= Video Format Conversion =

The program {{{ffmpeg}}} has been depricated, use {{{avconv}}} instead.

== Find video information ==
{{{
$ mplayer -vo null -ao null -identify -frames 0 filename.avi
}}}
{{{
$ ffmpeg -i filename.avi
}}}
{{{
$ tcprobe -i filename.avi
}}}

== Find ffmpeg codecs ==
{{{
$ ffmpeg -codecs
}}}

Older version of ffmpeg, use -formats. This also works in newer version, but gives confusing results.

{{{
$ ffmpeg -formats
}}}

== Convert file types ==
This is real simple and only needs one line.

{{{
$ ffmpeg -i filename.ext -ab <audio bitrate> -b <video bitrate> -s <change to what you want ex.320x240> filename.ext
}}}

The two {{{.ext}}} extensions should obviously be different. Also, the new size {{{-s}}} could be whatever you want.<<BR>>
<<BR>>
To keep the size the same but just convert.

{{{
$ ffmpeg -i InputFile.avi -ab <audio bitrate> -b <video bitrate> -vcodec mpeg4 OutputFile.mp4
}}}
