        : 
        : recordMyDesktop is a desktop session recorder for linux that attempts to be
        : easy to use, yet also effective at it's primary task.
        : 
        : As such, the program is separated in two parts; a simple command line tool that
        : performs the basic tasks of capturing and encoding and an interface that
        : exposes the program functionality in a usable way.

Описание: h264enc is an advanced and powerful interactive menu-driven shell
        : script written for the GNU/Linux operating system which can help you
        : to encode a DVD, a video file, a directory with video files or a (S)VCD
        : to the H.264/MPEG-4 Part 10/AVC video format using the MEncoder encoder
        : from the MPlayer project and the libx264 library. It supports muxing
        : the final encode from AVI to Matroska, from AVI to OGM, from AVI to TS
        : and from AVI to the MP4 container.

Select the Input type [file/dir/dvd/vcd]: file
Provide the Input Video File: out-3.ogv
Provide a name for the Output File [default is H264-30299]: 

Note that you are running out of disk space in
the destination output directory and/or in the
configuration directory of h264enc!

This could be a problem if you want to convert
the final encode to MKV, OGM, TS or to the MP4
container. It is recommended to free up some disk
space or provide a different destination output
directory before continuing with the encoding
process if you intend to do some of the above
tasks!
