UPDATE: mplayer.git (now known as mplayer2) is available from Christian Marillat's repository and Debian experimental. I suggest you get it from one of these sources instead... If you are reading this, it is probably because you are looking for a Debian package of mplayer which has Matroska ordered chapter support and you do not want to wait for the approximately $(dd if=/dev/urandom bs=128 count=1 2>/dev/null | tr -cd 0-9) seconds it will take to get an official one. If you are not a Debian (or Ubuntu or other derivative) user or you are not looking for a debianization of the mplayer.git development tree, then you are probably in the wrong place. These files are based on Christian Marillat's mplayer packages, which you can find here: http://www.debian-multimedia.org/ All I have done is made them build a snapshot of mplayer.git, which you can find here: http://repo.or.cz/w/mplayer.git For the ordered chapters support to work, I think you need a fairly recent version of the ffmpeg libraries. 5:0.6~svn20100603-0.0, from Christian's repository, is working great for me (and to try an older one you will probably have to rebuild the mplayer packages). If you use these packages, please bear in mind the following things: 1) I make no warranty whatsoever. These packages are built from an experimental/development tree, for one thing! Also, Christian's control file does not seem to depend on every package it might build a feature from, so these packages may not support all the optional features his do. I made some effort to get most of them. You can always rebuild the package yourself... 2) If you have problems with this package, there is an approximately zero percent chance I want to hear about them. I suggest you revert to the official mplayer packages and try to reproduce your problem with them. If it reproduces there, you can file a bug report against those packages and maybe I will pick up whatever fix they make. If it does not reproduce there, well that's a bummer.
