Enhance scanning of video library to accomodate DVD backups

[peter_greis@…]

Currently MythVideo? only looks for files with a set suffix to determine playback attributes (such as the player used). These in include .vob .mpg .avi and others.

I would suggest adding the scanning of directories to determine if these are direct copies of DVDs. For example, of the directory "foo" contains the directories "AUDIO_TS" and "VIDEO_TS", then it is most likely a DVD backup. If added to the list of videos, then it could be played back with "xine --no-splash dvd:/%s/".

At the moment, hacking the database directly seems to be the only way of enabling this bit of functionality.

Why not create an .ifo extension and having that be the basis for figuring out if it is a DVD copy?

[peter_greis@…]

Using dvd backup, I don't get an .ifo extension. Perhaps there is a better way ?

I took a look at the code. As a special case it probably isn't that hard to code up. There is an if clause in the buildFileList which recurses if it finds a dir. One could insert some code there to check the name of the dir (if VIDEO_TS, then add to m_VideoFiles, if not go down the directory looking for video files. Then put in a VIDEO_TS entry in the extensions table in dbcheck.cpp and see if it works out.

The one issue I haven't figured out is that all of the extension files use the same playcommand. But dvd copies would require a different playcommand by default. It could be changed manually once mythvideo is up, but that is a little cumbersome.

The other thing I don't like is that the dvd copy search is hardcoded in the videoscan class instead of having a little more general solution. I wonder if coding it the easy way, if it would be accepted?

add dvd copy playing to mythvideo

The newly attached patch compiles but has not yet been tested. I intend to test it tonight. It should give a rough of idea of how the support could be implemented. I definitely appreciate any feedback on the patch anyone wants to give.

Donavan, what do you think of this?

[peter_greis@…]

I have patched my 0.18.1 source and tested this. So far it works flawlessly using "xine -pfq --no-splash dvd:/%s/" for playback. It is really nice to have our video library finally integrated into MythTV.

Many thanks,

(In [7388]) This commit looks a lot bigger then it is.

Close #248 by applying (and fixing) the patch contained therein. Note to submitter: Tabs not spaces, when modifiying dbcheck.cpp you need to bump the schema number and make your changes not change an old schema.

Note: The "video_ts" check was removed it's _always_ "VIDEO_TS" otherwise it's not a DVD.

This also adds a default play commands for ".iso" to match the one for "VIDEO_TS".

The remainder of these chnages are const correctness and formatting changes.
