  vc1: Do not assume seek happens after decoding

See: 6801eb0aMerged-by: Michael Niedermayer <michaelni@gmx.at>

Fixes Ticket3976
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

The paint_mouse_pointer() code uses XFixes to retrieve the cursor
coordinates, but XFixes gives no information about which screen the
pointer is on; this results in always drawing the cursor on the
captured screen even if the mouse pointer was on another screen.

For example, when capturing from screen 1 (i.e. -f x11grab -i ":0.1")
the cursor was being drawn in the captured image even when the mouse
pointer was actually on screen 0, which is wrong and visually confusing.

It could return NULL if the cursor is outside the screen, the connection
timed out or the system is out of memory.

If a seek is requested before the decoding start there is no
current picture.

The -hls_allow_cache parameter enables explicitly setting the
EXT-X-ALLOW-CACHE tag in the manifest file. That tag indicates
whether the client MAY or MUST NOT cache downloaded media
segments for later replay.

Valid values are 1 (=YES) or 0 (=NO) and the EXT-X-ALLOW-CACHE
will not show in the manifest for other values (or if
-hls_allow_cache is not used.
