Q: Q: Q: Q: Q: 5.2. Q: Q: Q: Q: Q: Q: Q: 5.3. Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: 5.4. Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: 5.5. Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: 5.6. Q: Q: Q: Q: Q: Q: Q: Q: Q: 5.7. Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: 5.1.
Development Q: Q: Q: Q: Q: Q: How do I create a proper patch for MPlayer? A: We made a describing all the necessary details. Please follow the instructions. Q: How do I translate MPlayer to a new language? A: Read the, it should explain everything. You can get further help on the mailing list.
Q: How can I support MPlayer development? A: We are more than happy to accept your hardware and software. They help us in continuously improving MPlayer. Q: How can I become an MPlayer developer?
A: We always welcome coders and documenters. Read the to get a first grasp. Then you should subscribe to the mailing list and start coding. If you want to help out with the documentation, join the mailing list. Q: Why don't you use autoconf/automake? A: We have a modular, handwritten build system. It does a reasonably good job, so why change?
Besides, we dislike the auto. tools, just like.
Compilation and installation Q: Q: Q: Q: Q: Q: Q: Q: Compilation fails with an error and gcc bails out with some cryptic message containing the phrase internal compiler error or unable to find a register to spill. A: You have stumbled over a bug in gcc. Please but not to us. For some reason MPlayer seems to trigger compiler bugs frequently. Nevertheless we cannot fix them and do not add workarounds for compiler bugs to our sources. To avoid this problem, either stick with a compiler version that is known to be reliable and stable, or upgrade frequently.
Q: Are there binary (RPM/Debian) packages of MPlayer? A: See the and section for details. Q: How can I build a 32 bit MPlayer on a 64 bit Athlon? A: Try the following configure options:./configure -target=athlonxp -cc='gcc -m32' -as='as -32' -with-extralibdir=/usr/lib Q: Configure ends with this text, and MPlayer won't compile! Your gcc does not support even i386 for '-march' and '-mcpu' A: Your gcc isn't installed correctly, check the configure.log file for details.

Q: I have a Matrox G200/G400/G450/G550, how do I compile/use the mgavid driver? A: Read the section. Q: During 'make', MPlayer complains about missing X11 libraries.
I don't understand, I do have X11 installed!? But you don't have the X11 development package installed. Or not correctly. It's called XFree86-devel. under Red Hat, and xlibs-dev under Debian Woody, libx11-dev under Debian Sarge.
Also check if the /usr/X11 and /usr/include/X11 symlinks exist (this can be a problem on Mandrake systems). Q: Building on Mac OS 10.3 leads to several link errors A: The link error you're experiencing most likely looks like this: ld: Undefined symbols: LLCStyleInfoCheckForOpenTypeTables referenced from QuartzCore expected to be defined in ApplicationServices LLCStyleInfoGetUserRunFeatures referenced from QuartzCore expected to be defined in ApplicationServices This problem is the result of Apple developers using 10.4 to compile their software and distributing the binaries to 10.3 users via Software Update. The undefined symbols are present in Mac OS 10.4, but not 10.3. One solution can be to downgrade to QuickTime 7.0.1. Here is a better solution.
This will give you a compressed file that contains the QuickTime 7.0.1 Framework and a 10.3.9 QuartzCore Framework. Uncompress the files somewhere that is not in your System folder. Do not install these frameworks into your /System/Library/Frameworks! Using this older copy is only meant to get around link errors!) gunzip. Start - Settings - Configuration - Base Configuration. Set Use Applications position hints to Yes Q: How can I run MPlayer in the background? A: Use: mplayer options filename.
Edit /etc/syconfig/prelink and change PRELINKOPTS=-mR to PRELINKOPTS='-mR -no-exec-shield'. touch /var/lib/misc/prelink.force. /etc/cron.daily/prelink (This relinks all the applications, and it takes quite a while.). execstack -s /path/to/mplayer (This turns off exec-shield for the MPlayer binary.) Q: MPlayer dies with MPlayer interrupted by signal 4 in module: decodevideo A: Don't use MPlayer on a CPU different from the one it was compiled on or recompile with runtime CPU detection (./configure -enable-runtime-cpudetection). Q: When I try to grab from my tuner, it works, but colors are strange. It's OK with other applications.
A: Your card probably reports some colorspaces as supported when in fact it does not support them. Try with YUY2 instead of the default YV12 (see the section). Q: I get very strange percentage values (way too big) while playing files on my notebook. A: It's an effect of the power management / power saving system of your notebook (BIOS, not kernel). Plug the external power connector in before you power on your notebook.
