This Widget (base QLabel) is designed to show the cover art. It handles right-click, and show a context menu that has only one entry:

- Download cover art

When the user clicks it, vlc downloads the cover art (or finds it in the cache), and displays it when downloaded

(it was used by net_OpenDgram when no server is specified).

This reverts commit 1a4dc822.
I will backport the proper fix.

It may improve TS clock synchro algo.

DEMUX_GET_PTS_DELAY should returns microsecond.

You should NOT remove caching to PTS to create PCR.
It was probably a workaround for the previous bug. It could explains
the problems with TS over RTP (for TS with small pcr/pts delay that is, not
created by VLC)

Implemented missing DEMUX_CAN_* query.

Crash happens if you do:
 - Play item
 - Activate vfilter
 - Stop item
 - Deactivate vfilter... BooM.

This is a quick fix that does not want to be in master... Proper fix should go to master.

 While it is great for (some) streaming cases it is really wrong for saving
to a file for example and/or without using the gather module.

 If you have read how to use the gather module, you probably have read enough
documentation to add sout-keep...

This is of course NOT a good solution, and it has nothing to do in the interface...
So, either we let it like this, or we implement in the good place (not in intf)
or we remove this option
