MythVideo allows for cataloging and playback of a variety of video file formats. It can perform automatic meta data look ups on themoviedb.org or IMDB as well as retrieve poster artwork. You can also add your own Meta data to your own videos and add custom poster artwork to videos.
It features three different "views" on your collection:
- Browse view - Shows a single video on screen at once with its metadata.
- Tree view - Presents your videos in a view similar to the watch recordings screen. This view can be configured to show file/subdirectories.
- Gallery - Presents you with numerous titles at once laid out in a view similiar to MythGallery.
MythVideo can use MythTV's internal media player, to play back the video files, by specifying "Internal" as the player. Optionally, it can be configured to use external players such as Xine or mplayer.

MythVideo is a plugin module for MythTV. It is installed by default with Myth focused distributions like MythBuntu. If you install MythTV manually, the plugin modules are not automatically installed. You can see that MythVideo is not installed because the 'Watch Videos' menu item is missing from the Media Library sub menu. Also 'Optical Disks' is missing from the main menu and 'Video Manager' is missing from Utilities / Setup menu.
Instructions For Specific Distributions
Debian derived (Ubuntu etc)
From a command shell or konsole window, type or paste this command
sudo apt-get install mythvideo
Then restart MythTV. It should load available modules.
- Add the packman repository if you haven't already (this should have been done to install MythTV though).
zypper addrepo http://packman.mirrors.skynet.be/pub/packman/suse/11.1 Packman
- Install it:
zypper install mythvideo
- Create the movie poster directory
mkdir /var/lib/mythdvd;mkdir /var/lib/mythdvd/temp
Now read MTD, which you'll also need.
In the MythVideo setup (Settings-> Videos Settings-> General Settings), you can enter your video directories as a colon separated list.
All video files must be readable as part of the local filesystem. This means if you have a separate frontends and backends, you must share the directories remotely as described in Mediashares (perhaps with NFS).
You can place a file named folder.(png | gif | jpg) into a folder that is accessible to MythVideo and it will be used when the gallery view is displayed instead of a plain folder icon.
The MythTV Internal player is the recommended player for Video and DVD playback from 0.21 onwards. It will also play DVDs and DVD isos will full menu and subtitle support. It uses the same OSD, settings, remote bindings and audio configuration as playback of recordings making it much easier to setup and use than an external player. It supports almost all video formats and content including High Definition and in addition a wide range of easily accessible features including configurable aspect ratios, picture fill modes, timestretch, bookmarks, video editing, automatic locale based or manual selection of subtitle and audio streams and much, much more.
To use the Internal player in "File Extensions" set:
- Type in file suffix (eg mpeg or avi...)
- File Type to: "Internal" or blank
- Default player is unticked
Rebuild seek table
Some mp4s don't seek correctly, so you might have to build a seek table using a command like so:
mythcommflag --video myvideo.mp4
The symptoms are the internal player not displaying the correct time in the OSD, seeking being "weird" such as going 1-2 minutes forward in time when you hit 'rewind'.
If your movies stutter and speed up near the end (around the last 20 minutes or so), an easy fix is to run mencoder on the movie file to fix it. A few minutes of computing time and your movies will be good as new. Visit this link for more information, as well as a script to run after ripping movies to make sure they're good before you watch them.
There are multiple ways to import DVD's to your MythTV system.
Importing with Frontend
To import a DVD using you frontend system, click on "Import DVD" from your "Optical Disks" item on the MythFrontend Front Page. For more information see the MythDVD page.
Importing with Networked Computer
MythDVD can rip DVDs into your MythVideo folders but it does tie up a frontend. You may wish to rip DVDs on other machines on your network e.g. your fileserver. I've found the following procedure works well:
- Run lsdvd to find the largest DVD title, it's usually 1.
- Run vlc, pick File/Open Disc and select that title.
- Check VLC plays the programme you want and gets to the end credits (skip forward).
- Stop playback and pick File/Open Disc again, select the track and click Stream/Save and then Settings... (screen shot)
- In the Stream output dialog click File in the Outputs box and fill in the Filename, select MPEG PS and Select all elementary streams.
- Click OK and VLC will rip the track into the chosen file.
- Test the rip with something else like mplayer.
At this point MythVideo can see the file but you might want to go into the VideoManager on a frontend so you can fix the metadata, grab a poster etc.
