[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.

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] Seeking in multirate RealMedia files.
by Zuxy Meng 21 Feb '10

21 Feb '10

Hi, The attached implements seeking in multirate RM files, with some code clean up. Now both normal (interleaved) and multirate RM files maintain current_apacket and current_vpacket and use these counters in seeking. Tested with several normal and multirate files and seemed to work fine. -- Zuxy Beauty is truth, While truth is beauty. PGP KeyID: E8555ED6

[patch] play and seek files inside multivolume uncompressed rar files
by Emiel Neggers 28 Dec '09

28 Dec '09

Hello mplayer devs, Attached to this email is a patch which i wrote about a year ago that lets you play files in uncompressed, multi-volume rar files, as long as there is only one video file inside the rars (which is often the case). It probably (surely) isn't ready for inclusion in mplayer as-is, has no error reporting, and doesn't work on rar files with compression. However, I've been using it a lot for about a year now without any problems. Do with it what you wish :) I also attached the bash file that i use to play these rar's which shows how to use this patch. Regards, Emiel p.s. this is a 2nd email, because the previous one is being held in moderation as i was not yet subscribed. the kind people on irc told me it was better to send it again so there.

Another sample from norway
by Håkon Alstadheim 27 Aug '09

27 Aug '09

This is just to motivate anybody having a spare 5 minutes into working receiving the norwegian dvb-t broadcasts ... (should also interest people from NZ) :-) I've uploaded another sample to incoming, filename hakon.alstadheim.priv.no.nrk3.ts. Attaching the standard output and error when playing below. As you can see I have patched my mplayer to force 25 fps framerate. Seems that patch no longer works as intended, but the straight (non-patched) mplayer gives similarily discouraging results when viewing. Happy hacking everybody :-) . If you want more debugging output, just tell me what and I'll try to comply. -------------------- MPlayer dev-SVN-r26171-4.1.2 (C) 2000-2008 MPlayer Team CPU: Intel(R) Pentium(R) 4 CPU 2.00GHz (Family: 15, Model: 2, Stepping: 4) CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2 Playing hakon.alstadheim.priv.no.nrk3.ts.

Hi, I suggest to increase the cmd max size from 256 to at least 1024. With the slave command `loadfile <path>`, 256 chars is easily reached. Regards, -- Mathieu SCHROETER

[PATCH] Support for DVB subtitles
by Nicolas George 18 May '09

18 May '09

Hi. The attached patch adds support for DVB subtitles. The color is currently downgraded to a single alpha channel; there is room for enhancement here. If anyone thinks that the way I plugged it directly in vf_ass, my answer is that I totally agree and I would like some help to have my previous patch accepted. Regards, -- Nicolas George
