All righty.
So....what I did:
I uninstalled the mplayer-version apt-get installed for me, what means that I did the following:
rpm -e mplayer-gui-1.0pre4-3
rpm -e mplayer-common-1.0pre4-3
rpm -e mplayer-skin-default-1.0-2
what I did next was:
--> I downloaded the current mplayer-version-source from mplayerhq.hu:
I configured the makefile using:
--> ./configure --enable-gui --enable-runtime-cpudetection
everything worked fine...so I typed in "make" and after success I typed in "make install"
finally everything worked fine
...
I still had to install a skin and the fonts and so I did
After this procedure I started the gmplayer and tried to play a video file and then the error message appeared.
--> error opening/initializing video_out (-vo) device
okay...pretty unmotivating.
Now I tried if the mplayer works without gui and it worked fine.
mplayer told me that he uses the Planar YV12 vo-device by:
-->VDec: vo config request - 480 x 480 (preferred csp: Planar YV12)
-->VDec: using Planar YV12 as output csp (no 0)
I tried to config this output device in the mplayer config file, like:
enable_audio_equ = "no"
--> vo_driver = "YV12"
vo_panscan = "0.000000"
vo_doublebuffering = "no"
vo_direct_render = "no"
v_framedrop = "0"
v_flip = "-1"
v_ni = "no"
v_idx = "-1"
vf_pp = "no"
vf_autoq = "0"
vf_lavc = "no"
ao_volnorm = "no"
ao_surround = "no"
ao_extra_stereo = "no"
ao_extra_stereo_coefficient = "1.000000"
ao_oss_mixer = "/dev/mixer"
ao_oss_device = "/dev/dsp"
osd_level = "1"
sub_auto_load = "yes"
sub_unicode = "no"
sub_pos = "100"
sub_overlap = "no"
font_factor = "0.750000"
font_text_scale = "5.000000"
font_osd_scale = "6.000000"
font_blur = "2.000000"
font_outline = "2.000000"
font_autoscale = "3"
cache = "yes"
cache_size = "8192"
playbar = "yes"
load_fullscreen = "no"
show_videowin = "yes"
stopxscreensaver = "no"
autosync = "no"
autosync_size = "0"
gui_skin = "neutron"
gui_save_pos = "yes"
gui_main_pos_x = "708"
gui_main_pos_y = "425"
gui_video_out_pos_x = "406"
gui_video_out_pos_y = "74"
....but the error message still appears.
What is wrong with the mplayer gui?
Thanks for any suggestions.
