This is not possible for xover and anything supporting vidix due to horrible hacks. git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@25248 b3059339-0415-0410-9bf9-f77b7e298cf2

* vo_yuv4mpeg.c, yuv4mpeg (mjpegtools) interface
|
|
*
|
|
* Thrown together by
|
|
* Robert Kesterson <robertk@robertk.com>
|
|
* Based on the pgm output plugin, the rgb2rgb postproc filter, divxdec,
|
|
* and probably others.
|
|
*
|
|
* This is undoubtedly incomplete, inaccurate, or just plain wrong. :-)
|
|
*
|
|
* 2002/06/19 Klaus Stengel <Klaus.Stengel@asamnet.de>
|
|
* - added support for interlaced output
|
|
* Activate by using '-vo yuv4mpeg:interlaced'
|
|
* or '-vo yuv4mpeg:interlaced_bf' if your source has
|
|
* bottom fields first
|
|
* - added some additional checks to catch problems
|
|
*
|
|
* 2002/04/17 Juergen Hammelmann <juergen.hammelmann@gmx.de>
|
|
* - added support for output of subtitles
|
|
* best, if you give option '-osdlevel 0' to mplayer for
|
|
* no watching the seek+timer