You can also try whether (a SpeedStep interface for Linux) helps you. Q: The audio/video gets totally out of sync when I run MPlayer as root on my notebook. It works normal when i run it as a user.
A: This is again a power management effect (see above). Plug the external power connector in before you power on your notebook or use the -nortc option. Q: While playing a movie it suddenly gets jerky and I get the following message: Badly interleaved AVI file detected - switching to -ni mode. A: Badly interleaved files and -cache don't work well together. Try -nocache. Video/audio driver problems (vo/ao) Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: When I go into fullscreen mode I just get black borders around the image and no real scaling to fullscreen mode. A: Your video output driver does not support scaling in hardware and since scaling in software can be incredibly slow MPlayer does not automatically enable it.
Most likely you are using the x11 instead of the xv video output driver. Try adding -vo xv to the command line or read the to find out about alternative video output drivers. The -zoom option explicitly enables software scaling. Q: I've just installed MPlayer. When I want to open a video file it causes a fatal error: Error opening/initializing the selected videoout (-vo) device.
How can I solve my problem? A: Just change your video output device.
Issue the following command to get a list of available video output drivers: mplayer -vo help After you've chosen the correct video output driver, add it to your configuration file. Add vo = selectedvo to /.mplayer/config and/or vodriver = selectedvo to /.mplayer/gui.conf. Q: I have problems with your window manager and fullscreen xv/xmga/sdl/x11 modes. A: Read the and send us a proper bug report. Also try experimenting with the -fstype option. Q: Audio goes out of sync playing an AVI file. A: Try the -bps or -nobps option.
If it does not improve, read the and upload the file to FTP. Q: My computer plays MS DivX AVIs with resolutions 640x300 and stereo MP3 sound too slow.
When I use the -nosound option, everything is OK (but quiet). A: Your machine is too slow or your sound card driver is broken. Consult the documentation to see if you can improve performance.
Q: How can I use dmix with MPlayer? A: After setting up your you have to use -ao alsa:device=dmix.
Q: I have no sound when playing a video and get error messages similar to this one: AO: oss 44100Hz 2ch Signed 16-bit (Little-Endian) audiosetup: Can't open audio device /dev/dsp: Device or resource busy couldn't open/init audio device - NOSOUND Audio: no sound!!! Start playing. A: Are you running KDE or GNOME with the aRts or ESD sound daemon? Try disabling the sound daemon or use the -ao arts or -ao esd option to make MPlayer use aRts or ESD. You might also be running ALSA without OSS emulation, try loading the ALSA OSS kernel modules or add -ao alsa to your command line to directly use the ALSA audio output driver. Q: When starting MPlayer under KDE I just get a black screen and nothing happens. After about one minute the video starts playing.
A: The KDE aRts sound daemon is blocking the sound device. Either wait until the video starts or disable the aRts daemon in control center. If you want to use aRts sound, specify audio output via our native aRts audio driver ( -ao arts). If it fails or isn't compiled in, try SDL ( -ao sdl) and make sure your SDL can handle aRts sound. Yet another option is to start MPlayer with artsdsp. Q: I have A/V sync problems. Some of my AVIs play fine, but some play with double speed!
A: You have a buggy sound card/driver. Most likely it's fixed at 44100Hz, and you try to play a file which has 22050Hz audio. Try the resample audio filter. Q: When I play this movie I get video-audio desync and/or MPlayer crashes with the following message: DEMUXER: Too many (945 in 8390980 bytes) video packets in the buffer! A: This can have multiple reasons.
Mplayer-dev-eng Real Audio Video Dll Support For Mac
Your CPU and/or video card and/or bus is too slow. MPlayer displays a message if this is the case (and the dropped frames counter goes up fast). If it is an AVI, maybe it has bad interleaving, try the -ni to work around this. Or it may have a bad header, in this case -nobps and/or -mc 0 can help. Your sound driver is buggy. Q: How can I get rid of A/V desynchronization while seeking through RealMedia streams?
A: -mc 0.1 can help. DVD playback Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: What about DVD navigation/menus? A: MPlayer does not support DVD menus due to serious architectural limitations that prevent proper handling of still images and interactive content. If you want to have fancy menus, you will have to use another player like xine, vlc or Ogle. If you want to see DVD navigation in MPlayer you will have to implement it yourself, but be aware that it is a major undertaking.
Q: I can't watch any recent DVDs from Sony Pictures/BMG. A: This is normal; you've been ripped off and sold an intentionally defective disk.
