This is supported be a few media players. XBMC, VLC come to mind. I have a huge media server and it would nice to be able to not have to extract the movies to watch them.

This feature is definitely a must

Oh and just to add, XBMC and others actually do not support playing content from compressed rars but just stuff that has been packed with the "store" method. So the rars are not uncompressed, they are just mounted on the fly and then they can be plaid.

I know there do exist some libraries to mount rar files so it shouldn't be too hard to implement this feature.

Actually, this isn't hard to do, at least if you're running Linux. You can probably do something similar on Windows too, but I don't know how.

Install unrar
Install ffmpeg
Make symbolic links to these in the Subsonic transcode folder.
Log in to the Subsonic interface as an admin.
Add a new transcoding in Settings -> Transcoding -> Add transcoding.
Convert from: rar
Convert to: flv
Step one:

Code: Select all

unrar p -inul %s

Step two:

Code: Select all

ffmpeg -ss %o -i pipe:0 -async 1 -b %bk -ar 44100 -ac 2 -v 0 -f flv -vcodec libx264 -preset superfast -threads 0 -

Go to Settings -> General and add " rar" to Video files to make it recognize the .rar files.

You might want to add " -s %wx%h" in step two (before the last dash (-)) if you're using a mobile device, to lower the resolution. The problem with this is that it seems to screw up the aspect ratio, but that's another thread's problem.

This extracts the rar archive, outputs the content to stdout, pipes it to ffmpeg which transcodes it and output the finished video to the player.
It will probably work with compressed archives too, I haven't tried.
However, you can not skip in the video. You have to start at the beginning each time.
You can use Subsonic's drop down menu to skip, but this takes some time, and I suspect it transcodes everything from the beginning up to that point. Heavy load on the server.

Happy videoing!

Edit:
It seems you can skip in the video, if you don't skip too far.
As soon as you start playing, the server starts transcoding, and don't stop until everything is done. As long as you don't jump further than the transcoding has gotten, it works.
I also added " -s 640x360" to my step two, to lower the resolution and set the aspect ratio to 16:9, which most my videos are.

Excellent wizardry here

Thanks Zmegolaz

this would be a killer feature!

I've tested Zmegolaz's guide in Windows and got it working.

Just go to http://www.rarlab.com/rar_add.htm and download "UnRAR for Windows". Extract the downloaded file to your install-path/transcode, mine is "C:\subsonic\transcode", so that unrar.exe is added to your transcode-folder.
After that you just follow Zmegolaz's guide.

Works perfectly, it just takes a lot of performance while transcoding a 1080p movie.

If you are having any trouble with this on windows and can not figure it out, rename unrar.exe to un-rar.exe

That was all it took for me, Also, on the up dated versions of ffmpeg (at least on windows) you can not use pipe:# for the input, you just have to use -

Code: Select all

ffmpeg -ss %o -i - -async 1

you should see something like this in the subsonic web log

Code: Select all
