FFmpeg use AAC encoder

Question

I am trying to do some video conversion with FFmpeg. I have an mp4 video file (by which I mean, "it has an mp4 extension") that isn't being accepted by the Brasero disk burner, so I'm trying to use FFmpeg to convert it to a file that is actually mp4.

Here's what I'm trying:

ffmpeg -i 5.mp4 Parkford-05.mp4

It tells me that the AAC encoder is experimental and I should add -strict -2 to use it. So I try:

ffmpeg -i 5.mp4 Parkford-05.mp4 -strict -2

and get the same result.

How do I tell it to use the experimental encoder?

Answer 1

Here is what you are looking for:

ffmpeg -i 5.mp4  -strict -2 Parkford-05.mp4

or

ffmpeg -i 5.mp4  -strict experimental Parkford-05.mp4

Additionally, if the file is named "5.mp4" but is not actually an mp4 file, the use of the mp4 extension in the name can cause problems. However, it is not always necessary to provide a file extension; having no file extension does not usually cause problems.

Try renaming the file "5" instead of "5.mp4" and see if that doesn't help.
