If you want to use only one of +them, you can add one of "WITHOUT_MP3=1" or "WITHOUT_MPLAYER=1" to your +Make.config. + +Currently the plugins can be build with VDR 1.1.29 or later, but you should not +use version 1.1.31 as this will cause high CPU load during network streaming. +Main development platform is now VDR 1.3.x, but the plugins should work fine +under VDR 1.2.6 too.. + +Any mentioned plugin config file should be located in the "plugins" +subdirectory of your VDR config directory. For a complete description of the +config files, see the MANUAL file. + +The MP3 plugin needs some external libraries (some optionally): + +You must have installed libmad and libid3tag from +<http://www.underbit.com/products/mad/> for decoding MP3 and ID3 support. +Recommended version is 0.15.1b. To compile and install I suggest the following +sequence from the source directory (libmad and libid3tag are installed +separately, so you must execute this once for each directory): + +> configure +> make +> make install +> ldconfig + +You must have installed zlib on your system, too (zlib is used internally by +libid3tag for compressed tags). This should be no problem, as virtually every +Linux distribution includes this library. + +For playback of WAV and other sound files you must have installed libsndfile +<http://www.mega-nerd.com/libsndfile/> on your system. Recommended version +is 1.0.11. The old 0.0.x series doesn't work due to some API changes. To +compile and install libsndfile I suggest the following sequence from the +libsndfile source directory: + +> configure +> make +> make install +> ldconfig + +If you don't want to install libsndfile, you must add "WITHOUT_LIBSNDFILE=1" to +your Make.config. + +If you want to listen to CD audio, you can use cdfs +<http://www.elis.rug.ac.be/~ronsse/cdfs/> (version 0.5c suggested). I suggest +that you create a new entry in /etc/fstab and mp3sources.conf for cdfs. The +/etc/fstab entry could look like: + /dev/hdc /mnt/cdfs cdfs ro,noauto,user 0 0 +The entry for mp3sources.conf could look like: + /mnt/cdfs;CD-Audio;1 +Or if you want only WAV files to be displayed: + /mnt/cdfs;CD-Audio;1;*.wav +If you don't like cdfs, you could use any other filesystems which allows to +access the CD audio data as WAV files. + +For playback of OGG files you must have installed libvorbis and libvorbisfile +<http://www.xiph.org/ogg/vorbis/> on your system. Most Linux distributions +include packages for this. +If you don't want to install the vorbis libraries, you must add +"WITHOUT_LIBVORBISFILE=1" to your Make.config. + +The MP3 plugin can output the sound to an OSS soundcard. To compile this +support add "WITH_OSS_OUTPUT=1" to your Make.config. The output device defaults +to "/dev/dsp" (see command line option -D too). Don't forget to enable OSS +output in the plugin setup menu. + +Before compiling the plugin, you could have a look at "mp3-config.h". This file +includes a number of defines to set options and values at compile time. You +should only change defines, if you have understand the source code parts which +deal with the define. Improper settings can make the MP3 plugin to fail or to +operate unsmoothly. So you should know what you are doing. + +To build the plugin(s) type: +"make plugins" +from the VDR source directory. + +To make the progressbar work with the MPlayer plugin and slave mode you need to +apply a small patch to mplayer. Select an appropriate patch file for your +MPlayer version from the patches subdirectory. Apply the patch and recompile +MPlayer. + +Early 0.90rc versions of MPlayer need a patch to enabled HEAD driver support +too. You will find one for 0.90rc1 in the patches subdirectory. Probably you'll +have to point configure to the new DVB include files with +--with-extraincdir=/usr/local/src/DVB/include or where ever you have stored the +files. MPlayer versions later as 0.90rc5 allow to select HEAD support with a +configure option or even detect this automatically. + +Command line options: +--------------------- + +Both plugins have a command line option -m/--mount to define the name and +location of the mount script. The default mount script is "mount.sh". This +script is called from the plugin with 2 options on the command line. The first +is one of mount/unmount/eject/status and gives the action to perform. The +second one is the base directory as defined in "mp3sources.conf" or +"mplayersources.conf". The script must return the exit code 0 if the action was +successful and 1 if the action failed (see the comments in the example +"mount.sh" script which comes with the archive). + +The MP3 plugin maintains a cache for information scanned from song