gmplayer 错误问题

Posted 11 months, 1 week ago at 11:32 am. 0 comments

错误信息 Error opening/initializing the selected video_out(-vo) device!

如果是在终端中敲命令的话

mplayer -vo x11 *.asf

如果用skin的话(必须保证有skin)

修改~.mplayer/gui.conf

找到相关选项,将其该为

vo_driver = “x11″

运行gmplayer

错误信息 Requested audio codec family [mp3] (afm=mp3lib) not available. enable it at compilation

# 開啟 Mplayer
# 在 Mplayer 上按右鍵 選 Preferences
# 切換到Codecs & Demuxer
# 找到 Audio codec family 選擇”FFmpeg/libavcodec audio decoders
# 按OK 重启 gmplayer

修復 Try adding “echo 1024 > /proc/sys/dev/rtc/max-user-freq” to your system startup scripts. 的方法有下列三種:

* echo 1024 > /proc/sys/dev/rtc/max-user-freq
* sysctl dev/rtc/max-user-freq=1024
* /etc/sysctl.conf 加入 dev/rtc/max-user-freq=1024

加了這個後, 若聲音會不同步, 建議就拿掉, 不然就在 mplayer 的 script 加入 -autosync 30 的參數

附上我的 ~/.mplayer/gui.conf 文件内容

enable_audio_equ = “no”
vo_driver = “x11″
vo_panscan = “0.000000″

ubuntu 下让 totem 播放 rmvb

Posted 11 months, 1 week ago at 11:32 am. 0 comments

让 ubuntu 下 totem 播放 rmvb，步骤如下：

安装编码器

wget -c -P /tmp/ http://www.debian-multimedia.org/pool/main/w/w32codecs/w32codecs_20061022-0.0_i386.deb
wget -c -P /tmp/ http://www.debian-multimedia.org/pool/main/libd/libdvdcss/libdvdcss2_1.2.9-0.0_i386.deb
sudo dpkg -i /tmp/w32codecs_20061022-0.0_i386.deb /tmp/libdvdcss2_1.2.9-0.0_i386.deb

安装 totem-xine

sudo apt-get install totem-xine libxine-extracodecs

这时候播放 rmvb 没有声音！

gksudo gedit ~/.xine/catalog.cache

找到 xineplug_decode_real_audio.so，把 decoder_priority=5 改为 decoder_priority=10。（也就是把 real 解码器的级别提前）

这样就有声音了。类似的，当 totem 播放 wmv 有问题时，也可以适当提高 xineplug_decode_w32dll.so 的级别为 7。
