[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.

[PATCH] SDL widescreen modes

26 Jul '02

Hi, I made a patch to libvo/vo_sdl.c, which autoselect in the start a widescreen mode, if there is some. I thing it's pretty source, so it will be commited to CVS. In verbose mode mplayer will list available modes from SDL, somethink like: Mode: 0: 1152 x 768 Mode: 1: 1024 x 768 Mode: 2: 896 x 600 Mode: 3: 800 x 600 Mode: 4: 720 x 480 Mode: 5: 640 x 480 SET Mode: 4: 720 x 480 Klokan -- (\_/) Klokan Petr Pridal (o o) ---------------------------- (.) student FI MU Brno, webmaster http://www.linux.cz/ (] [) _ mailto:klokan@seznam.cz {~~~}/ ) ICQ:3674202 (') (') http://klokan.misto.cz/ \_)-(_) Look at http://www.fi.muni.cz/~xpridal/

Audio filters first design proposal
by Anders Johansson 22 Jul '02

22 Jul '02

Hi, I have written a design proposal for the new audio filter structure, it is attached to this mail. Have a look, at it. I have so far not addressed the problem of memory buffers. I would still like to make them dynamic all the way into the buffering that is made by mplayer. I need to start looking at where I should put the calls to init, uninit, play, etc - please advise me on this. /. me, //Anders

RealPlayer codec support
by Florian Schneider 22 Jul '02

22 Jul '02

Hi. I am currently working on RealPlay codec support, i.e. using the closed source codecs to decode video and audio. The current status is: - only video for RV30 is implemented right now - the extended streaming header is (I hope) completely understood and implemented. RV30 implemented a new layer below the normal packets inside the video stream, which i call subpackets. a packet may contain multiple sub packets, and a data block (the one that will be copied to memory) may be spread over several (sub) packets. - I have written some wrapper programs for logging the communication between player and codec. - video decoding for RV30 has been implemented - unfortunately the decoded data seems to be incorrect: even though the input to the RV20toYUV420Transform() and the other functions seem to be identical, the output differs, resulting in an ugly video output. - for video decoding we only use drv[23].so.6.0, the rv[23]0.so.6.0 is just for demuxing (as far as I understand) - the audio codec is half way understood, but should be easier to finish than the video part - do we only need cook.so.6.0? - the case differentiation in the demuxer is somewhat ugly at the moment At the moment I am writing down all the documentation I have on paper, so I can send the patch tomorrow. I don't think it will be ready for CVS, but hopefully some people are interested. Since RV20 has the same interface, it should be possible to support it, too. Regards Flo

[PATCH] manpage update?
by Jonas Jermann 21 Jul '02

21 Jul '02

Hi Changes: - added mmst,cddb,user/pass to synopsis - added hints about .mp3 detection (-demuxer 17) - added rawaudio and dxr2 options (patch by albeu) - added lavdopts - tried to simplify/improve -npp, [as]lang/[as]id, ao and more descriptions - added noise filter description (-vop) - added vlelim,vcelim,vstrict,vdpart,vpsize description (lavcopts) - added and removed some GUI keyboard controls - tired to make a uniform manpage: uniform EXAMPLE:, NOTE: always 4 spaces before "sub-descriptions" <options> -> <option1:option2:...> always 2 spaces between first and second column always dot at the end of a option description .TP .B -> .TP\n.B - many small fixes/typos/changes Todo/questions: - IMHO the lavcopts are too detailed, wouldn't a hint to the tech docs be better? - vfwopts, aq (lameopts) and gray (lavcopts) - Wouldn't it be better to specify the fb device like this: -vo fbdev[:device] instead of -vo fbdev -fb <device>? - looks ugly in small window - IMHO it would be better to centralize all option declaration to cfg-*.h, now they're spread over many files, but donno. - What about moving the -dump* options to mencoder? - What about this mail (DVD subtitle ripping getting there): http://www.mplayerhq.hu/pipermail/mplayer-dev-eng/2002-June/009004.html Hints: - "vbug" is NO lavdoption, it's "bug" Regards Jonas

DVD subtitle ripping getting there
by Kim Minh Kaplan 11 Jul '02

11 Jul '02

Hello, DVD subtitle ripping should now work with this. If anyone can test it, especially if anybody can confirm or deny that it is comptible with Windows Vobsub, that would be great. New options: -vobsubout <name> Vobsub file name with no extension (like -vobsub) -vobsuboutid <lang> Language code to put in the IDX file (defaults to what's read in the IFO) -vobsuboutindex <0-31> Index number to put in the IDX file (defaults to 0) Kim Minh.

BUG report: Stuck wma->mpeg1 conversion with mencoder using cvs as of 10 minutes ago

09 Jul '02

Full system details at the end of this report I have a section of a live wma8 stream which causes mencoder to get stuck at 100% cpu usage when converting to mpeg1video I discovered this tracking down why http://www.byutv.org/byutv250.asx kept hanging when playing to dxr3 I recorded to disk and extracted a sample bad clip 2MB using mencoder -ovc copy -oac copy -endpos ...... this bad clip is available at http://www.liddicott.com/bad2.asf If you try and convert to mpeg1 (as happens when playing to dxr3) with: mencoder -ovc lavc -lavcopts vcodec=mpeg1video -o bb.avi bad2.asf Then after a while it stops outputting and "top" shows 100% cpu on mencoder It is worth noting that this wma8 stream is new-ish and has 0 length frames (mplayer was recently patched for this) and may well have other strange and new things in it.

[PATCH]patch to make vob sub outside the movie
by 陆然 08 Jul '02

08 Jul '02

actually most of the codes of the patch is from salvador's sub pos patch, i just make it works properly. first it cut the vob sub to visible part, and then display the sub at the bottom of the picture, with sdl, and if we lucky that the sub is not too big, the sub will be outside the movie. BTW, it's a little bit strange that after the sub were cutted, the bug i reported (dirty sub with sdl) disappeared, now it works well with sdl:). this patch should have no linebreaks.:-P _________________________________________________________________ 与联机的朋友进行交流，请使用 MSN Messenger: http://messenger.microsoft.com/cn

encoding to huffyuv
by Marian Jancar 01 Jul '02

01 Jul '02

I want to do higher quality capturing on slow machine eg capture to a losless format and then compress. Huffyuv seems to be good choice for the capturing so if noone adds support for it to mencoder or plans to do so I would do it. The usage of huffyuv is not fundamental though, if someone has smart ideas about highspeed losless compression I would like to implement them. Marian
