[all variants] mplayerstart - my resumable/tv-out wrapper script

[IgnorantGuru]

Updated: Nov 10, 2009 - Updates to the mplayerstart script can now be found at
http://igurublog.wordpress.com/downl...-mplayerstart/
The versions below are outdated.


Here is an updated version of the mplayerstart script that adds some functionality to the previous one posted here. I'm sharing this here in case others want to use it, or use bits of the code in their own scripts.

mplayerstart is a wrapper script for mplayer which allows the user to resume playback of a previously played file, supports a tv-out mode, disables the KDE screensaver, and a few other things. This version adds a check to see if KDE is running, kmix volume level restoration for each resumed file, support for resuming audio files, automatic playback of the last played file, and acceptance of .resume files on the command line.

Just save this bash script, make it executable (chmod ugo+x mplayerstart), and use it to open media files. If you make an application shortcut to it or add it to the K menu, you can then associate it with avi and other media files in the file manager. Then you can just click on the movie or music file to have resumable playback (very slick).

The only thing this script requires is a folder to store the resume files (a few bytes each) and to temporarily store mplayer console output (which can be a few dozen MB, and is deleted when playing the movie is finished). By default, the script uses the folder ~/.mplayerstart/ for this data.

What mplayerstart does:

* This version first checks to see if KDE (kdesktop) is running. If it isn't, it skips the KDE features automatically.

* mplayerstart plays the media file specified, and when you quit mplayer, saves a .resume file which records where playback was stopped, as well as the kmix volume levels in use when playback was stopped. mplayerstart also disables the KDE screensaver while playing video files.

* The next time mplayerstart opens a file with the same name as the above media file (regardless of location), it can resume playback, and also set the kmix volume levels to their last used level for this file.

* mplayerstart can also automatically resume the last played file.

* When using the --tv switch, mplayerstart will create an X :1 session and send mplayer's output there, which is useful for NVidia (and other?) video cards with TV-Out. Just set up your xorg.conf file as described here: http://en.wikibooks.org/wiki/NVidia/TV-OUT

Usage:

mplayerstart --resume movie.avi

plays the movie from the resume point (if any) and creates a new resume point. If you save the above command (mplayerstart --resume) as an application shortcut or add it to the K menu, you can then associate it with avi and other media files in the file manager for one-click resume.

mplayerstart movie.avi

If you leave out the --resume switch as shown above, mplayerstart will begin playback at the beginning of the media file and will create a new resume point when finished.

mplayerstart --resumelast

plays the last played media file from the resume point (if any) and creates a new resume point. If you save the above command as an application shortcut or add it to the K menu, you can then associate it with a keyboard shortcut (I use Windows-R) to quickly resume playback.

mplayerstart movie.resume

passes a .resume file for playback. If you associate .resume files with the above command, this allows you to browse the folder of resumeable files (found in ~/.mplayerstart/ by default) and click on a .resume file. If mplayerstart can't find the media file in it's last known location, it will search up to two folders recursively (configure these folders in the script).

Notes:

* mplayerstart plays video files in full screen mode without a GUI. To quit playback press 'q'. For other keyboard shortcuts consult 'man mplayer'.

* Audio files are played back in GUI mode. When the audio file is done playing, press 'q' or close mplayer. The .resume file will not be saved until you quit mplayer.

* You can customize the location of mplayerstart's .resume files in the script at the top of the file (just load the script into a text editor).

* After playback, mplayerstart will not re-enable the KDE screensaver if other mplayer's are still running.

* This new version of mplayerstart will read the .resume files created by prior versions, but will save .resume files which are NOT compatible with the prior version. You may want to backup your resume folder before testing this version.

Tips:

* If you want to quit mplayer without saving the resume point, press Page-Up repeatedly until mplayer quits. (PageUp fast-forwards 10 minutes - thus the end of file will be reached and no resume point will be saved.)

You can copy and paste it into a text editor or I have attached it as a txt file.

I just edited the script above to correct one issue. If you're interested in the details...

I noticed that if the movie was playing for awhile, when mplayer quit it took a long time for the script to finish. The result was that if you started the same movie before it finished, it appeared the resume was not working correctly. The problem was the tail command - for some reason it wasn't just outputing 10 lines. I added a --bytes=350 to the tail command and that appears to have corrected this issue.

[IgnorantGuru]

I have modified the original post and script above with an improved version of mplayerstart. I've been using it successfully for awhile but please let me know of any issues you encounter.

[IgnorantGuru]

Updated for KDE4 - tested on Kubuntu Intrepid beta.

I'm not using it but I gotta say this is a great script. Well put together. Didn't know how to suspend the screensaver before in KDE from the command line so I appreciate it.

Thanks - glad you found it. KDE4 gave me more of a problem stopping the screensaver - couldn't get it to work. So I simulated user activity instead for now. These two scripts work for both KDE3 and KDE4 for stopping and starting the screensaver. (the saver-control script calls the saver-suspend script in the case of KDE4) These use the same method as mplayerstart. If anyone knows how to do it properly in KDE4 please let me know.

script "saver-control":

#!/bin/bash

if [ "$1" != "false" ] && [ "$1" != "true" ]; then
	echo Usage:
	echo saver-control false      disable KDE screensaver
	echo saver-control true       enable KDE screensaver
	exit
fi

if [ "$1" == "false" ]; then
	msg="Screensaver DISabled"
else
	msg="Screensaver Enabled"
fi

Below is v1.3.0 of mplayerstart. This works a little differently with the TV. Instead of creating a new X session, it uses xinerama screen #2 for the TV output, which seems to work more conveniently for KDE4. So this assumes you have xinerama enabled in xorg.conf, and that screen 2 is your TV. It can also use a separate X screen instead of xinerama if you change the tvdisplay variable at the top as shown in the example. This version does not create a new X session as v1.2.0 did, but you can paste in the code from that version above if you want it to do so.

Also, with this TV setup, mplayerstart can now create resume files when playing in TV mode.

There are also a few other changes...

There are some additional command line options for controlling TV mode. These are useful when bound to shortcut keys. For example, on my system Win+T sets 'tvonce' (play the next video on the TV), Win+Shift+T sets TV mode off (play videos on computer screen), and Win+Ctrl+T sets TV mode on (play all videos on TV). (If TV mode is on, output will be sent to xinerama screen 2 every time mplayerstart is run, even without '--tv', or only once if --tvonce was set. If TV mode is off, the xinerama screen 1 will be used unless '--tv' is specified.)

Also, when playing VOB files, it will now automatically choose the english (en) audio track.

I think those are the only changes from 1.2.0. This version uses the same .resume file format as 1.2.0. The argument parsing is still clumsy in that it requires all TV options to be first on the command line. That should be rewritten (the script has outgrown the original simple parser), but for now just be sure any --tv... options precede everything else, and options preceed the filename.

Version 1.3.1 and future updates to this script are now posted to my blog at
http://igurublog.wordpress.com/downl...-mplayerstart/

[IgnorantGuru]

Version 1.4.0 of mplayerstart is available. This update adds more flexibility for various TV display setups, including Xinerama, separate X displays, and once again the ability to xinit a display just for mplayer. This also adds an “auto” tvmode which uses the current display for playback. Also, mplayerstart now stops the X, KDE3, KDE4, and Gnome screensavers during playback. Plus, mplayerstart pops up dialogs using either Xdialog or kdialog, to give feedback on functions like rewind. The volume level restoration code has also been rewritten to use amixer, which should be more portable.
