No need for fflush(stderr) when it's already unbuffered by default.
According to setvbuf(3):
Normally all files are block buffered. If a stream refers
to a terminal (as stdout normally does), it is line
buffered. The standard error stream stderr is always
unbuffered by default.

Making things a bit more consistent
|
|
Since the frame timer implements a frame counter, and that frame count
is propagated through the get->encode pipeline for samples that get
through, any missed frames are noticed and dealt with making it not
lossy from the point of the timer down to the encoded stream in terms
of number of frames.
It's certainly lossy in terms of the contents of those frames, but
synchronization is all about the temporal domain and as long as the
frame counts all make it into the stream as frames, we can account
for them at the timer in terms of avd.
This in combination with the other commit moving the audio side of
avd maintenance immediately upon capture into the raw buffer, shrinks
the variable capacitance separating the audio timer and the frame
timer to virtually nil. As a consequence, the frame timer can now
be much more accurate in terms of how much longer/less to sleep or
if a frame should be dropped to get the timer caught up.
When avd was being maintained at points far removed from the actual
things they represented there was too much elastic capacitance in
there for sync_streams() to inform its adjustment accurately.

This brings the !--on-the-fly-encoding mode up to speed.
The cached file header loses the total_frames counter, as the
capture_frameno already represents this.
Dropped frames are detected by simply looking at the difference
between the previous capture_frameno and the current one. This
simply gets passed to the encoder as a n_frames count so theora
can duplicate the frames as needed.
This was being done manually before by looking at the frameno and
total frames in each header and maintaining separate counts for
"extra frames" "missed frames" etc, and resubmitting entire
frames multiply for encoding dropped frames.
So a chunk of code has been thrown out from rmd_load_cache.c, and
some general cleanups have occurred there as well.
I also needed to add more locking around pdata->avd accesses.

Now users can easily differentiate which rmd subtasks are
busy by using top-like tools in show-threads mode.
Also aids in troubleshooting...

This restores the recordmydesktop/ subdir as root from the mirror I
cloned by fork from.
I have no particular interest in the gtk/qt frontends and it doesn't
appear they were part of a single tree in the past. But I will
probably preserve backwards compatibility of the cli so they can
continue to work with this fork installed.
