[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.

[PATCH] Network synchronized playback using UDP
by Jason Holt 08 Sep '10

08 Sep '10

I hacked in a simple mechanism to synchronize playback between multiple instances of mplayer over a network. The master sends a UDP datagram to announce its position in the video each time it plays a frame. The slaves check to see if they're within epsilon of the master. If they are, they just advance by a frame. If not, they seek to where the master is. This works out nicely because I can dynamically tweak frame rate, seek and pause on the master and the slaves all follow along. The patch is not compliant with your coding standards. Before I do that work, I wanted to make sure it's a patch you're interested in, and see if you have any particular guidance on things I should move or change.

[RFC][PATCH]removing gmplayer
by Anton Khirnov 12 Jun '10

12 Jun '10

Hi, i think it's time to finally remove gmplayer. It's ugly and unmaintained and apparently no devs even use it. People who ask for help in #mplayer are always just told to use SMPlayer or some other frontend. Also it seems that most its users simply don't know that there are other (much better) options than gmplayer. I'm attaching a patch that removes it, except for the 'svn rm gui/' part, because it'd make the patch too big. Comments? Anton Khirnov

[PATCH]Set default mc to 1
by Carl Eugen Hoyos 08 Jun '10

Hi! Attached patch makes all PAFF samples playable (with a small, for some samples even acceptable delay), while I do not know of any sample that does not desync immediately with latest svn. Please comment, Carl Eugen

[PATCH] Add support for ARIB STD-B24 captions
by Michael Wu 21 May '10

21 May '10

Hi, This patch adds support for captions found in ARIB STD-B24 (ISDB) transport streams. It uses libass to render the captions and has support for color and positioning. Captions can be turned on in most cases with -slang jpn , assuming that there is a Japanese caption stream. Thanks, -Michael Wu

rtp support in mplayer
by chas williams - CONTRACTOR 30 Apr '10

30 Apr '10

while trying to play from rtp/mpeg-es streams i found i needed the following patch: --- stream/rtp.c.000 2008-05-13 17:37:23.000000000 -0400 +++ stream/rtp.c 2008-05-13 18:02:02.000000000 -0400 @@ -246,6 +246,9 @@ headerSize = 12 + 4*rh->b.cc; /* in bytes */ + if (rh->b.pt == 32) /* 32 = MPV from RFC 1890 */ + headerSize += 4; /* skip MPEG video-specific header RFC 2250 */ + *lengthData = lengthPacket - headerSize; *data = (char*) buf + headerSize; to skip over the 4-byte mpeg header present in the file. however, after looking at mplayer a bit harder, i see that there are two rtp decoders/demuxers. the one supplied in libavformat (apparently derived from ffmpeg) seems like it has more smarts. which one should i be using?

[PATCH] improve dvd subtitle. cmd 7 (CHG_COLCON)
by A Tanaka 22 Mar '10

22 Mar '10

When I watched japanese 'ZODIAC' dvd, subtitle was not displayed in many scene because it uses sub-pictures cmd 7(CHG_COLCON) and spudec.c don't handle it. So this patch is for that. Changes: a) handle cmd 7. b) each cmds sequence will be queued. this make possible to handle fade in/out effect(in another dvd, done with changing alpah values). c) some improvement. avoid alloc/free repeating. I tested with some dvds without any problems.(although cmd7 was only in 'ZODIAC').

Refactored as per (most) suggestions. Still no real error checking or Doxy. Stream seeking should work a bit better now.

[libass] Ignore PlayResX/Y aspect ratio for font aspect ratio.
by Nicolas George 05 Mar '10

05 Mar '10

Hi. I recently noticed that a lot of my subtitles for anamorphic encodings of DVB recordings, which used to look fine, now look horizontally stretched. I bissected the revisions and tracked back the change to this commit: # r28814 | greg | 2009-03-05 21:05:56 +0100 (Thu, 05 Mar 2009) | 1 line # # Ignore PlayResX/Y aspect ratio for font aspect ratio. What is the reason of this change? I may be mistaken, but it seems deeply wrong to mm. For example, the width of the font is not the same with vo=xv and vo=gl, because xv renders the subtitles at the resolution of the video (anamorphic, PAR=64/45) while gl renders the subtitles at the screen resolution (PAR=1). IMHO, this should not be. Regards, -- Nicolas George

[PATCH] reduce hardware MPEG decoder codec priority
by Diego Biurrun 05 Mar '10

05 Mar '10

Hardware MPEG decoders are a vintage thing of the past. Here is a patch to use software decoding by default. The minority of people that actually do have hardware decoders can easily adapt their personal configuration. Diego
