I don't understand why the test would be needed, you do receive data
only if the ES is selected.

This was broken after the extension merge.
Close #3665

I highly doubt that the osd register/clear functions are usable...

It removes two broken vlc_object_find(INPUT, PARENT) and fixes input
attachements support when the vout is reused.

It allows to retreive input attachments.

spu_sys_t::i_channel is not equal to the number of currently used
channels but t is equal to the number of reserved channel since the spu
creation.

Should Fix #3672

Sorry for last commit which was a little retarded

Seems that maxrate needs somekinda exponential function from bitrate (comparing
ffmpeg's libvpx presets) and cbr isn't something you likely will get out of this.

This reverts commit a2770977.

They are only ever used if there is an explicit dst

 This avoids the potential deadlock introduced by
[38ed2e8e] when it is called inside
an event emited by the vout.

This reverts commit 38ed2e8e.
It is not complete.

5cc3984f was too strict, and for baseline it
should be only cosmetic change.

libx264 changed default to normal in that build too, also change logic
littebit so b-pyramid selection works better.
