[PATCH] New filter vf_ivtc, smart dropping of every 5th frame
by Johannes Guenther 12 Dec '03

12 Dec '03

Hi, after using mencoder for awhile I came across movies with (real) 29.97 fps which were created from a 24 fps source by inserting a duplicate frame after every 4th frame. When (re)encoding these movies it would be clever to drop these duplicated frames to save bandwidth and to eliminate the jerky motion artefacts. But to only use the option '-ofps 23.976' is not satisfactory because mencoder bluntly drops every 5th frame regardless of being duplicates or not; or missed I something? So I wrote a filter which does the job - other programs like transcode or VirtualDup already have one. There have also been requests concerning this issue: http://mplayerhq.hu/pipermail/mplayer-users/2002-September/020628.html http://mplayerhq.hu/pipermail/mplayer-dev-eng/2002-January/004502.html Some implementation details; how I see this problem; things I would like to discuss: - To detect the duplicated frames it is necessary to buffer at least 6 frames (you cannot display/encode the frames and decide afterwards 'Oh, I wanted to skip that frame'). But buffering (at least of this amount) is not supported by the vf-API (am I right?). So I had to expand it by introducing a new image-type MP_IMGTYPE_BUF. - Unfortunately I have to memcpy the whole frame to the buffer. It would be better to store only the meta-data/image-structure but this did not work (the information was lost during two calls of 'put_image'). - You need to also specify the '-mc 0' and '-noskip' option to mencoder otherwise mencoder complains about missing the first frames (which are gone to the buffer and were not yet displayed) and tries to insert frames. - 'put_image' is not noticed whether this is the last time it is called, but it needs to flush the buffer then, otherwise the last frames are lost. This cannot be done in 'uninit' because then everything is already over (files closed, image-structures invalid). The hack is to provide the total frame number as a hint to vf_ivtc via commandline, thus 'put_image' knows when it is its last time. - All in all it seems that the libMPcodecs API does not like buffering and skipping frames that much, it is not designed to provide such things, is it? For example a return code of 0 or -1 to indicate that a frames was skipped. (At least this information is not passed to mencoder) - Is a filter really the right way? Maybe it is better to provide this functionality directly by mencoder/mplayer. I'm not so intimate with the API details so it is likely that there are more elegant solutions. Despite all the problems and hacks the filter works here quite well and produces the correct result even if there is a change in the pattern of duplicated frames (counted as 'resyncs'). So, what so you think? Bye, Johannes -- http://beam.to/Hawk PGP Key fingerprint = 2F 72 52 1C CF 86 96 35 8A DD 8E F5 C6 05 CE C5

As I told you all earlier, I've made a script to create .po files from the help files. By doing this I discovered some flaws in the translation files. This is the diff. I'm also attaching the new version of my tiny script.

[PATCH] README

17 Oct '03

Hello everybody! Hoping to bring the linewrap saga to a good end, here is my latest patch for the README. Lines are wrapped on column 80, meaning there are at most 79 characters of text on one line. The changes: - Added Step0: Getting MPlayer Download instructions are consolidated in one place instead of repeated at 3 different places throughout the text. Plus I included instructions for accessing CVS. - I mention the ~/.mplayer/Skin/ and ~/.mplayer/font/ installation locations for normal users. - A bunch of wording updates.

I would like to suggest adding the following patch to the cvs [requires the patch posted a few days ago, which adds the module parameter "major"]: This patch adds the module parameter "mga_number". On a system with multiple matrox cards or a matrox card with multiple chips, this parameters selects which matrox card/chip is used (in the order of found devices). Then, one can load the mga_vid module once for each card. Say, on a system with two cards, the /etc/modules.conf can look like: --- alias char-major-178 mga_vid alias char-major-179 mga_vid options char-major-179 -o mga_vid-1 major=179 mga_number=1 --- Note that the "-o" option loads a module under a different name. This allows loading the mga_vid module several times. With a mknod /dev/mga_vid0 c 178 0 mknod /dev/mga_vid1 c 179 0 one can then run mplayer on both cards at the same time: mplayer -slave -vo mga:/dev/mga_vid0 movie1.avi & mplayer -vo mga:/dev/mga_vid1 movie2.avi Please comment [arpi, attila, eyck, ...] (and commit?) this patch.

