ZProcess: Using VLC for DVD transcoder

[mvallevand]

Frank, I don't know if you can interface to vlc but this will create a mvp compatible mpeg from an encrypted dvd D: is my drive dst is the destination. I was using it with mvpmc native interface for a while and it works ok. You can add it as a custom task if it is setup properly.

Code:

vlc dvdsimple://D: --sout=#transcode{vcodec=mp2v,vb=2048,scale=1,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=file,mux=ps,dst="c:\temp\movie.mpg"}} -I dummy --dummy-quiet

Thanks. I'll look into that... I've used VLC in the old ZProcess, might be time again...

That is very slick. I'm hoping to include subtitle support and some over scan underscan support for 4x3 frames too. I think that I gave up on VLC because it was giving me trouble in that regard.

What version of VLC are you running and would consider stable, to recommend to users...

An old copy of ZProcess1, which used VLC, answered my questions


Wow!

Version .9 is not good for this 86i is ok, as are many other older versions.

One thing you might also want to try for fun if you ever use mvpmc is to see how direct streaming works. I could tweak things to give you full vlc navigation to move back and fourth through the file etc.

Here's a dumb example to give you an idea. In mvpmc exit emulation mode to the filebrowser and go to the mvpmc web browser and add an entry an new playlist entry with an url to your server

http://xx.xx.xx.xx:5212

Then save this file as dvd.vlm in the vlc folder

Code:

new mvpmc broadcast enabled
setup mvpmc input "dvdsimple://D:"
setup mvpmc output #transcode{vcodec=mp2v,vb=4096,scale=1,acodec=mpga,ab=192,channels=2}:duplicate{dst=std{access=http,mux=ts,dst=:5212}}
setup mvpmc option sout-http-mime=video/mpeg
control mvpmc play

The run this command line
vlc -I Telnet --vlm-conf dvd.vlm

From the mvpmc file browser navigate to default.m3u and select you new playlist entry.

After you have stop, kill the vlc task.

So that text file would be generated with aspect ratios (overscan ostioning etc) and saved into the VLC folder. And when I I exit and start VLC, it would auto play the DVD?

I think I have that...

How would I be able to do that for Non MPEGS on a case by case. Like in GB-PVR when in Video Library. Not all torrents and rips are the same size and apsect, so it's nice to have ZProcess calculate the dimensions...

Maybe I could selct a video to play in VIdeo Library, ZProcess would do it's thing but also save a customized VLC script saved to VLC folder. I could get out of the video in GB-PVR, go out of emulation mode and start the video again with VLC streaming, but be able to fly around the playback position....

Can you think of any thing else?

[zehd]

Or maybe a PreProcessing command MVPMC could call to ZProcess...

[mvallevand]

Anything that you want as standard parameters could be added on the command line when the session is started. Also there is no need to go out of emulation mode to do this, I would just not be able stream the file via Hauppauge protocol.

I do have a couple of problems using VLC to create a temp MPG for on the fly DVD viewing...

The docs suck.

I'd like to normalize the ac3 audio. The resulting audio is nasty quiet. But that's 'AC3 to 2 Channels' for you...

And supposedly it won't work on a DVD-ROM drive that has been shared to a network... I wonder if there's a workaround for that... (though, I suppose the MVP server should have a DVD-ROM drive, shouldn't it... )
