Hi there Some other VLC problems introduced by Wheezy.A MKV which disables the sound in VLC. I had to restart VLC to get the sound back. Other MKVs works fine.
VLC doesn't do http streams when the http_proxy is configured. Instead of http://Some_Host/Some_File it requests http://Some_Host/ When an IPv6 address is used, http://[IPv6_Address]/Some_File, it bypasses the proxy and works fine.
