Butw ithout it, the layout of multichannels audio are probably wrong.

Maybe we should split encoders per ES type?

These calls have been replaced by vlc.playlist.items.* calls.

It is up to the access to refuse if it can't.
Anyway, the check was only for one path of a seek command (when using
stream_Read( NULL, size)).
This partially revert fc9f8518, please report any breakage.

It avoids loosing the first packets (audio/video).

It will help the buggy transcode stream_out module.

This should only be used if VLC deadlocks, or takes an awfully long time
to clean up. That will let VLC be killed as with the older signals
handler.

 It will prevent a useless chroma conversion for the vout using it
(x11/xvideo at least).
 It is not perfect are they are not exactly equal, but in the current
state, I think it is the best workaround.

This makes decoding faster but could lead to errors.
