GUI Icon
by Ingo Brückl 10 Jan '12

10 Jan '12

Although I like the MPlayer logo, I think that it isn't really suitable for a desktop icon. On Bugzilla (http://bugzilla.mplayerhq.hu/show_bug.cgi?id=710) there is an offer for a GUI icon set that is quite nice. There is licence information for the Tango Desktop Project Icon Library, but it is missing for the Tango Fridays which supposably is a problem. If there is no general objection in using these icons for the GUI, I could try to contact the creator, Andreas Nilsson, and ask for a full set of these icons and a licence information to include both to the MPlayer repository. Would that be OK? Ingo PS: Where can I find the original (svg?) of the MPlayer logo?

[PATCH] add support of compression algorithm 3 in mkv demuxer
by Alexander Beregalov 02 Jan '12

02 Jan '12

Specs from http://www.matroska.org/technical/specs/ : ContentCompAlgo The compression algorithm used. Algorithms that have been specified so far are: 0 - zlib, 1 - bzlib, 2 - lzo1x, 3 - Header Stripping. ContentCompSettings Settings that might be needed by the decompressor. For Header Stripping (ContentCompAlgo=3), the bytes that were removed from the beggining of each frames of the track. I have such file, it works for me. | + A track | + Track number: 2 | + Track UID: 2 | + Track type: audio | + Lacing flag: 1 | + Default flag: 1 | + Codec ID: A_AC3 | + Content encodings | + Content encoding | + Content compression | + Algorithm: 3 (header removal) | + Settings: length 2, data: 0x0b 0x77 See an attachment. Please comment.

Playlist recognition
by Ingo Brückl 29 Sep '11

29 Sep '11

Is there a special reason for commenting // { "pls", DEMUXER_TYPE_PLAYLIST }, // { "m3u", DEMUXER_TYPE_PLAYLIST }, in libmpdemux\extension.c? I always felt annoyed by having to use option '-playlist' for playlists which is especially irritating if you'd like to pass both playlists and files to play as arguments. These should really be uncommented for convenience of the user. Ingo

[PATCH] Fix for mpeg2 A/V sync bug.
by Steaphan Greene 18 Aug '11

18 Aug '11

The attached patch fixes the bug with vob files (and, presumably other mpeg2 content) caused by the A/V sync code added with r32055/32056. I believe this solution should cause no other harm. Basically, it now just removes the last_pts data when one of these pts changes occurs in the mpeg2 stream. That way, the A/V resync code in question ignores this frame, and no longer breaks anything. It seems likely that this same sort change may be needed for other cases where the pts is non-uniform, to prevent this resync from causing this same problem. However, I leave that to someone who understands all these cases better than I. For my part, I am fairly confident that this fixes the bug I found, without damaging anything else. -- Steaphan Greene <sgreene(a)cs.binghamton.edu> Lecturer, Computer Science, Binghamton University GPG public key: http://www.cs.binghamton.edu/~sgreene/gpg.key.txt

