• ffmpeg - over 1000 files into a mp4

  20 octobre 2013, par Fabrizio

  I am using FreeBSD and ffmpeg and I am trying to convert over 1000 files into an mp4. Keep in mind that I am completely NEW to ffmpeg and that in the future I might have up to 3600 images.

  I was thinking that simply executing :

  ffmpeg -i /usr/local/www/tmp/phpFa5LT3/*.jpg -r 2 output.mp4

  would work, but I keep getting

• ffmpeg unable to find encoder 'libvorbis'

  15 juillet 2014, par scientiffic

  I’m unable to transcode a video file to webm because my machine isn’t able to find libvorbis. When I run the following command :

  ffmpeg -y -i /public/uploads/tmp/1382112521-11953-7661/webm_Untitled.mov -vcodec libvpx -acodec libvorbis -s 640x360  -b 1500k -ab 160000 -f webm -g 30 -aspect 1.7777777777777777 /public/uploads/tmp/1382112521-11953-7661/tmpfile.webm

  I get the error

  Unknown encoder 'libvorbis'

  I already have libvorbis installed on my machine, though (When I try "brew install libvorbis, it tells me : Warning : libvorbis-1.3.3 already installed).

  How can I solve this problem ?

  Here is the full log :

  ffmpeg -y -i /public/uploads/tmp/1382112521-11953-7661/webm_Untitled.mov -vcodec libvpx -acodec libvorbis -s 640x360  -b 1500k -ab 160000 -f webm -g 30 -aspect 1.7777777777777777 /public/uploads/tmp/1382112521-11953-7661/tmpfile.webm
