I'm using ArchLinux and when I run vlc or mplayer, I used to get the error Failed to open VDPAU backend libvdpau_nouveau.so: cannot open shared object file: No such file or directory This doesn't seem to cause any error as far as video playback is concerned, but I want to know the reason for this problem. I referred to this post in UbuntuForums and one of the suggestions to solve the problem was to install nouveau-fw. Looking at the installed files by the nouveau-fw package, I couldn't find libvdpau_nouveau.so at all in the list, but surprisingly mplayer stopped showing the error after installing the package. But vlc still continues to show the error. The only other solution given in the post was to install official nvidia drivers. I'm hoping to avoid this and just use the open-source drivers. Hoping someone can provide a solution to this.

This -geometry 256x144+1095+600 work to show video in rigth bottom: mplayer -ontop -noborder -geometry 256x144+1095+600 -loop 0 -idle -fixed-vo -msglevel all=-1 2>/dev/null video.mp4 But this one (-vo caca) always stay in same position with same width and height regardless of -geometry any_value: mplayer -vo caca -ontop -noborder -geometry 256x144+1095+600 -loop 0 -idle -fixed-vo -msglevel all=-1 2>/dev/null video.mp4 My ultimate goal is display it in virtual console, so i wanted to know the equivalent format of -geometry for -vo caca. (It could be nice to know -vo fbdev too :)

I have as my main media/video player my own (built from source by myself, including all the necessary libraries) mplayer However, one of the problems that I have with it, it's his low relative performance when compared to the system default media player (totem) and with some customized version of mplayer that runs in another linux. For instance, a 1280x720 video (scaled to 1024x768), used between 65-89% of cpu use in a few minutes of observation. This with mplayer automatically re-scaling it to 1024x768. Totem has a greater range of cpu utilization (like 34 to 86%) when also re-scaling the video. Perhaps, its because it does not play it smoothly (it has fairly frequent very small fractions of time where the video stops playing). The video is not really playable on Totem when compared with Mplayer, despite lower cpu utilization. However, this was for a HD video. For a 640x360 scaled to 1024x768, mplayer used mainly 35 to 40% of cpu use in slow moving scenes and between high 30s to about 45-46% in faster scenes. Totem on other hand uses something like 12-20% cpu in the slow scenes and from a bit less than twenty to about 30% in the faster scenes. The mplayer of the other linux is by far the faster of the three. On the 640x360 video, it uses around 8.5-9.0% of cpu use in the slower scenes, with peaks around 13%. On the faster scenes, it usually goes from low 10s to around 16-17%, perhaps a bit more in a very few selected moments. Xorg use seems to be considerably less, around 3.3 to 4% most of time, against 6-7%, perhaps 8% of the xorg on the other OS So my goal is to bring my mplayer performance close to mplayer from the other OS (perhaps xorg performance too) Feel to make any questions about my system.

I want to use mplayer command line to play music files in the terminal and keep the output messages quiet only except for audio timestamp. Only keep the last line A: 133.5 (02:13.4) of 347.1 (05:47.0) 0. in the below example (of course 02:13.4/05:47.0 format would be better). Is there any way to get that? Thanks.

New to this forum but have been a Linux user for over 20 years. I support an older OpenSuse 12.2 box that has one of the WinTV Hauppauge FM tuner boards. MPlayer4.1 runs fine on the console for audio and video. I would like to run the same for the FM tuner in the card. Been looking at the Man pages for usage such as: mplayer radio://[channel|frequency][/capture] [options] I.e. mplayer -radio driver=v4l radio://104.4 each time I get: MPlayer 1.0rc4-4.1.2 (C) 2000-2010 MPlayer Team Playing radio://104.4. [radio] Unknown driver name: v4l Failed to open radio://104.4. Exiting... (End of file) Has anyone any luck running FM radio from MPlayer on the Hauppauge cards in the past? Seems like it is asking for the driver type each time. Thanks Steve

Wanting to run a video as my screensaver, I ran into problems configuring it appropriately. I am summarizing the solution here in Q&A format.

I'm trying to open mplayer to play video without **any** terminal output using this: mplayer -msglevel all=-1 /path/to/video also: mplayer -really-quiet /path/to/video but it doesn't make it completely silent! and these are printed to output: [flv @ 0x9a5d100]Estimating duration from bitrate, this may be inaccurate [ass] Init [ass] Updating font cache How can I make mplayer completely silent? Thanks