[PATCH] build: drop BeOS support
by Diego Biurrun 15 Aug '11

15 Aug '11

BeOS is dead and support has been dropped from FFmpeg/Libav a long time ago. The support code that was added years ago adds considerable clutter while not providing any benefit, so it's better to drop it outright. Support for Haiku, the FOSS replacement of BeOS remains unaffected. --- Makefile | 1 - configure | 49 +++++-------------------------------------------- cpuinfo.c | 4 ---- mpbswap.h | 4 ---- osdep/shmem.c | 2 -- osdep/swab.c | 33 --------------------------------- osdep/timer-linux.c | 3 --- 7 files changed, 5 insertions(+), 91 deletions(-) delete mode 100644 osdep/swab.c diff --git a/Makefile b/Makefile index 581d001..3bc6595 100644 --- a/Makefile +++ b/Makefile @@ -182,7 +182,6 @@ SRCS_COMMON-$(NEED_MMAP) += osdep/mmap-os2.c SRCS_COMMON-$(NEED_SETENV) += osdep/setenv.c SRCS_COMMON-$(NEED_SHMEM) += osdep/shmem.c SRCS_COMMON-$(NEED_STRSEP) += osdep/strsep.c -SRCS_COMMON-$(NEED_SWAB) += osdep/swab.c SRCS_COMMON-$(NEED_VSSCANF) += osdep/vsscanf.c SRCS_COMMON-$(NETWORKING) += stream/stream_netstream.c \ stream/asf_mmst_streaming.c \ diff --git a/configure b/configure index a332996..cdaa83a 100755 --- a/configure +++ b/configure @@ -208,7 +208,6 @@ issystem() { } aix() { issystem "AIX"; } amigaos() { issystem "AmigaOS"; } -beos() { issystem "BEOS"; } bsdos() { issystem "BSD/OS"; } cygwin() { issystem "CYGWIN"; } darwin() { issystem "Darwin"; } @@ -1436,10 +1435,7 @@ if test -z "$_target" ; then # OS name system_name=$(uname -s 2>&1) case "$system_name" in - Linux|FreeBSD|NetBSD|OpenBSD|DragonFly|BSD/OS|Darwin|SunOS|QNX|GNU|BeOS|MorphOS|AIX|AmigaOS) - ;; - Haiku) - system_name=BeOS + Linux|FreeBSD|NetBSD|OpenBSD|DragonFly|BSD/OS|Darwin|SunOS|QNX|GNU|MorphOS|AIX|AmigaOS|Haiku) ;; IRIX*) system_name=IRIX @@ -1467,7 +1463,7 @@ if test -z "$_target" ; then # host's CPU/instruction set case "$(uname -m 2>&1)" in - x86_64|amd64|i[3-9]86*|x86|x86pc|k5|k6|k6_2|k6_3|k6-2|k6-3|pentium*|athlon*|i586_i686|i586-i686|BePC) host_arch=i386 ;; + x86_64|amd64|i[3-9]86*|x86|x86pc|k5|k6|k6_2|k6_3|k6-2|k6-3|pentium*|athlon*|i586_i686|i586-i686) host_arch=i386 ;; ia64) host_arch=ia64 ;; macppc|ppc|Power*) host_arch=ppc ;; ppc64) host_arch=ppc64 ;; @@ -2936,23 +2932,6 @@ fi ###################### -echocheck "-lposix" -if cflag_check -lposix ; then - extra_ldflags="$extra_ldflags -lposix" - echores "yes" -else - echores "no" -fi - -echocheck "-lm" -if cflag_check -lm ; then - extra_ldflags="$extra_ldflags -lm" - echores "yes" -else - echores "no" -fi - - echocheck "langinfo" if test "$_langinfo" = auto ; then _langinfo=no @@ -3106,14 +3085,13 @@ echores "$_nanosleep" echocheck "socklib" # for Solaris (socket stuff is in -lsocket, gethostbyname and friends in -lnsl): -# for BeOS (socket stuff is in -lsocket, gethostbyname and friends in -lbind): cat > $TMPC << EOF #include <netdb.h> #include <sys/socket.h> int main(void) { gethostbyname(0); socket(AF_INET, SOCK_STREAM, 0); return 0; } EOF _socklib=no -for _ld_tmp in "" "-lsocket -lbind" "-lsocket -ldnet" "-lsocket -lnsl" "-lnsl" "-lsocket" ; do +for _ld_tmp in "" "-lsocket -ldnet" "-lsocket -lnsl" "-lnsl" "-lsocket" ; do cc_check $_ld_tmp && _ld_sock="$_ld_tmp" && _socklib=yes && break done test $_socklib = yes && test $_winsock2_h = auto && _winsock2_h=no @@ -3813,19 +3791,6 @@ fi echores "$_vsscanf" -echocheck "swab()" -_swab=no -define_statement_check "_XOPEN_SOURCE 600" "unistd.h" 'int a, b; swab(&a, &b, 0)' || - statement_check "string.h" 'int a, b; swab(&a, &b, 0)' && _swab=yes -if test "$_swab" = yes ; then - def_swab='#define HAVE_SWAB 1' - need_swab=no -else - def_swab='#undef HAVE_SWAB' - need_swab=yes -fi -echores "$_swab" - echocheck "POSIX select()" cat > $TMPC << EOF #include <stdio.h> @@ -5014,7 +4979,7 @@ EOF if cc_check $_inc_tmp $_ld_tmp >>"$TMPLOG" 2>&1 ; then _sdl=yes elif cc_check $_inc_tmp $_ld_tmp -lstdc++ >>"$TMPLOG" 2>&1 ; then - # HACK for BeOS/Haiku SDL + # HACK for Haiku SDL _ld_tmp="$_ld_tmp -lstdc++" _sdl=yes fi @@ -5816,8 +5781,6 @@ if test "$_libdvdcss_internal" = yes ; then extra_ldflags="$extra_ldflags -framework IOKit -framework Carbon" elif cygwin ; then cflags_libdvdcss="-DSYS_CYGWIN -DWIN32" - elif beos ; then - cflags_libdvdcss="-DSYS_BEOS" elif os2 ; then cflags_libdvdcss="-DSYS_OS2" fi @@ -7390,7 +7353,7 @@ echores "$_pvr" echocheck "ftp" -if test "$_ftp" = "auto" && test "$networking" = "yes" && !

