When we have a multi-stream (i.e. audio and video) input and the demuxer
adds/removes pads for a new stream (common in a mpeg-ts stream when the
program stream mapping is updated), the algorithm for EOS handling was
previously wrong (it would only drop the EOS of the *last* pad but would
let the EOS on the other pads go through).
The logic has only been changed a tiny bit for EOS handling resulting in:
* If there is no next group, let the EOS go through
* If there is a next group, but not all pads are drained in the active
group, drop the EOS event
* If there is a next group and all pads are drained, then the ghostpads
will be removed and the EOS event will be dropped automatically.
Make sure decodebin1 doesn't try to plug the same parser twice
in a row (so we can change all parsers to accept parsed input as
well without breaking applications still using the old decodebin1
element).
This allows us to make parsers accept both parsed and unparsed input
without decodebin plugging them in a loop until things blow up, ie.
without affecting applications that still use the old playbin or the
old decodebin.
(Making parsers accept parsed input is useful for later when we want
to use parsers to convert the stream-format into something the decoder
can handle. It's also much more convenient for application authors
who can plug parsers unconditionally in transcoding pipelines, for
example).
Add a flags property and two flags to allow one to disable the
conversion elements within encodebin. Doing so insists that the
uncompressed input to encodebin for the appropriate stream type is
sufficient to meet the caps requirements of the encoders, muxers and
encodebin target.
This is mostly beneficial to bypass slow caps negotiations in the
conversion elements.
Caps returned from gst_pad_peer_get_caps_reffed () may not be writable.
If they are not is should cause an assertion in gst_caps_merge (),
however, sometimes assertions are disabled in binary builds of -base and
it's safer to just be sure the caps are writable. Also, check that the
reffed caps pointer is not NULL.
The length check isn't sufficient, an source might
report the correct length, but then still fail to
read the requested number of bytes for some reason.

This is an ad-hoc release that is almost identical to 0.10.34:
* work around GLib atomic ops API change
* don't use G_CONST_RETURN in public headers
* subparse: typefinding fixes for subtitles in non-UTF8 charsets
This decreases the number of buffers held on each pad by one,
eliminating next_buffer. Simplifies the logic by relying solely
on CollectPads to let us know when a pad is in EOS. As a side
benefit, the collect pads related code is structured more like
other CollectPad users.
The previous code would occasionally mark the wrong pad as EOS,
causing the code to get in a state where all the streams were
finished, but EOS hadn't been sent to the source pad.
The testchannels audio test program is using -lgstaudio-0.10 to link
with libgstaudio which won't use the gstaudio library that was just
built but the one from the system. This is an issue since it means
we won't be testing the code from the current source tree, and it
also breaks the build when building on a system which don't have
a libgstaudio yet.