Smooth Fast-Forward/Slow-Motion
by Raindel Shachar 15 Jul '03

15 Jul '03

Hi. I have seen your discussion about Fast-Forward (http://mplayerhq.hu/pipermail/mplayer-dev-eng/2003-February/015835.html) I am working on it too, from a different direction: I have started to patch libaf, so that it will handle the play-speed changes using the SoundTouch library (http://www.sunpoint.net/~oparviai/soundtouch/) which will allow speeding up the video, keeping the audio in sync and preventing the pitch change (better than what you get when playing VHS in double speed, isn't it?). I haven't finish it yet, but not much has left. I am not near the box which I use for developing it, so I can't attach my patch so far :-(. It seems like combining my patch with Struan Bartlett's one will give the perfect result. BTW: the magic numbers (the speed up/down factor, max/min speed) in Struan Bartlett's patch should become a config option (IMHO). BTW2: do we really want to reset the speed each time the user change between speeding up and speeding down? I would like it to behave like a knob, not like some very weird switch with a knob next to it. BTW3: since you reminded EDL: does anybody work on it correctly? Do you have any road-plan about how to expend it?

Offer of help to get me started
by Evil Kosh 03 Jun '03

03 Jun '03

Hi, I'd like to start a bit of coding on mplayer and I thought the best way to get acquainted with the code and how it works is to look through it and see what I could fix. I immediately saw that there were a number of different styles that people were developing with. Some people would use braces with for and if statements, others would not, some people would put the break in a case statement before the closing brace, others would not. I thought perhaps it would be a good idea to get acquainted with the code and help out at the same time. Also I found some parts of the code with tabbed indentations and others with space indentations. Would anyone here object to a clear style guide being formed from the developers here? I'd be happy to reformat the code along those guidelines, if it means I can help out, everyone gets clear, well formatted code along an agreed style. What do you think? well, I'm 1/2 way through reformatting mplayer.c with what I think is a good style. It's consistant anyhow. So if people dont like it then I can always alter it. I'll post it to the list when I've finished and let people judge for themselves whether they think this reformatting exercise is a good idea or not. thanks for listening and I hope a favourable response. -- Evil Kosh <evil_kosh_uk(a)yahoo.co.uk>

[PATCH] DTS support for -ac hwac3
by Peter Schüller 28 Apr '03

28 Apr '03

Hi, I've appended a replacement for the file "libmpcodecs/ad_hwac3.c", which adds DTS passthrough support (due to the many changes, a diff file would have been larger). I must admit, that I have NO knowledge of the DTS encoding and the code is entirely based on the DTS code from "ogle" (http://www.dtek.chalmers.se/~dvd/) It is also not very widely tested, as I don't have many DTS dvds. Note that the DTS streams have IDs starting at 136; so if you have a dvd with the first audio stream being AC3 and the second DTS, you have to use "-aid 128" and "-aid 137", resp. -- Peter Schüller peterschueller(a)telemed.de

MPlayer G2
by Arpi 15 Apr '03

15 Apr '03

Hi, As I promised when I announced my leaving of the project maintainership, I started some new video player project (nearly) from scratch. For now I call it MPlayer G2 (as generation 2). Don't think of char-by-char rewrite, I'm trying to reuse as many as possible from the current mplayer, but I want to cleanup code and do some radical changes so this is much easier than hacking the CVS. My time plan: 1. Building the stream layer library, based on mplayer's libmpdemux. I'm over it partially, see here: mplayerhq.hu/~arpi/mplayer-G2-preview1.tar.gz I need to port the rest of the drivers (like smb://, mms/mst/pnm streaming, cdda/cddb) but it's usable for reading file, fifo, vcd, dvd, and http. Adding new protocols is very easy, opposed to the old code. 2. Building the demuxer layer. It's a bit harder, as I want to add multiple (more than one video/audio) stream demuxing support, and also modularize the code. I'll also add runtime index buliding for backward seeking and support for forward seek without index. I'll also make subtitle streams able to handle ascii subs, vobsubs, closed captions etc. 3. Move libmpcodecs (and libavcodec, libmpeg2, liba52, libaf) 4. Make some minimal libao/libvo using the new API (tech/libvo.txt). I don't want to port/move all vo (ao) drivers, just a few what I can test and understand. Others may be ported later by other developers. 5. Implement libmplayer, a core engine for video playback. I don't plan (and don't want) to include any UI (including commandline one) in this project. No libinput, no playtree, no configfile parsing, no OSD control (but osd object renderer and subtitle parsers will be there). I want to separate the player core completely from the UI. And I also want to separate the sub-modules (like stream, demuxer, codecs) from each other as possible, to be usable for other programs, and to be testable without the rest. Why? Good question. I won't (and really can't) answer. Don't worry, it is not a fork, it is not an alternative of mplayer (yet). It's a (very)long-term thing i plan to do since a long time ago. It may be the base of mplayer v2.0 once (but you'll make 1.0 for sure before this is getting usable) Another possibility is integrating cleanup'ed parts into the mplayer 'main' tree, so they will be usable (and will be tested) before mpG2 is ready for use. If anyone interested in developing this "project", tell me, i'll put the stuff into CVS then. A'rpi / Astral & ESP-team -- Developer of MPlayer, the Movie Player for Linux - http://www.MPlayerHQ.hu