[PATCH] Allow EDLs to work on audio files (fwd)
by Stéphane Doyon 04 Aug '11

04 Aug '11

Saw no response to this, resending. ---------- Forwarded message ---------- Date: Sat, 28 May 2011 19:30:27 -0400 (EDT) From: Stéphane Doyon <steph(a)odo.sdoyon.internal> To: MPlayer-dev-eng(a)mplayerhq.hu Subject: [PATCH] Allow EDLs to work on audio files I had need to use an EDL on an audio file and was surprised to get this error: "Cannot use EDL without video, disabling." It wasn't obvious to me why there should be such a constraint. I took an admittedly quick look at the code, and found only the position was obtained from the video stream, and there seems no reason it can't use the audio position just as well. I made the simple change to use the audio position when there's no video, and it appears to work. Thanks -- Stéphane Doyon <s.doyon(a)videotron.ca> http://pages.videotron.com/sdoyon/

solution of av desync on capturing with mencoder
by Jarek Czekalski 23 Jul '11

23 Jul '11

After years of using mencoder to capture and encode videos I found a way to achieve a/v synchronization which is better than the current mencoder solution. Instead of adjusting video I suggest adjusting audio. I have 2 patches to mencoder, which I'll post if I get a positive receive. PROBLEM DESCRIPTION Capturing from v4l2 and alsa. The sound card has a different timer than the video frames timer which results in a skew between audio and video. Mencoder currently drops or duplicates frames when it detects the time difference. This solution synchronizes audio with video but has the following drawbacks: 1. Duplicated or dropped frames produce jerky videos, especially on interlaced source. 2. Sound card can produce strange fluctuation which forces mencoder to duplicate and insert frames in a short period which spoils the video quality even more. If a 1 hour video should have 10 duplicated frames, instead it has 60 duplicated and 50 inserted frames. ALTERNATIVE SOLUTION Adjusting sound to video seems more reasonable to me. So we need to capture with -noskip and scale the audio to match the video duration. What do we need? 1. Calculation of the audiorate 2. Correction of the initial skew between audio and video. If I turn on -noskip, then I have initial skew between audio and video of about 0.1s. With skipping allowed mencoder would fix this. The user makes the audio adjustment in his script using sox or the native scaletempo filter. Patch for 1. Report audiorate in status line. I suggest introducing -reportaudiorate switch. The status line could then look like this: Pos:3569.4s 89234f ( 0%) 25.00fps Trem: 0min 0mb tc:-0.513 (r:1.000144) r is the audiorate that should be passed to an audio scaler. After finished encoding a following line is also printed: duplicated: 2, bad: 0, skipped: 0, v_timer_corr: -0.523, audio_scale: 1.0001453 The audio_scale here is the final audio rate. Patch for 2. The switch -noskipafter would allow mencoder to skip frames during the first 2 seconds of encoding. After 2 seconds it behaves as if -noskip was specified. ADVANTAGES OF A NEW SOLUTION Clean video without any corrections. No noticeable sound quality loss, at least using sox. No noticeable a/v desync on my sound card. Is there a chance for commiting these 2?

[PATCH] configure: set HAVE_LOCAL_ALIGNED_* for x86_64
by Nicolas George 20 Jul '11

20 Jul '11

Hi. The attached patch does as the subject and the rest of the commit message say. It may be worth investigating why the fallback for LOCAL_ALIGNED_16 does not work, though. (And the router in front of my mail server has gone mad; I have taken temporary measures, I hope they will work; sorry if anything goes wrong.) Regards, -- Nicolas George

How to catch the events in the MPLAYER?
by hengxing 18 Jul '11

18 Jul '11

Hi, I'm a freshman in mplayer development. And I'm not familiar with the source code of the MPLAYER. Now, I hope the mplayer can catch some events, and then put these events to a pipe fifo on linux. The following are the events list: AUDDEC_EVT_NOT_KEEPING_UP : Audio decoder is unable to continue decoding at the current rate. AUDDEC_EVT_KEEPING_UP : Audio decoder has resumed being able to continue decoding at the current rate. AUDDEC_EVT_BUFFER_FULL : Audio decoder buffer is full AUDDEC_EVT_BUFFER_EMPTY : Audio decoder buffer is empty AUDDEC_EVT_BITRATE_CHANGE : Audio bitrate has changed AUDDEC_EVT_FREQUENCY_CHANGE: The audio sampling freq has changed AUDDEC_EVT_DATA_ERROR : Audio decoder error has occurred AUDDEC_EVT_PTS_EXPIRE : Audio pts expiration event. VIDDEC_EVT_NOT_KEEPING_UP : Video decoder is unable to maintain the selected decode rate VIDDEC_EVT_KEEPING_UP : Video decoder is again able to maintain the selected decode rate VIDDEC_EVT_BUFFER_FULL : Video decoder input buffer is full VIDDEC_EVT_BUFFER_EMPTY : Video decoder input buffer is empty VIDDEC_EVT_UNSUPPORTED_STREAM_TYPE : stream type is unsupported VIDDEC_EVT_IFRAME_DECODED : an IFRAME has been decoded VIDDEC_EVT_STREAM_INFO_CHANGE: Change in the stream characteristics VIDDEC_EVT_DATA_ERROR : stream data error How can I do this work? Thanks everyone for your reading Best Regards xhx321
