Some points for cd-dvd.xml
by Jiri Heryan 01 Jul '05

01 Jul '05

About a line 31 in cd-dvd.xml is sugested to use "hdparm" or "cdspeed" for slow down IDE-CDROMs and few lines after is something like there is no solution for SCSI drives. I've no experience with cdspeed but hdparm failing with IDE-CD if you use an IDE-SCSI emulation for cd writer. Best solution (after hard searching) is set a speed=<speed> option to mount command. This work better for me than hdparm even in native ATAPI with my writer, because this drive resets its speed setting with every cd exchange so it need run hdparm many times (boring and slow). Maybe it is a solution for SCSI drives too. I can't prove it myself, have no native SCSI. Next we should point reasonable speed settings because all drives do not support many speeds. For example my cd writer supports about 15 various speeds but my previous toshiba cd-rom could be set to 14x and 40x only, so if I set 24x it turn out as 40x (noisy) but after I set it <=14x , it slowed down. In my experience is 8x speed reasonable minimum and 24x reasonable maximum with noise under fans level. Any ideas? Jiri

Simple document explaining all about what/why/how tearing is... I re-read again now, it seems to me all correct and good. Anyone spot anything incorrect or misleading in it? - ods15

encoding guide draft
by D Richard Felker III 19 Jun '05

19 Jun '05

This is the draft of the old encoding guide I was working on last fall and never finished. It's far from complete and maybe slightly inaccurate in some areas, but has a lot of good information. I'm posting it here in case anyone wants to finish it or incorporate parts of it into other docs in the meantime. Rich P.S. Especially note that I retract some of the things I've said in the past about -mc 0 and -noskip... So let's discuss them before including them in official docs.

[PATCH] small wording (and syntax) fix in video.xml
by Dominik 'Rathann' Mierzejewski 17 Jun '05

17 Jun '05

Here's an attempt to re-word an unclear sentence which I stumbled upon while reviewing Polish translation. Attached Also there's a paragraph around line 2090 of video.xml which reads: <varlistentry> <term><option>-vf expand=-1:-1:-1:-1:1</option></term> <listitem><para> Although the DXR3 driver can put some OSD onto the MPEG1/2/4 video, it has much lower quality than <application>MPlayer</application>'s traditional OSD, and has several refresh problems as well. The command line above will firstly convert the input video to MPEG4 (this is mandatory, sorry), then apply an expand filter which won't expand anything (-1: default), but apply the normal OSD onto the picture (that's what the "1" at the end does). </para></listitem> </varlistentry> Does expand really convert input to MPEG4? I don't think so. R. -- MPlayer RPMs maintainer: http://greysector.rangers.eu.org/mplayer/ "I am Grey. I stand between the candle and the star. We are Grey.

[PATCH] x264 encoding guide
by Guillaume POIRIER 03 May '05

03 May '05

Hi all, Here's the much awaited encoding guide for x264, based on snacky's guide. I've made some changes to use a more impersonal phrasing and slitted it in 2 spots: codec.xml and mencoder.xml. Please comment and review. I'll probably commit it Monday night in any case (not tomorrow, as it's labor day! ;-) ) Regards, Guillaume
