[vlc-devel] Demux/Stream pause state propagation

On pause, the input does notify new state to demux or its slave stream:
if( p_demux->s != NULL )
i_ret = stream_Control( p_demux->s, STREAM_SET_PAUSE_STATE, true );
i_ret = demux_Control( p_demux, DEMUX_SET_PAUSE_STATE, true );
The problem being, for example, adaptive, the slave stream is a fully
read manifest, does exist, and will always succeed. The demuxer will
never get notified.
I believe notifying both by default would raise some new issues.
I see three options then:
* Have the streams fail on SET_PAUSE_STATE when they reach eof.
Probably incorrect as they can still seek.
* Have new demux flag for routing this control.
* Add new signal/control to notify demuxer its stream handled pause.