If you're using an external player you're finished but if you're using the Internal player you won't be able to skip forward or backward until you add a seektable for the file. To do this I run
mythtranscode --mpeg2 --video --buildindex --infile "<Movie>.mpg"
It may leave a zero length file called <Movie>.tmp which you can remove.
The mythcommflag man page indicates it can also do this but it fails dismally for me, maybe because DVD MPEG streams can (and do) change characteristics midstream. Other DVD ripping methods are available but VLC has given me the best results. Simply copying the DVD files or using vobcopy doesn't work well.
Wrong audio track on playback
Select all elementary streams in a VLC rip will grab all the audio tracks available. The Internal player can switch among them from the OSD but you may get annoyed at having to do this every time. You can trim out the offending tracks permanently with
ffmpeg -i Movie.mpg mv Movie.mpg Movie.mpg.bak mpegdemux --remux --stream 0xe0/0xbd --substream <audio> Movie.mpg.bak Movie.mpg
ffmpeg -i will list out the streams, the stream numbers you want are the numbers in square brackets starting with 0x., they usually start at 0x80. The --substream option to mpegdemux selects which audio streams to include. It can take the form 0x81/0x82/0x83 as a list, 0x81-0x83 as a range or -0x80 as an exclusion.
You will have to rebuild the seektable if using the Internal player.
MythVideo supports the ability to limit what videos maybe viewed without a password/pin. There are 4 different levels that a video/file can be set at. From within the configuration you can select a default level and a password/pin for each level. Any videos/files at or below the current level will show up in the list. Use Video Manger to change the level of any particular video (must be done on a video-by-video case, or with a hack like this one).
MythVideo will only stay at that level until you try to change the level (by hitting keys 1-4 in the Browse or List screens), or exit out of MythVideo to the main frontend menu. Changing to a level which has a password/pin set will require the pin to be entered. MythVideo remembers that you entered the pin for 2 minutes, so once you've entered the pin for a given level, you can freely switch between that level and all lower levels without a pin until that two minutes is up, after which you'll need to enter a pin again to switch to a higher level.
External Player Configuration
To choose an external player (mplayer, Xine, etc.), you will need to delve into your MythVideo setup.
At the main screen, scroll down to Setup, then Video Settings, then Player Settings. Here you'll see a box which contains the command line MythFrontend will launch your video file with. %s is a variable which corresponds to the file path and name of the file you're going to play. All you need to do is edit this command line to run whatever player you like. The %s string expansion appears to be broken in version 0.20; it no longer contains the entire path, but only the file name.
Please note that if you use MythVideo to launch external players, you must have a window manager configured and running so that window focus can change from MythFrontend to the media player. Compatible window managers include those built into KDE and Gnome, Ratpoison, Fluxbox, and I imagine many more.
The default configuration uses mplayer
mplayer -fs -zoom -quiet -vo xv %s
If you have audio sync problems, try changing the audio system to OSS
mplayer -fs -zoom -quiet -ao oss -vo xv %s
You can create a playlist containing a list of video files to play continuously one after another. This is great for music videos at a party or combining movies downloaded in several parts.
There's no way to create the playlist from within mythtv, so you'll have to log in and do it from the shell. Use any text editor to create playlist files with 1 filename per line and use the extension .pls. You can also pipe a directory listing to a file. Mplayer doesn't seem to like spaces in filenames so you'll need to rename files or they will be skipped over. -EDIT- The playlist feature of mplayer chokes on filenames that have escaped spaces. Remove the backslashes from the list of filenames in the playlist by using a text editor like vi and they won't be skipped.
dir * > all_videos.pls
At the main screen, scroll down to Utilities/Setup, then Setup, then Media Settings, then Video Settings, then File Types. You'll need to add a new file association for playlists and provide the command to play them.
Select New, then enter pls (without a period) and select Create new extension. Select the Command box and enter
mplayer -fs -zoom -quiet -vo xv -playlist %s
If you are using xscreensaver you can add the option
to prevent the screensaver kicking in while watching the video. Make sure the default and ignore boxes are not checked.
Add -shuffle after mplayer if you want them played in random order.
Don't forget to run the video manager so MythTV notices the new playlist file. The playlist file will now show up in the list of videos.
While they're playing, use < and > to jump to the previous or next file. If using a remote with lirc, the config commands to achieve this are pt_step -1 and pt_step +1.
