d279e12c8f codecparsers: jpeg: fix and optimize scan for next marker code. 
Fix scan for next marker code when there is an odd number of filler
(0xff) bytes before the actual marker code. Also optimize the loop
to execute with fewer instructions (~10%).

This fixes parsing for Spectralfan.mov.

41ed5c0266 codecparsers: jpeg: fix calculation of segment size. 
The size of a marker segment is defined to be exclusive of any initial
marker code. So, fix the size for SOI, EOI and APPn segments but also
the size of any possible segment that is usually "reserved" or not
explicitly defined.

417db39d0d codecparsers: mpeg4: actually return full number of bits of resync marker 
Switch the increment of markersize from when it is used to when it is
returned from compute_resync_marker_size.

This also makes the CHECK_REMAINING in gst_mpeg4_parse_video_packet_header

b14fb383ed Revert "codecparsers: remove ignored increment of return" 
This reverts commit 916b954315.

Clearly something else was intended, and it also makes
more sense to add the extra bit. The resync marker is
N zero bits plus a 1 bit, and the pattern/mask needs to
be run on N+1 bits too.

(Even after the rever the code doesn't do that of course, so
it still needs to be fixed differently.)

b395c055eb videoaggregator: add "ignore-eos" property for input pads 
When set, it causes videoaggregator to repeatedly aggregate the last buffer on
an EOS pad instead of skipping it and outputting silence. This is useful, for
instance, while playing back files seamless one after the other, to avoid
videoaggregator ever outputting silence (the checkerboard pattern).

It is to be noted that if all the pads on videoaggregator have this property set
on them, the mixer will never forward EOS downstream for obvious reasons. Hence,
at least one pad with 'ignore-eos' set to FALSE must send EOS to the mixer
before it will be forwarded downstream.

1a98face84 gl: win32: do not call SetParent in release_parent_win_id() 
When called from gst_gl_window_win32_close(), internal window
could not exist, and if it does it's going to be destroyed just
after that anyway. Also it causes window_proc() to be called
and crash because it gets a NULL context.

When called from gst_gl_window_win32_set_window_handle() we are
going to set another parent anyway, and it's probably better to
reparent directly instead of passing by a NULL parent which could
cause the internal window to popup briefly.

247697ce62 gl: win32: fix crash when finalizing GstGLContext 
gst_gl_context_finalize() is calling gst_gl_window_win32_quit()
which was posting a message. But then window_proc takes window's
context and get a NULL.

Now that we've got a GMainLoop we can do like other backends and
simply call g_main_loop_quit().

This also remove duplicated code to release the parent window and
potential crash there because parent_proc could be NULL if we never
created the internal window. That could happen for example if setting

which can be different for each stream.

7a3b34de79 glfilter: Don't chain downstream pool 
Chaining a downstream pool would lead to two owner of the same
pool. In dynamic pipeline, if one owner is removed from the pipeline
the pool will be stopped, and the rest of the pipeline will fail
since the pool will now be flushing. Also fix proposed pool caching,
filter->pool was never set, never unrefed.