files (e.g. +ID3 tags). This information is saved to the id3info.cache file by default +located in the video directory. You can use command line option -C/--cache to +specify a different directory for this file. + +If you are using cdfs, the MP3 plugin is able to query a CDDB database for the +song information (like title, artist). Local CDDB lookups can be enable from +the setup menu and you must give the path to your local CDDB files with +commandline option -B/--cddb. The database layout follows the xmcd standard +(one subdirectory level for the categories, individual files for every disc). +The settings for remote CDDB lookups can be found in the setup menu, too. Any +information retrieved from a remote host is stored to your local CDDB database, +so the user running VDR needs write access to this directory. + +If you are using any of the networking capabilities and you have a dial-up +network, you can use the commandline option -n/--network to give a script name. +This script is called before and after any network access and receives one +option on commandline. This can either be "up" or "down", depending on if it's +before or after the network access. In the "up" case the script should not +return before the network is connected and useable. By default the plugin +assumes that network access can be done at any time without prior action. + +If you want to use the OSS output capability but your soundcard device is not +"/dev/dsp" (which is the default) you can use the commandline option -D/--dsp +to give an alternative soundcard device. + +If you want to use the cover image display, you have to provide an image +converting script. Usually your covers are in a common image format like e.g. +JPEG or PNG, but the MP3 plugin can only display MPEG (still) frames. The +conversion is done by the script, which takes two arguments: first the filename +of the image file and second the filename or the resulting MPEG file. The +script also has to take care that any needed subdirectories in the cache are +created e.g. mkdir -p. You will find an example script in the examples +subdirectory. By default the script is called "image_convert.sh", but you can +use the commandline option -i/--iconv to change the name and location of the +script. +To speed up consecutive accesses to the same image, the converted frames are +cached on disk. The default cache directory is "/var/cache/images/mp3". You can +change this location with the commandline option -c/--icache. +Don't forget to enable the image display in the plugin setup menu. +The search order for images is: +- An image in the same directory as the song, named like the song but with the + song extension replaced with the image format extension + e.g. test.mp3 -> test.jpg +- An image named "cover" with the image format extension in the same directory + as the song (album cover). + e.g. cover.gif +- An image named "artist" with the image format extension in the parent + directory of the song (artist image). + e.g. artist.png +- An image named "background" with the image format extension in the base + directory of the MP3 source. +For all locations the extensions "jpg", "png" & "gif" are checked (in that +order). If no image can be found, a full screen black image is displayed (this +is included statically in the plugin). + +MPlayer is called through a script called "mplayer.sh" with the filename to +play as first argument and the phrase SLAVE as second argument if slave mode is +enabled. You can use the commandline option -M/--mplayer to change the name and +location of the mplayer script. The script has to call MPlayer with all the +necessary options. + +The script should parse the SLAVE keyword too and give appropriate options to +MPlayer. To enable slave mode you must give at least the "-slave" option, while +I suggest "-slave -nolirc -quiet". + +You can use the mplayer.sh.example file, which comes with the archive, as a +starting point. Juri Haberland maintains a full featured mplayer.sh file which +is available at <http://batleth.sapienti-sat.org/projects/VDR/>. + +Summary of commandline options: +------------------------------- + +MP3 Plugin: +-m CMD, --mount=CMD use CMD to mount/unmount/eject mp3 sources +-n CMD, --network=CMD execute CMD before & after network access +-B DIR, --cddb=DIR search CDDB files in DIR +-C DIR, --cache=DIR store ID3 cache file in DIR +-D DIR, --dsp=DIR device for OSS output +-i CMD, --iconv=CMD use CMD to convert background images +-c DIR, --icache=DIR cache converted images in DIR + +MPlayer plugin: +-m CMD, --mount=CMD use CMD to mount/unmount/eject mplayer sources +-M CMD, --mplayer=CMD use CMD when calling MPlayer |