The only way to play these DVDs is to circumvent the bad blocks of the disk by using DVDnav instead of mpdvdkit2. You can do so by compiling MPlayer with DVDnav support and then replacing dvd:// by dvdnav:// on the command line. DVDnav is so far mutually exclusive with mpdvdkit2, so make sure you pass -disable-mpdvdkit to the configure script. Q: What about subtitles? Can MPlayer display them?
Q: How can I set the region code of my DVD-drive? I don't have Windows!
Q: I can't play a DVD, MPlayer hangs or outputs 'Encrypted VOB file!' A: CSS decryption code does not work with some DVD drives unless you set the region code appropriately. See the answer to the previous question.
Q: Do I need to be (setuid) root to be able to play a DVD? However you must have the proper rights on the DVD device entry (in /dev/). Q: Is it possible to play/encode only selected chapters? A: Yes, try the -chapter option. Q: My DVD playback is sluggish! A: Use the -cache option (described in the man page) and try enabling DMA for the DVD drive with the hdparm tool (described in the ). Q: I copied a DVD using vobcopy.
How do I play/encode it from my hard disk? A: Use the -dvd-device option to refer to the directory that contains the files: mplayer dvd://1 -dvd-device /path/to/directory 5.7. Feature requests Q: Q: Q: If MPlayer is paused and I try to seek or press any key at all, MPlayer ceases to be paused. I would like to be able to seek in the paused movie. A: This is very tricky to implement without losing A/V synchronization. All attempts have failed so far, but patches are welcome.
Q: I'd like to seek +/- 1 frame instead of 10 seconds. A: You can step forward one frame by pressing. If the movie was not paused it will be paused afterwards (see the man page for details). Stepping backwards is unlikely to be implemented anytime soon. Encoding Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: Q: How can I encode? A: Read the section. Q: How can I dump a full DVD title into a file?
A: Once you have selected your title, and made sure it plays fine with MPlayer, use the option -dumpstream. For example: mplayer dvd://5 -dumpstream -dumpfile dvddump.vob will dump the 5th title of the DVD into the file dvddump.vob Q: How can I create (S)VCDs automatically? A: Try the mencvcd script from the TOOLS subdirectory. With it you can encode DVDs or other movies to VCD or SVCD format and even burn them directly to CD. Q: How can I create (S)VCDs? A: Newer versions of MEncoder can directly generate MPEG-2 files that can be used as a base to create a VCD or SVCD and are likely to be playable out of the box on all platforms (for example, to share a video from a digital camcorder with your computer-illiterate friends).
Please read for more details. Q: How can I join two video files? A: MPEG files can be concatenated into a single file with luck. For AVI files, you can use MEncoder's multiple file support like this: mencoder -ovc copy -oac copy -o out.avi file1.avi file2.avi This will only work if the files are of the same resolution and use the same codec. You can also try and avimerge (part of the tool set). Q: How can I fix AVI files with a broken index or bad interleaving? A: To avoid having to use -idx to be able to seek in AVI files with a broken index or -ni to play AVI files with bad interleaving, use the command mencoder input.avi -idx -ovc copy -oac copy -o output.avi to copy the video and audio streams into a new AVI file while regenerating the index and correctly interleaving the data.
Of course this cannot fix possible bugs in the video and/or audio streams. Q: How can I fix the aspect ratio of an AVI file?
A: You can do such a thing thanks to MEncoder's -force-avi-aspect option, which overrides the aspect stored in the AVI OpenDML vprp header option. For example: mencoder input.avi -ovc copy -oac copy -o output.avi -force-avi-aspect 4/3 Q: How can I backup and encode a VOB file with a broken beginning? A: The main problem when you want to encode a VOB file which is corrupted is that it will be hard to get an encode with perfect A/V sync. One workaround is to just shave off the corrupted part and encode just the clean part. First you need to find where the clean part starts: mplayer input.vob -sb nbofbytestoskip Then you can create a new file which contains just the clean part: dd if= input.vob of= outputcut.vob skip=1 ibs= nbofbytestoskip Q: I can't encode DVD subtitles into the AVI! A: You have to properly specify the -sid option.
Q: How can I encode only selected chapters from a DVD? A: Use the -chapter option correctly, like: -chapter 5-7. Q: I'm trying to work with 2GB+ files on a VFAT file system. Does it work? A: No, VFAT doesn't support 2GB+ files.
