status line displays pts values in dts order
by Clemens Ladisch 31 Jan '07

31 Jan '07

When playing a .nut file with reordered frames, the time position shown in mplayer's status line is wrong - it doesn't show the time of the currently displayed frame but the pts values of the frames in decoding order. This means that the displayed time value jumps forward and back, and that the A-V delay comes out wrong. (The playback itself is OK.) Below is an example output (H.264 with bframes=16 and b_pyramid=1) (reordered_pts.nut and full output uploaded to /incoming): $ mplayer reordered_pts.nut MPlayer dev-SVN-r22076-3.3.4 (C) 2000-2007 MPlayer Team [...] Playing reordered_pts.nut. libnut file format detected. seeking -12 SEEK_END seeking 309425 SEEK_SET NUT index read successfully, 10 syncpoints seeking 733 SEEK_SET VIDEO: [H264] 336x272 0bpp 25.000 fps 0.0 kbps ( 0.0 kbyte/s) [...] ========================================================================== Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264) ========================================================================== ========================================================================== Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding) FAAD: compressed input bitrate missing, assuming 128kbit/s!

[BUG] r7617 in livavformat breaks MPlayer compilation
by Vladimir Voroshilov 22 Jan '07

22 Jan '07

r7616 unconditionally enables by removing "no longer needed #ifdefs" at least seven demuxers (dc1394,dv1394,ogg, etc) regardless of required libraries availability. This breaks MPlayer compilation with error like "libdc1394/dc1394_control.h: no such file or directory" Temporary solution: ./configure --disable-demuxer=dc1394_demuxer --disable-demuxer=dv1394_demuxer 2diego: ./configure update needed (autodetection, at this point all CONFIG_*_DEMUXER=yes in config.mak), i think. -- Regards, Vladimir Voroshilov mailto:voroshil@gmail.com JID: voroshil(a)jabber.ru ICQ: 95587719

dvdnav - mpdvdkit2 - libdvdcss regression
by Attila Kinali 05 Jan '07

05 Jan '07

Moin, I just run into the problem that MPlayers build in libdvdcss isnt used anymore when compiled with dvdnav support. As a lot of people like me are used to only compile MPlayer to be able to watch dvds everywhere, we'll have a lot of people who will not have libdvdcss installed seperately. Thus, would it be possible to make use of the internal libdvdcss in mpdvdkit2 to decrypt the dvd?

gcc, mplayer and profile (mcount)
by Adam Sulmicki 04 Jan '07

Hello folks, This is my last post on the subject of mcount. I have spent a quite bit of time on this to find out that the results of myserious crashes is the mcount variable. (with help from Ian Lance Taylor). I have reported the issue to both gcc and mplayer lists, and from _BOTH_ lists I got reply that they do not feel it is their problem and blamed the other package. WELL, as far as I'm concerned the issue is solved, I know how to fix it and works for me. In spirit making OSS better, I took the extra effor to report findings back to both lists. In reward I got flamed on both list. The Issue: Anyway, the scop is that once I try to compile mplayer with -pg option (or -p) then it will start myseriously crash on mplayer/libmenu/menu.c:menu_init(). It comes out that in mplayer/libmenu/menu.c there's in use "mcount" variable: # grep mcount menu.c static int mcount = 0; however, once "-pg" or "-p" options are enabled, gcc uses mcount _function_ for its internal profiling. The results are mysterious crashes on menu_init(). Suggested solutions: * Rename mcount in mplayer/libmenu/menu.c to something else. * document mcount in gcc man page * gcc prints warning. * do nothing. I can immagine that gcc developers might have intentionally left mcount() visible to user space so that user can replace gcc's mcount() with their own implementation. Just FWIW, I don't care if anything will get done about it. -- Adam Sulmicki http://www.eax.com The Supreme Headquarters of the 32 bit registers
