General questions</A> - - <B>Q: What about DVD playing ? - </B>A: Read the CD/DVD section . - - <B>Q: -xy option doesn't work with x11 driver (-vo x11) - </B>A: x11 driver doesn't support scaling, but XF86VidMode support is now - used: you must specify the -vm and the -fs switch, and you're done. - Make sure you have the right Modelines in your XF86Config file, and - try if the DGA driver (and SDL's DGA driver, see RTFM) works for you. - It's much faster. If SDL's DGA works too, use that, it'll be EVEN - faster! - - <B>Q: what is the meaning of numbers in the status line? - </B>A: see: - </B>A: 2.1 V: 2.2 A-V: -0.167 ct: 0.042 57 41% 0% 2.6% 0 - - </B>A: audio position in seconds - - V: video position in seconds - - A-V: audio-video difference in seconds (delay) - - ct: total A-V sync correction done - - frames played (counting from last seek) - - video codec cpu usage in percent (for mpeg it includes video_out too!) - - video_out cpu usage for avi, 0 for mpg (see above) - - audio codec cpu usage in percent - - frames needed to drop to maintain A-V sync - Most of them are for debug purposes, and will be removed soon. - - <B>Q: Why is video_out cpu usage zero (0%) for mpeg files? - </B>A: It's not zero, but it's built in into codec, so can't be measured separated. - You should try to play the file using -vo null and then -vo ... and check - the difference to see video_out speed... - - <B>Q: What's XMMP? (is it XMMS or XMPS but mispelled?) - </B>A: It's a new project, see http://frozenproductions.com for details - - <B>Q: There are error messages about file not found /usr/lib/win32/.... - </B>A: Download & install w32codec.zip from *our* FTP - (avifile's codec package has different DLL set) - - <B>Q: Are there any mailing lists on <B>MPlayer</B>? - </B>A: Yes! See RTFM on how to subscribe them! - - <B>Q: I've found a nasty bug when I tried to play my favourite video!! - Who should I inform? - </B>A: See Appendix <A HREF="bugreports.html">C</A> . - - <B>Q: I have problems playing files with ... codec. Can I use'em? - </B>A: Check http://mplayerhq.hu/MPlayer/DOCS/codecs.html, - if it doesn't contain your codec, read - http://mplayerhq.hu/MPlayer/DOCS/CODECS, and contact us. - - <B>Q: Umm, what is "IdegCounter" ? - </B>A: A mixture of a hungarian and an english word. In english, "Ideg" means - "nerve", and is pronounced as something like "ydaegh" . It was first used - to measure the nervousness of A'rpi, after some (umm) "mystic" disappearance - of CVS code ;) - - <B>Q: LIRC doesn't work, because ... - </B>A: Are you sure you use "mplayer_lirc" instead of "mplayer" ? - - <B>Q: Subtitles are very nice, the most beautiful I've ever seen, but they slow - down the playing! I know it's unlikely... - </B>A: After running ./configure , edit config.h and replace #undef FAST_OSD with - #define FAST_OSD . Then recompile. - - <B>Q: The OSD is flickering! - </B>A: You use a vo driver with single buffering (x11,xv). With xv, - use -double option. - - <B>Q: What exactly is this libavcodec? - </B>A: It's from Gerard Lantau's ffmpeg package (http://ffmpeg.sourceforge.net). - It has C language DivX ;-) and OpenDivX alpha 47 codec. Some benchmarks - showed that its DivX seems to be even faster than DirectShow codec without - preprocessing, and only a few percent slower than ProjectMayo's DivX4 - decoder. It uses YV12 pixel format, so old Voodoo users can use it for YUV. - Also, open the possibility to play DivX on virtually every computer that - has a C compiler. Kinda great stuff, isn't it? - - <B>Q: But configure tells me "Checking for libavcodec ... no"! - </B>A: You need to get libavcodec from FFmpeg's CVS. Read the instructions in - the <A HREF="codecs.html#2.1.2.2">ffmpeg section</A> . - - - <A NAME=5.3>5.3. File playing problems</A> - - <B>Q: ...... works with avifile/aviplay while doesn't with <B>MPlayer</B> - </B>A: <B>MPlayer</B> != avifile - The only common thing between these players is the Win32 DLL loader. - The codecs (dll) sets, syncronization, demultiplexing etc is totaly - different and shouldn't be compared. - If something works with aviplay it doesn't mean that <B>MPlayer</B> should do - it and vice versa. - - <B>Q: audio goes out of sync playing .avi file - </B>A: try with -bps or -nobps option - if still bad, send me (upload to ftp) that file, I'll check. - - <B>Q: Indeo 3.x/4.x movies are viewed upside-down!!!? - </B>A: It's a known bug (really it's a bug/limitation of the DLL codec) - Try if your vo driver supports the -flip switch. - - <B>Q: Indeo 3.x,4.x video doesn't work at 32bpp resolutions (16,24 bpp are ok) - </B>A: It's a known bug (really it's a bug/limitation of the DLL codec) - - <B>Q: I've got '<B>MPlayer</B> interrupted by signal 11' in module audio_setup or - decode_audio. - </B>A: This is highly unlikely, since the mp3lib rewrite. Contact us, it may be - a bug. Possibly it's a damaged file, try with -afm 4 . - - <B>Q: <B>MPlayer</B> exits with something error when using l3codeca.acm - </B>A: Check 'ldd /usr/local/bin/mplayer' output. If it contains - libc.so.6 => /lib/libc.so.6 (0x4???????) - where "?" is any number then it's ok, the error is not here. If it is: - libc.so.6 => /lib/libc.so.6 (0x00??????) - then there is problem with your kernel/libc. Maybe you are using some - security patches (for example Solar Designer's OpenWall patch) which - forces loading libraries to very low addresses. - Because l3codeca.acm is a non-relocatable DLL, it must be loaded to - 0x00400000, we can't change this. You should use non-patched kernel, - or use <B>MPlayer</B>'s -afm 1 option to disable using l3codeca.acm. - - <B>Q: My computer plays M$ DivX AVIs with resolutions ~ 640x300 and stereo mp3 - sound too slow. When I use -nosound switch, everything is ok (but quiet). - </B>A: Those files probably have 48Khz audio, and your soundcard/driver can't play - it correctly. Audio downsampling isn't implemented in <B>MPlayer</B> (yet). - Maybe use the SDL driver, with <B>-ao:sdl</B> +<TD> </TD><TD VALIGN=top>Q:</TD><TD WIDTH=100%><B> +What's the problem with gcc 2.96 ? +</B></TD><TR><TD></TD><TD VALIGN=top>A:</TD><TD> +gcc 2.96 is RedHat's UNOFFICIAL (it can be found only on RedHat sites, or +RedHat distributions) and BUGGY gcc release. gcc 2.96 is TOTALLY +unsupported by <B>MPlayer</B>, because it simply SKIPS MMX codes, it just does +not compile it.

Therefore these formats deserve to die in flames. - Theoretically you can reverse engineer Real codecs built for Linux (they - are available as .so files), but in practice that's really difficult, even - if you know how the compiler used by Real is making assembler code. - As for QuickTime, it's possible to play some old movies and this - capability will be added to mplayer soon, but newer clips are all Sorenson - encoded, and that codec is built-in deep in the QT executable, there's - no way to use it. +<TD></TD><TD VALIGN=top>Q:</TD><TD WIDTH=100%><B> +MPlayer dies with "MPlayer interrupted by signal 4 in module: decode_video". +</B></TD><TR><TD></TD><TD VALIGN=top>A:</TD><TD> +Try running <B>MPlayer</B> on the machine you compiled on.
