This is done to better diagnosticate misconfiguration of libvlc path.

Spotted by Dominique Leuenberger. Thanks.

This works around GNU coreutils nohup not working with VLC.

It is used in many places, namely all X11 plugins _except_ the video
display ones. So it did not make much sense to keep it there IMHO.

This reverts commit 1e56f368.

Noticed by GBeauchesne.

PIX_FMT_DXVA2_VLD is not yet in official ffmpeg.

This fixes the opengl "vout display" on Mac OS X.

Note: cc_pts/dts are still set to 0, I can't tell if this value is the
starting timestamp, or if it means the timestamps are not valid.

Better understanding on how pf_get_cc and packetizers are called in
src/input would clarify (fenrir?)

To build the old version, you have to pass the --force-deprecated option to the setup.py script.

* set a meta (without changing the file)
* save all meta to the file

Note, the opengl output is still broken on Mac OS X, in the way that no picture are rendered.