Q: What is the meaning of the numbers on the status line during the encoding process? A: Example: Pos: 264.5s 6612f ( 2%) 7.12fps Trem: 576min 2856mb A-V:0.065 2126:192. Pos: 264.5s time position in the encoded stream 6612f number of video frames encoded ( 2%) portion of the input stream encoded 7.12fps encoding speed Trem: 576min estimated remaining encoding time 2856mb estimated size of the final encode A-V:0.065 current delay between audio and video streams 2126:192 average video bitrate (in Mb/s) and average audio bitrate (in Mb/s) Q: Why is the recommended bitrate printed by MEncoder negative?
A: Because the bitrate you encoded the audio with is too large to fit the movie on any CD. Check if you have libmp3lame installed properly.
Q: I can't encode an ASF file to AVI/MPEG-4 (DivX) because it uses 1000 fps. A: Since ASF uses variable framerate but AVI uses a fixed one, you have to set it by hand with the -ofps option. Q: How can I put subtitles in the output file? A: Just pass the -sub (or -sid, respectively) option to MEncoder. Q: How do I encode only sound from a music video? A: It's not possible directly, but you can try this (note the & at the end of mplayer command): mkfifo encode mplayer -ao pcm -aofile encode dvd://1 & lame youropts encode music.mp3 rm encode This allows you to use any encoder, not only LAME, just replace lame with your favorite audio encoder in the above command. Q: Why do third-party players fail to play MPEG-4 movies encoded by MEncoder versions later than 1.0pre7?
A: libavcodec, the native MPEG-4 encoding library usually shipped with MEncoder, used to set the FourCC to 'DIVX' when encoding MPEG-4 videos (the FourCC is an AVI tag to identify the software used to encode and the intended software to use for decoding the video). This led many people to think that libavcodec was a DivX encoding library, when in fact it is a completely different MPEG-4 encoding library which implements the MPEG-4 standard much better than DivX does. Therefore, the new default FourCC used by libavcodec is 'FMP4', but you may override this behavior using MEncoder's -ffourcc option.
You may also change the FourCC of existing files in the same way: mencoder input.avi -o output.avi -ffourcc XVID Note that this will set the FourCC to XVID rather than DIVX. This is recommended as DIVX FourCC means DivX4, which is a very basic MPEG-4 codec, whereas DX50 and XVID both mean full MPEG-4 (ASP). Therefore, if you change the FourCC to DIVX, some bad software or hardware players may choke on some advanced features that libavcodec supports, but DivX doesn't; on the other hand XviD is closer to libavcodec in terms of functionality, and is supported by all decent players. Q: How can I encode an audio only file?

A: Use aconvert from the TOOLS subdirectory in the MPlayer source tree. Q: How can I play subtitles embedded in AVI?
A: Use avisubdump.c from the TOOLS subdirectory or read. Q: MPlayer won't. A: Have a look at the TOOLS subdirectory for a collection of random scripts and hacks. TOOLS/README contains documentation.
MPlayer Features MPlayer is a movie player which runs on many systems (see the documentation). It plays most MPEG/VOB, AVI, Ogg/OGM, VIVO, ASF/WMA/WMV, QT/MOV/MP4, RealMedia, Matroska, NuppelVideo, FLI, YUV4MPEG, FILM, RoQ, PVA files, supported by many native, XAnim, and Win32 DLL codecs.
You can watch VideoCD, SVCD, DVD, 3ivx, DivX 3/4/5, WMV and even H.264 movies. Another great feature of MPlayer is the wide range of supported output drivers. It works with X11, Xv, DGA, OpenGL, SVGAlib, fbdev, AAlib, DirectFB, but you can use GGI, SDL (and this way all their drivers), VESA (on every VESA compatible card, even without X11!) and some low level card-specific drivers (for Matrox, 3Dfx and ATI), too! Most of them support software or hardware scaling, so you can enjoy movies in fullscreen.
MPlayer supports displaying through some hardware MPEG decoder boards, such as the Siemens DVB, DXR2 and DXR3/Hollywood+. MPlayer has an onscreen display (OSD) for status information, nice big antialiased shaded subtitles and visual feedback for keyboard controls. European/ISO 8859-1,2 (Hungarian, English, Czech, etc), Cyrillic and Korean fonts are supported along with 12 subtitle formats (MicroDVD, SubRip, OGM, SubViewer, Sami, VPlayer, RT, SSA, AQTitle, JACOsub, PJS and our own: MPsub). DVD subtitles (SPU streams, VOBsub and Closed Captions) are supported as well. MPlayer is available under the.