To have a playlist dynamically regenerated each time it's played, a small script can be used as the custom command: MythVideo:playRandom.sh
Running man xine from the terminal will get you an exhaustive list of the many options Xine can be run with, but the following is a good default:
xine -pfhq --no-splash
-p specifies "autoplay", f starts in fullscreen mode, h hides the GUI (if you've installed xine-ui) and q means that xine will exit after the video finishes playing, returning you to MythVideo. --no-splash disables the splash screen that Xine usually starts with.
Further Xine Configuration
It seems that xine has a rather annoying habit of reverting back to the default keys even after configuring them, and that several functions overlap each other (the prev/next mrl function and the prev/next chapter buttons are an example). The easiest way to solve this problem is to edit the keymap file ($HOME/.xine/keymap usually) or just use the keymap editor in xine_gui if you have it installed, and set up the keys how you'd like, in my case one for watching vids and another for watching dvds. Then copy the keymap file to something similar to keymap.video and/or keymap.dvd. Then enter this as your default player (using the above configuration as a base).
xine -pfhq --no-splash --keymap=file:/path/to/.xine/keymap.video %s
This tells xine to load the keymap from the specified file. After doing this xine decided to behave and has been working nicely for some time.
Individual videos can be configured using the video manager at Main Screen->Utilities /Setup -> Video Manager.
You can also run specified files with a non-standard command. While in the video manager, if you hit enter on a specific file, you are presented with the settings for that file. The categories here are fairly self explanatory, but in the Unique Player Command box at the bottom you can specify different parameters to launch the file with.
If your movie comes in two or more parts, you can specify the file you always want to play next under File to Always Play Next. For example, if I'm editing "A Film Too Long CD1", I can shift left and right until I find "A Film Too Long CD2" and so on. This will give you seamless playback of your chosen flick.
MythVideo comes bundled with some cute scripts to look up details about your film over the internet. When you're in the Video Manager, hit i to bring up the info screen. Here you'll see an option to Search IMDB. Hit enter, and the script will tootle along over to the Internet Movie Database and retrieve details about the film as well as a poster of it.
Please note that the IMDB script relies on you having accurate filenames; if your film is named "@ f1lm 2 l0ng", the script isn't going to work. In this case, you can either use the Edit Metadata function to rename the movie within MythVideo and then re-attempt the Search IMDB option, or you can rename the file within the actual Linux OS. Alternatively, you can enter the IMDB reference number manually. You can get this number by looking up your film on the IMDB website, and noting the number in the URL that follows the tt. For instance, Akira http://imdb.com/title/tt0094625/ has an IMDB number of 0094625. If you type this into the Manually Enter IMDB # input, the IMDB grabber script will shoot off and grab the data for you.
In case the IMDB grabber script gets confused - sometimes different films have very similar names - the results are returned in order of popularity, as well as having their year of release shown in brackets. This should be enough for you to work out which is the correct entry.
It's also important to note that certain versions of MythVideo have issues when trying to fetch movie information with the included IMDB Script. If you aren't getting the plot, director, ratings, etc, then you are probably going to want to fix this. The steps provided below have been copied from this site. The fix is pretty simple:
First create a backup of the original script
sudo cp /usr/share/mythtv/mythvideo/scripts/imdb.pl /usr/share/mythtv/mythvideo/scripts/imdb.pl-orig
Download the SVN Copy (now in an older Revision 18604)
wget "http://svn.mythtv.org/trac/export/18604/trunk/mythplugins/mythvideo/mythvideo/scripts/imdb.pl" -O imdb.pl
Replace the old script with the new one
sudo cp imdb.pl /usr/share/mythtv/mythvideo/scripts/imdb.pl
Make the new script executable
sudo chmod +x /usr/share/mythtv/mythvideo/scripts/imdb.pl
You should be all set after that.
Have updated link to older revision of imdb.pl, but this section still needs updating referencing the new equivalent Python script.
Custom Movie Artwork
MythVideo looks for artwork downloaded from IMDB in ~/.mythtv/MythVideo. You can put custom artwork here and then in Video Manager->Edit Metadata->Cover Art you can select your custom art from the dialog box.
To play videos go to the Myth Mainpage->Media Library->Watch Videos screen.
The default view is the Folder View. This view can be changed via the on screen menu by pressing the menu button.
Selecting a video will bring up its detailed information. Selecting a second time will launch the video.
Mediashares gives a simple walk through of how to export your media directory so its accessible from your other remote Mythtv systems.
