wm4 2483dab54d TOOLS/stats-conv: rewrite for pygtgraph
matplotlib is pathetically slow, which makes using stats-conv.py to view
dumps longer than a few seconds a huge pain.

pyqtgraph is slightly faster than matplotlib. Other than that, it seems
to be worse in every aspect (at least for plotting), but such is life.

wm4 73ea0ddc08 TOOLS/stats-conv: more improvements
Add an explicit "signal" event type, because the implicit one was
confusing.

Don't rescale the Y axis of the second graph, it was nonsense.

Make the legend for the second graph separate (and cleanup the code
creating the graphs).

wm4 487208b2e1 TOOLS/stas-conv: add timed value event type 2015-01-02 19:27:07 +01:00
wm4 83349a0e73 TOOLS/stats-conv: better output
Sort the legend by the used y value of binary events/signals, add a way
to filter branches (although that requires editing the script), and use
the full screen if the second subplot is not used.

wm4 3c07e86fd3 TOOLS/stats-conv.py: improvements
This is still pretty useful for debugging timing-dependent things.

wm4 cc94436c5b TOOLS/stats-conv: draw playloop and AO thread events separately
Use for all AO thread events y=0.5, while playloop events remain at y=1.
This makes the graph easier to read.

wm4 9dba2a52db player: add a --dump-stats option
This collects statistics and other things. The option dumps raw data
into a file. A script to visualize this data is included too.

Litter some of the player code with calls that generate these
statistics.

In general, this will be helpful to debug timing dependent issues, such
as A/V sync problems. Normally, one could argue that this is the task of
a real profiler, but then we'd have a hard time to include extra
information like audio/video PTS differences. We could also just
hardcode all statistics collection and processing in the player code,
but then we'd end up with something like mplayer's status line, which
was cluttered and required a centralized approach (i.e. getting the data
to the status line; so it was all in mplayer.c). Some players can
visualize such statistics on OSD, but that sounds even more complicated.
So the approach added with this commit sounds sensible.

The stats-conv.py script is rather primitive at the moment and its
output is semi-ugly. It uses matplotlib, so it could probably be
extended to do a lot, so it's not a dead-end.
