[MPlayer-users] DirectFB FAQ

[Jiri Svoboda]

Hi,
because there are some repeating questions about -vo directfb I'll try to
summarize them and also I'll try give some hints.

At first I'd like to suggest to all users to use latest MPlayer and DirectFB
- preferably from CVS. Some issues from previous versions are already fixed!
If You seek for more DOCS there are mailing lists focused on directfb
located at www.directfb.org.


Small FAQ:
Q1: Are there any command line switches for -vo directfb not listed in man
page?
A: YES - vo directfb command line help (can be shown by -vo directfb:help):

                       Example: mplayer -vo
directfb:layer=1:buffermode=single

                       Options (use 'no' prefix to disable):
                         input  Use DirectFB for keyboard input
                       Other options:
                         layer=n
                           n=0..xx   Use layer with id n for output
(0=primary)
                         buffermode=(single|double|triple)
                           single   Use single buffering
                           double   Use double buffering
                           triple   Use triple buffering
                         fieldparity=(top|bottom)
                           top      Top field first
                           bottom   Bottom field first

      Note: Most of the switches are same as for -vo dfbmga

Q3: I'm getting tearing or flashing of movie or subtitles
A: Did You try to set double or triple buffering (-vo directfb
buffermode=double|triple)?
    Did You try to use -double switch of mplayer?

Q4: I'm getting sound, but on screen only progress bar is shown.
A: Should be fixed in CVS (and latest pre version).
   In older versions try to use -dr switch. This usually solves the problem.
   And also improves performance.

Q5: I'm getting black borders around movie and I'd like to use them for
subtitles
A:  Read mplayer documentation with focus on -vop expand option.

Q6: Somethink else wrong....
A: As a starting point try to run example & test programs coming with
directfb library.
    This will check basic operations of directfb on your hardware. In cause
of troubles
    there is directfb-users mailing list (look at www.directfb.org).
    If test programs work OK and mplayer still does not work is a right
time to read

    and follow instructions here.
