[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.

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] 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

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 :-) .

[patch] Support EAC3 in MKV container
by Andrew de Quincey 17 Mar '09

17 Mar '09

Hi, I've just tried muxing an EAC3 track into an MKV using mvktoolsnix 2.4.1. It muxed it ok, but mplayer rejects it with an unknown codec "A_EAC3". The support for this codec was added to mkvtoolsnix on 2007-03-02 (see http://www.bunkus.org/videotools/mkvtoolnix/doc/ChangeLog) The attached patch adds support for new "EAC3" stream type in the mkv container. Note: I originally tried simply setting it to the mplayer standard AC3 a_formattag 0x2000, but this does not work, so I have used the EAC3 fourcc instead. Unfortunately the channel ordering is /definitely/ screwed (all dialogue is coming from the rear left + front right speakers); I'll investigate this issue later by comparing with a player under windows.

[PATCH] Fix unpause with key_down_event command
by Adrian Stutz 07 Mar '09

07 Mar '09

Currently, it's not possible to unpause MPlayer with the key_down_event command (with a key code mapped to the pause command, of course). Steps to reproduce: mplayer -quiet -slave movie.avi key_down_event 32 # MPlayer pauses key_down_event 32 # MPlayer plays a frame and then pauses again pause # MPlayer unpauses correctly Here's what happens: * The key_down_event command will exit the pause loop without being processed * The main loop processed the key_down_event and resolves it to the pause command * The pause command gets processed and re-pauses playback The attached patch takes advantage of the new run_command in the pause_loop and lets it process the key_down_event command. The only thing the key_down_command does is re-injecting the key into the input anyway, so there should be no problems as far as I can tell. This way, the key_down_event gets processed as a regular key event, exits the pause loop with CMD_PAUSE and is handled correctly. As added benefit, key_down_event will no longer exit the pause loop if there's no binding for the key code. (Interestingly, MPlayer OSX is using key_down_event and many users use the space bar to pause/unpause movies. That only works because the short time MPlayer returns to playback triggers other commands that then exit the pause loop.) Greetings Adrian

[PATCH] vo_macosx: fix device_id option after r28165
by Adrian Stutz 26 Feb '09

26 Feb '09

I missed the screen_force BOOL in my patch to vo_macosx to replace the custom options parsing with subopt_parse(). Because screen_force is never set to YES anymore, the device_id option has no effect on fullscreen. The attched patch fixes that and removes screen_force, since screen_id is only used to force fullscreen anyway. The patch instead allows screen_id to be negative for automatic fullscreen device selection and assumes a forced selection for any positive value. Patch also includes update of the manpage that includes the new negative value of device_id. Greetings Adrian
