a6f82ba590 utils: improve gst_util_ceil_log2 
According to the following comparison of algorithms, the value
for 0 and 1 was giving an incorrect result.

More information here:
https://github.com/rofrol/codeforces/blob/master/ceil_log2.c

Use a different algorithm which offers better result and keep the
performance.

969b51acb6 flvmux: Don't time out in live mode if no timestamped next buffer is available 
But also don't wait for a buffer on both pads, which might take forever in case
of gaps in one of the streams.

The muxer can only advance the time if it has a timestamped buffer that can be
output, otherwise it will just busy-wait and use up a lot of CPU.

244b00ac08 mpegts: Add custom mapping for vp9 
This is a custom mapping. There isn't much needed apart from that to store vp9
in mpeg-ts since the bitstream is self contained.

Since there are no official specification we don't want people to be mistaken in
believing that. Therefore that mapping is only used in the muxer if the (new)
property `enable-custom-mappings` is set to TRUE.

* The MPEG-TS Stream Type is Private Data (0x6) with the registration descriptor
  set to `VP09`.
* The Access Unit are VP9 frames stored in PES packets
* As there is no emulation prevention byte in VP9 elementary stream, the can be
  misdetection of PES start code. To avoid this, the start of a PES packet must
  be signalled using the Payload Unit Start Indicator in the transport packet
  header

a1c92c0cb1 mpegvideoparse: do not set delta unit flag on unknown frame type 
When encoding an image to mpeg2 video, with something like:
  gst-launch-1.0 encodebin name=e profile=mpegpsmux:video/mpeg,mpegversion=2,systemstream=false ! \
                 filesink location=sample.mpg filesrc num-buffers=1 blocksize=$(stat -c%s sample.png) \
                 location=sample/dts.png ! pngdec ! e.
The only frame's type is set to an invalid value 0
The consequence is that mpegvideoparse sets the delta unit flag on the buffer because
it is not an I frame, then decodebin3 drops this only frame because the delta
unit flag is set and the decoder receives eos before it was able to receive any
encoded data

2080aff70c adapter: Improve documentation for gst_adapter_available() 
When I first read the documentation of gst_adapter_available() and
gst_adapter_available_fast() I got quite confused as it seemed that
both performed the same purpose but one was slower than the other.

I shared it with other people and found they also arrived at the same
wrong conclusion.

Hopefully this patch will make the actual purpose clearer.

4702cae7ff tutorials: gstreamer tools: fix broken webm to ogg transcode pipeline 
The pipeline would error out with not-negotiated. Reason is that
the webm file doesn't have an average frame duration set in the
headers, so matroskademux outputs framerate=0/1, but theora in
Ogg really requires a fixed framerate, so that errors out.

Change example to H.264/AAC in MP4, which is more useful.

36d8243397 ptp: use ip_mreq instead of ip_mreqn for macOS 
To join a multicast the macOS still uses the interface address
from the ip_mreq instead of the ip_mreqn unlike other Linux systems.

So add a new conditional block for macOS to use ip_mreq for IP_ADD_MEMBERSHIP
and ip_mreqn for IP_MULTICAST_IF

This is similar to the fix in the glib for multicast join/leave
operation on macOS

7e9866844f audioresample: skip pointless loop in broken test_fft unit test 
Variable f1 is never used, so just skip that loop for now.

The test has never actually tested actual resampling because of
that bug it seems, and the test fails if fixed to actually resample.

For now we just avoid the pointless 126*12 pipelines that were just
testing the same thing (nothing) over and over again.

6a5a63f051 analytics: Adding abstraction on tensor dims 
Tensor can be row or col major, but it's also possible that the order by we need
to read the tensor with more than two dimension need to be described. The
reserved field in GstTensorDim is there for this purpose. If we need this we

each dimension.

8169863f01 analytics: Make GstTensor more suitable for inline allocation 
GstTensor contained two fields (data, dims) that were dynamicallay allocated. For
data it's for a GstBuffer and we have pool for efficient memory management. For
dims it's a small array to store the dimension of the tensor. The dims field
can be allocated inplace by moving it at the end of the structure. This will
allow a better memory management when GstTensor is stored in an analytics meta
which will take advantage of the _clear interface for re-use.

- New api to allocate and free GstTensor
To continue to support use-cases where GstTensor is not stored in an
analytics-meta we provide gst_tensor_alloc, gst_tensor_alloc_n and
gst_tensor_free that will facilitate memory management.
- Make GstTensor a boxed type
