Otherwise baseparse will consider empty streams to be an error while
an empty stream is a valid scenario. With this patch, errors would
only be emitted if the parser received data but wasn't able to
produce any output from it.
This change is only for push-mode operation as in pull mode an
empty file can be considered an error for the one driving the
pipeline
Includes a unit test for it

Adds API to get or peek a sub-reader of a certain size from
a given byte reader. This is useful when parsing nested chunks,
one can easily get a byte reader for a sub-chunk and make
sure one never reads beyond the sub-chunk boundary.
API: gst_byte_reader_peek_sub_reader()
API: gst_byte_reader_get_sub_reader()
Adds gst_byte_reader_masked_scan_uint32_peek just like
GstAdapter has a _peek and non _peek version
Upgraded tests to check that the returned value is correct in the
_peek version
API: gst_byte_reader_masked_scan_uint32_peek

Adds a utility struct that is capable of storing and aggregating flow returns
associated with pads.
This way all demuxers will have a standard function to use and have the
same expected results.
Includes tests.

Keep it simple. Likely also makes things easier for bindings,
and efficiency clearly has not been a consideration given how
the existing code handled these lists.
In order to be deterministic, multiple waiting GstClockIDs needs to be
released at the same time, or else one can get into the situation that
the one being released first can add itself back again before the next
one waiting is released.
Test added for new API and old tests rewritten to comply.
Store the eos event seqnum and use it when creating the
new eos event to be pushed downstream. To know if the eos
was caused by the eos events received on send_event, a
'forced_eos' flag is used to use the correct seqnum on
the event pushed downstream.
Useful if the application wants to check if the EOS message
was generated from its own pushed EOS or from another source
(stream really finished).
Also adds a test for this

Baseparse stores buffers for reverse playback to push on the next
DISCONT, the issue was that it wouldn't ever check for a discont
on passthrough mode as it skips all real parsing. This test
was create to verify this issue and prevent it from happening again

pop() in collected callback.
There were three threads in the test cases that hanged: the test thread and two
threads that push buffers. Each thread push one buffer on one pad. There are
two pads in the collectpads so the second buffer will trigger the
collect-callback.
This is what happens when the hang occurs:
The first thread pushes a buffer and initializes a cookie to the value of a
counter in the collectpads object and waits on a cond for the counter to change
and for someone to consume the buffer (i.e. _pop() it).
The second thread pushes a buffer and calls the collected callback, which
signals the cond that the test thread is waiting for.
The test thread pops both buffers (without holding any lock). Each call to
_pop() increases the counter broadcasts the condition that the first thread is
now waiting for. It then joins both threads (hangs).
The first thread wakes up and returns, since its buffer has been consumed.
The second thread starts executing again. When the callback, called by the
second thread, has returned it initializes a cookie to the value of a counter,
which has already prematurely been increased by the test thread when it popped
the buffers, and wait's on a cond for the counter to change and for someone to
consume the buffer (i.e. _pop() it). Since the buffer has already been poped
and the counter has already been increased it will be stuck forever.

We previously forgot to initilize the amplitde property to the default and thus it was 0.0. Therefore a default lfo controlsource returned a series of 0.0 and the test was asserting on that.
