The three attached patches (against 1.1.6) each increase the amount of
debug logging in their respective components. We've found the extra
logging useful when trying to track down faults.
I've split this into three patches to make it easier to apply only some
of our changes.

Comments welcome,

Xv drivers are permitted to return a bigger image than we asked for, to
work around hardware constraints. If this happens, 1.1.6's video_out_xv
cannot deinterlace properly. Fix this by deinterlacing based on the
width of the Xv image; the Xv driver will discard the extra horizontal data.
Without this patch, you get a barber-pole effect if the input video is
interlaced *and* the Xv driver chooses to round up the width of the
requested image.

One can assume that a still frame is to show when there are no more
frames left to display.
The changed code uses _x_query_buffer_usage() to retrieve the number
of frames waiting to be displayed to integrate this information into
the decision.
|
|
There are some situations where bob deinterlacing doesn't make much
sense, as the effect doesn't work for example for slow motion. And
in fast motion mode, the sleep between displaying the two fields
lowers the reachable fast motion frame rate. Another annoying effect
is the reduction in vertical resolution for still images.
The changed code tries to detect such issues and disables bob
deinterlacing for such frames. The detection of still images is
still to come.
|
|
Bob deinterlacing is implemented as showing the top field, sleeping
for half the frame duration and showing the bottom field. Most
drivers tend to synchronize displaying a field on the VBI and thus
displaying a field may take up to half the frame duration in certain
cases.
According to the original code, the sleep took always half the
frame duration and therefore the second field could get displayed
too late. As a result, the driver was syncing to VBI most often,
so that things got even worse.
The changed code now calculates the sleep time in a way that the
second field gets displayed half the frame duration after the
first field. Moreover, it monitors how much time was spent to
display the first field and when this time exceeds 75 % of the
field time (= half the frame time), it skips displaying the second
field, as usually this is an indicator that the driver has no
more frame buffers left. So displaying the second field would just
make things go worse.
|
|
The current implementation keeps references to VO_NUM_RECENT_FRAMES
frames (for deinterlacing), but doesn't make any use of them.
As many XXMC capable devices only supply 8 frames at all, keeping
fewer frames referenced makes more available for decoding and thus
avoids frame drops by keeping the number of frames which are ready
for display more often above frame_drop_limit.
|
|
The current code misses the ability to switch back to an
unaccelerated context, e. g. when previously MPEG2 material
was displayed which is then followed by H.264 material. As
the latter is not handled as XINE_IMGFMT_XXMC there was no
way to leave the accelerated context and therefore the images
did not appear on screen.

This fixes linkage problems for people who want this but don't want X.

Two of the modified files are headers, but each contains definitions as well as
declarations and is only ever used once.

It's still not perfect, but it at least works now.

using hacksaround. Also replace the whole pthread check with an improved macro originally written for XCB, this way it's not going to try linking the fake -lpthread on Darwin, and it also does not force a -I/usr/local/include on FreeBSD. The new macro respects the same variables set by ports, so that it's even more transparent to FreeBSD users.

when using non-pkg-config based discovery of X11 libraries; also check for xext together with x11 with pkg-config. This reduces the list of libraries to add to _LIBADD for video output plugins, and should solve the problems with -lXext being linked in with X disabled.

rewrite libdir, and set AM_LDFLAGS to $(xineplug_ldflags) so that -Wl,-z,defs will be used, for the xine plugins only (libdha's plugins won't be touched by this).
In the case vidix is still getting failures (no way to test here), just set back _LDFLAGS for *that* plugin as they were before, and it would be skipped.

is a good idea to catch common errors. but 5.5MB of useless bloat on
vidix drivers is not worth it.
