-====== ffmpeg2theora ======
-Ffmpeg2theora is not a part of <zapp>ffmpeg</zapp> but an independent frontend
-for converting any format that ffmpeg can read into the free Ogg Vorbis and Ogg
-Theora codecs.
-There may be no real advantage to using ffmpeg2theora rather than just using
-ffmpeg, but it does have an abbreviated set of options since its goal is far
-more focused than the near-infinite possibilities of ffmpeg.
-Tip
-For some video (especially high-res video meant to be dynamically scaled on any
-variety of device with any variety of screen size), you should also consider
-the webm format, which is also free and open source like Theora, directly
-through ffmpeg.
-The command structure is similar, so if you've used ffmpeg or mencoder to
-transcode media then it will all feel very familiar:
-$ ffmpeg2theora input_file.avi -x 1920 -y
--V 21000kbps -A 320kbps -c 2 -H 44100 -o output.ogv
-In other words:
-  $ ffmpeg2theora [input filename] -x
-  [target horizontal pixel count] -y [target vertical
-  pixel count] -V [target bitrate in kbps] -A [audio
-  bit rate] -c [audio channels] -H [audio sample
-  rate in Hz] -o [output filename]
-ffmpeg2theora is available from slackbuilds.org and requires no special compile
-options.
