[SOLVED] ffmpeg says: Unknown encoder 'libvo_aacenc

Hi to everyone!

I recently get a video to edit but i need to convert from .MOV to .mp4.
I use winff to convert the videos but when i try to convert i get the message: Unknown encoder 'libvo_aacenc.
I use ffmpeg-full from aur and ffmpeg0.10, ffmpeg2.8, ffmpeg-compat-54 and ffmpeg-compat-54.

The output from the terminal of winff:

And I not know what else can I do.

Any solution?

Re: [SOLVED] ffmpeg says: Unknown encoder 'libvo_aacenc

try this from command line

ffmpeg -i /path/to/inputfile.MOV /path/to/output.mp4 

Note: the problem you are facing is mentioned on ffmpeg page of arch-wiki, you may try changing "_" to "-" or vice-versa.

I'll be nice and pass on the link: https://wiki.archlinux.org/index.php/FFmpeg

Good luck!

Re: [SOLVED] ffmpeg says: Unknown encoder 'libvo_aacenc

libvo_aacenc has been removed from ffmpeg. It was a crappy encoder anyway. Use libfdk-aac, that one's the best. However, you'll need to compile your own ffmpeg to enable libfdk-aac support. Or you use the ffmpeg native aac encoder, it's quite good nowadays.

Re: [SOLVED] ffmpeg says: Unknown encoder 'libvo_aacenc

changing Container

 ffmpeg -i "File.mov" -acodec copy  -vcodec copy "File.mp4"

changing Container /Audio (again) to AAC (mp4a to mp4)

ffmpeg -i File.mov -acodec aac -aq 128 -strict -2 -vcodec copy File.mp4

Re: [SOLVED] ffmpeg says: Unknown encoder 'libvo_aacenc

-strict -2

Don't need that anymore with native aac encoder.

ffmpeg -i file.mov -c:a aac -b:a 128k -c:v copy file.mp4

These gave me about the same sound quality/file size

ffmpeg -t 00:00:30 -i file.mp4 -vn -c:a aac -b:a 128k outfixed.m4a

ffmpeg -t 00:00:30 -i file.mp4 -vn -c:a aac -q:a 1 outvar.m4a
