Hello,

I really enjoy using VLC. It is incredibly flexible and has many ways to be used, although simple in its use !
My 4 kids have a bad habit scratching DVDs (in fact letting them under chairs..), therefore I purchased a big-size HD and backed up DVDs on it, letting them watching movies on TV from the HD.

My TV is connected to a Freebox (ADSL modem from the French ISP Free) that is also able to receive a UDP MPEG-2 TS stream from VLC, and let it display on TV. Moreover, a HTTP browser on Freebox allows me to use the HTTP interface on VLC.

I have no problem for a lot of DVDs that are nicely streamed over the network, but I am stuck on one. The strange thing is that I am able to watch the movie without problem on my PC screen with VLC, but I am not able to stream it ! When inserting the original DVD, I have the same problem : I am able to watch the movie on PC screen using VLC, but I am not able to stream it over the network.
This DVD (Madagascar) is known to be protected by RipGuard, a recent Macrovision protection scheme.

Could someone help me deciphering the VLC error messages below so that I understand what options to add to VLC commande line or the kind of trimming I need to perform on the DVD files ?

Thanks very much in advance for any help.

Some data :
I am using vlc-0.8.4-svn on Windows XP SP2 Professional Edition, on a PC with a 1 GHz processor and 512 Mbytes RAM.

vlc command line executed for streaming is the following :
..\vlc\vlc.exe --extraintf http:rc --rc-quiet --rc-host :8082 --http-host :8081 --http-src=./http_vlc --sout="#std" --sout-standard-access=udp --sout-standard-mux=ts --sout-standard-url=212.27.38.253:1234 --sout-ts-pid-video=68 --sout-ts-pid-audio=69 --sout-ts-pcr=80 --sout-ts-dts-delay=400 --sout-ffmpeg-strict-rc --open=""

This is what I get when trying to stream the movie :

Again, thanks a lot for any indication you may have

If someone with VLC knowledge could have a look on the debug logs of my initial post and tell me why vlc did not stream the DVD... I would be very grateful !
Thanks in advance,

Alexis.

Try streaming, without dvdmenu's option enabled in the Open Disc dialog.

Hello DJ,

Thank you for the advice.
I unchecked DVD Menus button in the Open Disc dialog and checked DVD button instead, but VLC output did not change : I got no streaming for Madagascar.

In fact I use Open Directory dialog box for opening DVDs and streaming works the for all DVDs except Madagascar. But still if I open a VLC media player with streaming disabled, I am able to watch Madagascar on my PC screen.

My guess is that due to DVD protection, there is some desync between video and audio streams that can be overcome when displayed on screen but not when streaming ? But I do not know if the VLC logs (above) really describe this desync or not ? Maybe I am out of scope ?

How are you ripping the DVDs to your hard drive?

I am using DVDDecrypter to rip. I think this is OK (at least in my country) as long as I own the original DVD. My goal in ripping is to protect the DVD from the rough hands of my kids (it is already too late for most of their DVDs that are scratched and cannot be read for some parts).

But the point is that I get exactly the same behaviour when using the original DVD. The original DVD would be played by VLC on PC screen, but not streamed. This is why I think this is somehow related to the RipGuard protection Madagascar is known to be protected by. If someone could explain to me the VLC logs above, it would be great ! If logs with DVD playing instead of HD playing are needed, I can produce them too. They look just the same.
Thanks in advance for help,

Alexis.
