fab2d6d60c audiorate: Update next_offset per rate change
To support runtime audio samplerate change, re-calculate next target offset
per caps. Calculating the next buffer offset using the previous
offset seems to be tricky and rounding error prone.

b4e37d8a4b xvimagepool: Update size, stride, and offset with allocated XvImage
Memory layout of XvImage might be different from that of GstVideoInfo.
If so, the image size, stride, and offset would be wrongly informed.

89f613abf5 audio-buffer: Don't fail to map buffers with zero samples
Instead initialize the map infos, etc to NULL like gst_buffer_map()
would be doing on a zero-sized buffer.

95abc6c263 gldownload: Fix renegotiation loop
When DMABuf was tried, we would renegotiate back and fourth between
DMABuf and system memory if the export failed. This would happen for
every single frame.

This patch introduces try_dmabuf_exports boolean, which is unset when
an export failed. This boolean is then put back to TRUE when upstream
pushes new caps, or downstream pushes a reconfigure event.

a09674dd6d gldownload: Refactor download mode selection
This introduces an enum in order to cleanup how we select the
transfer mode. It also fixes the case where we callback to PBO but
we didn't execute the PBO. That was not causing any issue, just that
the processing latency would be delayed to the next element, which
can be confusing.

9870783f01 eglimage: Fix extension names in dmabuf import check
There was a typo in the extension name which resulted in the modifiers
to never be set when doing DMABuf import. That triggered the modifiers
lookup in Intel driver, which was in fact hiding bugs in the gldownload
to glupload path when doing DMABuf.

Note, this changes breaks pipeline the following pipeline on Intel and
some other drivers:

  gltestsrc ! gldownload ! video/x-raw\(memory:DMABuf\) ! glimagsink

A fix for this was added to Mesa recently:

747ae7d769 gldownload: Wait on sync meta if any
This is possibly not strictly needed when pixels are being downloaded to
CPU memory, but would cause issue when exporting DMABuf, as the data may
not be yet ready when the DMABuf reaches the consumer.

494ee67446 playbin: Handle error message with redirection indication
There are in the wild (mp4) streams that basically contain no tracks
but do have a redirect info[0], in which case, qtdemux won't be able
to expose any pad (there are no tracks) so can't post anything but
an error on the bus, as:
  - it can't send EOS downstream, it has no pad,
  - posting an EOS message will be useless as PAUSED state can't be
    reached and there is no sink in the pipeline meaning GstBin will
    simply ignore it

In that case, currently the application could try to handle that but it
is pretty complex as it will get the REDIRECT message on the bus at
which point it could set the URL but playbin will ignore it, as
it will only be for the next EOS, it thus need to set the pipeline to
NULL (READY won't do as it is already in READY at that point). And it
needs to figure out the following ERROR message on the bus needs to be
ignored, which is not really simple.

The approach here is to allow element to add details to the ERROR
message with a `redirect-location` field which elements like playbin handle
and use right away.

We could also use the element 'redirect' message in playbin, but the
issue with that approach is that the element will still emit the ERROR
message on the bus, leading to wrong behaviour. That can't be avoided
since in the case the app/parent pipeline is not handling the redirect
instruction, the ERROR message is necessary (and there is no way to
detect that the message has been "handled" from the element emitting the
redirect).

3b552cc05a display: add a specific lock for the list of windows
It's either this or replacing all the object lock usage in gldisplay
with a recursive mutex which is not backwards compatible

The failure case is effectively:
1. The user has locked the display object lock
2. a glcontext loses it's last ref and attempts to quit the window
3. gst_gl_window_quit() attempts to remove the window from the display
4. gst_gl_display_remove_window attempts to take the display object lock

The only concern with changing the locking for the window list in the
display is that gst_gl_display_create_window() has documentation requiring
the object lock to be held which must continue to work correctly.

a724f9ddfb encodebin: Ensure that a single segment is pushed into encoders
Following the [design document] encodebin needs to handle sources that
output multiple streams, for that purpose and to make it simpler,
we ensure that a single segment is outputted to the encoders by using
an `identity single-segment=true` at the beginning of streams chains.

Added API to enable or disable the use of that new feature.
Added support for the encoding profile parser for that new property,
keeping backward compatibility

33acf73334 audioconvert: Fixed changing mix-matrix at runtime
Setting the property again after it had already been set ran
g_value_unset() but did not initialize it again to g_value_copy() failed
afterwards. Removed the unset as cleanup is done implicitely from
g_value_copy().

Changing the mix-matrix property did not trigger reconfiguration of the
caps, this has been added.

If the matrix is set to an empty matrix, instead of copying this the
matrix is simply disabled by setting mix_matrix_is_set (formerly
mix_matrix_was_set) to FALSE so the mix-matrix is ignored from now on.

c363747251 videorate: Fix max-duplication-time handling
Previously this would've only set discont=TRUE and then for all future
buffers simply returned immediately.

Instead we also need to
  a) drain previous input until its buffer time
  b) update next_ts and base_ts accordingly for the gap
  c) actually store the new buffer after the gap so it can be used in
     the future and so the old buffer before the gap is gone

Also update the unit test accordingly so that it actually tests for this
behaviour. Previously it only tested that after the gap we got no output
at all.

166f979761 video-scaler: Ensure we're always using the correct lines for scaling in gst_video_scaler_2d()
Especially for interlaced input make sure to
  a) never mix both fields
  b) never read lines after the end of the input frame
  c) allocate enough space in the temporary lines to not write outside
     the allocated memory area

This fixes various memory corruptions and rescaling artefacts.

At the moment, we only posted QoS messages when frame_drop() was

frames. We also emit a warning on drops so it's more clear what is
happening.

75680e5d34 videometa: add alignment field

geometry of planes, allowing users to easily know the padded size and

36ce08826e video-info: add gst_video_info_align_full()
When using gst_video_info_align() user had no easy way to retrieve the
padded size and height of each plane.
This can easily be implemented in fill_planes() as it's already called
in align() with the padded height.

Ideally we'd add a plane_size field to GstVideoInfo but the remaining
padding is too small so that would be an ABI break.
