When trying to play most (but not all) Fresh Air streams (wma) at
npr.org, I get very choppy sound. It will play for a second (or less),
drop out for 10-30 seconds, play a second, etc. I used mplayer cvs from
2004-11-18 and it is able to play other content fine. Used from a
plugin and from command line. '-playlist', using esd, using alsa, using
oss, removing codecs.conf, forcing and not forcing libmad all didn't
matter. Got cvs libavcodec as well, didn't matter. I googled, but
couldn't find anything. I will send anything you need. Thanks for a
great app!
Here is the command line:
mplayer -wid 0x1400660 -cache 512 -osdlevel 0 -nojoystick -slave
-nomouseinput
mms://wm.npr.na-central.speedera.net/wm.npr.na-central/fa/20041118_fa_01.wma
/etc/mplayer.conf:
##
## MPlayer config file
##
## This file can be copied to /etc/mplayer.conf and/or ~/.mplayer/config
.
## If both exist, the ~/.mplayer/config's settings override the
## /etc/mplayer.conf ones. And, of course command line overrides all.
## The options are the same as in the command line, but they can be
specified
## more flexibly here. See below.
##
vo=x11, # To specify default video driver (see -vo help
for
# list)
ao=sdl:esd, # To specify default audio driver (see -ao help
for
# list)
fs=no # Enlarges movie window to your desktop's size.
# Used by drivers: all
vm=no # Tries to change to a different videomode
# Used by drivers: dga2, x11, sdl
bpp=0 # Force changing display depth.
# Valid settings are: 0, 15, 16, 24, 32
# may need 'vm=yes' too.
# Used by drivers: fbdev, dga2, svga
zoom=no # Enable software scaling (powerful CPU needed)
# Used by drivers: svga, aalib
double=yes # use double-buffering (recommended for xv with
# SUB/OSD usage)
# x=800 # scale movie to <x> pixels width
# y=600 # scale movie to <y> pixels height
osdlevel=1 # don't display OSD at stratup
monitoraspect=4:3 # standard monitor size, with square pixels
# monitoraspect=16:9 # use this for widescreen monitor! non-square
pixels
cache = 1024 # Disk cache 1 MB
#cache = 8192 # Disk cache 1 MB
##
## Specify your preferred default skin here
## (skins are searched in /usr/share/mplayer/Skin/yourskin
## and ~/.mplayer/Skin/yourskin)
##
skin = default
##
## Multiple languages are available :)
##
## Hungarian igen nem
## English yes no
## German ja nein
## Spanish si no
## Binary 1 0
##
## You can also use spaces and/or tabs.
##
#sound = 1
#nosound = nein
#mixer = /dev/mixer
##
## resample the fonts' alphamap
## 0 plain white fonts
## 0.75 very narrow black outline (default)
## 1 narrow black outline
## 10 bold black outline
##
#ffactor = 0.75
##
## FBdev driver:
# fb = /dev/fb0 # framebuffer device to use
# fbmode = 640x480-120 # use this mode (read from
fb.modes!)
# fbmodeconfig = /etc/fb.modes # the fb.modes file
## VESA and FBdev driver: specify your monitor's timings
##
## (see for example /etc/X11/XF86Config for timings!)
## ** CAUTION! IF YOUR DISPLAY DOESN'T SUPPORT AUTOMATICALLY TURNING OFF
WHEN
## OVERDRIVED (AND EVEN IF IT DOES), THIS MAY CAUSE DAMAGE TO YOUR
DISPLAY!
## WE AREN'T RESPONSIBLE, IT'S YOUR DECISION! **

## k, K : means multiply by 1000
## m, M : means multiply by 1.000.000
##
# monitor_hfreq = 31.5k-50k,70k # horizontal frequency range
# monitor_vfreq = 50-90 # vertical frequency range
# monitor_dotclock = 30M-300M # dotclock (or pixelclock) range
##
## SDL driver
##
# vo = sdl:aalib # use SDL video driver by default
# use "vo = sdl:aalib" or "vo sdl:dga" and so
on,
# for specifying SDL subdrivers
# ao = sdl:esd # use SDL audio driver by default
# use "ao = sdl:esd" to use SDL's ESD driver
# noxv = no # whether to use XVideo hardware acceleration or
not
# forcexv = yes # force XVideo even if not detected
##
## Other (preferred to be default from configfile) switches
##
framedrop=no # drop frames, when not in sync (slow CPU,
videocard,
# etc)
#vfm=ffmpeg # use FFmpeg's libavcodec video codec family
# See "mplayer -vfm help" for all available
codecs
#bps=yes # use this method for playing AVIs (if have
problems,
# try removing this)
# slang= en # DVD : display english subtitles if available
# alang= en # DVD : play english audio tracks if available
## This is the correct way to use "subconfig" type options in the
## configuration file. In the command line you use :
## -aop list=resample:fout=44100 , but here it is :
# aop=list=resample:fout=44100
# From Fedora
# the default mpeg audio decoder is currently broken, let's try libmad
# first:
afm=libmad
# get a default OSD font from fontconfig
#fontconfig = yes
#font = "Sans"
#subfont-text-scale = 3