It's supposed to start and control an *mplayer* process. The webserver starts mplayer with -slave -input file=/srv/mplayer.fifo. (So mplayer reads and executes commands from that file.) In order to skip to the next song, one of the webserver scripts writes pt_skip 1 to /srv/mplayer.fifo. This indeed works when mplayer was run from command line. But when started from lighttpd, mplayer does not read commands from /srv/mplayer.fifo. I don't understand why. Here's what I did: Setup $ mkfifo /srv/mplayer.fifo $ chmod o+w /srv/mplayer.fifo $ ls -l /srv/mplayer.fifo prw-r--rw- 1 root root 0 Aug 7 12:11 /srv/mplayer.fifo Test (ran from command line) $ sudo -u www-data mplayer -ao alsa -slave -input file=/srv/mplayer.fifo -playlist /srv/list -shuffle $ lsof /srv/mplayer.fifo COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME mplayer 21059 www-data 4u FIFO 179,2 0t0 2359331 /srv/mplayer.fifo $ ps aux | grep mplayer root 21058 0.0 0.2 4680 2400 pts/0 S+ 12:13 0:00 sudo -u www-data mplayer -ao alsa -slave -input file=/srv/mplayer.fifo -playlist /srv/list -shuffle www-data 21059 11.6 3.1 127928 30008 pts/0 SL+ 12:13 0:01 mplayer -ao alsa -slave -input file=/srv/mplayer.fifo -playlist /srv/list -shuffle That's like expected. But if I run mplayer from lighttpd ... $ cat /var/www/html/play #!/usr/bin/bash mplayer -ao alsa -slave -input file=/srv/mplayer.fifo -playlist /srv/list -shuffle & ... **it starts mplayer**, but the mplayer instance is not reading from /srv/mplayer.fifo. lsof doesn't produce any output: $ lsof /srv/mplayer.fifo $ ps aux | grep mplayer www-data 21177 15.3 3.1 128212 29744 ? SL 12:30 0:01 mplayer -ao alsa -slave -input file=/srv/mplayer.fifo -playlist /srv/list -shuffle I can also see mplayer is not reading from the pipe, because writing to it blocks. The mplayer logs don't show anything unusual. Do you have an idea why mplayer doesn't read from the named pipe when run from lighttpd?

I am using the "-vo caca" option in order to be able to play a video in the terminal. However, mplayer is opening up a window in which the video runs. Is there any way to make it play in the console window (to have it filled)? I am using Linux Mint 16.

Why doesn't this work? cat /dev/video1 | mplayer - If I could get that to work, then I could play & record video at the same time using 'tee' to feed mplayer and mencoder. I want to play live video (from /dev/video1:input=1:norm=NTSC) and record it at the same time without introducing lag. mplayer plays the video fine (no noticeable lag). mencoder records it fine. But I can't figure out how to "tee" the output from /dev/video so that I can feed it to both at the same time. (I know ways to encode it, then immediately play the encoded video, but that introduces too much lag). If mplayer and mencoder would read from stdin, then I could use 'tee' to solve this. How can I do it? [BTW, I'd be happy with ANY solution that plays & records at the same time, as long as it doesn't add lag - I'm not wedded to mplayer. But encoding first and then playing adds lag.]

In Restart mplayer stream process on loss of internet connection -> use while true an answer is given to restart an external command of a shell script - mplayer - after a connection loss. One commentator also mentions that this solution does avoid high cpu usage - in contrast to this answer: Restart mplayer stream process on loss of internet connection -> use -loop 0 I want to extend this script record.sh that calls mplayer as background job via '&' so that it is also inert against internet connection losses or router reconnects. **As I am a beginner in shell scripting, I have difficulties to get a solution that uses something like** while true do mplayer http://YOURSTREAMHERE:8000/playlist.m3u -cache 1024 sleep 2 done **in the context of that record.sh script (which calls mplayer as a background task via &).** **How would a modified record.sh script look like that is inert to connection losses and does not use much CPU?**

I'm using mplayer version 1.4-11. When trying to play these (audio-only) kind of files, MPlayer gives the error message "Cannot find codec for audio format 0x7375704F." Other media players like vlc have no problem playing them. The supported codec [list](http://www.mplayerhq.hu/DOCS/codecs-status.html) on the MPlayer website says it supports the similar audio format "0x7375706F" with codec names "FFmpeg opus" and "FFmpeg libopus". MPlayer can successfully play opus audio files with an .opus extension or inside an .mkv file, and ffplay (the ffmpeg player utility) can play these mp4 files without a problem. Here's an example command for creating this sort of file (use any audio file you have laying around):

ffmpeg -i myaudio.mp3 -acodec libopus -y test.mp4

Everything indicates MPlayer should have no problem playing this files, and yet it it complains about the audio format being unsupported. Why?

I have a program that's generating audio and I can't get mplayer to play it. I'm doing ./myprogram | mplayer - -cache 1024 -cache-min 30 -noconsolecontrols And I get the message Cache fill: X% (Y bytes) X goes up to the specified cache-min value (but not past it) and then it keeps printing the error message: Cache not filling, consider increasing -cache and/or -cache-min! I tried some other values for cache and cache-min but none of them worked. Of course, there is a possibility that my program is somehow at fault.
