Make sure we always remove all output frames from the output
frame queue, even if there's no picture.

This fixes (for most practical cases at least) the issue where
the app could hang repeating "can't get output picture" after
stopping playback with omxil video decoding.

In that case, the vout didn't return any picture to write the
decoded frames into, causing the omxil codec to run out of output
buffers, blocking, and thus running out of input buffers, blocking
the decoder thread while waiting for a free input buffer.

Without this fix the second CSA key can not be set, which results
in a stream that is impossible to decrypt.

Tested with:
  cvlc \
    -I dummy -vv \
    --sout '#standard{access=udp,mux=ts,dst=239.78.78.78:5000}' \
    --sout-ts-crypt-audio --no-sout-ts-crypt-video \
    --sout-ts-csa-ck=1111111111111111 \
    --sout-ts-csa2-ck=0000000000000000 \

Maybe it could work with VC-1 Main, but no samples so far

macosx: added 'subsdelay' to the track synchro panel and removed the bogus, non HIG-compliant plus and minux buttons

macosx: implemented drag & drop from playlist to media library and vice verca. additionally, drag from SD to ML or PL is supported. (close #6044)

macosx: removed VLCControllerView, which was superseeded by VLBrushedMetalImageView and VLCThreePartDropView

macosx: refuse file drops on the playlist table if the current root item is neither the local playlist nor the media library

vout_macosx: re-write VOUT_DISPLAY_CHANGE_FULLSCREEN the way it was intended and update the display size correctly, so we get sharp OSD rendering

macosx: fixed appearance issue when collapsing / expanding the playlist while it is empty (close #6382)

macosx: set a sane minimum size for the advanced prefs window, so the options remain useable (close #5994)

Previously, VLC would assume 4/3 picture aspect ratio. That was quite
lame. This patch makes --v4l2-aspect-ratio redundant.

This disables driver-specific modes that VLC would not know about.
This also disables high quality (i.e. still camera) mode since we want
video, as well as other any other future abnormal modes.
