3edf390b4c videorate/videoscale/audioresample: Ensure that the caps returned from fixate_caps() are actually fixated
If there is some other field than the ones we care about left and not
fixated yet then basetransform will just error out. So instead just pass
the result through gst_caps_fixate() in the very end.

bf0cffc474 audioresample: Drain resampler and reset timestamp tracking on stream-start event too
And also reset timestamp tracking on EOS events as more data might come
afterwards with a new stream-start event. This keeps the code the same.

6d423cbba2 audioresample: Drain the resampler and reset timestamp tracking on caps changes
Especially when changing the sample rate our timestamp tracking will be
completely off, but even otherwise we would usually lose the last few
samples if we don't drain here as the resampler gets reset if anything
but the sample rate changes.

This is usually not a problem as the first buffer after a caps event
usually has the discont flag set, but can cause problems if
 - the caps event is followed by a segment event, which then causes
   draining according to the new sample rate
 - the caps were changed because of rengotiation due to a reconfigure
   event and there is not discontinuity from upstream

In both cases we would output buffers with completely wrong timestamps.

5c4f4ac1bd Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

c1cb395f66 audioresample: after a reset, recalculate the ouput size
After we reset the resampler, there is no history anymore in the resampler
and the previously calculated output size is no longer valid.
Recalculate the new output size after a reset to make sure we don't try
to convert too much.

a636c39638 audioresample: Try to prevent endless looping
Speex may decide not to consume any samples because it can't write any. I've
seen a hang during draining caused by the resample loop never terminating.
In that case, resampling happened as normal until olen was 0 but ilen was
still 1. _process_native then reduced ichunk to 0, so ilen never decreased
below 1 and the loop never terminated.

Instead of reverting 684cf44 ({audioresample: don't skip input samples),
break only if all output samples have been produced and speex refuses
to consume any more input samples.

684cf44ee3 audioresample: don't skip input samples
when downsampling, the output buffer can be filled before all the input
samples are consumed.  this is correct:  when downsampling, several input
samples are needed for each output sample, so when only a small number of
input samples are available the number of output samples produced can be 0.

the resampler, however, was discarding those extra input samples instead of
clocking them into its filter history for the next iteration.  this patch
fixes this by removing the check that the output buffer is full.  the code
now always loops until all input samples are consumed, and relies on the
calling code to have provided a suitably sized location for the output.
note that there are already other checks in place in the calling code to
ensure that this is the case.
