128k
Solution 3
code to avi to mp4.ffmpeg provides the best solution
ffmpeg -i input.avi -strict -2 output.mp4

The conversion of video is completed but the video codec and audio codec isn't valid thus it fails to play to play using video tag in

enhzflep over 10 yearsFind a video that does work, then encode your videos with the same codecs, simples. To get info, use the following cmd
ffmpeg -i mymovie.avi
, wheremymovie.avi
is replaced with the name of your video.

llogan about 5 yearsThe question asker already tried that (besides properly omitting the unneeded
-strict -2
). What does your answer do any differently?
