Changes between 0.8.6 and 0.9.0

Important notes

This version of VLC contains a new interface for Windows and Linux. This interface lacks a few features that used to be present in vlc 0.8.6:
- "Streaming wizard" and "VLM control". These features will be replaced by a better alternative in the next version. If you absolutely need these features, we advise you to keep vlc 0.8.6
- Similarly, "Bookmarks" will be reintroduced in an improved version at a later point
The default Interface is now Qt Interface on linux and windows.
The default for --sout-keep has changed. It's now activated by default.
The marq, mosaic and logo commands in the rc interface changed. They now require a target name as their first argument. Example:

vlc --sub-filter "marq@test{marquee=Hello}" -I rc <somevideo>

You can then use commands like:

@test marq-marquee Goodbye

These new commands are also available in the telnet interface.

If you want to make it available from other machines, you will have to edit the ".hosts" file.

If you're using the old http interface, it's located in /usr/share/vlc/http/old/.hosts

On Windows they are in C:\Program Files\VideoLAN\VLC\http\.hosts and C:\Program Files\VideoLAN\VLC\http\old\.hosts
On Mac OS X, you can find it in VLC.app/Contents/MacOS/share/http/.hosts and respectively in VLC.app/Contents/MacOS/share/http/old/.hosts

Please use the RTP stream output instead, e.g.:

Old: '#std{access=rtp,dst=239.255.1.2,sap}'

New: '#rtp{dst=239.255.1.2,sap}'
